Background: Various professional groups are involved in the daily work of the central operating room with the aim of providing the best possible treatment for each individual using modern medical technology (sociotechnical system) in a cost-effective manner. Ensuring perioperative patient safety is of particular importance. At the same time, the efficient use of the central operating room is essential for the economic success of a hospital. Preoperative preparation is a complex process with many substeps that are often difficult to manage. Historically, the focus has been on retrospective learning from errors and incidents. More recent approaches take a systemic view. A central idea is to consider the mostly positive course of treatment and the adjustments to daily work that are currently required by the people involved (Safety-II). By taking greater account of how the many components of the system interact, processes can be better understood and specific measures derived. This strengthens the system's ability to adapt to changes and disturbances, thus ensuring that goals are achieved. The functional resonance analysis method (FRAM) is an internationally recognized method for modelling work as done compared to work as imagined. This paper presents the application of FRAM to preoperative preparation in a major regional hospital. Objective: Is FRAM suitable for improving process understanding in preoperative preparation? Material and methods: An interdisciplinary project team identified relevant functions of preoperative preparation through document analysis and walkthroughs. Based on this, more than 30 guided interviews were conducted with functionaries. The results were presented graphically and specific information, such as safety-related statements or reasons for the variability of functions, were also presented textually. In the next phase, statements were evaluated and compared with the target model and the job descriptions. Results: The FRAM revealed the process as a complex network of relationships. During the modelling process, a varying degree of centrality and variability of certain functions became apparent. From the observations, the project team selected those with high relevance for patient safety and for the efficiency of the overall process in order to prioritize starting points for deriving measures to increase resilience. These starting points relate either to single functions, such as surgical site marking or to multiple functions that are variable in their execution, such as delays due to nonsynchronized duty times. Conclusion: The FRAM conducted provides valuable new insights into the functioning of complex sociotechnical systems that go far beyond classical linear methods. The awareness of operational processes gained and the resulting dynamic view of interactions within the system enable specific measures to be derived that promote resilient behavior and reduce critical variability, thus contributing to increased patient safety and efficiency.

Prehabilitation comprises multidisciplinary preoperative interventions including exercise, nutritional optimisation and psychological preparation aimed at improving surgical outcomes. The aim of this systematic review and meta-analysis was to determine the impact of prehabilitation on postoperative outcomes in frail and high-risk patients undergoing major abdominal surgery. Embase, Medline, CINAHAL and Cochrane databases were searched from January 2010 to January 2023 for randomised clinical trials (RCTs) and observational studies evaluating unimodal (exercise) or multimodal prehabilitation programmes. Meta-analysis was limited to length of stay (primary end point), severe postoperative complications (Clavien-Dindo Classification ≥ Grade 3) and the 6-minute walk test (6MWT). The analysis was performed using RevMan v5.4 software. Sixteen studies (6 RCTs, 10 observational) reporting on 3339 patients (1468 prehabilitation group, 1871 control group) were included. The median (interquartile range) age was 74.0 (71.0–78.4) years. Multimodal prehabilitation was applied in fifteen studies and unimodal in one. Meta-analysis of nine studies showed a reduction in hospital length of stay (weighted mean difference −1.07 days, 95 % CI −1.60 to −0.53 days, P < 0.0001, I 2 = 19 %). Ten studies addressed severe complications and a meta-analysis suggested a decline in occurrence by up to 44 % (odds ratio 0.56, 95 % CI 0.37 to 0.82, P < 0.004, I 2 = 51 %). Four studies provided data on preoperative 6MWT. The pooled weighted mean difference was 40.1 m (95 % CI 32.7 to 47.6 m, P < 0.00001, I 2 = 24 %), favouring prehabilitation. Given the significant impact on shortening length of stay and reducing severe complications, prehabilitation should be encouraged in frail, older and high-risk adult patients undergoing major abdominal surgery.

The majority of pediatric patients and their parents experience fear and anxiety related to their surgical experience. Traditionally, anesthesia providers addressed this anxiety with pharmacologic therapy, such as benzodiazepines, to provide amnesia and anxiolysis. However, this approach has been questioned due to the potential for developmental neurotoxicity, among other drawbacks. Further, the pharmacological approach does not remove preexisting anxiety that the child and parent experience before arrival and during check-in. Pediatric and parental preparation before surgery is an important step that continues to be inconsistently addressed, particularly in lower-resource community hospitals where the majority of routine pediatric outpatient procedures occur. This care gap provides an opportunity for preanesthesia nurses to intervene with valid, evidence-based preoperative education tools aimed at pediatric patients and their parents. Providing these resources before the day of surgery allows time for child-directed, at-home practice as often as the parent(s) and patient choose. Use of available resources from a leading children's hospital, nurses can create a tailored, developmentally appropriate preoperative education plan for pediatric patients and their parents, providing families with the power to create a positive surgical experience.

Abstract Background Previous studies have demonstrated the efficacy of rehabilitation after a cardiovascular procedure. Especially older and multimorbid patients benefit from rehabilitation after a cardiac procedure. Prehabilitation prior to cardiac procedures may also have positive effects on patients’ pre- and postoperative outcomes. Results of a current meta-analysis show that prehabilitation prior to cardiac procedures can improve perioperative outcomes and alleviate adverse effects. Germany currently lacks a structured cardiac prehabilitation program for older patients, which is coordinated across healthcare sectors. Methods In a randomized, controlled, two-arm parallel group, assessor-blinded multicenter intervention trial (PRECOVERY), we will randomize 422 patients aged 75 years or older scheduled for an elective cardiac procedure (e.g., coronary artery bypass graft surgery or transcatheter aortic valve replacement). In PRECOVERY, patients randomized to the intervention group participate in a 2-week multimodal prehabilitation intervention conducted in selected cardiac-specific rehabilitation facilities. The multimodal prehabilitation includes seven modules: exercise therapy, occupational therapy, cognitive training, psychosocial intervention, disease-specific education, education with relatives, and nutritional intervention. Participants in the control group receive standard medical care. The co-primary outcomes are quality of life (QoL) and mortality after 12 months. QoL will be measured by the EuroQol 5-dimensional questionnaire (EQ-5D-5L). A health economic evaluation using health insurance data will measure cost-effectiveness. A mixed-methods process evaluation will accompany the randomized, controlled trial to evaluate dose, reach, fidelity and adaptions of the intervention. Discussion In this study, we investigate whether a tailored prehabilitation program can improve long-term survival, QoL and functional capacity. Additionally, we will analyze whether the intervention is cost-effective. This is the largest cardiac prehabilitation trial targeting the wide implementation of a new form of care for geriatric cardiac patients.

