Comparative Study[Comparison of hemodynamic changes in acute intoxication with intravenous bupivacaine and ropivacaine in swine].
Pure levorotatory ropivacaine was introduced to provide a safer alternative to bupivacaine in regional blocks. The objective of this study was to compare the hemodynamic repercussions after the intravenous administration of both agents in swine, simulating the intoxication that can be seen during regional blocks in humans. ⋯ In swine, ropivacaine caused less hemodynamic repercussions than bupivacaine when the same doses were administered intravenously.

Randomized Controlled Trial Comparative Study[Effective anesthetic volumes in sciatic nerve block: comparison between the parasacral and infragluteal-parabiceps approaches with 0.5% bupivacaine with adrenaline and 0.5% ropivacaine].
The volume and mass of local anesthetics (LA) affect the success rate of peripheral nerve blocks. Thus, the main objective of this study was to determine the volumes of local anesthetics in parasacral and infragluteal-parabiceps sciatic nerve block (SNB). ⋯ In sciatic nerve block, significantly smaller volumes were necessary in the parasacral than in the infragluteal-parabiceps approach, but volumes did not differ between both LAs.

Randomized Controlled Trial Comparative Study[Prophylaxis of postoperative nausea and vomiting in morbidly obese patients undergoing laparoscopic gastroplasties: a comparative study among three methods].
Videolaparoscopic bariatric surgeries are associated with a high incidence of postoperative nausea and vomiting. Those events can lead to significant morbidity, increase hospitalization costs, as well as patient dissatisfaction. The objective of this study was to compare different prophylaxis protocols of postoperative nausea and vomiting in videolaparoscopic gastroplasties. ⋯ The incidence of postoperative nausea and vomiting in videolaparoscopic gastroplasties was more effectively reduced with the association of ondansetron and dexamethasone than with each drug separately.

Difficult airways require fast action by the anesthesiologist often requiring complementary devices to ensure patent airways. However, several of those devices are expensive and require training in order to be used. The bougie, a simple and disposable device can also be manufactured by the anesthesiologist, making it a low cost tool. ⋯ The bougie has shown to be a valuable tool in the armamentarium of the anesthesiologist, and it is indicated in a wide range of situations.

Randomized Controlled Trial[Supplemental oxygen and the incidence of perioperative nausea and vomiting in cesarean sections under subarachnoid block].
Supplemental oxygen can reduce the incidence of postoperative nausea and vomiting in patients under general anesthesia. The objective of the present study was to determine the efficacy of supplemental oxygen to reduce the incidence of perioperative nausea and vomiting in elective cesareans under subarachnoid block. ⋯ The administration of supplemental oxygen from anesthetic induction until the end of the surgery did not reduce the incidence of intra- and postoperative nausea or vomiting in women undergoing cesarean section under subarachnoid block.
