Abstract

Background & objective: Perioperative management of female patients undergoing breast surgery includes a big anesthetic task to adequately manage persistent postoperative pain and postoperative nausea and vomiting (PONV). Pectoral nerve blocks (PECS I and PECS II), while effective in managing postoperative pain, carry a risk of throacoacromial artery puncture with the lateral approach. We evaluated analgesic efficacy of medial approach to PECS I and PECS II blocks in female patients undergoing breast surgery under general anesthesia (GA). Methodology: This is a retrospective study of 116 female patients undergoing modified radical mastectomy that were divided into two groups. Group 1 patients received PECS block with general anesthesia and Group 2 patients received general anesthesia alone. Mean time to extubate, postoperative morphine consumption and PONV were evaluated up to 24 h. Results: Patients who received the PECS block required significantly less postoperative morphine immediately after and 12 h after surgery (P = 0.043 and P = 0.006, respectively). There was no significant difference in PONV between both groups in the first 24 h (P > 0.05). Time to extubation (TTE) was significantly less in Group 1 patients (P < 0.001). Conclusion: The medial approach of PECS I and II nerve block is effective and safe demonstrating reduced postoperative morphine requirement. [ABSTRACT FROM AUTHOR]

Abstract

Background: Intracranial infection after puncture of cerebral hematoma in patients with intracerebral hemorrhage is very common in the department of neurosurgery, yet the relevant risks remain unknown. We attempted to analyze the risk factors of intracranial infection after puncture of cerebral hematoma, to provide insights into the management of patients with intracerebral hemorrhage after puncture of cerebral hematoma.Methods: Patients with intracerebral hemorrhage after puncture of cerebral hematoma treated in our hospital from January 2017 to January 2020 were selected, the related characteristics of intracranial infection and no infection patients were compared. Logistic regression analyses were conducted to analyze the risk factors for intracranial infection after puncture of cerebral hematoma.Results: A total of 925 patients with puncture of cerebral hematoma were included. The incidence of postoperative intracranial infection was 7.03%. There were significant statistical differences between the infected group and the no infection group in the American Association of Anesthesiologists (ASA) grade, length of hospital stay, consecutive operation, duration of surgery, extra-ventricular drainage (EVD) use (all p < 0.05). There was statistically significant difference in the duration of EVD between the infection and no infection groups (p = 0.002), and there was no significant difference in the frequency of EVD insertion between the two groups (p = 0.094). The length of hospital stay≥10 days (OR1.832, 1.062-3.158), consecutive operation (OR2.158, 1.358-3.430), duration of surgery≥4 h (OR1.581, 1.031-2.425), EVD use (OR1.694, 1.074-2.670), and duration of EVD ≥ 7 days (OR2.699, 1.689-4.311) were the risk factors of intracranial infection in patients with intracerebral hemorrhage after puncture of cerebral hematoma (all p < 0.05).Conclusion: Clinical medical workers should take corresponding preventive measures against the different risk factors for prevention of intracranial infection in patient with puncture of cerebral hematoma.

Abstract

Purpose To evaluate the risk factors for developmental coxa vara (DCV) recurrence following valgus osteotomy of the proximal femur. Methods We retrospectively reviewed records of 32 DCV patients (46 hips) treated surgically (2005 to 2012). Recurrencerelated factors, including age at initial surgery, side, sex, fixation methods, diagnosis of coxa vara, premature capital femoral physeal closure and postoperative Hilgenreiner epiphyseal (HE) angle, head-shaft (HS) angle, medial femoral offset and posterior slope angle (PSA) were analyzed. Results At 4.7-year mean follow-up, 12 hip deformities recurred (26%). Postoperative HE angle > 41° and negative offset were statistically significant univariate and multivariate risk factors for the deformity recurrence. Increased PSA was common preoperatively, which accounted for 59% of hips. Postoperative PSA > 20° was associated with a high recurrence rate in the univariate analysis. Age was another univariate risk factor for the recurrence. Recurrence rate was 52% in the < 6.5-year age group versus 4% in the > 6.5-year age group. Other factors were not statistically significantly related to recurrence. Conclusion DCV is a 3D deformity. To prevent recurrence, HE angle should be restored to < 41° in the coronal plane. Sagittal malalignment (abnormal PSA) should be corrected concurrently, so that, the direction of surgical correction is along the true deformity plane. During valgus osteotomy, the distal fragment should be lateralized to maintain a normal mechanical axis. [ABSTRACT FROM AUTHOR]