The article presents updated guidelines developed by the American College of Rheumatology and the American Association of Hip and Knee Surgeons on the perioperative treatment of patients with rheumatoid arthritis, ankylosing spondylitis, psoriatic arthritis, juvenile idiopathic arthritis and systemic lupus erythematosus undergoing elective total hip or total knee arthroplasty. The perioperative use of anti-rheumatic drug therapy, including traditional disease-modi fying antirheumatic drugs, biologic agents, targeted synthetic small-molecule drugs and glucocorticoids. All recommendations are conditional and based on the results of retrospective clinical studies, which should be taken into account in decisionmaking when choosing perioperative antirheumatic therapy.

Surgical resection remains a mainstay in the treatment of malignant solid tumors. However, the use of neoadjuvant treatments, including chemotherapy, radiotherapy, phototherapy, and immunotherapy, either alone or in combination, as a preoperative intervention regimen, have attracted increasing attention in the last decade. Early randomized, controlled trials in some tumor settings have not shown a significant difference between the survival rates in long-term neoadjuvant therapy and adjuvant therapy. However, this has not hampered the increasing use of neoadjuvant treatments in clinical practice, due to its evident downstaging of primary tumors to delineate the surgical margin, tailoring systemic therapy response as a clinical tool to optimize subsequent therapeutic regimens, and decreasing the need for surgery, with its potential for increased morbidity. The recent expansion of nanotechnology-based nanomedicine and related medical technologies provides a new approach to address the current challenges of neoadjuvant therapy for preoperative therapeutics. This review not only summarizes how nanomedicine plays an important role in a range of neoadjuvant therapeutic modalities, but also highlights the potential use of nanomedicine as neoadjuvant therapy in preclinical and clinic settings for tumor management.

Perioperative ischemic stroke is a potentially fatal complication that greatly increases the risk of poor outcome in surgical patients. Despite the relatively low prevalence among patients undergoing non-cardiosurgical and non-neurosurgical interventions (about 0.1–1.0 %), the total number of annually developing perioperative ischemic strokes in patients of this profile is high due to the large number of operations performed in the world. Since the publication in 2014 of the last fundamental work on the prevention of perioperative stroke, approaches to primary and secondary prevention, diagnosis, conservative and reperfusion treatment of ischemic stroke have been seriously modified. The numerous changes that have taken place have created the prerequisites for revising existing approaches to providing care for perioperative ischemic stroke. In 2021, updated documents of foreign researchers/ associations on the problem of perioperative ischemic stroke in non-cardiac and nonneurosurgical patients were published. This review, which consists of two parts, presents current data that summarizes the most relevant information on this topic. The first part of the review outlines the general provisions on perioperative ischemic stroke (definition, risk factors, pathogenesis, predictive models), strategies for pre- and intraoperative prevention.

Thyroidectomy is always regarded as the crucial treatment for Graves' disease, especially in cases of poor efficacy or excessive side effects of antithyroid-drugs and 131I radioiodine therapy. To decrease the incidence of hemorrhage, thyroid storms and other severe complications during the perioperative period, surgeons explore different therapies to prepare for thyroidectomy. We performed a review of preoperative preparation with a focus on the Graves' disease population. Most of the previous schemes are effective, which contributes to the smooth operation of patients, but there is no unified standard for preoperative preparation. This review aims to summarize the preoperative preparation of Graves' disease and the latest developments. Prospective studies with longer follow up-up periods are required to select appropriate preoperative regimens based on personal thyroid statements and to identify target populations of benefit.

Objectives: to evaluate the benefits of delayed conservative myomectomy with the aim of reducing body weight and correcting hematological and metabolic parameters against the background of the use of gonadotropin-releasing hormone (GnRH) agonists and a combination of myo-inositol and D-chiro-inositol (Inofolic combi) in obese patients with metabolic syndrome by comparing this technique with immediate surgery. Materials and methods. The study included 72 patients with uterine fibroids and obesity who required conservative myomectomy. Patients were offered to postpone surgical intervention in order to correct body weight, metabolic and hematological indicators. As a preoperative preparation, patients were recommended to use GnRH agonists (goserelin), inositols, and iron preparations for anemia. Patients were divided into 2 groups: the first group (n = 31) followed all these recommendations, the second group (n = 41) refused to follow the recommendations and postponed surgical treatment. Group 1 underwent surgical treatment 3 months after the start of treatment, group 2 – after the initial consultation. Results. Patients of the first group lost an average of 7.3 ± 1.4 kg of body weight during preoperative preparation, their hemoglobin level increased by an average of 21.78%, and the volume of the largest myomatous node decreased by an average of 21.82%. The duration of the operation was significantly shorter in group 1 (75 ± 3.84 min) than in group 2 (118 ± 5.33 min). Laparotomy in the first group was not performed in any patient, in the second group it was performed in 9 patients (21.95%) (p < 0.05). There was a decrease in the severity of postoperative pain in group 1, (3.4 В± 1.25 points on the visual analog scale), which was significantly lower than in group 2 (5.1 В± 3.4 points). Conclusions. Body weight reduction against the background of the use of GnRH agonists (goserelin) and inositols (Inofolic combi) due to the improvement of the technical conditions of the operation, metabolic and hematological indicators allow to reduce the duration of surgical intervention and the frequency of laparotomies in patients with uterine fibroids against the background of obesity and metabolic syndrome.

