The Effect of Ketamine with Remifentanil for Improving the Quality of Anaesthesia and Recovery in Paediatric Patients Undergoing Middle-Ear Ventilation Tube Insertion

Abstract

This prospective randomized study evaluated the effects of ketamine with remifentanil to improve the quality of anaesthesia and postoperative recovery, following brief procedures, in 60 paediatric patients undergoing middle-ear ventilation tube insertion (MEVTI). Patients were randomly assigned to either ketamine 2 mg/kg intravenous [i.v.] bolus plus normal saline by i.v. infusion (K group, n = 30) or ketamine 2 mg/kg i.v. bolus, plus remifentanil 0.15 μg/kg per min i.v. infusion (KR group, n = 30). Parameters that were assessed included intraoperative patient movement, surgeon satisfaction, anaesthesia time, total ketamine dose, postoperative recovery time, agitation and side-effects. Intraoperative patient movement scores were significantly lower, and surgeon satisfaction scores were significantly higher, in the KR group than in the K group. Time to recovery was significantly shorter in the KR group than in the K group. In conclusion, remifentanil was a good adjuvant to ketamine, improving the quality of anaesthesia and postoperative recovery in children undergoing MEVTI.