Abstract

Purpose This retrospective analysis was performed to evaluate whether large bore 9 F puncture sites can be safely closed with the 8 F AngioSeal STS device after endovascular stroke procedures in patients who did or did not receive recombinant tissue plasminogen activator (rt-PA). Methods Out of 161 consecutive endovascular stroke procedures we identified 72 patients who met the inclusion criteria, of whom 46 received rt-PA before the endovascular procedure and 26 did not. All groin complications such as major haemorrhage, failure of the device to close the puncture site, delayed haemorrhage, acute lower extremity ischaemia or necessary vascular surgery as well as infections were recorded. Results Only one patient had delayed groin haemorrhage after closure of the 9 F puncture site with the AngioSeal STS device. There was no significant difference in complications between patients with or without rt-PA treatment. Conclusion The 8 F AngioSeal STS seems to be safe and efficient to close 9 F femoral artery puncture sites, even under active rt-PA thrombolysis. [ABSTRACT FROM AUTHOR]

Abstract

Introduction: The transseptal puncture (TSP) enables access to the left heart, through the fossa ovalis (FO), both in electrophysiology and in cardiac interventional procedures. TSP is usually safe in experienced hands. Sometimes TSP can be technically demanding and carries the risk of severe complications in approximately 1%. While performing a TSP, every effort should be taken in order to avoid complications. In the event of complications, prompt recognition and reaction are essential and a combined ‘heart-team’ management may be the most effective approach. Areas covered: Main TSP-related complications are cardiac tamponade, aortic root puncture, embolic stroke, transient ST elevation of inferior leads and iatrogenic atrial septal defect. A challenging TSP may be expected in presence of difficult IAS-FO anatomies, previous TSP, IAS occluder device and previous IAS surgical repair. Use of echo imaging and special needles (ie., radiofrequency needle and J-shaped guidewire) may avoid TSP-related complications in difficult settings. Expert commentary: Some tools are available to help minimize the risks of TSP. However, their availability might be limited. To increase safety of TSP, an adequate training of physicians, identification of patients in whom it might be difficult and a prompt recognition of complications seem to be the most important background.

Abstract

Background: Arterial puncture, for obtaining an analysis of blood gas, is an interventional procedure often performed in emergency departments and intensive care units. This study compares the ultrasound (US) guided method with the conventional digital palpation method in radial artery puncture (RAP) for blood gas analysis in septic shock patients. Methods: This is a prospective, single-centre study. Septic shock patients over 18 years of age who needed a RAP sample for blood gas analysis were included. Patients with local infection or trauma at the puncture site, arteriovenous fistula, vascular graft, coagulopathy, a positive Allen test, or did not want to participate were excluded. Patients were randomized into two groups and RAP was obtained with either the US-guided method or the conventional method. The main outcomes were success at first entry, the number of attempts before success, and the time to success. Results: The 50 eligible patients were randomized into two groups. First entry success rate for the US-guided group and the conventional group was 80% and 42%, respectively. The number of attempts before success and time to success was significantly higher in the conventional group. Conclusion: The US-guided method has been found to be more successful in terms of first entry success, the number of attempts before success, and the time to success when compared to the conventional method.