Background. Management of patients with infective endocarditis (IE) has changed rapidly in recent years with improvements in diagnostic procedures and early aggressive surgical treatment. The annual incidence of IE in high-income countries has reached 9 cases per 100,000 population. Approximately half of patients with IE require surgical treatment due to severe complications, the most common of which is acute heart failure (AHF), which occurs in 40–60% of cases. Clinical scenarios of IE are often complex, requiring rapid diagnostic measures and early appointment of surgical intervention. The aim. To determine the preoperative algorithm of diagnostic and therapeutic measures in the presence of signs of AHF in patients with IE. Materials and methods. The basis of this study is the clinical data of 311 patients with active IE who underwent examination and treatment at the National Amosov Institute of Cardiovascular Surgery of the National Academy of Medi- cal Sciences of Ukraine from 01/01/2019 to 10/22/2021. The diagnosis of IE was established in accordance with Duke Endocarditis Service criteria proposed in 1994. The average age of the studied patients was 47.9 ± 3.83 (19 to 77) years. Results. In order to determine the degree of AHF at the preoperative stage, all the patients were divided into 4 groups according to the New York Heart Association functional classification. Preoperative clinical data of IE patients with signs of AHF comprised the basis for functional class IV (59 [18.9%] cases) and formed the studied group. For preoperative diagnosis of AHF, cardiohemodynamic data was obtained based on the results of echocardiographic parameters and level of N-terminal pro-B-type natriuretic peptide (NTproBNP). In order to improve the diagnosis of AHF, tactics of preoperative examination of patients with IE were developed. In our study, the following echocardiographic examination results were indicative in the diagnosis of IE complicated by heart failure: detection of vegetations on the leaflets of the left heart valves, end-diastolic index >94.3 ml/m2, end-systolic index >40.8 ml/m2, pulmonary artery pressure >50 mm Hg. The main biochemical marker of AHF in the group of patients with IE was the threshold level of NTproBNP greater than 7473.7 pg/ml. Identified changes in cardiohemodynamic and biochemical indicators became independent indications for hospitalization in the intensive care unit and emergency preoperative preparation. Conclusions. During hospitalization of patients with IE to the cardiosurgical center, the basis of the effectiveness of the provided care is the timely diagnosis of complications of the underlying disease. Based on the results of the work, the protocol for preoperative AHF diagnosis was developed. Critical levels of biochemical and hemodynamic indicators in patients with IE became an independent indication for hospitalization to the intensive care unit and emergency preoperative management. The early start of intensive care for AHF in IE is a fundamental factor that might influence the choice of treatment strategy.

Introduction. The number of patients in the world who have undergone heart transplantation is increasing, with better and longer survival rates, and therefore the number of patients who undergo various surgical interventions after transplantation is also increasing. This presents a challenge for anaesthesiologists. Case outline. A 45-year-old female patient underwent a total thyroidectomy due to suspected thyroid cancer. She had a heart transplant three years earlier. Preoperative preparation included evaluation of cardiac function, consultative examinations by a transplant cardiologist, laboratory and other diagnostic procedures, as well as a detailed analysis of all 20 medications that the patient uses in daily therapy. Common drugs were used for premedication and general endotracheal anaesthesia, with careful dose titration. Medicines were also prepared for the occurrence of heart rhythm disorders, bearing in mind that the heart is denervated, but there was no need for their use. The operation and postoperative course went smoothly and on the third postoperative day the patient was discharged from the hospital in good general condition. Conclusion. Preoperative preparation, anaesthesia, and postoperative treatment of this patient represented a challenge for our team, which was successfully overcome, considering that this is the first case of operative treatment of a patient with a transplanted heart in Serbia.

Background: The proportion of patients over 65 years of age in surgical care is increasing in Germany. Frailty represents a relevant problem in the perioperative care of older patients and has a negative impact on the postoperative outcome. The individual degree of frailty can be influenced. Multimodal prehabilitation concepts can contribute to improving the degree of frailty in the perioperative care of affected patients. As a multidimensional syndrome, frailty is related to the aging process, affects multiple organ systems and typically leads to increased vulnerability to internal and external stressors. This is accompanied by a decrease in homeostatic reserves and resilience, which implies an increased risk of several adverse health outcomes, such as loss of physical function and quality of life. Prehabilitation is described as a multimodal concept to prepare patients preoperatively in the best possible way for elective surgical procedures, thereby minimizing postoperative complications and improving the patientsʼ outcome. Method: Current state analysis of perioperative care of patients over the age of 65 years in relation to frailty assessment and the use of prehabilitation concepts. Conducting a multicenter online survey of anesthesiology experts (n = 189) in German anesthesiology departments. Survey of the preoperative preparation and assessment routine in patients aged 65 years and over using a mixed methods design questionnaire. Objective: The aim of this study was to demonstrate the applied assessments and measures taken for specific perioperative risk assessment and preoperative preparation of patients aged 65 years and over. Results: Specific risk assessments or additional preoperative preparation of patients older than 65 years are currently not carried out routinely. The preoperative risk assessment and preparation usually focus on ascertaining the patient's previous illnesses or diseases. Assessment instruments for assessing frailty and multimodal prehabilitation concepts are not used in clinical practice in a noteworthy quantity. Conclusion: In German clinical practice frailty assessment and structured prehabilitation approaches in perioperative care of older patients are not broadly known or established. Multimodal prehabilitation concepts can positively influence the outcome of older patients. To this end, it should be considered good clinical practice to assess and address frailty in older patients and to establish multimodal prehabilitation approaches tailored to this patient group.

Background: Before starting surgery for the resection of an intracranial tumor, its outlines are typicallymarked on the skin of the patient. This allows for the planning of the optimal skin incision, craniotomy, and angle of approach. Conventionally, the surgeon determines tumor borders using neuronavigation with a tracked pointer. However, interpretation errors can lead to important deviations, especially for deep-seated tumors, potentially resulting in a suboptimal approach with incomplete exposure. Augmented reality (AR) allows displaying of the tumor and critical structures directly on the patient, which can simplify and improve surgical preparation. Methods: We developed an AR-based workflow for intracranial tumor resection planning deployed on the Microsoft HoloLens II, which exploits the built-in infrared-camera for tracking the patient. We initially performed a phantomstudy to assess the accuracy of the registration and tracking. Following this, we evaluated the AR-based planning step in a prospective clinical study for patients undergoing resection of a brain tumor. This planning step was performed by 12 surgeons and trainees with varying degrees of experience. After patient registration, tumor outlines weremarked on the patient's skin by different investigators, consecutively using a conventional neuronavigation system and an AR-based system. Their performance in both registration and delineation was measured in terms of accuracy and duration and compared. Results: During phantom testing, registration errors remained below 2.0mm and 2.0 for both AR-based navigation and conventional neuronavigation, with no significant difference between both systems. In the prospective clinical trial, 20 patients underwent tumor resection planning. Registration accuracy was independent of user experience for both AR-based navigation and the commercial neuronavigation system. AR-guided tumor delineation was deemed superior in 65% of cases, equally good in 30% of cases, and inferior in 5% of cases when compared to the conventional navigation system. The overall planning time (AR = 119 ± 44 s, conventional = 187 ± 56 s) was significantly reduced through the adoption of the AR workflow (p < 0.001), with an average time reduction of 39%. Conclusion: By providing a more intuitive visualization of relevant data to the surgeon, AR navigation provides an accuratemethod for tumor resection planning that is quicker and more intuitive than conventional neuronavigation. Further research should focus on intraoperative implementations. [ABSTRACT FROM AUTHOR]

