NCT ID: NCT01936662 Completed - Airway Morbidity Clinical Trials

Endotracheal Tube Versus Laryngeal Mask Airway for Esophagogastroduodenoscopy

Start date: August 2011
Phase: N/A
Study type: Interventional

Esophagogastroduodenoscopy (EGD) is a relatively common procedure in pediatric patients undergoing evaluation for various gastrointestinal ailments. The procedure itself, with or without associated biopsies, is relatively short in length. Unlike adults, who regularly undergo this procedure with conscious sedation, children most often require general anesthesia. While safe and effective, endotracheal tracheal tube (ETT) intubation of children for EGD can result in delayed awakening and slow room turnover, particularly when intravenous medications are required for intubation. Laryngeal mask airway (LMA) is an alternative to intubation, which permits removal before full awakening. Although considered a safe alternative to tracheal intubation in appropriate cases, disadvantages of the LMA have been reported including kinking, occluding view of the surgical field, failure of placement requiring tracheal intubation, aspiration of gastric contents, desaturation, and laryngospasm. The study was designed to determine whether use of an LMA for EGD could reduce operating room time, while providing satisfactory conditions for the endoscopist, and an equivalent side effect and safety profile as compared to ETT in otherwise healthy children with gastrointestinal complaints

A New Insertion Technique for Laryngeal Mask Airway

Start date: November 2011
Phase: N/A
Study type: Interventional

A laryngeal mask airway ("LMA") is an airway device that is commonly used and placed under general anesthesia to facilitate ventilation of the patient's lungs while anesthetized. It is similar to an "endotracheal tube" (a breathing tube) but is less invasive. It is also placed as a backup when the Anesthesiologist is unable to pass a breathing tube and the patient is not adequately ventilating. Unfortunately, an LMA may lead to complications similar to those of breathing tube placement, such as sore throat and hoarse voice. Previous studies have examined several variables that may affect how often complications occur; these variables include giving anti-inflammatory medications and inflating the LMA to different pressures (the "working" end of the LMA, which rests in the patient's throat, has a cuff that is inflated to provide a seal). We are studying the effect of the PLACEMENT TECHNIQUE on postoperative sore throat, hoarse voice, and difficulty swallowing. We will be using 3 placement techniques - the traditional placement technique, a slightly different traditional placement technique, and a new technique, abbreviated the "ELLIA" method. The hypothesis of this study is that a new LMA insertion technique will have no difference in postoperative pharyngolaryngeal morbidity including sore throat, dysphagia and dysphonia.

NCT ID: NCT01371773 Completed - Clinical trials for Intubation Complication

Repositioning Method for Left-sided Double Lumen Tubes

Start date: June 2011
Phase: N/A
Study type: Interventional

The purpose of this study is to devise repositioning method of a left-sided double lumen tube into left mainstem bronchus in case of misplacement into right mainstem bronchus.

NCT ID: NCT01367678 Completed - Airway Morbidity Clinical Trials

Mucosal Pressure of the Laryngeal Mask Airway Supreme Versus the i-Gel in Paralyzed Anesthetized Female Patients

Start date: May 2011
Phase: N/A
Study type: Interventional

In the following randomized non-crossover study, the investigators test the hypothesis that directly measured mucosal pressure differ between the laryngeal mask airway (LMA) Supreme and the i-Gel in paralyzed anesthetized females. Thirty females aged 19-65 years were randomly allocated to receive either the size 4 LMA Supreme or i-Gel for airway management. Microchip sensors were attached to the LMA Supreme/i-Gel at four locations corresponding to the A, base of tongue; B, distal oropharynx; C, hypopharynx; and D, pyriform fossa. Insertion success rate and oropharyngeal leak pressure were also measured.
