Background: Modified Mallampati test is a standard method of assessing the airway for predicting potentially difficult laryngoscopy and intubation. This test requires the patient to be in sitting position for airway evaluation. Although applicable to the majority of patients, airway evaluation in sitting position may not always be convenient or advisable. Objectives: To compare modified Mallamp...

We studied prospectively 800 paediatric patients undergoing repair of cleft lip and palate to determine the predictors of difficult laryngoscopy. The incidence of difficult laryngoscopy (Cormack and Lehane grade III and IV) was 2.95% in patients with unilateral cleft lip, 45.76% in bilateral cleft lip and 34.61% in patients with retrognathia. Tracheal intubation was successful in 99% of patient...

We hypothesized that the McGRATH MAC would decrease the time of intubation compared to C-MAC for novices. Thirty-nine medical students who had used the Macintosh blade to intubate a manikin fewer than 3 times were recruited. The participants performed sequential intubations on the manikin in two simulated settings that included a normal airway and a difficult airway (tongue edema). The intubati...

BACKGROUND Video-laryngoscopes have gained popularity in the recent years and have shown definite advantages over the conventional Macintosh direct laryngoscopes. However, there is still insufficient evidence comparing the C-MAC with the Macintosh for patients during manual inline stabilization (MILS). METHODS This prospective, randomized, single blind study was carried out to compare trachea...

BACKGROUND Unpredicted Difficult Tracheal Intubation (DTI) with Macintosh occurs frequently in obese patients. We investigated the incidence of DTI using an algorithm based on preoperative assessment with the El-Ganzouri Risk Index (EGRI) and Glidescope® routine use. METHODS We prospectively enrolled morbidly obese patients undergoing abdominal surgery. Patients were scheduled for Glidescope®...

The laryngoscope should displace oral soft tissues forward out of the operator's vision. Therefore, the space in front of the view may be critical for determining the laryngoscopic view. The aim was to investigate the difference in the previsional space during difficult versus easy laryngoscopy (EL).Under general anesthesia, digital photographs of the lateral view of the head and neck were take...
