Randomized Controlled Trial
Evaluation of the reliability of preoperative descriptive airway assessment tests in prediction of the Cormack-Lehane score: A prospective randomized clinical study.
In this study we investigated and compared the predictive values of different airway assessments tests including thyromental height measurement test, which has been recently suggested, in difficult laryngoscopy (Cormack and Lehane [C-L] scores 3 and 4). In addition, we compared the effectiveness of methods and C-L scores, by IDS, in terms of predicting difficult intubation. ⋯ The present study demonstrates the practicality of TMH as a digitalized test however the clinical benefits of TMH in daily medical practice are drawn into question. The additional variable of race may have had some bearing on this and further studies, larger in patient sample size, may need to use different methodology concerning age-, sex-, and race-dependent variables in evaluating these tests.

Multicenter Study Comparative Study Clinical Trial
Fast-track anesthesia in patients undergoing outpatient laparoscopic cholecystectomy: comparison of sevoflurane with total intravenous anesthesia.
The use of short-acting anesthetics has introduced a "fast-track anesthesia" concept in outpatient surgery which provides discharge of the patients from operation room directly to the phase II recovery area without entering into postanesthesia care unit. The aim of this prospective and randomized study was to compare general anesthesia using sevoflurane with propofol-remifentanil-based total intravenous anesthesia (TIVA) for fast-track eligibility in patients undergoing outpatient laparoscopic cholecystectomy. The secondary aim was to compare 2 discharge scoring systems: White's Fast-Tracking Scoring System (WFTSS) and Modified Aldrete Scoring Systems (MASS) with regard to postanesthesia care unit bypass rate and postoperative problems. ⋯ The ratio of fast-track eligible patients was higher and times to fast-track eligibility were shorter in group TIVA compared with group sevoflurane (82.1% vs 57.5% and 8 minutes vs 12 minutes; P<.05). The primary factors that have inhibited fast-tracking were desaturation, hemodynamic instability, pain, and postoperative nausea and vomiting, respectively. Postoperative nausea and vomiting presented a major difference in the rate of fast-track ineligibility between groups (4 patients in group sevoflurane, whereas none in group TIVA; P<.05). The fast-track ratio was lower with the WFTSS compared with MASS in group sevoflurane (57.5% vs 77.5%, P<.05), but similar in group TIVA.

This study aimed to review research on the effects of nonsteroidal anti-inflammatory drugs (NSAIDs) on β-endorphin. NSAIDs are commonly used as anti-inflammatory and analgesic drugs. They are well known for inducing peripheral analgesia by inhibiting cyclooxygenase (COX). ⋯ However, the specific signal transduction pathways between prostaglandin E2 or NSAIDs and β-endorphin are still not quite clear. Whether NSAIDs can lead to the increased content of β-endorphin in all patients after any operation needs further investigation. Further studies should determine the optimal dose when NSAIDs and opioid drugs are used together, and also explore the existence of one NSAID that has the potential to replace the traditional opioid drugs and can achieve adequate analgesia.

Randomized Controlled Trial
Magnesium sulfate accelerates the onset of low-dose rocuronium in patients undergoing laryngeal microsurgery.
We evaluated the effect of magnesium sulfate-an enhancer of neuromuscular blockade-on onset and duration of low dose of rocuronium, and on operating conditions during laryngeal microsurgery. ⋯ Magnesium sulfate 30 mg/kg accelerated the onset and improved operating conditions of low-dose rocuronium without prolongation of action.

Randomized Controlled Trial Comparative Study
Effects of the concurrent use of a reduced dose of propofol with divided supplemental remifentanil and moderate hyperventilation on duration and morphology of electroconvulsive therapy-induced electroencephalographic seizure activity: A randomized controlled trial.
The clinical adequacy of electroconvulsive therapy (ECT) depends on not only seizure duration but also seizure amplitude and postictal suppression. The objective of this study was to evaluate the effects of combination of a reduced dose of propofol and moderate hyperventilation on seizure duration and electrical stimulus requirement for adequate ictal amplitude and postictal suppression. ⋯ A reduced dose of propofol combined with divided supplemental remifentanil under moderate hyperventilation during ECT may contribute to reduced electrical dosage due to the ability of its augmentation of seizure amplitude and postictal suppression in the late phase of the ECT course.
