A retrospective study of suspected anaphylactic reactions during anesthesia in Belgium

© Acta Anaesthesiologica Belgica, 2018. Background: Since 2008, Belgian anesthe siologists can report suspected anaphylactic reactions during anesthesia on the website of the Society for Anesthesia and Resuscitation of Belgium (SARB). Material & Methods: We analyzed the database retrospectively, covering a period from January 2008 to May 2013. Results: Out of 97 cases, two were excluded because of insufficient data. Fifty-six % of cases were reported by the 2 hospitals that conducted the survey. The incidence of severe reactions was higher in regional hospitals than in university hospitals. Respiratory symptoms were more frequent in patients with a history of respiratory disease. Mast cell tryptase (MCT) after the reaction was measured correctly in only 54% of cases, and was positive in 66% of cases (MCT > 13.5 figfL). Basal MCT was measured in 64% of patients. Skin testing was done in 72% and was positive in 51 (75%) of them. Most frequently incriminated agents were neuromuscular blocking drugs (NMBDs) (63%) and antibiotics (18%). Cross-sensitivity between NMBDs occurred in 78% of cases. A complete investigation (MCT at 30-90 min, basal MCT at distance from the reaction, and skin testing) was conducted in 38% of cases. Conclusion: There was probably severe underreporting of suspected anaphylactic reactions in Belgium. Moreover, in a majority of cases, necessary investigations were carried out incompletely. Underreporting and incomplete investigation increases the risk for new episodes of anaphylaxis during subsequent anesthesia.status: publishe

The hip fracture surgery in elderly patients (HIPELD) study to evaluate xenon anaesthesia for the prevention of postoperative delirium: a multicentre, randomized clinical trial

Background: Postoperative delirium occurs frequently in elderly hip fracture surgery patients and is associated with poorer overall outcomes. Because xenon anaesthesia has neuroprotective properties, we evaluated its effect on the incidence of delirium and other outcomes after hip fracture surgery. Methods: This was a phase II, multicentre, randomized, double-blind, parallel-group, controlled clinical trial conducted in hospitals in six European countries (September 2010 to October 2014). Elderly (75yr-old) and mentally functional hip fracture patients were randomly assigned 1:1 to receive either xenon- or sevoflurane-based general anaesthesia during surgery. The primary outcome was postoperative delirium diagnosed through postoperative day 4. Secondary outcomes were delirium diagnosed anytime after surgery, postoperative sequential organ failure assessment (SOFA) scores, and adverse events (AEs). Results: Of 256 enrolled patients, 124 were treated with xenon and 132 with sevoflurane. The incidence of delirium with xenon (9.7% [95% CI: 4.5 -14.9]) or with sevoflurane (13.6% [95% CI: 7.8 -19.5]) were not significantly different (P¼0.33). Overall SOFA scores were significantly lower with xenon (least-squares mean difference: 0.33 [95% CI: 0.60 to 0.06]; P¼0.017). For xenon and sevoflurane, the incidence of serious AEs and fatal AEs was 8.0% vs 15.9% (P¼0.05) and 0% vs 3.8% (P¼0.06), respectively. Conclusions: Xenon anaesthesia did not significantly reduce the incidence of postoperative delirium after hip fracture surgery. Nevertheless, exploratory observations concerning postoperative SOFA-scores, serious AEs, and deaths warrant further study of the potential benefits of xenon anaesthesia in elderly hip fracture surgery patients.
