Comparative Study of the Effect of Warming at Various Temperatures on Biochemical, Hematologic, and Hemodynamic Parameters During Spinal Fusion Surgery Under Intravenous Anesthesia.

Background: Perioperative inadvertent hypothermia (PIH) commonly occurs after major surgical procedures under local or general anesthesia and increases the risk of complications such as organ failure, hypoperfusion, and peripheral vasoconstriction, as well as adverse postoperative outcomes, such as wound infection and increased surgical bleeding.

Objectives: We hypothesized that the intra-operative warming may affect these complications and thus, we aimed to compare the most appropriate temperature of the warmer to decrease patients' complications.

Methods: The present randomized clinical trial investigated 90 patients undergoing total intravenous anesthesia in posterior spinal fusion surgery, randomly divided into two groups of 45.

Oral clonidine premedication reduces nausea and vomiting in children after appendectomy.

Objective: Clonidine is an α2-agonist which is used as a sedative premedication in children. There are conflicting results in the published literature about the effect of clonidine on the incidence of post operative nausea and vomiting (PONV). We therefore decided to evaluate the effect of oral clonidine given preoperatively on the incidence of PONV in children after appendectomy.

Acupressure using ondansetron versus metoclopramide on reduction of postoperative nausea and vomiting after strabismus surgery.

Objective: To compare the clinical efficacy of acupressure with treatment induced by ondansetron and metoclopramide on reduction of the severity of postoperative nausea and vomiting (PONV) after strabismus surgery.

Methods: There were 200 patients with ASA classes I-II, ages 10 to 60 years old, who underwent strabismus surgery that were included in this randomized, prospective, double-blind, placebo-controlled trial. Group I was the control, group II received metoclopramide 0.
