Randomized clinical study comparing active heating methods for prevention of intraoperative hypothermia in gastroenterology.

Objective: to compare the efficacy of three active heating methods in the prevention of intraoperative hypothermia in open gastroenterological surgeries.

Method: randomized clinical trial with a sample of 75 patients, whose initial body temperature measured by a tympanic thermometer. Esophageal temperature <36ºC was considered hypothermic.

Spinal anesthesia for cesarean section. Use of hyperbaric bupivacaine (10mg) combined with different adjuvants.

Background And Objectives: Combination of local anesthetics (LA) with adjuvants for spinal anesthesia improves block quality and prolongs the duration of analgesia. It was evaluated the maternal effects and neonatal repercussions of sufentanil, morphine, and clonidine combined with hyperbaric bupivacaine for elective cesarean section.

Method: Prospective, randomized, blinded study of 96 patients allocated into four groups: Group I (no adjuvant), Group II (sufentanil 5.
