Randomized Controlled TrialIntraoperative oxygen administration does not reduce the incidence or severity of nausea or vomiting associated with neuraxial anesthesia for cesarean delivery.
Supplemental oxygen may reduce postoperative nausea and vomiting after general anesthesia. We designed this study to evaluate the efficacy of supplemental oxygen administration for reducing nausea and vomiting in women having neuraxial anesthesia for cesarean delivery. ⋯ Administration of supplemental oxygen during cesarean delivery with neuraxial anesthesia does not decrease the incidence or severity of intraoperative or postoperative nausea or vomiting.

Randomized Controlled Trial Comparative StudyA prospective, randomized comparison between combined (deep and superficial) and superficial cervical plexus block with levobupivacaine for minimally invasive parathyroidectomy.
Minimally invasive parathyroidectomy (MIP) can be performed under cervical plexus block (CPB). Superficial CPB has been reported to be easier to perform with similar efficacy and less anesthesia-related complications than combined deep and superficial CPB. In this study, we compared the efficacy of superficial and combined (deep and superficial) CPB in patients undergoing MIP. ⋯ Superficial CPB is an alternative to combined block for MIP.

Randomized Controlled Trial Multicenter StudyClevidipine effectively and rapidly controls blood pressure preoperatively in cardiac surgery patients: the results of the randomized, placebo-controlled efficacy study of clevidipine assessing its preoperative antihypertensive effect in cardiac surgery-1.
Clevidipine is an ultrashort-acting, third-generation IV dihydropyridine calcium channel blocker that exerts rapid and titratable arterial blood pressure reduction, with fast termination of effect due to metabolism by blood and tissue esterases. As an arterial-selective vasodilator, clevidipine reduces peripheral vascular resistance directly, without dilating the venous capacitance bed. In this randomized, double-blind, placebo-controlled multicenter trial we evaluated the efficacy and tolerability of clevidipine in treating preoperative hypertension. ⋯ Clevidipine was effective in rapidly decreasing blood pressure preoperatively to targeted blood pressure levels and was well tolerated in patients scheduled for cardiac surgery.

Randomized Controlled TrialThe preoperative use of gabapentin, dexamethasone, and their combination in varicocele surgery: a randomized controlled trial.
We investigated the effects of gabapentin and dexamethasone given together or separately 1 h before the start of surgery on laryngoscopy, tracheal intubation, intraoperative hemodynamics, opioid consumption, and postoperative pain in patients undergoing varicocele operations. ⋯ Gabapentin and dexamethasone administered together an hour before varicocele surgery results in less laryngeal and tracheal intubation response, improves postoperative analgesia, and prevents postoperative nausea and vomiting better than individual administration of each drug.

Randomized Controlled TrialThe Narcotrend monitor and the electroencephalogram in propofol-induced sedation.
The Narcotrend (NCT) is a one-channel electroencephalogram (EEG) monitor of the level of sedation. It is based on a visual EEG scoring system, which was developed by Loomis and modified by Kugler, to yield a visual expert classification (VEC) scheme for differentiation of six levels of sedation (A-F), which are subdivided into 16 substages. We designed the present study to test whether results of the automated classification of one-channel NCT input reflect those from VEC of five-channel EEG. ⋯ As the algorithm of NCT is proprietary and not accessible to the public, reasons for the observed differences between NCT and VEC cannot be analyzed and explanations must remain speculative.
