BACKGROUND Obstructive sleep apnea (OSA) is an independent risk factor to develop perioperative complications during weight loss surgery, but the mechanisms are unclear. It is possible, that patients with OSA have a higher incidence of desaturation during induction of anesthesia. METHODS We enrolled 100 morbidly obese (body mass index: 53+/-10) adult patients undergoing open bariatric surgery...

OBJECTIVES We wanted to evaluate whether the presence of nasal obstruction makes a change on the association between the modified Mallampati score and the severity of sleep-disordered breathing (SDB) and the sleep quality. METHODS Polysomnography (PSG), the modified Mallampati score (MMS), the body-mass index, and a questionnaire about nasal obstruction were acquired from 275 suspected SDB pa...

BACKGROUND During the course of their training, medical students may receive introductory experience with advanced resuscitation skills. Endotracheal intubation (ETI--the insertion of a breathing tube into the trachea) is an example of an important advanced resuscitation intervention. Only limited data characterize clinical ETI skill acquisition by medical students. We sought to characterize me...

Copyright c Korean Society of Anesthesiologists, 2009 Background: Unanticipated difficulties during tracheal intubation are related to perioperative morbidity and mortality, but the success of direct laryngoscopic intubation depends largely on clinician’s experience and the upper airway anatomy. The lightwand was introduced as alternative intubation technique, but the indicators of difficult li...

Objective: To compare hemodynamic changes (systolic blood pressure and pulse) after intubation with Macintosh McCoy laryngoscopes.
 Study Design: Randomised control trial (Clinicaltrials.gov: NCT05133375)
 Place Duration of Study: Combined Military Hospital, Jhelum Pakistan, from Apr to Oct 2021.
 Methodology: A group 272 patients reporting the operation theatre were selected div...

OBJECTIVE To identify compliance with the procedures for securing the airway of patients submitted to anesthesia, defined as highly recommended in the World Health Organization Surgical Safety Checklist. METHODS A prospective, cross-sectional, observational study was conducted with 87 patients aged 18 to 60 years, classified as ASA grade 1 or 2 according to the American Society of Anesthesiol...

BACKGROUND There are few national figures on the incidence of failed tracheal intubation during general anaesthesia in obstetrics. Recent small studies have quoted a rate of one in 250 general anaesthetics (GAs). The aim of this UK national study was to estimate this rate and identify factors that may be predictors. METHODS Using the UK Obstetric Surveillance System (UKOSS) of data collection...

BACKGROUND This study was performed to assess whether intubation is more difficult in obese patients and to assess the ability of a new index: the ratio of the neck circumference to thyromental distance (NC/TM), to predict difficult intubation in obese patients. METHODS The incidence of difficult tracheal intubation in 123 obese (BMI≥27.5 kg m(-2)) and 125 non-obese patients was compared. Dif...
