Role of oral gabapentin in attenuating cardiovascular response to laryngoscopy and tracheal intubation.

Abstract

Objectives: To determine the role of 800 mg oral gabapentin in attenuating cardiovascular response to laryngoscopy and tracheal intubation. Study Design: Double Blind Randomized Control Trial. Setting: Independent University Hospital/Independent Medical College, Faisalabad, Pakistan. Period: Six months from January1^st 2019 to June 30^th 2019. Material & Methods: This study included 60 patients which were divided into two equal groups. 800 mg oral gabapentin was given to group I while capsule placebo was administrated to group II patients in pre-operative area one hour prior to surgery. Heart rate, systolic, diastolic and mean arterial blood pressure were taken after induction of anesthesia at base line and then 1,2,3,4,5,10 and 15 minutes after endotracheal intubation. SPSS version 11 was used to analyze the data. Heart rate systolic, diastolic and mean arterial blood pressure were dependent variables while placebo and gabapentin were independent variables. Results: Out of total 60 patients there were 36 (60 %) males and 24 (40 %) females. In group I mean age was 37.1 while in group II it was 36.3. As compare to group II there was decreased cardiovascular response in group I. There was a significant decrease in systolic blood pressure at 1,2 and 10 minutes; diastolic blood pressure at 3 minutes; heart rate at 10 and 15 minutes and mean arterial blood pressure at 3 minutes after induction in group I. Conclusion: Cardiovascular response to laryngoscopy and intubation is significantly reduced with oral gabapentin.
