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.

Randomized Controlled Trial Comparative Study[A comparative study between ultrasound and neurostimulation guided axillary brachial plexus block].
Conceição DB, Helayel PE, Oliveira Filho GR - A Comparative Study between Ultrasound- and Neurostimulation-Guided Axillary Brachial Plexus Block. ⋯ The success rate and time to perform the blockade were similar in ultrasound- and neurostimulation-guided axillary plexus block for hand surgeries. The rate of vascular puncture was higher in neurostimulation-guided axillary plexus block.

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.

Randomized Controlled Trial Comparative Study[Effects of epidural analgesia and continuous lumbar plexus block on functional rehabilitation after total hip arthroplasty].
BAKGROUND AND OBJECTIVES: Pain after total hip arthroplasty (THA) is severe and it is aggravated by movements, which requires an effective analgesic technique that allows early mobilization, participation in rehabilitation activities, and fast functional recovery. The objective of this study was to compare the effects of epidural and perineural patient-controlled analgesia (PCA) of the lumbar plexus on functional rehabilitation of patients undergoing THA. ⋯ The greater effectivity of epidural analgesia did not translate in improvement of the rehabilitation process nor did it decrease the time necessary to achieve end goals.