Objectives: To compare the efficacy and safety of retroperitoneal laparoscopic adrenalectomy (RLA) and transperitoneal laparoscopic adrenalectomy (TLA) in the treatment of large (=6cm) adrenal pheochromocytomas. Methods: We retrospectively collected the clinical data of 130 patients with large pheochromocytoma who underwent RLA or TLA in our hospital from 2012 to 2022. The perioperative parameters and follow-up outcomes of the two groups were compared, and univariate and multivariate analyses were used to evaluate the risk factors of hemodynamic instability (HI). Results: A total of 57 patients underwent TLA and 73 underwent RLA. There was no difference in demographic characteristics such as age, sex and tumor size between the two groups. Compared with the TLA group, patients in the RLA group had shorter operation time (P<0.001) and less estimated blood loss (EBL) (P<0.001). The time to ambulation, time to oral food and time to removal of drainage of RLA group were earlier than those of TLA group. In addition, the hospital stay was shorter in the RLA group than in the TLA group. There were no differences in HI, complications, or blood pressure (BP) improvement between the two groups. The mean follow-up time was 61.4 and 65.5 months, respectively, during which no tumors recurred or metastasized. Multivariate analysis showed that elevated hormone levels and larger tumor size were independent risk factors for HI. Conclusions: Both RLA and TLA are effective treatment methods for large pheochromocytomas, but the perioperative outcomes of RLA are better than that of TLA. Our study demonstrates the superiority of RLA for the treatment of large pheochromocytomas. [ABSTRACT FROM AUTHOR]

Nowadays, the evolution of cardiac surgery is impossible without a continuous improvement of all the treatment stages. One of the promising ways to achieve this goal is the active use of hyperbaric oxygen therapy in the preoperative preparation and postoperative rehabilitation. In this review, we present a short history of the hyperbaric oxygen therapy development in cardiac surgery, the pathophysiological and pathobiochemical mechanisms of its therapeutic effect and the scenarios for its use in the preoperative preparation and postoperative rehabilitation of cardiac surgery patients. The introduction of hyperbaric oxygen therapy into cardiac surgery can improve the results of the surgical treatment, as well as reduce the times of the preoperative preparation and postoperative rehabilitation of cardiac surgery patients, that will significantly increase the quality and efficiency of cardiac surgery.

Abstract Introduction The optimal preoperative preparation for elective colorectal cancer surgery has been debated in academic circles for decades. Previously, several expert teams have conducted studies on whether preoperative mechanical bowel preparation and oral antibiotics can effectively reduce the incidence of postoperative complications, such as surgical site infections and anastomotic leakage. Most of the results of these studies have suggested that preoperative mechanical bowel preparation for elective colon surgery has no significant effect on the occurrence of surgical site infections and anastomotic leakage. Methods/design This study will examine whether oral antibiotic bowel preparation (OABP) influences the incidence of anastomotic leakage after surgery in a prospective, multicentre, randomized controlled trial that will enrol 1500 patients who require colon surgery. The primary endpoint, incidence of anastomotic leakage, is based on 2.3% in the OABP ± mechanical bowel preparation (MBP) group in the study by Morris et al. Patients will be randomized (1:1) into two groups: the test group will be given antibiotics (both neomycin 1 g and metronidazole 0.9 g) the day before surgery, and the control group will not receive any special intestinal preparation before surgery, including oral antibiotics or mechanical intestinal preparation. All study-related clinical data, such as general patient information, past medical history, laboratory examination, imaging results, and surgery details, will be recorded before surgery and during the time of hospitalization. The occurrence of postoperative fistulas, including anastomotic leakage, will be recorded as the main severe postoperative adverse event and will represent the primary endpoint. Ethics and dissemination Ethics approval was obtained from the Chinese Ethics Committee of Registering Clinical Trials (ChiECRCT20200173). The results of this study will be disseminated at several research conferences and as published articles in peer-reviewed journals. Protocol was revised on November 22, 2021, version 4.0. Trial registration ChiCTR2000035550 . Registered on 13 Aug 2020.

Introduction. Literature review search did not show enough information to answer the question concerning the need to remove hair in the external auditory canal as a part of preoperative preparation of the surgical field in middle ear surgery with endaural and transcanal approaches.Aim of the study. To substantiate the removal of hair from the external auditory canal during transcanal and endaural otosurgery.Materials and methods. A prospective randomized study included 2 groups. In the first group, tympanoplasty and stapedoplasty were performed via endaural approach with and without hair removal in the external auditory canal. The effect on the intraoperative overview and postoperative wound healing was assessed. Shunting of the tympanic cavity in the second group, with transcanal approach, have been performed under the control of a microscope and endoscope. The evaluation was done via a questionnaire, it was given to the doctor before and after hair removal separately. Postoperative inflammatory reaction was also assessed.Results. Postoperative wound healing of the external auditory canal in the first group were considered comparable between the main and the control group, and had no complications. In the second group, inflammation was absent in all patients. Hair removal significantly improve the visibility in endaural and transcanal approach.Conclusions. Hair removal from the external auditory canal increases the visibility of the surgical field and facilitates the work of an otosurgeon. It is especially recommended as a preoperative preparation, especially for transcanal surgical interventions on the middle ear under endoscope control.

Introduction. Early detection of patients with obstructive sleep apnea syndrome (OSAS) using preoperative screening is necessary to reduce risks in the perioperative period.The objective was to assess the effect of OSAS on the perioperative management of patients.Methods and materials. 54 patients with a BMI of more than 30 kg/m2 were examined, for whom a bariatric operation was performed as planned. Before the operation, all patients underwent respiratory polygraph with the calculation of the apnea/ hypopnea index (AHI), mean saturation (SpO2 m) during sleep and spirometry.Results. Patients were divided into 2 groups according to AHI: gr. 1 (n=33) with AHI

Aim: Hepatitis B(HBV), Hepatitis C(HCV) and HIV infections are important parenterally transmitted infections. The aim of this study is to determine the seroprevalence of HBsAg, anti-HBs, anti-HCV and anti-HIV in patients with preoperative preparation. Materials and MethodS: Anti-HBs, HBsAg, anti-HCV, anti-HIV tests with chemiluminescent enzyme immune-assay method in a total of 900 patients applied to the General Surgery Clinic and were evaluated preoperatively by Abbott Architect i1000 immunoassay analyzer (Abbott Diagnostics, Illinois, USA) operated according to the manufacturer's instructions. Anti-HBs titer above 10 IU/mL, serum optical density/”cut-off” control optical density (S/Co) ≥1 in HBsAg, anti HCV and anti-HIV tests were accepted as positive. HBV-DNA and HCV RNA tests were performed with real-time PCR method. Results: Anti-HBs test was found to be reactive in 34.11% and nonreactive in 65.89%. HBsAg positivity was 1.0% (9/900), and anti-HCV positivity was 0.33% (3/900). Anti-HIV positivity and HBsAg-anti-HCV association were not detected. Six patients with HBsAg positivity and one patient with anti-HCV positivity were found incidentally during preoperative examinations. Conclusion:As a result of these data, it can be concluded that cost-effective serological tests for HBV and HCV infections performed in the preoperative period are extremely important in the detection of asymptomatic patients. Preoperative screening is important in terms of early diagnosis of patients before complications such as cirrhosis and HCC develop, enabling treatment, as well as enabling healthcare professionals to increase infection control measures while intervening with infected patients, to be more careful in terms of percutaneous injuries, and to reduce the risk of transmission.