Abstract

The pseudoaneurysm of the radial artery is an infrequent complication mainly after iatrogenic procedures, with an increased incidence over the last years. The aim of the current study was to present a rare case of a radial artery pseudoaneurysm that projected through the skin after a single arterial puncture for blood-gas analysis. A 79-year-old man, with a history of atrial fibrillation and coronary heart disease on anticoagulants, was admitted to the cardiological intermediate care unit, with pulmonary oedema due to heart failure deregulation. On the next day, his left radial artery was punctured for blood-gas analysis. No other catheterization of the vessel was executed in the following days. Six days later a pulsatile, palpable mass on the skin surface, over the site of puncture, was recognized. Subsequently a Doppler ultrasound that was performed, confirmed the diagnosis of pseudoaneurysm. The pseudoaneurysm was surgically removed under general anesthesia. The patient was hospitalized for four days for trauma monitoring and intravenous antibiotics and afterwards he was discharged from the Hospital. Three months postoperatively, no sign of recurrence was observed. The pseudoaneurysm of the radial artery is an uncommon complication that might occur even after simple iatrogenic procedures, like after a direct arterial puncture for blood-gas analysis. Therefore, specialists should always be aware of this complication in similar cases.

Abstract

Background. Femoral approach in endovascular surgery remains relevant being, however, associated with the risk of fatal and non­fatal complications. Modern techniques for instrumental haemostasis achieved with the Angio­Seal device (Terumo Corporation, Japan) provide an opportunity to reduce the number of fatal and non­fatal complications. Aim. A multicentre assay of the efficacy and safety of instrumental puncture closure using Angio­Seal devices (Terumo Corporation, Japan) in various settings and clinical situations. Materials and methods . A multicentre retrospective analysis of 1088 use cases of the Angio­Seal device (Terumo Corporation, Japan) for “primary” and “complicated” instrumental haemostasis after femoral access has been conducted for the years 2018–2020. The mean patient age was 62.3 ± 11.6 years, including 845 men (78.0%) and 243 women (22.0%). Five centres for routine and emergency endovascular radiology participated in the study. Results. The Angio­Seal device (Terumo Corporation, Japan) demonstrated a high method efficiency, with a 97.0% success rate of “primary” instrumental haemostasis (1055 of 1088 total successful haemostatic procedures) in various clinical settings. Arterial thrombosis at the approach side had a 3.0% complication rate (5 of 33 observations), all other complication types associated with haemorrhagic events (8 cases) or device malfunction and damage (20 cases). Discussion . The assay conducted suggests that the incidence of “complicated” instrumental haemostasis relates to technical drawbacks of the device application that required advance planning. The key identified prerequisites for a successful Angio­Seal application (Terumo Corporation, Japan) are the alignment of anchor tube­delivery through soft tissue into the vessel lumen and its positioning inside the vessel. Conclusion. The constructive features and instrumental haemostatic technique realised in the Angio­Seal device (Terumo Corporation, Japan) enable an effective and safe primary sealing of arterial puncture site in 97% cases.

Abstract

A vascular closure device is used for hemostasis after a procedure involving an arterial puncture. The increasing frequency of endovascular arterial interventions has caused these devices to play a more important role in clinical practice. FemoSeal is a popular vascular closure device, and its safety and effectiveness have been verified. However, complications still occur in some cases, including even disastrous complications on occasion. Even with little experience, it is possible to reduce the complication rate by using real-time ultrasonography monitoring during the deployment of this device. Based on our experiences, presented herein, we suggest that complications related to FemoSeal could be reduced by using our method.

Abstract

Objective The current study assesses the feasibility of in vitro practice of percutaneous puncture techniques in a pulsatile flow-model. Design Prospective, controlled, randomized study. Setting The percutaneous access to endovascular aortic repair is considered safe, but success rates may be dependent on surgeon experience with the technique. Participants Fourteen vascular surgery trainees and consultants were enrolled and randomized to a study or control group with both groups receiving instructions by a tutor on how to perform ultrasound guided percutaneous puncture and closure using a suture-mediated closure device. The study group received additional hands-on training on a pulsatile flowmodel of the groin and the performance of both groups was then graded. Study group participants were timed during and after their training on the model. Results The study group achieved higher overall grading than the control group on a 5-point scale with higher scores indicating a better performance (mean overall scores 4.0 ± 0.7 versus 2.8 ± 1.0, respectively; p = 0.03). Experienced participants (more than 20 punctures performed before the study) achieved higher overall scores than trainees (3.8 ± 0.4 versus 2.5 ± 0.8, respectively; p = 0.01). Five participants in the study group could deploy and close the ProGlide closure device correctly without the help of a tutor while being graded (71% in the study versus 0% in the control group; p = 0.02). Study group participants improved their overall score from 3.2 ± 0.9 to 4.0 ± 0.7 during training (p = 0.02). Time needed to complete the puncture and closure reduced from 456 seconds on average before, to 302 seconds after training (p Conclusions Study group participants could improve their overall score while working on the simulator. More experienced participants performed better during the simulation, which may indicate the model to be life-like and a potential skills assessment tool. Simulation training may be a valuable adjunct to traditional forms of training when teaching an endovascular technique but is limited by its reliance on simulators and demo devices.

