RESUMEN
BACKGROUND: Perioperative anaphylaxis is rare but is associated with significant morbidity. This complication has been well described in France by the GERAP (Groupe d'Etude des Réactions Anaphylactiques Périopératoires), a network focused on its study. The epidemiology of perioperative anaphylaxis is evolving, influenced by environmental factors and clinical practice. The aim of this study was to update the epidemiology of perioperative anaphylaxis in France. METHODS: This multicentre retrospective study was performed in 26 allergy clinics of the GERAP network in 2017-8. RESULTS: There were 765 patients with perioperative anaphylaxis included. Most cases were severe, with 428 (56%) reactions graded as 3 or 4 according to the Ring and Messmer classification. Skin test results were available for 676 patients, with a culprit agent identified in 471 cases (70%). Neuromuscular blocking agents were the main cause of perioperative anaphylaxis (n=281; 60%), followed by antibiotics (n=118; 25%) and patent blue dye (n=11; 2%). Cefazolin was the main antibiotic responsible for perioperative anaphylaxis (52% of antibiotic-related reactions). Suxamethonium and rocuronium were the main neuromuscular blocking agents responsible for perioperative anaphylaxis with 7.1 (6.1-8.4) and 5.6 (4.2-7.4) reactions per 100,000 vials sold, respectively, whereas cefazolin-related cases were estimated at 0.7 (0.5-0.9) reactions per 100,000 vials sold. CONCLUSIONS: Our results confirm that most commonly identified triggering agents remain neuromuscular blocking agents. Reactions to antibiotics, particularly cefazolin, are becoming increasingly frequent. The origin of sensitisation to cefazolin is unknown, as no cross-sensitisation has been described, and it should be the subject of further study. Perioperative anaphylaxis should be followed over the years and understood given the changing triggers. CLINICAL TRIAL REGISTRATION: ClinicalTrials.gov (NCT04654923).

INTRODUCTION: Dental injury is the most common incident associated with anaesthesia. Regarding recent recommendations on informed consent and changes in airway management practices, a large series of claims related to dental injury has not been recently described. The aim of this study was to analyse a recent database in order to describe the characteristics of dental injury in France. METHODS: A database that prospectively collected claims reported to Le Sou Médical-MACSF between January 2003 and December 2010, was analysed. Five hundred and ninety-two cases were reported. The following characteristics were analysed: number and type of teeth injured, mechanism of injury, anaesthetic procedure, risk factors and dental outcome after injury. RESULTS: Amongst the 1514 claims related to anaesthesia, 592 (39.2%) were classified as dental damage. Preoperative informed consent concerning possible perioperative dental injury was documented in only 34.8% of patients. Only one tooth was affected in 65.2% of patients, dental bridge injury in 12.8% of cases and damage to two or more teeth in 14% of patients. Incisors were involved in 50% of cases. Fracture was the most common type of injury (64.2%). Poor dentition was the most common risk factor (23.1%) followed by difficult intubation (15.4%). Both risks were combined in only 7.6% of cases. Tracheal intubation was the highest risk procedure (41.6%). CONCLUSION: Dental injury remains the most common anaesthesia-related claim. Dental examination and documentation in patient medical files requires improvement and better informed consent on dental injury risk needs to be provided to patients.

INTRODUCTION: Airway management and tracheal intubation are routinely performed in paediatric anaesthesia and yet are associated with preventable adverse events. The McGrath® MAC is a video laryngoscope with a curved blade similar to the Macintosh blade, which has not been previously described in first intention paediatric tracheal intubation. We aimed to compare direct laryngoscopy to the McGrath® MAC video laryngoscope among novice laryngoscopists. METHODS: Six paediatric anaesthesia residents with novice skills in paediatric laryngoscopy were randomly assigned to perform tracheal intubation using either direct Macintosh laryngoscopy (DL) or the McGrath® MAC video laryngoscope (MM) as the first attempted device in children weighing between 10 and 20kg without difficult intubation. RESULTS: Our study enrolled 132 children between August 2013 and April 2015. The time to intubation was shorter in the DL group (n=67) compared to the MM group (n=65) with 42s (35-50) versus 48s (43-58) P=0.002. The time to best view was similar between the two groups (10s [7-16] versus 10s [8-15]; P=0.50). The tube passage time was shorter with DL (29s [25-35] versus 35s [30-45]; P=0.0002) and either Cormak & Lehane grade or Percentage Of Glottis Opening (POGO) scores were similar between groups. Minor reversible respiratory adverse events were similar between groups: 12 in the DL group (17.9%) versus 12 in the MM group (18.5%). DISCUSSION: McGrath® MAC video laryngoscopy, when performed by a novice laryngoscopist on easy-to-intubate children, is associated with longer intubation times.
