RESUMO
Objective: To evaluate the effects of the multiple single cannulation technique (MUST) on the outcomes of arteriovenous graft (AVG). Methods: A retrospective study of AVG created between January 2018 and December 2021 at the First Affiliated Hospital of Zhengzhou University was conducted. The clinical data of patients and their follow-up data for venous access were analyzed. Subjects were divided into the MUST group or the non-MUST group according to whether MUST was used. The cumulative patency rate and complication incidence were compared between the two groups. Logistic regression was applied to analyze the influencing factors of applying MUST in AVG. Results: The MUST group included 115 AVG and the non-MUST group, 122 AVG. The 1-year, 2-year, 3-year, and 4-year cumulative patency rates of the MUST group were 100%, 99.1%, 95.2%, 85.4%, and 73.2%, respectively, while those for the non-MUST group were 97.5%, 92.7%, 77.7%, 69.7%, and 50.0%, respectively, with the 2-year and 3-year patency rates showing significant difference (P=0.022, P=0.004). The standard intervention rate expressed in (median [interquartile range]) in the MUST group was significantly lower than that in the non-MUST group (0.46 [0.00, 0.94] vs. 0.97 [0.60, 1.59], Z=-5.808, P<0.001). A total of 24 (20.9%) AVG in the MUST group and 60 (49.2%) AVG in the non-MUST group had a standard intervention rate >1.0 per patient-year, with significant difference between the two groups. Three (2.6%) AVG in the MUST group and 7 (5.7%) AVG in the non-MUST group were complicated by aneurysm (χ 2=20.737, P<0.001). One (0.9%) AVG in the MUST group and 6 (4.9%) AVG in the non-MUST group had graft infection, with the difference between the groups showing no significance (P=0.121). Multivariate logistic regression showed that dialysis in the alliance facilities (odds ratio [OR]=2.713, 95% confidence interval [CI]: 1.698-4.336, P<0.001], and excellent follow-up [OR=2.189, 95% CI: 1.221-3.927, P=0.009] were the influencing factors of applying MUST in AVG. Conclusion: MUST improves the cumulative patency of AVG and decreases the intervention frequency and the incidence of aneurysm without increasing the risk of graft infection.

BACKGROUND: Cerebral perfusion may change depending on arterial cannulation site and may affect the incidence of neurologic adverse events in post-cardiotomy extracorporeal life support (ECLS). The current study compares patients' neurologic outcomes with three commonly used arterial cannulation strategies (aortic vs. subclavian/axillary vs. femoral artery) to evaluate if each ECLS configuration is associated with different rates of neurologic complications. METHODS: This retrospective, multicenter (34 centers), observational study included adults requiring post-cardiotomy ECLS between January 2000 and December 2020 present in the Post-Cardiotomy Extracorporeal Life Support (PELS) Study database. Patients with Aortic, Subclavian/Axillary and Femoral cannulation were compared on the incidence of a composite neurological end-point (ischemic stroke, cerebral hemorrhage, brain edema). Secondary outcomes were overall in-hospital mortality, neurologic complications as cause of in-hospital death, and post-operative minor neurologic complications (seizures). Association between cannulation and neurological outcomes were investigated through linear mixed-effects models. RESULTS: This study included 1897 patients comprising 26.5% Aortic (n = 503), 20.9% Subclavian/Axillary (n = 397) and 52.6% Femoral (n = 997) cannulations. The Subclavian/Axillary group featured a more frequent history of hypertension, smoking, diabetes, previous myocardial infarction, dialysis, peripheral artery disease and previous stroke. Neuro-monitoring was used infrequently in all groups. Major neurologic complications were more frequent in Subclavian/Axillary (Aortic: n = 79, 15.8%; Subclavian/Axillary: n = 78, 19.6%; Femoral: n = 118, 11.9%; p < 0.001) also after mixed-effects model adjustment (OR 1.53 [95% CI 1.02-2.31], p = 0.041). Seizures were more common in Subclavian/Axillary (n = 13, 3.4%) than Aortic (n = 9, 1.8%) and Femoral cannulation (n = 12, 1.3%, p = 0.036). In-hospital mortality was higher after Aortic cannulation (Aortic: n = 344, 68.4%, Subclavian/Axillary: n = 223, 56.2%, Femoral: n = 587, 58.9%, p < 0.001), as shown by Kaplan-Meier curves. Anyhow, neurologic cause of death (Aortic: n = 12, 3.9%, Subclavian/Axillary: n = 14, 6.6%, Femoral: n = 28, 5.0%, p = 0.433) was similar. CONCLUSIONS: In this analysis of the PELS Study, Subclavian/Axillary cannulation was associated with higher rates of major neurologic complications and seizures. In-hospital mortality was higher after Aortic cannulation, despite no significant differences in incidence of neurological cause of death in these patients. These results encourage vigilance for neurologic complications and neuromonitoring use in patients on ECLS, especially with Subclavian/Axillary cannulation.

