Abstract

Objectives: Sympatholytic properties of dexmedetomidine have many advantages to use in general anesthesia especially in pediatric age group undergoing cochlear implant surgeries. This study is designed to compare the effects of bolus dose of dexmedetomidine followed by infusion with placebo in cochlear implant surgeries for quality of hypotensive anesthesia with hemodynamic stability and incidence of complications in pediatric age group particularly emergence delirium with sevoflurane.

Methodology: 60 pediatric patient of ASA grade I or II with congenital or acquired deafness of age ranging from 2 to 8 years scheduled for cochlear implant surgery were included in this study.

Group D were administered dexmedetomidine 0.5 μg/kg in 100 ml 0.9% NaCI over 10 min followed by infusion of dexmedetomidine at 0.5 μg/kg/h and Group P was given placebo only i.e. 0.9% NaCl 100 ml over 10 min followed by infusion at 2 ml/h. Heart rate (HR) and mean arterial pressure (MAP) at different time interval, intraoperative fentanyl and propofol consumption, surgeons’ satisfaction score and complications, particularly incidences of emergence delirium were recorded.

Statistical analysis: Mean with standard deviation of various parameters of both groups was compared using student’s t test were analyzed.