Abstract Background Before and after major surgery, access to information in a user-friendly way is a prerequisite for patients to feel confident in taking on the responsibility for their surgical preparation and recovery. Several e-health applications have been developed to support patients perioperatively. The aim of this review was to give an overview of e-health applications designed for self-care associated with surgery by providing a scoping overview of perspectives from providers and patients. Methods We searched the following data sources to identify peer-reviewed quantitative and qualitative studies published between 2015 and 2020: CINAHL, Google Scholar, MEDLINE, PsycInfo, Web of Science, and Scopus. After identifying 960 titles, we screened 638 abstracts, of which 72 were screened in full text. Protocol register: https://doi.org/10.17605/OSF.IO/R3QND . Results We included 15 studies which met our inclusion criteria. Data from several surgical contexts revealed that the most common self-care actions in e-health applications were preoperative preparations and self-assessments of postoperative recovery. Motivational factors for self-care were information, combined with supportive reminders and messages, and chat features. Although there was great variance in research designs and technical solutions, a willingness to engage with and adhere to e-health seemed to increase patients’ self-care activities and thereby accelerate return to work and normal activities. In addition, the need for physical visits seemed to decrease. Even though age groups were not primarily studied, the included studies showed that adult patients of any age engaged in surgical self-care supported by e-health. The providers’ perspectives were not found. Conclusions E-health applications supporting perioperative self-care indicated a positive impact on recovery. However, experiences of healthcare professionals delivering e-health associated with surgery are missing. Additionally, studies based on patients’ perspectives regarding willingness, adherence, and motivation for self-care supported by e-health are sparse. A need for studies examining the supporting role of e-health for self-care in the surgical context is therefore needed.

Identification of patients with obstructive sleep apnea syndrome and high respiratory risk, optimization of the screening algorithm for these patients and administration of preventive non-invasive lung ventilation, makes it possible to prevent the development of perioperative complications, reduce duration of hospital stay and reduce mortality in patients undergoing surgery and bariatric surgery specifically.The objective: to evaluate the effectiveness of STOP-BANG questionnaire for preventive targeted respiratory therapy to reduce the risk of complications in bariatric patients. Subjects and Methods. We examined 60 patients with BMI above 30 kg/m2 referred to elective secondary surgery, the age made 44.2 ± 10.1 years, 23 men and 37 women. Before the operation, patients underwent STOP-BANG questionnaire survey, night respiratory monitoring with the calculation of the apnea/hypopnea index (AHI) and/or saturation during sleep. The standard preoperative examination included clinical and biochemical analyzes.Results. Based on results of STOP-BANG survey, a correlation was revealed between the score and AHI as well as the score and average saturation. The higher score the patients had according to the STOP-BANG questionnaire, the higher AHI was (r = 0.4748, p = 0.002), and the lower mean SpO2 was (r = -0.6958, p < 0.001). Using the ROC analysis, we chose the optimal threshold value - 4 points according to STOP-BANG questionnaire, where the sensitivity of the method was 93% for the AHI, the specificity was 56%, and for the average saturation it was 100% and 63%, respectively. Of the total number of bariatric patients included in the study, 30% required preventive ventilation. In the high respiratory risk group, no significant intraoperative incidents and deaths were reported by the surgical and anesthetic teams. All patients were discharged on time (5‒7 days). Based on the results, a screening procedure has been offered for bariatric patients with high respiratory risk associated with obstructive sleep apnea syndrome.Conclusion. The STOP-BANG questionnaire is a reliable screening tool for high respiratory risk in morbid obese patients. Early diagnosis of high respiratory risk and implementation of preventive ventilation reduces the incidence of perioperative respiratory and cardiovascular complications.

Introduction. Preoperative, in particular, antiseptic, preparation of the external auditory canal (EAC) is an important issue for the otosurgeon to take in mind, especially with endaural approach.The aim of the study is to assess the skin microbiota of the EAC and the effectiveness of antiseptic treatment before endaural intervention.Materials and methods. A prospective study including 19 patients who underwent ear surgery by endaural approach: 10 stapedoplasty; 9 tympanoplasty. Ear swabs culture were taken from all the patients preoperatively and after removing the tamponade. Of the 10 patients with otosclerosis, 5 underwent skin preparation with 10% povidone iodine and a swab culture.Results. According to the microbiological examination results, Staphulacoccus Auricularis prevailed in the first smear - 52.6%. In 5 patients with otosclerosis, in comparison to the 1st swab: one case with absence of microorganisms growth, in the other 4 -decrease in the degree of contamination by half. In the 3rd swab, there was no growth in these patients and in the rest, who didn't undergo antiseptic preparation. Patients, without antiseptic preparation of the ear canal, after tympanoplasty (9 patients) in the second smear, had an increase of contamination (from 105 to 106 CFU/ml).Conclusions. Analysis of the microbiome before and after the operation revealed the growth of predominantly (94.7%) opportunistic microorganisms. Preoperative antiseptic preparation reduces the degree of contamination of the skin, which, in our opinion, prevents complications and improves the healing process.

Objective To analyze retrospectively preoperative evaluation and preparation in Graves′ disease patients with surgical treatment. Methods A total of 126 cases of Graves′ disease in our department from January 2015 to May 2021 were reviewed. Patient information including preoperative preparation, operative mode, postoperative pathological results and complications were collected. Results There were 27 males and 99 females with an average age of(42.4±14.3) years. Surgical indications were Graves′ disease with malignant tumour, airway compression and stenosis, retrosternal goiter, drug intolerance or hyperparathyroidism. There were 75 cases with thyroid papillary carcinoma including 47 cases with papillary microcarcinoma， and 2 cases with follicular carcinoma. Short-term postoperative complications were 11 cases with hoarseness among which 1 case was permanent, and 35 cases with hypocalcemia among which 1 case was permanent. Conclusions It is indicated that preoperative preparation for Graves′ disease requires individualization and refinement, which include iodine preparation, examination of airway condition and neural monitoring, the evaluation of parathyroid function, recurrent laryngeal nerve variation and malignant nodules.

