Randomized Controlled TrialIs video laryngoscope-assisted flexible tracheoscope intubation feasible for patients with predicted difficult airway? A prospective, randomized clinical trial.
Failed intubation may result in both increased morbidity and mortality. The combination of a video laryngoscope and a flexible tracheoscope used as a flexible video stylet may improve the success rate of securing a difficult airway. We tested the hypothesis that this combination is a feasible way to facilitate intubation in patients with a predicted difficult airway in that it will shorten intubation times and reduce the number of intubation attempts. ⋯ Flexible tracheoscope-assisted video laryngoscopic intubation is a feasible alternative to video laryngoscope only intubation in patients with predicted difficult airways. A flexible tracheoscope used in combination with video laryngoscope may also further increase the success rate of intubation in select patients with a proven difficult airway, particularly when in-line stabilization is required.

Randomized Controlled Trial Multicenter StudyHow to target temperature after cardiac arrest: insights from a randomized clinical trial.
Implementation of treatments able to improve survival and neurological recovery of cardiac arrest (CA) survivors is a major clinical challenge. More than ten years ago, two pivotal trials showed that application of therapeutic hypothermia (TH, 32-34 °C) to patients resuscitated from an out-of-hospital CA (OHCA) with an initial shockable rhythm significantly ameliorated their outcome. Since then, TH has been used also for non-shockable rhythms and for in-hospital CA to some extent, even if the quality of evidence supporting TH in such situations remained very low. ⋯ This is the largest study evaluating the effects of two different strategies of temperature management after CA. Some important concerns have been raised on the real benefit of keeping CA patients at 33 °C and major changes in clinical practice are expected. We discussed herein the main differences with previous randomized trials and tried to identify possible explanations for these findings.

Randomized Controlled Trial
The use of a nasogastric tube to facilitate nasotracheal intubation: a randomised controlled trial.
During nasotracheal intubation, the tracheal tube passes through either the upper or lower pathway in the nasal cavity, and it has been reported to be safer that the tracheal tube passes though the lower pathway, just below the inferior turbinate. We evaluated the use of a nasogastric tube as a guide to facilitate tracheal tube passage through the lower pathway, compared with the 'conventional' technique (blind insertion of the tracheal tube into the nasal cavity). ⋯ In 20 out of 30 patients (66.7%) with the nasogastric tube-guided technique, the tracheal tube passed through the lower pathway, compared with 8 out of 30 patients (26.7%) with the 'conventional' technique (p = 0.004). Use of the nasogastric tube-guided technique reduced the incidence and severity of epistaxis (p = 0.027), improved navigability (p = 0.034) and required fewer manipulations (p = 0.001) than the 'conventional' technique.

Randomized Controlled Trial Comparative StudyA randomized comparison between double-injection and targeted intracluster-injection ultrasound-guided supraclavicular brachial plexus block.
Ultrasound-guided supraclavicular block has faster onset when a targeted intracluster-injection technique is used compared with double injection.

Randomized Controlled TrialThe Effect of Single Low-Dose Dexamethasone on Blood Glucose Concentrations in the Perioperative Period: A Randomized, Placebo-Controlled Investigation in Gynecologic Surgical Patients.
The effect of single low-dose dexamethasone therapy on perioperative blood glucose concentrations has not been well characterized. In this investigation, we examined the effect of 2 commonly used doses of dexamethasone (4 and 8 mg at induction of anesthesia) on blood glucose concentrations during the first 24 hours after administration. ⋯ Because blood glucose concentrations during the first 24 hours after administration of single low-dose dexamethasone did not differ from those observed after saline administrations, these results suggest clinicians need not avoid using dexamethasone for nausea and vomiting prophylaxis out of concerns related to hyperglycemia.
