Filter by:The delicate structures of the larynx can be compromised by innumerable causes, one of these is represented by endotracheal intubation. More frequently, these damages are represented by hematomas, edema and granulomas of the vocal cords. The pathophysiology of laryngeal damage can be explained by an ischemic attack of the chordal mucosa. Numerous risk factors can cause the onset of damage, some depending on the practice itself, such as size and type of endotracheal tube, cuff pressure, use of mandrels and / or inserting devices, use of oral or nasogastric tubes, use of neuromuscular inhibitors or sleep-inducing drugs and the duration of the intervention; others from patient-related factors, such as gender, weight, history of exposure of smoking habit, or a history of gastroesophageal reflux (GERD). The incidence of such symptoms varies from 0% to 18% among the general population, with an average of 6% with resolution of most of the symptoms within 72 hours unless substantial damage has occurred to the vocal cords or to the arytenoids. In general, the incidence of such laryngeal complications has been described by several studies, but there is no standardized protocol for measuring and evaluating their entity. The purpose of this study is to determine how the voice and the chordal clinical aspect vary after oro-tracheal intubation, evaluated through voice analysis and laryngostroboscopy.
Endotracheal intubation increased the heart rate and blood pressure in normal patients. Open heart surgery patients are more prone to hemodynamic variability. In addition, they have increased possibility for difficult intubation The heart rate and blood pressure increase impaired the oxygen consumption. This was previously shown that Videolaryngoscopes minimaly effects the vital signs in normal patients. Videolaryngoscopy inreased the rate of success in normal and difficult airway. This study aimed to compare two laryngoscopes regarding hemodynamic parameters and intubation times in coronary bypass surgery.

This study compares the distance from the operating table to the eye of the laryngoscopist while intubating the trachea with or without a shoulder roll. A photo of the glottic opening will compare the glottic views in both positions.
Many intrathoracic procedures demand optimal collapse of the operative lung to facilitate surgical exposure. Single-lung ventilation can be achieved using a double-lumen tube (DLT), a Univent tube, or an independent bronchial blocker. Insertion of a DLT using a direct laryngoscope can be more difficult than that of single-lumen tube (SLT), especially in patients for whom airway difficulty is anticipated. The safest of the proposed methods involves the placement of an SLT with the aid of an fibreoptic bronchoscope (FOB), following which the SLT is replaced with a DLT using an airway exchange technique in these patients. HumanBroncho® (Insung Medical, Seoul, Korea) is a new silicone DLT with a soft, flexible, non-bevelled, wire-reinforced tip. The oval shape, obtuse angle, and short lateral internal diameter of the bronchial lumen and its flexibility may allow for advancement to the trachea over the FOB with as much as ease as a standard SLT. In the present study, the investigators aimed to test the hypothesis that the HumanBroncho® DLT would be non-inferior to a standard SLT with regard to intubation time over an FOB in patients with semi-rigid neck collar simulating difficult airway.
The goal of this prospective randomized controlled study is to investigate the effect of head tilting on tracheal tube passing during nasotracheal intubation. The question which the investigators are trying to answer is: If patient's neck is extented on inserting tracheal tube via nostril, will the E-tube be more easily to pass through nasopharynx to oropharynx without trapping?
To investigate which shapes of stylet, hand techniques and possible condition that improve intubation successful rate and reduce the elapsed intubation time.
This study evaluates the efficiency of the rigid tube for laryngoscopy for tracheal intubation in patients with presumed difficult airway and compare the classical laryngoscopy and this method in matter of glottis visualisation and tracheal intubation.
Pneumaglide is a device designed to facilitate intubation. Patients who are undergoing a surgical procedure under general anesthesia and will require placement of endotracheal tube will be screened and upon fulfilling the inclusion criteria will be randomized to PneumaGlide group or non-PneumaGlide group. After induction of anesthesia PneumaGlide device will placed in the mouth of the Pneumaglide assigned subject. The time for intubation will be measured from the time that the laryngoscope is inserted into the mouth until the trachea is successfully intubated and compared between the groups. Oxygen saturation drop below 90% and also gastric secretion spillage will be compared between two groups as well.