Background: Determining the clinical effort associated with preparing for revision total hip and knee arthroplasty is necessary to maintain the appropriate work relative value unit rating. We have investigated the work done by the orthopedic surgical team in the days and weeks prior to revision hip and knee arthroplasty using a count of time by team members in the electronic medical record (EMR).Methods: EMR audit logs were generated, and preoperative work (POW) was calculated for members of the surgical team for 200 sequential revision cases. Independent samples t-tests were conducted to compare total POW for procedure, age, gender, insurance, and health literacy; significance threshold was set at P = .05.Results: POW was 97.7 minutes (standard deviation [SD] 53.1). Surgeon POW accounted for 10.5 minutes (SD 9.3), nurses for 29.9 minutes (SD 34.2), mid-level providers for 22.1 minutes (SD 17.0), and office technicians for 34.1 minutes (SD 35.2). There was no difference in total POW based on procedure (hip vs knee), age, gender, insurance type, or health literacy.Conclusion: Revision arthroplasty requires substantial preoperative preparation from the surgical team. Most of this is by nurses, mid-level providers, and office staff. This does not seem to be different for hip or knee revisions or by age and gender. EMR audit logs capture the bare minimum POW required to prepare a patient for revision arthroplasty. [ABSTRACT FROM AUTHOR]

Hyperthyroidism is a clinical condition that develops due to the excessive production and secretion of thyroid hormones by the thyroid gland, leading to an elevated concentration of thyroid hormones in tissues. Hyperthyroidism is characterized by low TSH and elevated T3 and/or T4, with the most common causes being Graves' disease, toxic multinodular goiter, and solitary toxic adenoma. T3 is the peripherally active form of thyroid hormone, affecting nearly each tissue and system. The most prominent aspects of hyperthyroidism are related to the cardiovascular system. The treatment of hyperthyroidism includes three options: antithyroid drugs (ATDs), radioactive iodine therapy (RAI), and surgery. Among these treatment modalities, surgery is considered as the most effective one. For patients who are candidates for surgery, preoperative preparation is required to ensure that the thyroidectomy can be performed under optimal conditions. Preoperative preparation should be a combination therapy aimed at preventing the synthesis, secretion, and peripheral effects of thyroid hormones from the thyroid gland. Medications that can be used in this treatment include thionamides, beta-blockers, iodine, corticosteroids, cholestyramine, perchlorate, lithium, and therapeutic plasma exchange. These treatment options can be combined based on the patient's condition. While it is recommended that patients be made euthyroid through preoperative antithyroid treatment to prevent the feared complication, which is the thyroid storm, the supporting evidence is limited. Preoperative treatment does not prevent against thyroid storm whether the patient is euthyroid or hyperthyroid during surgery. Whether surgery should be delayed until biochemical euthyroidism is achieved in hyperthyroid patients remains a topic of debate. Recent studies suggest that thyroidectomy can be safely performed during the hyperthyroid phase by experienced anesthesiologists and surgeons without precipitating thyroid storm or increasing intraoperative and postoperative complications. Although achieving the euthyroid state before surgery is ideal in hyperthyroid patients, it is not always possible. Factors such as allergies to medications, drug side effects, treatment-resistant disease, patient noncompliance, and the urgency of definitive treatment are critical in determining whether hyperthyroidism can be controlled preoperatively. When surgery is necessary in hyperthyroid patients without achieving euthyroidism, the patient's overall condition and comorbidities should be evaluated together by the anesthesiologist, surgeon and endocrinologist, with particular attention to stabilizing the cardiovascular system. We believe that in hyperthyroid patients who are cardiovascularly stable during the hyperthyroid phase, thyroid surgery may not need to be delayed and can be performed safely., Competing Interests: The authors have no conflicts of interest to declare., (© Copyright 2024 by The Medical Bulletin of Sisli Etfal Hospital.)

Introduction: Patients with oropharyngeal masses pose a challenge for an anesthetist in terms of ventilation and tracheal intubation. Thus, preoperative assessment and preparation become an integral part of the management of such anticipated difficult airway cases.Case report: A 45-year-old female presented with growth in the oropharynx causing dysphagia and hoarseness of voice. Clinical examination and investigations predicted a difficult airway. It was managed with fibreoptic nasotracheal intubation with successful perioperative outcomes. Tracheostomy was kept as plan B in case of the CVCI situation.Conclusion: Careful preoperative examination and assessment are required to prepare oneself for a difficult airway. Fibreoptic bronchoscope-guided nasotracheal intubation in a spontaneously breathing patient is a safe and successful technique of airway management in difficult airway cases.

Metabolic surgery is an effective means of achieving significant and sustained weight loss in obese individuals. Bariatric surgery is performed by highly qualified surgeons with extensive experience in this field, but there is no doubt that it can only be performed in highly specialized centers where patient care is performed by a multidisciplinary team. This review pays attention to some important aspects in the preoperative care of patients who are about to have such an operation, with the main emphasis being on the endocrine guidelines. Effective pre-bariatric work-up is a guarantee of successful post-bariatric results. [ABSTRACT FROM AUTHOR]

Introduction: The optimal preoperative preparation for elective colorectal cancer surgery has been debated in academic circles for decades. Previously, several expert teams have conducted studies on whether preoperative mechanical bowel preparation and oral antibiotics can effectively reduce the incidence of postoperative complications, such as surgical site infections and anastomotic leakage. Most of the results of these studies have suggested that preoperative mechanical bowel preparation for elective colon surgery has no significant effect on the occurrence of surgical site infections and anastomotic leakage.Methods/design: This study will examine whether oral antibiotic bowel preparation (OABP) influences the incidence of anastomotic leakage after surgery in a prospective, multicentre, randomized controlled trial that will enrol 1500 patients who require colon surgery. The primary endpoint, incidence of anastomotic leakage, is based on 2.3% in the OABP ± mechanical bowel preparation (MBP) group in the study by Morris et al. Patients will be randomized (1:1) into two groups: the test group will be given antibiotics (both neomycin 1 g and metronidazole 0.9 g) the day before surgery, and the control group will not receive any special intestinal preparation before surgery, including oral antibiotics or mechanical intestinal preparation. All study-related clinical data, such as general patient information, past medical history, laboratory examination, imaging results, and surgery details, will be recorded before surgery and during the time of hospitalization. The occurrence of postoperative fistulas, including anastomotic leakage, will be recorded as the main severe postoperative adverse event and will represent the primary endpoint.Ethics and Dissemination: Ethics approval was obtained from the Chinese Ethics Committee of Registering Clinical Trials (ChiECRCT20200173). The results of this study will be disseminated at several research conferences and as published articles in peer-reviewed journals. Protocol was revised on November 22, 2021, version 4.0.Trial Registration: ChiCTR2000035550 . Registered on 13 Aug 2020. [ABSTRACT FROM AUTHOR]

