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.

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.

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.

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.

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.

ObjectivesTo compare the efficacy and safety of retroperitoneal laparoscopic adrenalectomy (RLA) and transperitoneal laparoscopic adrenalectomy (TLA) in the treatment of large (≥6cm) adrenal pheochromocytomas.MethodsWe 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).ResultsA 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

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.

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.

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

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.

The review discusses the preparation of patients for surgery on the heart and other organs. We considered the importance of introducing a new stage of medical and cardiology rehabilitation — prehabilitation. The results of randomized clinical trials, systematic reviews and metaanalyzes evaluating the effectiveness of respiratory techniques and physical training during the prehabilitation are presented. Particular attention is paid to the involvement of patients in prehabilitation programs before the elective coronary artery bypass grafting. Methodological problems arising in the development of prehabilitation programs are discussed.

To identify risk factors for gastrointestinal, cardiovascular, and thrombotic complications, as well as postoperative bleeding, by individually choosing analgesic anti-inflammatory therapy, including that with nonsteroidal anti-inflammatory drugs, is the most important task in the preoperative preparation of patients with rheumatic inflammatory joint diseases.The paper reviews studies evaluating the efficiency and safety of long-term aceclofenac use in patients who are to undergo joint surgery.

Diseases of the respiratory system (both acute and exacerbations of chronic ones) remain the most frequent non-surgical complications after surgical interventions of various sizes, increasing the duration of the patient»s hospital stay, increasing economic costs and the percentage of deaths. It was shown that respiratory complications developed after abdominal operations increased the risk of 30-day mortality by 10 times. The most common complications include: reintubation, acute respiratory failure, pulmonary edema, atelectasis and pneumonia. The development of respiratory complications is due to the pathology of the respiratory system and respiratory muscles. It is proved that the use of drugs that inhibit neuromuscular conduction in 75 % of cases provokes the development of atelectasis, respiratory muscle dysfunction and reduces respiratory volumes. Respiratory complications are most often caused by hypoxia or hypercapnia. Hypoxia is characterized by a decrease in the partial pressure of oxygen and is well corrected by additional oxygenation. In the first hours after surgery hypoxemia occurs in 50—55 % of cases with a decrease in saturation up to 80 %. Complete normalization of respiratory dysfunction usually occurs 4—6 hours after extubation. Hypercapnia, on the contrary, is characterized by an increase in the partial pressure of oxygen, the phenomena of hyperkalemia and respiratory acidosis. Correction of electrolyte and buffer disturbances is necessary. It is important for the Clinician to remember the need to identify possible risk factors for respiratory complications (modifiable and unmodified) and ways to correct them. Examination of the patient by a therapist before the planned operation, including possible preoperative preparation in the therapeutic departments of a multidisciplinary hospital helps to reduce the frequency of postoperative complications. In this article the authors describe recommendations for evaluation, prevention and diagnosis of respiratory complications in the perioperative period in patients with comorbid pathology.

Enhanced recovery pathways are a novel approach focused on enhancing the care of surgical patients. “Prehabilitation” is the term applied to any intervention administered before surgery to reduce surgery-related morbidity, decrease the length of hospital stay, expedite the return of organ function, and facilitate the patient's return to normal life. A PubMed search was performed with the following key words: enhanced recovery, preoperative preparation, cessation of smoking and euvolemia. The results from this Pubmed search revealed that female patients may have higher levels of anxiety than male patients. Intensive smoking and alcohol cessation 6–8 weeks before elective surgery may reduce the incidence of postoperative morbidity. Preoperative exercise can be effective for reducing the postoperative complications like pulmonary complications and shortening the length of hospital stay. It is safe to allow patients to drink clear fluids up until 2 h before elective surgery (Level II evidence). Perioperative normoglycemia is the single most important factor to prevent surgical site infection. Intermittent pneumatic compression devices and low molecular weight heparin are effective in preventing postoperative thromboembolism. No advantage is gained by preoperative mechanical bowel preparation in elective colorectal surgery. The goal of preoperative fluid management is for the patient to arrive in the operating room in a hydrated and euvolemic state. Mild perioperative hypothermia may promote surgical wound infection by triggering thermoregulatory vasoconstriction, which decreases subcutaneous oxygen tension.

