Abstract

Background:The major problems during laparoscopic surgery are related to the
cardiopulmonary adverse effects of pneumoperitoneum, systemic carbon dioxide absorption,
and patient positioning. Due to the requirement of steep head-up position, the chances and
severity of unwanted hemodynamic responses such as hypertension and tachycardia are much
higher in laparoscopic cholecystectomy when compared with other laparoscopic
surgeries.Objective: The goal of anesthetic management in laparoscopic surgeries is to
minimize these hemodynamic responses along with adequate depth and pain control with the
target of minimal stress response and early discharge.
Materials & Methods:The present study was conducted in MLB Medical College and
hospital, Jhansi,UP.Participants of eithersex with ASA physical status grade I & II, aged 20
to 50 years and planned for elective laparoscopic cholecystectomy under general
anaesthesiawith tracheal intubationwere included in this study.This study was carried out in
100 participants. All selected participants under study were randomely divided into two
groups depending on the premedication used.Group A patients were given i.v.
dexmedetomidine in a dose of 1ug/kg over a period of 10 minutes, diluted with 100ml normal
saline,20minutes prior to induction of anaesthesia.Group B patients were given oral
pregabalin 75 milligrams with sips of water 1.5 hour before induction. Data was analysed in
SPSS 17.0 using unpaired students t test.
Result:We found that Systolic Blood Pressure and Heart Ratewere decreased after intubation
in both the groups but fall was significantly greater in group A when compared to group B
.There was also significant fall in Mean Arterial Pressure after intubation in group A as
compared to group B.