The influence of various schemes of preoperative preparation for autodermoplasty on the rates of skin graft survival and the duration of hospitalization in patients with burns and wounds of various etiologies was analyzed. Patients were divided into groups and subgroups depending on the preparation scheme. Group I (22 patients) received negative pressure wound therapy (NPWT) during the preoperative period for 5 days in combination with reamberin — intravenous drip at a rate of 40-60 drops/min, 500 ml, once a day for 5 days. Those patients were divided into subgroups: subgroup 1A (17 people) received complex treatment without antibiotic therapy, subgroup 1B (5 people) received antibiotic therapy. Group II consisted of 30 patients, who received vacuum therapy during the preparatory period. Group II patients were also divided into subgroups: 2A (16 people) received NPWT without antibiotics, 2B (14 people) — vacuum therapy together with antibiotic therapy. Group III (comparison, n=52) included patients who were treated using traditional methods, including antibiotic therapy and topical use of various dressings and ointments. Follow-up morphohistological study of wound biopsies was carried out in order to determine the area of fibroblasts, the area of fibroblast nucleus, and the number of vessels. After skin autografting, skin flap survival rate was determined, taking the time of hospitalization into account. Upon comparison of preoperative preparation schemes used for patients with burns and chronic ulcers of various etiologies with a surface area of 1–5% appropriate for skin autografting, the scheme that included NPWT and reamberin for 5 days proved to be the most effective: an improvement in fibroblastogenesis and blood flow to the wound was noted in this group of patients, which was accompanied by an improvement in the skin flap survival rate up to 90.0±9.9%, which, in turn, reduced the duration of patient’s hospital stay — the average duration of the preoperative period was 2.5 times shorter, postoperative — 1.9 times shorter than in the comparison group (p

Background: Before and after major surgery, access to information in a user-friendly way is a prerequisite for patients to feel confident in taking on the responsibility for their surgical preparation and recovery. Several e-health applications have been developed to support patients perioperatively. The aim of this review was to give an overview of e-health applications designed for self-care associated with surgery by providing a scoping overview of perspectives from providers and patients.Methods: We searched the following data sources to identify peer-reviewed quantitative and qualitative studies published between 2015 and 2020: CINAHL, Google Scholar, MEDLINE, PsycInfo, Web of Science, and Scopus. After identifying 960 titles, we screened 638 abstracts, of which 72 were screened in full text. Protocol register: https://doi.org/10.17605/OSF.IO/R3QND .Results: We included 15 studies which met our inclusion criteria. Data from several surgical contexts revealed that the most common self-care actions in e-health applications were preoperative preparations and self-assessments of postoperative recovery. Motivational factors for self-care were information, combined with supportive reminders and messages, and chat features. Although there was great variance in research designs and technical solutions, a willingness to engage with and adhere to e-health seemed to increase patients' self-care activities and thereby accelerate return to work and normal activities. In addition, the need for physical visits seemed to decrease. Even though age groups were not primarily studied, the included studies showed that adult patients of any age engaged in surgical self-care supported by e-health. The providers' perspectives were not found.Conclusions: E-health applications supporting perioperative self-care indicated a positive impact on recovery. However, experiences of healthcare professionals delivering e-health associated with surgery are missing. Additionally, studies based on patients' perspectives regarding willingness, adherence, and motivation for self-care supported by e-health are sparse. A need for studies examining the supporting role of e-health for self-care in the surgical context is therefore needed. [ABSTRACT FROM AUTHOR]

Multiple enhancement strategies have been used to investigate the completion rate of preoperative care in the emergency department. Preoperative patient care was investigated based on the Ministry of Health and Welfare's annual goals in improving medical quality and surgical patients' safety in 2020-2021.The study showed the completion rate of preoperative care was 72.92% in November 2018. The rate of nursing staff acknowledging the standard and accuracy of the preoperative preparation was 81.90%. The following strategies were used to improve the preoperative care: (1) to establish standards of preoperative preparation in emergency department, (2) to develop a preoperative consent checklist, (3) to improve learning by incorporating a game in teaching, (4) to use an example to guide the patients to complete the preoperative consent form, (5) to include the items of preoperative care in a ready package, (6) to develop catchy phrase to help in the preoperative preparation, (7) to use a cartoon to help the staff and the patients acknowledge the preparation of the preoperative care. The completion rate of the preoperative preparation and the rate of the nursing staff acknowledging the standard and accuracy of the preoperative preparation have reached 100%. In conclusion, the multiple enhancement strategies showed an effective measure to improve the preoperative care in the emergency department. Acknowledgment: Our effort has been acknowledged by the surgical ward and was adapted to the surgical patient care. [ABSTRACT FROM AUTHOR]

Introduction: Due to the variation in shape and curvature of the clavicle, plates often have to be adjusted during surgery to acquire a good fit. Poorly fitted plates can cause discomfort, eventually requiring implant removal. 3D-printed replicas of the fractured clavicle can assist in planning of the surgical approach, plate selection and, if necessary, adjustment of the plate prior to surgery. We hypothesized this method of preoperative preparation would reduce implant-related discomfort resulting in a reduced reoperation rate MATERIALS AND METHODS: In a prospective cohort study, perioperative plate handling and clavicle fixation were timed and follow-up data were collected from participants undergoing operative treatment for a midshaft clavicle fracture. The control group (n = 7) received conventional surgery with standard precontoured plates. For the intervention group (n = 7), 3D-printed replicas of the fractured clavicle and a mirrored version of the healthy contralateral clavicle were available prior to surgery for planning of the surgical approach, and for plate selection and contouring. Primary outcome was reoperation rate due to implant-related discomfort. Secondary outcomes were complications and time differences in the different surgical phases (reduction, fixation and overall operation time) RESULTS: More participants in the control group had the plate removed due to discomfort compared to the intervention group (5/7 vs. 0/6; P = 0.012). One participant was excluded from the intervention group due to a postoperative complication; an infection occurred at the implant site. No relevant time difference in surgical plate handling was found between both groups.Conclusions: Preoperative preparation using 3D-printed replicas of the clavicle fracture may reduce implant removal caused by plated-related discomfort. No relevant effect on surgery time was found.Trial Registration: Registered with 'toetsingonline.nl', trial number NL51269.075/14, 17-02-2015. [ABSTRACT FROM AUTHOR]

