Abstract
Laparoscopic surgery had several advantages over conventional surgery for the patient. Dexmedetomidine due
to its distinct properties can be used as an anaesthetic adjuvant in the form of intravenous infusion. We studied the use of
low dose dexmedetomidine infusion in laparoscopic surgery and its effect on hemodynamics, sedation scores and
analgesic requirements. After the approval of the hospital ethics committee of Mahatma Gandhi Memorial Hospital
Warangal, Telangana state 90 patients, aged 25 to 52 years, ASA grade I to II, and scheduled for laparoscopic
cholecystectomy, were included in the study. Control Group C received normal saline0.9%, Group D1received
dexmedetomidine 0.2 μg/kg/h and Group D2 received dexmedetomidine 0.4μg/kg/ h intravenously. There was no
significant difference in preoperative hemodynamic parameters between the groups. In control Group significant
haemodynamic stress response was seen following laryngoscopy, tracheal intubation, creation of pneumoperitoneum and
extubation.Indexmedetomidine groups, the haemodynamic response were significantly attenuated. In addition,
dexmedetomidine provides lighter sedation and reduces the post‑operative analgesic requirements without any significant
adverse effects. Dexmedetomidine 0.4mcg/kg/h was significantly more effective than 0.2mcg/kg/h and control group.
