Abstract :
Introduction: Cochlear implantation surgery is usually performed in paediatric patient of 1 to 7 years of age with congenital deaf-mutism. Good results in this surgery are obtained by providing bloodless surgical field with controlled hypotension and postoperative smooth outcome. To anaesthetize these patients, we are using Inj Propofol, Inj fentanyl, Sevoflurane, Dexmedetomidine infusion and muscle relaxants. Dexmedetomidine is an active isomer of medetomidine and an agonist at ?2 u2013adreno receptors. Medetomidine provides perioperative sedation and analgesia thus decreasing other general anaesthetic drug requirement, reduced postoperative pain score, postoperative delirium and other complications.nAim: To determine that inj. Dexmedetomidine infusion is a suitable agent for haemodynamic stability, decreases need of other general anesthetic drug requirement intraoperatively and improves post-operative outcome in cochlear implant surgery.nMaterials and Methods: This study was conducted at a rural tertiary care center, which included 100 samples of pediatric patients (1-7 years of age group) who went through cochlear implant surgeries in last 3 years.nResults: Among all patients, heart rate (HR) remained stable and there was no significant difference between baseline HR and intra-op HR (P=0.3098). The systolic blood pressure (SBP) was decreased significantly compared to baseline reading (P value < 0 xss=removed>nConclusions: Dexmedetomidine provides stable haemodynamics, acceptable hypotensive state, good surgical field and excellent analgesia in pediatric patients undergoing cochlear implant surgery.nu00a0