Abstract

Introduction Incidental arterial puncture is one of the main complications associated with central venous catheter placement. Manual compression to achieve hemostasis in subclavian and carotid artery punctures is often ineffective because of the anatomical arterial position. Accidental cannulation has traditionally been treated with open surgery or endovascular treatment, but such procedures are not exempt from complications. Objectives Report our experience with ultrasound-guided off-label use of Perclose ProGlide (Abbott Vascular Inc., Santa Clara, CA, USA) in patients with iatrogenic arterial cannulation. Methods Six unstable patients with accidental arterial catheterization during placement of a central venous catheter: five of them in the subclavian artery and one in the right common carotid artery. Ultrasound-guided percutaneous closure was performed at bedside using a Perclose ProGlide (Abbott Vascular Inc., Santa Clara, CA, USA). Results All patients underwent duplex ultrasound 6, 12, 24, and 48 h postprocedure, and no complications associated with percutaneous closure (embolism, ischemia, stenosis, or arterial occlusion, bleeding, pseudoaneurysm, etc.) were described. Conclusions Accidental artery puncture during central venous catheterization is an uncommon situation but can be effectively managed by using percutaneous vascular closure device. It is a reliable alternative that should be considered as a first-line approach before endovascular or open surgery, specially in patients with unstable conditions in which it is possible to be performed without transfer to an operation room.

Abstract

Central venous cannulation (CVC) is common and necessary in pediatric intensive care. However, this procedure is not without risks or complications. Although CVCs have classically been placed following anatomical landmarks, the use of ultrasound guidance has largely replaced the latter, given its better profile of efficacy and safety, demonstrated at least in adult populations.To compare the effectiveness and safety in the insertion of femoral central venous catheters guided by ultrasound (US) versus the anatomical method (LM) in critical care pediatric patients.100 patients were randomized: 50 were assigned to the US group and 49 to the LM group. In the LM group the traditional method consisted in palpating the femoral artery pulse as a; in the US group the CVC was inserted using a real time technique. Success at the first attempt, overall success in cannulation, number of attempts and arterial puncture were the variables studied in both groups.Success at the first attempt and overall success in cannulation were significantly higher in the US group versus the LM (US 42% vs. LM 18%, p 0.011, US 84% vs. LM 51% p0.001, respectively). The incidence of puncture of the femoral artery was lower in the US group (LM 12 vs. US 5, p 0.056) without achieving statistical significance.According to our results, the placement of central venous access via the femoral approach should be preferably performed under ultrasound guidance, however, further studies in larger populations are needed to confirm this findings.

Abstract

Background: The radial artery is superficially palpable and easily accessible, making it the preferred site for arterial cannulation. Various placement techniques are available for radial artery catheter insertion. However, catheter insertion is sometimes difficult and requires multiple attempts, especially by inexperienced trainees, leading to technical failure and insertion-related complications. Guidewire-assisted cannulation is a simple and effective technique, but this maneuver requires practice. The main objective of this study was to compare the effects of a direct arterial puncture and a guidewire-assisted cannulation technique on the success rate of radial artery cannulation by inexperienced trainees.Methods: This study was a prospective, single-center, single-arm clinical trial with a historical control. Sixty patients with an American Society of Anesthesiologists physical status of I to III underwent elective surgery requiring radial artery cannulation. In the guidewire-assisted cannulation group (GW group), thirty radial artery cannulations were performed by inexperienced surgical residents using a guidewire-assisted cannulation technique. In the direct arterial puncture group (DP group), 30 patients underwent radial artery cannulation with a direct arterial puncture technique by inexperienced anesthesiology residents. The primary outcome was the success rate. Results: There were no differences in the baseline blood pressure or comorbidities between the two groups. Overall, the success rate of radial artery cannulation in the GW and DP groups were 90% and 50%, respectively (P = 0.001). The success rate of first-attempt cannulation in the GW and DP group were 66.7% and 26.7%, respectively (P = 0.002). The total procedural performance time was significantly shorter in the GW than DP group.Conclusion: The guidewire-assisted cannulation technique achieved a higher success rate than the direct arterial puncture technique when performed by inexperienced trainees.Trial registrationThe trial was registered on Thai Clinical Trials Registry (TCTR20200601004).

