Comparison of equipotent doses of Ramosetron, Ondansetron, and sub-hypnotic dose of Propofol for prevention of postoperative nausea and vomiting in laparoscopic cholecystectomy.

Background And Aims: For prevention of Postoperative nausea vomiting (PONV) in laparoscopic surgery, ramosetron is a selective 5-HT3 receptor antagonist with higher receptor affinity and slow dissociation than ondansetron. We compared these 2 drugs with propofol which has also shown antiemetic properties. The aim was to study ondansetron, ramosetron, and propofol with respect to incidence of PONV, its severity and the need for rescue antiemetic along with the side effects.

Comparative analysis of epidural bupivacaine versus bupivacaine with dexmedetomidine for vaginal hysterectomy.

Background: Dexmedetomidine a new drug, which is alpha-two agonist, is recommended by manufacturers as an adjuvant in epidural analgesia and anesthesia.

Aims: To study the effects of dexmedetomidine on quality and efficacy of the epidural bupivacaine 0.5% for vaginal hysterectomies, by studying the onset of action, duration of action, highest dermatomal level achieved, degree of motor blockade, intraoperative and postoperative anesthesia and analgesia achieved.