INTRODUCTION: Communication in nursing practice represents one of the basic skill during healthcare services. With continuity, showing concern and interest for the patient, a thrustworthy relationship is built, which contributes to better cooperation and to a more positive outcome of the whole treatment. During the preoperational preparations, nurse is conducting an informational and theraperutical communication through all the phases of healthcare and treatment. In everyday nursing, communication takes place in many relationships. Besides the successfull communication with the patient, a good cooperation between all the members of the health team is indispensable and equally important. AIM: To examine the communication efficency of members in the health team with the patient in preoperative preparation. Materials & methods: The study included 55 operated patients who underwent all elements of preoperative preparation. A questionnaire, specially created for this purpose, was used as a data collection instrument. The survey was conducted anonymously, and each respondent signed a voluntary informed consent. RESULTS: Most patients are very satisfied with all the information they have received on the disease, care, treatment and planned interventions. More than half of the patients felt that there were no aggravating factors in communication with the medical staff, while 1/5 of the respondents felt that the medical staff did not have enough time to communicate with the patients. The patient rating for communication with physicians was 4.87 and for communication with nurses 4.82. CONCLUSION: Communication between health team members and patients while preparing for surgery is of high quality and contributes to good collaboration, greater satisfaction and a more positive outcome.

Objective. Efficacy of endoscopic bronchosanation for prophylaxis of preoperative and postoperative complications in patients with pulmonary tumors. Маterials and methods. There was studied the efficacy of endoscopic photodynamic therapy in accordance to procedure, elaborated by the authors, including injection of the water solution of a methylene blue dye in concentration 0.04% into tracheobronchial tree, irradiated by laser with the wave length 0.63 mcm, independently and in conjunction with a standard anti-inflammatory therapy as preoperative preparation of tracheobronchial tree in patients, suffering pulmonary cancer. In the investigation 181 patients were included, suffering pulmonary cancer Stages II-III, morphologically confirmed, and with coexistent endobronchitis. Results. In accordance to analysis of the pathogenic microflora titer and character in lumen of bronchial tree after preoperative preparation there was established, that while application of independent endoscopic bronchosanation in 55 (87%) observations the pathogenic microflora was absent. While combination of photodynamical bronchosanation in accordance to standard therapy a pathogenic microflora was not revealed in 52 patients. While conduction of a standard preparation without application of a laser therapy microflora was not revealed only in 44.8% observations. Together with the bronchial mucosa metaplasia in some investigated patients the dysplastic changes of bronchial epithelium of various severity degree were registered. Independent endoscopic bronchosanation have leaded to trustworthy lowering of a general rate of the bronchial epithelial dysplasia in the patients tо 36.1%, together with standard anti-inflammatory therapy - tо 42.4%. Conclusion. Application of endoscopic photodynamic bronchosanation in accordance to the proposed procedure in preoperative period in the patients with objective to correct a concomitant endobronchitis, as independent option or together with standard anti-inflammatory therapy, leads to reduction of the endobronchial complications rate after operative treatment for pulmonary cancer, comparing with a control group. Еndoscopic bronchosanation is accompanied by significant lowering of severity of endoscopic signs of coexistent endobronchitits and improvement of mucociliary transport. In accordance to microbiological tests in 87 - 88% of patients a complete sanation of bronchial tree and elimination of main histological criteria of inflammation were noted, while in 67.2 - 100% patients – restoration of normal structure of the bronchial tree mucosa.

The article presents the guidelines developed by the American College of Rheumatology and the American Association of Hip and Knee Surgeons for the perioperative management of patients with rheumatoid arthritis, ankylosing spondylitis, psoriatic arthritis, juvenile idiopathic arthritis, or systemic lupus erythematosus who are undergoing elective total hip or knee arthroplasty. It considers the perioperative use of antirheumatic drug therapy, including disease-modifying anti-inflammatory drugs, biological agents, tofacitinib, and glucocorticoids. All recommendations are conditional and based on the results of retrospective clinical trials, which should be considered when making decisions about perioperative antirheumatic therapy.

The paper describes the first experience with endovascular embolization of artery of kidney graft irreversibly lost its function in fifteen years after transplantation, during preoperative preparation of patient to nefrotransplantatectomy. The purpose of the study – to show the effectiveness of the artery rentgenendovascular embolization of the artery of kidney transplant before the nefrotransplantatektomy as a method of preventing massive intraoperative bleeding and related complications. An angiography and the rentgenendovascular embolization of the artery of kidney transplant executed on the day of surgery allowed us to remove nefrotransplantat without any technical difficulties. The total intraoperative blood loss did not exceed 50 ml.

