Dexmedetomidine (Dexmed) belongs to the imidazole subclass of α2 receptor agonists,
similar to clonidine. It is a potent and highly selective α2 adrenoreceptor agonist,approved
by FDA in 1999 for use in humans for analgesia and sedation. It has a greater affinity for
α2 receptors over α1 (1620:1). Its α2/α1 selectivity ratio is eight times higher than that of
clonidine. All patients underwent a thorough preanaesthetic check-up. Written informed
consent was obtained from each patient after explaining the procedure in a language that
the patient understood. Patients were kept NPO from midnight and advised Tab. Diazepam
(0.1-0.15 mg/kg) and Tab. Rantac 150 mg night before and at 6 AM on the morning of
surgery with sips of water. The mean Etsevo in Group D was 0.29±0.02% and in Group C, it
was 0.31±0.01% upto 5 mins after intubation. Thereafter, it showed an increasing trend in
both the groups.From 5 minutes post insufflation, mean Etsevo (0.48±0.20%) was higher in
Group C as compared to Group D (0.33±0.11%). The difference was very highly significant
upto about 30 minutes of CO2 insufflation. There after mean Etsevo (0.32±0.01%) was
comparable in both the groups till the end of surgery.

LC combines the benefit of complete removal ofgall bladder with the advantage of limited
abdominal incisions, early recovery, shorter hospital stay and less postoperative complication.
Laparoscopic cholecystectomy can be associated with severe complications in the form of
arrhythmias,sudden intraoperative cardiovascular collapse, severe pulmonary edema and
postoperative thromboembolic phenomenon. All patients underwent a thorough
preanaesthetic check-up. Written informed consent was obtained from each patient after
explaining the procedure in a language that the patient understood. Patients were randomly
allocated into 2 groups of 40 each. Mean time to first analgesic in Group D was 4.38 ± 0.86
hrs and in Group C was 2.50 ± 0.68 hrs. On comparing, time to first analgesia was
significantly longer in Group D both statistically and clinically. Nausea and Vomiting was
noted in 5 patients in Group D and 14 patients in Group C. This incidence though statistically
not significant was clinically significant.
