BACKGROUND The mechanism underlying nocturnal sudden death in patients with MSA remains unclear. It may be explained by upper airway obstruction, such as vocal cord abductor paralysis; an impairment of the respiratory center, such as Cheyne-Stokes respiration; or an impaired hypoxemic ventilatory response. OBJECTIVE To investigate the mechanism of sleep-disordered breathing in multiple system...
UNLABELLED BACKGROUND Videolaryngoscopy presents a new approach for the management of the difficult and rescue airway. There is little available evidence to compare the performance features of these devices in true difficult laryngoscopy. METHODS A prospective randomized crossover study was performed comparing the performance features of the Macintosh Laryngoscope, Glidescope, Storz CMAC a...
Aim: To compare the safety and efficacy of lidocaine and esmolol, in modifying the hemodynamic response to laryngoscopy and intubation. Design: Randomized, placebo-controlled, double-blind study was carried out in Fauji Foundation hospital Lahore from 1 st June 2012 to 31 st August 2012,after taking written informed consent from patients and permission from medical and ethical committee of hosp...
BACKGROUND Exercise-induced laryngeal obstruction (EILO) may affect as many as 6% of the adolescent population, with some patients experiencing symptoms refractory to conservative interventions. OBJECTIVES This report describes therapeutic laryngoscopy during exercise, a novel, non-surgical intervention that harnesses real-time laryngoscopy video as biofeedback to control laryngeal aperture d...
Neonatal laryngoscopy and endotracheal intubation often are required for prematurely born, low birthweight children. Previous studies have shown that these procedures are associated with a high prevalence of enamel hypoplasia of the maxillary anterior teeth. The present case report, which describes dilaceration of a left maxillary primary central incisor probably resulting from laryngoscopy, st...
BACKGROUND The Bonfils intubation fibrescope (BIF), a rigid, straight and reusable fibreoptic device, is being used increasingly to facilitate endotracheal intubation after direct laryngoscopy has failed. We tested the hypothesis that, with the BIF compared to direct laryngoscopy, the rate of failed endotracheal intubation could be reduced in patients with a difficult airway, simulated by means...
BACKGROUND The ability of good glottis visualization during direct laryngoscopy is major determinant of easy tracheal intubation. Sniffing position for laryngoscopy is considered as gold standard and ideal position. Several studies have questioned the validation of sniffing potion. OBJECTIVES This study aims to compare relative efficacy of sniffing position and simple head extension for visua...
Despite the lack of uniformity and the need of further investigation, video laryngoscopy continues to gain popularity both inside and outside the operating room. It has quickly become a first line strategy for potential and/or encountered difficult intubation. It is well established that video laryngoscope improves laryngeal view as compared with direct laryngoscopy in patients with suspected d...
BACKGROUND We explored whether positioning patients in a 25° back-up sniffing position improved glottic views and ease of intubation. METHODS In the first part of the study, patients were intubated in the standard supine sniffing position. In the second part, the back of the operating table was raised 25° from the horizontal by flexion of the torso at the hips while maintaining the sniffing p...
BACKGROUND Gaining proficiency with various airway management tools is an important goal for anesthesiology training. Indirect video laryngoscopes facilitate tracheal intubation in adults, but it is not clear whether these findings translate to children. This study evaluates the total time to successful intubation when performed by anesthesiology trainees using GlideScope Cobalt® video laryngos...