Right heart failure is a common complication after cardiac surgery, and its mortality remains high. The medical management and veno-arterial extracorporeal membrane oxygenation has shown significant improvement in the majority of cases. However, a minority of patients may still require long-term mechanical circulatory support or heart transplantation. Balloon atrial septostomy is a new method for the prevention and treatment of right heart failure, which may avoid the patient's dependence on mechanical circulatory support. We used this method to try to treat patients with right heart failure after cardiac surgery, and all received good benefits. Therefore, we selected several representative cases to report, in order to guide other qualified cardiac surgeons to carry out relevant clinical practice.

OBJECTIVE: To determine the frequency of appropriate epidural catheter-incision congruency in adult patients undergoing major abdominal surgeries, as well as the frequency of ineffective postoperative analgesia with continuous epidural infusion, side effects, and complications of epidural insertion and epidural catheter infusion. STUDY DESIGN: Observational study. Place and Duration of the Study: Department of Anaesthesiology, The Aga Khan University Hospital, Karachi, Pakistan, from September to November 2022. METHODOLOGY: All adult patients who underwent elective major abdominal surgery under general anaesthesia with epidural analgesia were included in this study. Data were collected by chart review of the patients enrolled in Acute Pain Service for the study period. Intraoperative anaesthesia form, epidural infusion form and all records of acute pain service for the postoperative period were reviewed and recorded. RESULTS: One hundred and eighty-two patients were included in this study. The epidural catheter was inserted congruent to the surgical incision i.e. T10-T11 level or above in 43 (23.6%) patients only. In the postoperative period, overall effective epidural analgesia was observed in 79 (43.4%) of the patients. Motor block in lower limbs was observed in 66 (36.26%) of patients in the immediate postoperative period. CONCLUSION: The present study shows appropriate epidural catheter-incision congruency in only 23.6% of the patients. This could be one of the common reasons for ineffective postoperative pain relief via epidural analgesia in 56.6% of patients. KEY WORDS: Epidural catheter insertion site, Major abdominal surgeries, Postoperative analgesia.

OBJECTIVES: Biliary access refractory to conventional cannulation techniques is a challenging clinical scenario for most endoscopists. The endoscopic-percutaneous rendezvous technique is an optimal alternative with high success rates and low complication rates in expert hands, however its routine use in the West, mainly in Latin America, is still limited. The aim of our study was to evaluate the feasibility, efficacy and safety of endoscopic-percutaneous rendezvous in the management of difficult biliary tract in an endoscopic center in Peru. MATERIALS AND METHODS: Descriptive study - case series type that included 21 patients, with diagnosis of difficult bile duct, all treated by endoscopic-percutaneous rendezvous between July 2017 to July 2020. We evaluated: age, gender, number of previous failed endoscopic retrograde cholangiopancreatography, associated endoscopic findings, rate of successful cannulation, rate of successful resolution of difficult choledocholithiasis, adverse events and procedure-related mortality. RESULTS: The rate of successful cannulation was 100% (21/21). There were 12 cases (57.1%) of difficult choledocholithiasis of which there was a successful resolution rate of 91.6% (11/12). The overall adverse event rate was 4.7% (1/21), which was one case of post-sphincteroplasty gastrointestinal bleeding that was successfully resolved endoscopically only. CONCLUSIONS: Endoscopic-percutaneous rendezvous performed by expert hands is feasible, safe and clinically effective for the management of the difficult bile duct in Latin America.

Aim: To evaluate the effects of double (axillary and femoral) vs. single (axillary) cannulation on early outcomes of acute type A aortic dissection (ATAAD). Materials & methods: Meta-analysis using PubMed/MEDLINE, Scopus, and Cochrane databases through August 23, 2023. Focused on operative mortality, postoperative stroke, re-exploration for bleeding, spinal cord injury, and renal replacement therapy. Results: Among 5 propensity score-matched studies with 2127 patients, double cannulation showed comparable mortality and higher rates of postoperative stroke (pooled odds ratio: 1.69, 95% confidence interval: 1.19-2.39) and need for renal replacement therapy (pooled odds ratio: 1.35, 95% confidence interval: 1.13-1.60) compared with single cannulation. Conclusion: Double arterial cannulation in ATAAD surgery is associated with increased postoperative stroke and renal replacement therapy than single cannulation.
What is this summary about? We studied the optimal way to maintain blood flow during surgery for acute aortic dissection. We focused on comparing the use of one tube placement site in the axillary artery with two sites, both in the axillary and femoral arteries, in five previous studies.What were the results? Using two sites was associated with a higher risk of stroke and need for dialysis after surgery than using only one site.What do the results mean? Adding a tube in the femoral artery for blood flow may increase the risk of complications. It appears that placing the tube only in the axillary artery may be a safer choice for appropriately selected patients having this surgery.

