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.