The aim of study: to estimate the frequency of postoperative complications and the ways of their reduction in patients after performing «large volume» surgical interventions on the example of radical cystectomy (RCE).Materials and methods. The study included 73 patients who underwent RCE. All patients were divided into 2 groups: the main group consisted of 29 patients who remained under the active supervision of the therapist throughout the entire hospitalization and underwent preoperative preparation (cardiac examination, correction and prescription of medication). The comparison group comprised 44 patients whose medical history was retrospectively analyzed. Patients of this group did not undergo advanced therapeutic monitoring, both in the preoperative and postoperative period.Results. In patients of the main group, despite the presence of concomitant pathology in most cases, including cardial pathology, the frequency of postoperative complications was statistically significantly lower than in the comparison group. There were no lethal cases from cardioembolic complications in patients undergoing active therapeutic monitoring. The observation of the therapist throughout the entire hospitalization, as well as the use of the surgical protocol of early activation of the patient, significantly reduced the length of hospitalization, as well as the length of stay in the intensive care unit.Conclusion. The introduction of the program of preoperative preparation and therapeutic postoperative monitoring led to a reduction in the incidence of cardiac death and duration of hospitalization in patients undergoing extensive surgical intervention.

Colorectal cancer is a frequently encountered disease. In most countries, it represents the second leading cause of cancer death. The treatment with radical intent of this condition is surgical. Objective: Through this study, we want to update some data regarding the impact of nutrition and the preoperative mechanical bowel preparation on postoperative complications, in patients who need surgical treatment for colorectal cancer. Material and Method: Relevant articles in the field, contained in international databases were analysed, with no language exclusion, including clinical trials and meta-analyses performed between 1994 and 2015. Conclusions: Preoperative preparation is particularly important in the postoperative evolution of the patients with colorectal cancer and it is based on several main principles: nutritional support, antimicrobial treatment and mechanical bowel preparation.

The efficacy of the protocol of preoperative preparation and accelerated rehabilitation of patients in surgical treatment of thoracic esophageal cancer was aevaluated. The protocol was based on the analysis of short-term results of surgical treatment of 190 patients with esophageal cancer. The algorithm devised at the Moscow Research Institute of Oncology was applied to 30 patients with cancer of the esophagus and cardia. Postoperative complications occurred in 12 (40 %) patients of the study group including surgical complications in 4 patients (chylothorax – 2, failure of the esophageal-intestinal anastomosis – 1, small bowel obstruction – 1). Nonsurgical complications in the absence of surgical ones were noted in 7 patients (pneumonia – 6, heart rhythm disturbances – 1). No lethal outcomes were registered. Patients in the control retrospective group (n=50) underwent surgeries in the same extent after the standard preoperative preparation. Postoperative complications in the control group occurred in 28 (48 %) cases, 4 (8 %) patients died. The median postoperative hospital stay was 11 days (range: 10–29 days) in the study group and 18 days in the control group. Accordingly, the above protocol of preoperative examination and preparation of patients allows the frequency of postoperative complications and lethality to be significantly decreased, thus reducing the hospital stay.

Context: Robot-Assisted Laparoscopic Radical Prostatectomy (RALRP) requires significant preoperative setup time for the room, staff, and surgical platform. The utilization of a dedicated robotics operating room (OR) staff may facilitate efficiency and decrease costs. Aims: We sought to determine the degree to which preoperative time decreased as experience was gained. Materials and Methods: A total of 476 patients with a mean age of 60.2 years were evaluated (11/2006 to 1/2010). Data was assimilated through an institutional review board approved blinded, prospective database. Utilizing time from patient arrival in the OR to robot docking as preoperative preparation, our experience was evaluated. Age, body mass index (BMI), and American Society of Anesthesiologists risk scores (ASA) were compared. Statistical Analysis Used: Analysis of variance; Two-sample t-test for unequal variances. Results: The first and last 100 cases were found to have similar age (P=0.27), BMI (P=0.11), and ASA (P=0.09). The average preoperative times were 66. 4 and 53.4 min, respectively (P

Introduction Causation of surgical site infection (SSI) following craniotomy is multifactorial. Most preventive strategies (including site preparation and antibiotic prophylaxis) revolve around reducing preoperative contamination of the local site. There is little evidence, however, linking site contamination with postoperative infections. This is important given the preference for performing non-shaved cranial surgery. We undertook a prospective study to document the scalp flora in neurosurgical patients in an Indian setting and to assess possible association with SSI. Materials and Methods A prospective study recruited 45 patients undergoing non-shaved clean craniotomies for various brain tumors. Standard perioperative procedures and antibiotic policy were employed. Prior to and immediately following the pre-surgical scrubbing, we collected swabs and evaluated their growth qualitatively. SSI was documented adhering to CDC guidelines. The association of swab-positivity with various parameters (including SSI) was evaluated. Results Pre-scrub positivity was seen in 18 of 44 patients, three of them developed subsequent SSI. Most were known skin contaminants. Five patients had swab positivity after scrubbing, though none of these developed any SSI. Four of these five had pre-scrub positivity. In three the same organisms persisted (two being Staphylococcus aureus), and one had different growth post-scrub, whereas one patient developed new growth (contaminant mycelial fungus) in the post-scrub swab. We did not find any association between swab positivity and SSI. Swab positivity was also not related to hair-length or hygiene. Conclusion Scalp flora in Indian patients is similar to that described. Pre-surgical preparation does not always eliminate this contamination (especially staphylococcus). However, this does not necessarily translate into increased SSI. Moreover, the results also provide objective evidence to support the performance of non-shaved cranial surgery without an undue risk of SSI.