Introduction. Augmentation urethroplasty using buccal mucosa is currently the optimal method for treating extended urethral strictures. However, this surgery is associated with a fairly high frequency of relapses and complications. One of the reasons that can determine the success or negative outcome of surgery is the morphological structure of the graft, which requires more in-depth research.Purpose of the study. To evaluate the initial morphological state of the buccal mucosa in men and determine the feasibility of its pharmacotherapeutic preparation as a predictor of improving the quality of autograft engraftment in augmentation urethroplasty.Materials and methods. The morphological structure of buccal mucosa fragments was studied in 20 patients with extended strictures of the spongy urethra. The objects of morphological research were intact oral mucosa before augmentation urethroplasty (1 biopsy) and mucosal fragments after 7 days of oral treatment with «Listerine» antiseptic solution (2 biopsies). The biopsy material was examined microscopically using standard staining (hematoxylin-eosin) and immunohistochemical methods.Results. The initial histological structure of the buccal mucosa in every third patient was accompanied by inflammatory infiltration at the level of the subepithelial layer with desquamation of the epithelium. a pronounced increase and strengthening of intercellular contacts in grafts proved histologically and immunohistochemically, which was characterized by pronounced expression of antibodies throughout the thickness of the epithelial layer, after week-long handling of the oral cavity with an antiseptic. At the same time, there is a «self-organization» of the submucosal base by reducing oedema, strengthening intercellular and focal adhesion contacts, with an increase in the components of the vascular bed and the number of vascular «plumules».Conclusion. Thus, a week-long preoperative treatment of the oral cavity allows stopping damage to the epithelium and inflammatory infiltration in the submucosal base with an improvement in its vascularization, which can be regarded as a positive factor for subsequent graft implantation.

Patients with severe postmenopausal genital prolapse (GP) are the most clinically difficult group of women, in which surgical treatment with mesh implants presents significant difficulties due to the duration of lesions amid pronounced structural changes in the tissues of the urogenital tract under conditions of hormone deficiency. That is why it is of particular importance to study the histological characteristics of the vaginal mucosa in women with GP, who must conduct surgical treatment of vaginal access. Aim. To study the histological features of the vaginal mucosa in postmenopausal women with severe GP in preparation for surgical treatment with vaginal access. Materials and methods. The study involved 70 postmenopausal women suffering from GP of stage III, IV in combination with genitourinary menopausal syndrome. Patients were randomized blindly into two groups. The therapy was carried out using vaginal forms of estrogen and progesterone preparations in combination with lactobacilli. In the comparison group, preoperative preparation was not performed. All patients underwent clinical and laboratory examination: general examination and gynecological examination, morphological examination of biopsy samples of the mucous membrane of the anterior vaginal wall, which were obtained during subsequent surgical treatment of GP. Methods of parametric statistics were used. Results. It was established that focal dystrophy, acanthotic severity, keratinization of the vaginal epithelium, moderate inflammation are characteristic morphological changes in the vaginal mucosa in women with postmenopausal GP. Application at the stage of preparation for surgical treatment using vaginal forms, as a result of which estrogen and progesterone enhance the inflammatory process in the ulcerative vagina, reduce dystrophic changes and their severity in relation to complex changes and differentiation of the vaginal epithelium and activation of regeneration processes in tissues. Conclusion. Reducing inflammation and the severity of dystrophic processes in vaginal enemas at the stage of preoperative preparation of women with postmenopausal GP favorably affects the regeneration processes, which in the first place can improve the outcome of surgical treatment.

Сardiac complications are the most frequent non-surgical complications after surgical interventions, increasing the length of the patient’s stay in the hospital, the economic costs and the percentage of deaths. The frequency of patients with cardiovascular diseases who require surgery is also high. Optimization of drug therapy in the perioperative period is one of the factors of successful outcome of the surgical intervention.The pathophysiological basis for the development of many cardiac events in the postoperative period is an increase in the activity of the sympathetic nervous system, which leads to an increase in heart rate (HR) and myocardial oxygen demand. These changes may increase the risk of myocardial ischemia, arrhythmias, and other cardiovascular events in the early postoperative period. For example, the development of myocardial infarction (MI) in the perioperative period leads to an increase in hospital mortality by 15–25 %, and increase in the risk of developing cardiac death in the next few months.The main group of drugs for relieving these effects is beta-blockers (BB). This drug class has a wide range of applications: treatment of angina, arrhythmias, hypertension, MI, heart failure. Currently, there is a large evidence for the possibility and feasibility of using BB in patients undergoing surgery.In this article, the authors highlights the issues of prescribing BB in patients with comorbid pathology in the perioperative period. The analysis and comparison of studies on various aspects of BB use in the perioperative period performed. Currently, there is a mixed opinion about the benefits and risks of perioperative therapy of BB, which causes the high relevance of this issue for discussion.

Cardiac complications are currently the leading cause of early mortality following liver transplantation. Guidelines for the cardiac workup prior liver transplantation are limited. In this review we are discussing commonly modalities used for cardiovascular evaluation of liver transplant candidates.Authors declare no conflict of interest.

Introduction: Ebstein anomaly, a congenital heart defect characterized by a morphological and functional abnormality of the tricuspid valvula while moving the mouth of the tricuspid valvula towards the apex of the right chamber. Case report: A patient aged 39 years on the Department of Surgery was admitted under the image of an acute abdomen and the need for emergency surgical treatment. Routine preoperative preparation, laboratory treatment, examination of internist and examination of anesthesiologist on the part of the part was carried out. He has a history of occasional breathing problems during respiratory infection, a smoker. Clinical status, other than primary problems, is orderly. Operational treatment passed neatly, on the fourth postoperative day the patient complained of suffocation, lack of air and chest pain, translated into intensive care monitored (spo2 87% f about 110/min TA 90/60), blood gas analysis done and laboratory treatment (fibrinogen, D dimer) due to suspected pulmonary thromboembolia consulted cardiologist, dilation of the right atrium seen by ultrasound. Discussion: Non-cardiac surgeries in patients with pre-existing congenital heart defects are high-risk surgeries with increased mobility and mortality in the perioperative period. In accordance with the accompanying pathoanatomical and pathophysiological changes that define the congenital heart defect, a detailed plan must be made - anesthesiological management for each patient separately. Hemodynamic and respiratory stability with avoidance of hypoxia and paradoxical arrhythmias are the basic postulates in patients with Ebstein's anomaly.
