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.

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.

Observational Study
Relationship between normal preoperative white blood cell count and major adverse events after endovascular repair for abdominal aortic aneurysm: results of a pilot study.
To examine the association between preoperative white blood cell (WBC) count within the reference range and major adverse events (MAEs) following endovascular repair of abdominal aortic aneurysms (AAA). ⋯ This pilot study demonstrates a linear correlation between an increasing preoperative WBC count within the reference range and an increased risk for postoperative MAEs following endovascular repair for AAA. Identification of high-risk patients at an early stage by using WBC count could prove useful in implementing measures to improve their clinical outcome.

Bispectral index is an accepted depth of anaesthesia monitor for guiding intraoperative hypnotic agent administration. Frontalis EMG displayed on BIS monitor may increase due to twitching of frontalis muscle. ⋯ We report a case of artefactual increase of EMG and subsequently BIS values, due to electrical artefact from cranial nerve stimulator being used to identify the facial nerve. An explanation of the effect of stimulator signal on BIS EMG and BIS values has been provided.

Observational Study
Airway management for glossopexy in infants with micrognathia and obstructive breathing.
To identify airway management and tracheal intubation techniques for glossopexy in infants with preexisting airway obstruction under general anesthesia. ⋯ There are severe cases of infants with difficult mask ventilation and difficult tracheal intubation in which a fiberscope is required because video laryngoscopy fails to improve the view of the larynx.