Background: Respiratory failure and crisis is one of major complications of thymectomy in myasthenia gravis patients. There are different medication regimes for preparing these patients for surgery and reducing post-operative side effects. The goal of this study is to compare respiratory complications of oral vs. Parenteral preoperative administration of anticholinesterase agents for thymectomy in myasthenia gravis patients. Methods: This randomized controlled trial included 101 patients in class IIA or IIB of myasthenia gravis according to the Osserman classification system. The control group fasted for eight hours before surgery and oral anticholines-terase agents were replaced with parenteral ones. The case group also fasted for 8 hours before surgery, but pyridostigmine was continued at its usual dose until the time of operation and the last dose was given to patients with a small amount of water in the operating room on the operating bed. Results: There was no statistically meaningful difference between the two groups in terms of age, sex and pathologic findings. In comparison, the mean hospital stay for the case group was 3.98 days and 6.34 for the control group (p value = 0.003). There were eight cases of respiratory crisis or failure (16%) in the control group but only 1 case (2%) was observed in case group (p value = 0.014). Only one patient in the case group required re-intubation after the surgery; however, six patients in control group were re-intubated (p value = 0.053). Plasmapheresis was required for five patients in the control group and one patient in the case group (p value = 0.098). Tracheostomy was performed on two patients in the control group to accommodate prolonged intubation, but none of the case group required this procedure. Conclusion: This study shows that continuing oral anticholinesterase agents up to the time of operation, with the last dose at the operative theater, lowers the incidence of post-operative myasthenia crisis and respiratory failure, need for plasmapheresis and shortens the hospital stay. This method may also decrease the need for re-intubation, mechanical ventilation and tracheostomy, thus decreasing the chance of death resulting from complications of the thymectomy.

Introducción: La preparación preoperatoria de colon es una conducta practicada frecuentemente por los cirujanos; sin embargo, evidencia reciente pone en duda su efectividad. Se decidió realizar una revisión de la información que evalúa su eficacia. Métodos: Se realizó una búsqueda sistemática de la literatura y se evaluaron los artículos de más alta calidad (revisiones sistemáticas) con base en los criterios de calidad de la revista JAMA. Los resultados se analizaron particularmente. Resultados: La preparación preoperatoria de colon aumentó la frecuencia de filtración de la anastomosis. No fue posible discriminar este efecto con base en la localización de la anastomosis. Conclusiones: La conducta de preparación de colon se debe reevaluar en la práctica quirúrgica.Introduction: The preoperative preparation of the bowel is a generalized routine among surgeons; however, recent evidence poses doubts upon its effectiveness. Our group undertook a review of the information pertaining its efficacy. Methods: A systematic search of the articles of best quality was performed (systematic reviews) based upon the quality criteria defined by JAMA. Results were particularly analyzed. Results: Preoperative bowel preparation augmented the rate of anastomotic leaks. It was not possible to discriminate this effect according to the site of the anastomosis. Conclusion: The conduct of routine bowel preparation should be reevaluated.

The past three decades have seen a steady increase in the incidence of colon cancer. Malignant obstruction of the colon is the second most common obstruction after adhesion.

Introduction: We report an unusual case of normotensive pheochromocytoma detected incidentally, presenting a pre-operative management problem. Case Note: A 40-year-old lady with vague abdominal symptoms was initially discovered with a left adrenal incidentaloma by ultrasound abdomen, which was also revealed in computed tomography (CT). After exclusion of all the causes with possible necessary investigations, pheochromocytoma was confirmed with elevated 24 hour urinary metanephrine and normetanephrine. Her blood pressure was in low to normotensive range all throughout. She was attempted to be prepared with combined alpha and beta blockade but could not tolerate this regimen due to symptomatic hypotension. Subsequently, surgical preparation was planned cautiously with alpha-adenergic blockade only. With intensive monitoring, she underwent uneventful left adrenalectomy, and surgical pathology was consistent with pheochromocytoma. Conclusion: This case illustrates an unusual presentation of normotensive pheochromocytoma as adrenal incidentaloma. Pre-operative preparation in these patients can be achieved with alpha-adrenergic blockade, adequate hydration, and liberal salt intake.
