Epidemiology and complications of anaesthesia in the French centres that participated to NECTARINE: A secondary analysis.

INTRODUCTION: Neonatal and infant anaesthesia are associated with a high risk of perioperative complications. The aim of the current study was to describe those risks in France using the French data from the NECTARINE study. MATERIAL AND METHODS: Data from the French centres that participated to the NECTARINE study were analysed. The primary goal of the study was the description of patients' characteristics, procedures and perioperative management and their comparison with the results of the European NECTARINE study. Secondary outcomes were the description of major perioperative complications and death. RESULTS: Overall, 926 procedures collected in 15 centres (all teaching hospitals) were analysed. Comparison between the French and European NECTARINE cohorts found few differences related to patients' characteristics and procedures. The rate of interventions for critical events (respiratory, haemodynamic, and metabolic) was similar between the two cohorts. Near-infrared spectroscopy monitoring was used in 12% of procedures. Nearly none of the thresholds for these interventions met the published standards. By day 30, complications (respiratory, haemodynamic, metabolic, renal, and liver failure) and death were observed in 14.4% [95% CI 11.6-16.4]% and 1.8% [95% CI 1.1-2.9] of cases, respectively. DISCUSSION: Although the health status of the patients in the French cohort was less severe, procedures, management and postoperative complications and mortality rates were similar to the European cohort. However, thresholds for interventions were often inadequate in both cohorts. Efforts should be undertaken to improve the knowledge and use of new monitoring devices in this population.

Anaesthesia management during paediatric robotic surgery: preliminary results from a single centre multidisciplinary experience.

INTRODUCTION: Paediatric robotic surgery is gaining popularity across multiple disciplines and offers technical advantages in complex procedures requiring delicate dissection. To date, limited publications describe its perioperative management in children. MATERIAL & METHODS: We retrospectively analysed the prospectively collected anaesthetic data of the first 200 robotic-assisted surgery procedures in our paediatric university hospital as part of a multidisciplinary program from October of 2016 to February of 2019. Anaesthetic technique and monitoring were based on guidelines initially derived from adult data. We examined adverse events and particular outcomes including blood loss and analgesic requirements. RESULTS: Fifty-one different surgical procedures were performed in patients aged 4 months to 18 years (weight 5-144 kg). Operative times averaged 4 h and conversion rate was 3%. Neither robotic arm nor positional injury occurred. Limited access to the patient did not lead to any complication. Hypothermia was frequent and mostly self-limiting. Negative physiological effects due to positioning, body cavity insufflation or surgery manifesting as significant respiratory and haemodynamic changes occurred in 14% and 11% of patients, respectively. Overt haemorrhage complicated one case. Eighty per cent of 170 patients did not require level 3 analgesics postoperatively, while thoracic and certain tumour cases had greater analgesic requirements. CONCLUSION: These preliminary results show that paediatric robotic surgery is well tolerated with a low bleeding risk and that major intraoperative events are uncommon. A consistent anaesthetic approach is effective across a broad range of procedures. Analgesic requirements are low excluding thoracic and some complex abdominal cases. Future studies should focus on the rehabilitative aspects of robotic surgery technique.
