RESUMO
Data on safety and success rates of ultrasound-guided caudal blockade, performed on sedated children with an uninstrumented airway, are scarce. We performed a retrospective observational study of validated data from April 2014 to December 2020 in a paediatric cohort where the initial plan for anaesthetic management was sedation and caudal epidural without general anaesthesia or airway instrumentation. We examined success rates of this approach and rates of block failure and block-related complications. In total, 2547 patients ≤ 15 years of chronological age met inclusion criteria. Among the 2547 cases, including 453 (17.8%) former preterm patients, caudal-plus-sedation success rate was 95.1%. The primary anaesthesia plan was abandoned for general anaesthesia in 124 cases. Pain-related block failure in 83 (3.2%) was the most common cause for conversion. Complications included 39 respiratory events and 9 accidental spinal anaesthetics. Higher odds of pain-related block failure were associated with higher body weight (adjusted OR 1.063, 95%CI 1.035-1.092, p < 0.001) as well as with mid-abdominal surgery (e.g. umbilical hernia repair) (adjusted OR 15.11, 95%CI 7.69-29.7, p < 0.001), whereas extreme (< 28 weeks) former prematurity, regardless of chronological age, was associated with higher odds (adjusted OR 3.62, 95%CI 1.38-9.5, p = 0.009) for respiratory problems. Ultrasound-guided caudal epidural, performed under sedation with an uninstrumented airway, is an effective technique in the daily clinical routine. Higher body weight and mid-abdominal surgical procedures are risk factors for pain-related block failure. Patients who, regardless of chronological age, had been born as extreme preterm babies are at the highest risk for respiratory events.

Reparixin, a CXCR 1/2 antagonist, has been shown to mitigate ischaemia-reperfusion injury (IRI) in various organ systems in animals, but data in humans are scarce. The aim of this double-blinded, placebo-controlled pilot study was to evaluate the safety and efficacy of reparixin to suppress IRI and inflammation in patients undergoing on-pump coronary artery bypass grafting (CABG). Patients received either reparixin or placebo (n = 16 in each group) after induction of anaesthesia until 8 h after cardiopulmonary bypass (CPB). We compared markers of systemic and pulmonary inflammation, surrogates of myocardial IRI and clinical outcomes using Mann-Whitney U- and Fisher's exact tests. Thirty- and 90-day mortality was 0% in both groups. No side effects were observed in the treatment group. Surgical revision, pleural and pericardial effusion, infection and atrial fibrillation rates were not different between groups. Reparixin significantly reduced the proportion of neutrophil granulocytes in blood at the beginning [49%, interquartile range (IQR) = 45-57 versus 58%, IQR = 53-66, P = 0·035], end (71%, IQR = 67-76 versus 79%, IQR = 71-83, P = 0·023) and 1 h after CPB (73%, IQR = 71-75 versus 77%, IQR = 72-80, P = 0·035). Reparixin patients required a lesser positive fluid balance during surgery (2575 ml, IQR = 2027-3080 versus 3200 ml, IQR = 2928-3778, P = 0·029) and during ICU stay (2603 ml, IQR = 1023-4288 versus 4200 ml, IQR = 2313-8160, P = 0·021). Numerically, more control patients required noradrenaline ≥ 0·11 µg/kg/min (50 versus 19%, P = 0·063) and dobutamine (50 versus 25%, P = 0·14). Therefore, administration of reparixin in CABG patients appears to be feasible and safe. It concurrently attenuated postoperative granulocytosis in peripheral blood.

