Background and purpose: Airway assessment is very important in anesthesia. The aim of this study was to determine the diagnostic value of Mallampati test indicators in supine and sitting positions with and without phonation in anesthesia candidate patients. Materials and methods: This cross-sectional descriptive study (diagnostic approach) was done in 200 adult patients ≥16 years, undergoing s...

Introduction: This study compared the extubation of patients in prone versus supine positions in patients undergoing lumbar disc surgery. Methods: In this single-blind clinical trial, 60 patients who were candidates for elective lumbar disc surgery were selected and randomly assigned into two groups of 30 patients. All patients primarily underwent surgery in the prone position. After surgery a...

Background and purpose: Since the introduction of the prone position as a therapeutic maneuver in patients with lung diseases, numerous studies conducted on both adults and children have almost uniformly reported an improvement in PaO2 in the prone compared to supine position. This study was conducted to determine the effect of body position on the arterial oxygen saturation of healthy prematur...

Background & Aims: Tracheal intubation with a cuffed tube for the administration of general anesthesia is routine. The cuff of the endotracheal tube is inflated with air to achieve an adequate seal to prevent aspiration and leakage of air and anesthetic gases. Whereas over-inflation can decrease the mucosal perfusion, leading to pressure necrosis and nerve palsies. This study aimed to evaluate ...
