STUDY OBJECTIVE The objective of this study was to determine the effect of increasing head elevation and neck flexion on the quality of laryngeal view during laryngoscopy. METHODS Laryngoscopy with a straight blade was performed on 7 fresh human cadavers. Laryngeal views were recorded with the direct laryngoscopy video system, and the laryngoscopy angle was measured throughout the procedure w...

There is a growing body of evidence to support the use of rigid indirect laryngoscopy or 'video' laryngoscopy for tracheal intubation. We summarise some of the key issues, comparing rigid indirect laryngoscopy with direct conventional laryngoscopy.

endotrachial intubation can have serious deleterious hemodynamic changes. hypertension and tachycardia are especially dangerous in coronary artery disease, intracranial hypertension. magnesium sulfate is known for its vasodilating properties. several studies have reported favorable protective hemodynamic properties of magnesium when used as a premedicant in cardiac or elderly patients. our aim ...

background: laryngoscopy is an invasive technique that is associated with severe cardiovascular complications. this study was designed to compare the preventing effect of two doses tramadol injection on the heart rate and blood pressure changes after laryngoscopy and tracheal intubation in elective surgical patients. methods: in this clinical trial study, 189 elective surgical patients randomly...

OBJECTIVES In the critically ill undergoing urgent endotracheal intubation by direct laryngoscopy, multiple attempts are often required with a higher complication rate due to the urgency, uncontrolled setting, comorbidities, and variability in expertise of operators. We hypothesized that Glidescope video laryngoscopy would be superior to direct laryngoscopy during urgent endotracheal intubation...

conclusions the incidence and severity of sore throat and hoarseness after tracheal intubation by glide scope were lower than in the macintosh laryngoscope. the incidence and severity of sore throat were increased by intubation and longer operation times. patients and methods three hundred patients were randomly allocated into two groups of 150: macintosh blade laryngoscope or glide scope video...

BACKGROUND The incidence of difficulty with intubation in the general population depends upon the definition used but results as high as 37% have been published. Endocrine disorders such as diabetes and hyperthyroidism have been linked to an increased incidence of difficult intubation via laryngoscopy. Hypercalcemia with resulting calcification has been demonstrated to result in neck pain, decr...

INTRODUCTION AND OBJECTIVES The commonly-used predictors for difficult airway management are not very accurate. We investigate the power of indirect laryngoscopy with the rigid 70-degree laryngoscope as a predictor of difficult visualisation of the larynx with direct laryngoscopy. METHODS We performed preoperative indirect laryngoscopy with the rigid laryngoscope on 300 patients. The vision o...
