Randomized Controlled Trial Comparative Study Clinical TrialEffect of amino acid solutions on intraoperative hypothermia and postoperative shivering. Comparison of two anesthetic regimens.
Intraoperative hypothermia is a major adverse effect of general anesthesia. The different anesthetics may influence thermoregulation differently. Proteins or amino acids have been postulated to stimulate heat production. The purpose of this study is to compare the effects of intraoperative administration of amino acid solutions on intraoperative hypothermia and postoperative shivering in two different anesthetic regimens. ⋯ The anesthetic method may influence the thermic effect of amino acids under general anesthesia. Propofol anesthesia has more thermogenic effect than isoflurane when combined with amino acid solutions.

Randomized Controlled Trial Comparative Study Clinical TrialChanges in serum S100beta protein and Mini-Mental State Examination after cold (28 degrees C) and warm (34 degrees C) cardiopulmonary bypass using different blood gas strategies (alpha-stat and pH-stat).
The effect of cardiopulmonary bypass temperature and blood gas management on the brain is still controversial. This study was designed to compare the changes in S100beta protein concentration and Mini-Mental State Examination in patients undergoing cold (28 degrees C) vs. warm (34 degrees C) cardiopulmonary bypass using different blood gas strategies (alpha-stat and pH-stat). ⋯ These results support the use of warm CPB (34 degrees C) in patients undergoing coronary artery bypass surgery regardless of the type of blood gas strategy.

Randomized Controlled Trial Comparative Study Clinical TrialIncidence and severity of postoperative nausea and vomiting are similar after metoclopramide 20 mg and ondansetron 8 mg given by the end of laparoscopic cholecystectomies.
Ondansetron has a well documented antiemetic prophylactic effect, whereas in most studies of postoperative nausea and vomiting (PONV), metoclopramide is less efficacious. This can be attributed to the short-lasting effect of metoclopramide when a low dose is given at the beginning of surgery. We wanted to test a 20-mg dose of metoclopramide given at the end of surgery, using ondansetron 8 mg as a reference. ⋯ Metoclopramide 20 mg i.v. given at the end of laparoscopic cholecystectomy resulted in a similar incidence of PONV compared with ondansetron 8 mg. The patients receiving metoclopramide had less pain than the patients receiving ondansetron.

Randomized Controlled Trial Comparative Study Clinical TrialCost-effectiveness of analgesia after Caesarean section. A comparison of intrathecal morphine and epidural PCA.
Patient-controlled analgesia (PCA) techniques and intrathecal morphine are the most widely used treatments for post-Caesarean section pain. However these methods have not been compared with respect to analgesic quality and cost differences. ⋯ It was concluded that epidural PCA induced better pain relief, caused less nausea/vomiting but was more expensive than intrathecal morphine.

Randomized Controlled Trial Clinical TrialIntravenous fluids warming by mattress is simple and efficient during pediatric surgery.
Temperature control is essential during pediatric surgery. The effectiveness of two methods of warming intravenous (i.v.) fluids to preserve normothermia was compared during abdominal surgery. ⋯ The increase in CT was more pronounced in patients where fluids were warmed under the warming mattress (Group M) than in those with fluids warmed by a coil warming device (Group T). The elevation in CT seen in Group M is associated with an increase in infusion fluid temperature at the line just before the i.v. cannula. Both methods of fluid warming (by placing the i.v. tubing under warming mattress and by using a fluid warming system) effectively preserved normothermia during abdominal surgery in children.
