purpose: to compare success rates of external dacryocystorhinostomy (dcr) with and without bicanalicular silicone intubation for management of primary acquired nasolacrimal duct obstruction. methods: in a randomized clinical trial study, 52 patients with primary acquired nasolacrimal duct obstruction underwent external dcr. patients were randomly enrolled into two groups. in the 1st group, exte...

INTRODUCTION Patients with mandible deformity may die, as a result of airway management failures. The awake nasal fiberoptic intubation is known as the optimum intubation method, in the mentioned patients, although, in several cases, fiberoptic intubation fails. CASE PRESENTATION The present case discusses a patient with severe deformity of mandible that was admitted for correction with free-...

BACKGROUND Many studies have shown Airtraq videolaryngoscope provided faster tracheal intubation and a higher success rate than other videolaryngoscopes. Recently, different types of videolaryngoscopes have been reported for use in double-lumen tube (DLT) intubation. However, the advantages and disadvantages between them remain undetermined for DLT intubation. In this study, we compared the Air...

BACKGROUND Immobilization of the cervical spine worsens tracheal intubation conditions. Various intubation devices have been tested in this setting. Their relative usefulness remains unclear. METHODS We searched MEDLINE, EMBASE, and the Cochrane Library for randomized controlled trials comparing any intubation device with the Macintosh laryngoscope in human subjects with cervical spine immobi...

Background: Training of airway management and tracheal intubation skill in emergencies for resuscitation of patients are basic skills for medical students. However, the success rate of beginners in this skill is low. Video laryngoscopes are new devices that can increase the success of endotracheal intubation training. Methods: This clinical trial was conducted with 30 medical students who came...

BACKGROUND Although Lightwand and Glidescope have both shown high success rates for intubation, there has been no confirmation as to which device is most effective for difficult endotracheal intubation. We compared the Glidescope and Lightwand devices in terms of duration of intubation and success rate at the first attempt in a simulated difficult airway situation. METHODS Fifty-eight patient...

BACKGROUND Cricoid pressure (CP) is applied during induction of anesthesia to prevent regurgitation of gastric content and pulmonary aspiration. However, it has been suggested that CP makes tracheal intubation more difficult. This double-blind randomized study evaluated the effect of CP on orotracheal intubation by direct laryngoscopy in adults. METHODS Seven hundred adult patients undergoing...

BACKGROUND During McGrath videolaryngoscope (VL) intubation, a styletted endotracheal tube maintaining an upward distal tip angle is recommended by some manufacturers. However, a styletted endotracheal tube can elicit rare but potentially serious complications. The purpose of this study was to demonstrate that a nonstyletted tube with exaggerated curvature would be noninferior to a styletted tu...

awake intubation is the choice for airway management in anticipated difficult airway (da), which means establishing airway without induction of deep sedation; however, in cases where sedation is precarious, decision in emergency situations, success in awake intubation is dependent on proper regional airway block. a 21 year old man with bilateral temporo-mandibular ankyolosis and a 25 years old ...
