Filter by:The purpose of this study is to identify patient and provider-chosen factors that put patients at risk for the development of hypoxemia (oxygen saturation < 90% for 5 seconds) during endoscopy and to use this knowledge to develop a treatment protocol for specific causes of hypoxemia in adult esophagogastroduodenoscopy outpatients.
To describe respiratory and laryngeal responses to laryngeal stimulation during propofol anesthesia in children. To determine whether the co-administration of lidocaine blunts these reflex responses. The outcome of primary interest is the reflex laryngospasm. Hypotheses: I: The severity of laryngospasm evoked by laryngeal stimulation is reduced 2 min. after iv. administration on 2mg/kg lidocaine in pediatric patients anesthetized with propofol (3mcg/ml). II:The incidence of laryngospasm elicited by controlled stimulation 10min. after iv. administration of lidocaine is equivalent to the response before the administration of lidocaine.
The purpose of this study is to determine whether exchange of the double lumen tube before emergence with a laryngeal mask airway (Proseal) or a tracheal tube will reduce cough at emergence.
