5 Clinical Trials for Various Conditions
The purpose of the study conducted at VA Medical Center in Miami is to determine if smoking electronic cigarettes (known as e-cigarettes) that contain nicotine have less negative effects than regular cigarettes on the person's respiratory health. We will assess this by measuring pulmonary function tests, several body molecules and functionality of the airway cells. We will also evaluate how smokers can maintain exclusive electronic cigarettes use. In this study, some people will continue to smoke regular tobacco cigarettes while others will switch to a nicotine-containing electronic cigarette.
The purpose of this study is to compare three different standard of care methods of double-lumen endobronchial tube (DLT) placement in patients who are scheduled to have thoracic surgery in which lung isolation is required.
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 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.
This study is a randomized controlled trial comparing oxygen delivery by nasal mask with continuous positive airway pressure versus standard care (nasal cannula or standard facemask) during propofol-based sedation for gastrointestinal endoscopy procedures to reduce the incidence of hypoxia. The primary outcome will be the rate of oxygen desaturation below 90% for ≥15 seconds.