Abstract

Background Since the femoral artery frequently overlaps the femoral vein, femoral central venous catheterization carries the risk of arterial puncture in pediatric patients. Aims We evaluated the angle range of leg abduction with external hip rotation to minimize the overlap between the femoral artery and vein in pediatric patients undergoing general anesthesia. Methods Eighty-two pediatric patients who underwent elective surgery with general anesthesia were enrolled in this study. Using ultrasonography, patients were divided into groups N (patients with non-overlap) and O (patients with continuing overlap) based on the presence of non-overlap range between the femoral artery and vein. The range minimizing the overlap was defined as the range without overlap in group N and as the range presenting the overlap that was less-than-half of the radius of the femoral vein in group O. By increasing the angle of leg abduction with external hip rotation, the starting and ending angles minimizing the overlap were found using ultrasonographic images. Results The angle range of leg abduction with external hip rotation minimizing the overlap between the femoral artery and vein was defined as the range from the maximum 99% confidence interval of starting angles to the minimum 99% confidence interval of ending angles, which was between 45° and 65° in group N and between 48° and 58° in group O, respectively. Conclusion Positioning patients in a range of 48° and 58° leg abduction with external hip rotation can minimize the overlap between the femoral artery and vein. However, the clinical usefulness of this positioning for femoral venous catheterization remains to be seen.

Abstract

Background This case report describes a subclavian vein cannulation that inadvertently led to an arterial puncture with the catheter tip radiologically seen at the level of the aorta. This case emphasizes the importance of postprocedural imaging and the disadvantages of not using ultrasound guidance in central venous catheterization. Case presentation A 24-year-old Caucasian man with diabetes mellitus type 1 presented himself to the emergency department due to abdominal pain accompanied by nausea and vomiting. The patient’s vital signs revealed blood pressure of 84/53 mmHg, heart rate of 103 beats per minute, respiratory rate of 18 breaths per minute, and temperature of 98.2 °F (36.7 °C). On physical examination, he was found to have dry oral mucosa with poor skin turgor, with diagnostics showing that he was in diabetic ketoacidosis after running out of insulin for 2 days. The patient was transferred to the intensive care unit to receive a higher level of care. Unfortunately, due to difficulty of peripheral line placement, only a gauge-22 cannula was secured at the left dorsum of the hand. Efforts to replace the current peripheral line were unsuccessful, and a decision to perform a central vein cannulation via the internal jugular vein was made. This was futile as well due to volume depletion, prompting a subsequent right subclavian vein route attempt. The procedure inadvertently punctured the arterial circulation, leading to the catheter tip being visible at the level of the aorta on postprocedure X-ray. The subclavian line was immediately removed with no adverse consequences for the patient. A right femoral line was successfully placed, and continuous management of the diabetic ketoacidosis ensued until normalization of the high anion gap was achieved. Conclusion Utilization of real-time ultrasound guidance via the subclavian approach could have allowed for direct visualization of needle insertion to the anatomical structures, guidewire location, and directionality, all of which can lead to decreased complications and improved cannulation success compared with the landmark technique. A leftward direction of the catheter seen on postprocedural X-rays should raise high suspicion of inadvertent catheter placement and immediate correction. This complication should have been prevented if ultrasound guidance had been used.
