The Effect of Intraoperative Dexmedetomidine Versus Morphine on Postoperative Morphine Requirements After Laparoscopic Bariatric Surgery.

Background: Dexmedetomidine is an α receptor agonist with sedative and analgesic properties. During bariatric surgery, its use may reduce postoperative opioid requirements, reduce their side effects, and improve quality of recovery. The aim of this prospective randomized controlled trial was to compare the effect of dexmedetomidine bolus and infusion versus morphine bolus given prior to the end of laparoscopic bariatric surgery.

Dexamethasone with either granisetron or ondansetron for postoperative nausea and vomiting in laparoscopic surgery.

In a prospective randomized double-blind study, we compared the effectiveness of dexamethasone 8 mg with either granisetron 1 mg or ondansetron 4 mg in the prevention of postoperative nausea and vomiting in patients undergoing laparoscopic surgery. Hundred ASA I and II patients scheduled for laparoscopic surgery were enrolled in the study and 84 patients completed it. Following induction of anesthesia, group I (n=42) received granisetron 1 mg and dexamethasone 8 mg, group II (n=42) received ondansetron 4 mg and dexamethasone 8 mg.

Anesthesia for laparoscopy: a review.

Laparoscopy is the process of inspecting the abdominal cavity through an endoscope. Carbon dioxide is most universally used to insufflate the abdominal cavity to facilitate the view. However, several pathophysiological changes occur after carbon dioxide pneumoperitoneum and extremes of patient positioning.

Intraperitoneal and intravenous routes for pain relief in laparoscopic cholecystectomy.

Background: Postoperative abdominal and shoulder pain are the most common complaints after elective laparoscopic cholecystectomy. Postoperative pain is multifactorial in origin, and therefore multimodal therapy may be needed to optimize pain relief.

Methods: We conducted a double-blind study where patients were randomly allocated to 1 of 5 groups of 20 patients each.

A combination of alfentanil-lidocaine-propofol provides better intubating conditions than fentanyl-lidocaine-propofol in the absence of muscle relaxants.

Purpose: To compare the ease of tracheal intubation without the use of muscle relaxants following an alfentanil-lidocaine-propofol sequence vs a fentanyl-lidocaine-propofol sequence.

Clinical Features: In 80 ASA I and II adult patients undergoing elective laparoscopic surgery, we compared the intubating conditions following alfentanil 20 microg x kg(-1), lidocaine 1.5 mg x kg(-1), propofol 3 mg x kg(-1) (Group I; n = 40) vs fentanyl 2 microg x kg(-1), lidocaine 1.