National trends show rapid increases in the use of mechanical circulatory support devices (MCSD) over the last 20 years. While current literature has not proven a mortality benefit in cardiogenic shock as a complication of acute myocardial infarction (AMI-CS) with percutaneous MCSD, these devices are vital to maximizing cardiopulmonary parameters for definitive therapy. To minimize complications, many different techniques have been described including a novel off-pump direct apical cannulation for venoarterial-extracorporeal membrane oxygenation (VA-ECMO). This technique allows early ambulation and avoids peripheral artery access complications but has only been described in small case series. Our case series represents the largest summary of patients (50) using this technique and contains the only comparison data to date. Fifty-four percentage of our patients were Society for Cardiovascular Angiography and Interventions (SCAI) stage D and 22% were arrested before cannulation. We achieved flows on average >5 L/min and most patients required biventricular drainage (86%) and an oxygenator (92%). Thirty day survival was 56% and most survivors were bridged to heart transplant (30%). Our most common complication was bleeding (16%). This technique showed significant improvement in ejection fraction (EF), cardiac output/index (CO/CI), and pulmonary artery pressures. This case series demonstrates the safety and efficacy of this novel technique for central cannulation in cardiogenic shock at large scale within a single institution.

BACKGROUND: Catheter balloon insertion is a common method for cervical ripening and labor induction. Papaverine and its derivatives are musculotropic antispasmodic drugs that directly induce smooth muscle relaxation. Used during childbirth, these drugs have been suggested to shorten the duration of labor. OBJECTIVE: This study aimed to evaluate the effect of administering papaverine before catheter balloon insertion on changes in Bishop scores and on the labor induction-to-delivery interval. STUDY DESIGN: This randomized, double-blinded, placebo-controlled trial was conducted in a single tertiary university-affiliated hospital. Participants were admitted at term for labor induction with an initial Bishop score of ≤6. Participants were randomized to receive 80 mg intravenous papaverine or 0.9% normal saline solution within 30 minutes of Foley catheter balloon insertion. The co-primary outcomes were the difference in Bishop score from before catheter balloon insertion to after removal and the labor induction-to-delivery interval. The secondary outcomes included maternal pain and satisfaction scores, delivery within 24 hours, and neonatal outcomes. Both intention-to-treat and per-protocol analyses were performed. RESULTS: Overall, 110 women were enrolled. In the intention-to-treat analysis, the median difference in Bishop score was greater in the papaverine group than in the placebo group (5 [interquartile range, 1-11] vs 4 [interquartile range, 0-7], respectively; P=.025), and the median catheter balloon insertion-to-delivery interval was shorter in the papaverine group than in the placebo group (21 hours [interquartile range, 6-95] vs 26 hours [interquartile range, 3-108], respectively; P=.031). A higher proportion of women delivered within 24-hours in the papaverine group than in the placebo group (65.5% vs 41.8%, respectively; P=.012). Pain and satisfaction scores, delivery, and neonatal outcomes were similar between the groups. Similar results were found in the per-protocol analysis. CONCLUSION: Papaverine administration before Foley catheter balloon insertion for cervical ripening resulted in improved Bishop scores and shorter catheter balloon insertion-to-delivery intervals.

Tract dilation prior to stent placement is an important step in endoscopic ultrasound-guided hepaticogastrostomy. Mukai and colleagues describe their use of a novel catheter with a longer balloon, which enables one-step tract dilation of the gastric wall, liver parenchyma, and bile duct wall, shortening the procedure and reducing bile leakage.

Continuous peripheral nerve block catheters are simple in concept: percutaneously inserting a catheter adjacent to a peripheral nerve. This procedure is followed by local anesthetic infusion via the catheter that can be titrated to effect for extended anesthesia or analgesia in the perioperative period. The reported benefits of peripheral nerve catheters used in the surgical population include improved pain scores, decreased narcotic use, decreased nausea/vomiting, decreased pruritus, decreased sedation, improved sleep, and improved patient satisfaction.