With the increasing technological development of endoscopy in recent years the diagnosis of and endoscopic therapy for duodenal adenomas has gained in importance. Due to its potentially malignant transformation an effective and safe therapy is necessary. The endoscopic resection has been shown to be safe and effective, even in cases of resection of large duodenal adenomas. Several studies have supported this thesis but are based on relatively small numbers of patients. In our clinic we have performed endoscopic resections of 178 duodenal adenomas over a period of 14 years, including sporadic duodenal adenomas as well as adenomas in familial polyposis syndromes. The aim of this retrospective analysis was to determine the acute complications associated with this technique. The rate of severe complications such as major bleeding or perforations was 9%. Further complications were minor bleeding (15.7%), pain needing treatment with analgesia (6.7%), fever (2.8%) and pancreatitis (0.6%). Summing up our experience with the endoscopic resection of adenomas of the small bowel we also consider the endoscopic resection of duodenal adenomas in most cases as a safe and effective alternative to surgical therapy. Because of the potential complications and their management especially in the resection of large adenomas with a size more than 2 cm, the endoscopic resection should be performed on an inpatient basis in experienced centres.

BACKGROUND: Endovascular repair of ruptured abdominal aortic aneurysm (rAAA) has rapidly gained popularity, but superior results may be biased by patient selection. The aim was to investigate whether suitability for endovascular repair predicted survival, irrespective of technique of repair. METHODS: Two blinded investigators independently evaluated preoperative computed tomography angiograms of a consecutive cohort of patients with rAAA. Patients were categorized either 'suitable' or 'unsuitable' for endovascular repair, if assessments agreed. If assessments disagreed, they were classified 'borderline suitable'. Correlations between endovascular suitability and clinical outcome were adjusted for suspected confounding factors and tested for robustness using sensitivity analyses. RESULTS: A total of 248 patients with rAAA from January 2001 to December 2010 were included, of whom 237 (95·6 per cent) underwent open repair. Seventy patients (28·2 per cent) were classified as 'suitable' and 100 (40·3 per cent) as 'unsuitable' for endovascular repair; 63 (25·4 per cent) were considered 'borderline suitable'. Fifteen (6·0 per cent) could not be assessed and were included in the sensitivity analyses. The postoperative 30-day mortality rate was 15·3 per cent (38 deaths). Multiple logistic regression demonstrated that the odds of perioperative death increased 9·21 (95 per cent confidence interval 2·16 to 39·23) fold for 'unsuitable' rAAA (P = 0·003) and 6·80 (1·47 to 31·49) fold for 'borderline' rAAA (P = 0·014), compared with 'suitable' rAAA. This selection effect was robust across sensitivity analyses and sustained for at least 5 years of follow-up. CONCLUSION: Endovascular suitability was an independent and strongly positive predictor of survival after open repair of rAAA.

OBJECTIVE: To determine whether advanced age was independently associated with prohibitive surgical risks or impaired long-term prognosis after ruptured aortic aneurysm repair. DESIGN: Post-hoc analysis of prospective cohort. MATERIALS: Consecutive patients undergoing ruptured aneurysm repair between January 2001 and December 2010 at a tertiary referral centre. METHODS: Surgical mortality (i.e., <30 days) was compared between octogenarians and younger patients using logistic regression modelling to adjust for suspected confounders and to identify prognostic factors. Long-term survival was compared with matched national populations. RESULTS: Sixty of 248 involved patients were octogenarians (24%) and almost all were offered open repair (n = 237). Surgical mortality of octogenarians was 26.7% (adjusted odds ratio (OR) 2.1; 95% confidence interval (CI), 0.9-5.2) and confounded by cardiac disease. Hypovolaemic shock predicted perioperative death of octogenarians best (OR 5.1; 95%CI, 1.1-23.4; P = 0.037). After successful repair, annual mortality of octogenarians averaged 13.7% vs. 5.2% for younger patients. At 2 years, octogenarian survival was at 94% of the expected 'normal' survival in the general population (vs. 96% for younger patients). CONCLUSIONS: Surgical mortality of ruptured aneurysm repair was not independently related to advanced age but mainly driven by cardiac disease and manifest hypovolaemic shock. An almost normal long-term prognosis of aged patients after successful repair justifies even attempts of open repair, particularly in carefully selected patients.
