Monitored anesthesia care (MAC) is currently the dominant method of endoscopic sedation for approximately one third of all US gastroenterologists. The popularity and success of MAC can be ascribed to many factors including increased patient turnover and improved patient satisfaction. Patients undergoing MAC maintain spontaneous breathing and routinely receive supplemental oxygen. In case of airway obstruction, additional airway adjuncts may be used such as supraglottic airway devices including oropharyngeal airway, nasopharyngeal airway, laryngeal mask, etc. A nasopharyngeal airway is a simple device that can be conveniently inserted into the supraglottic airway to secure an open passage. This is a randomized controlled trial designed to evaluate the efficacy of the routine use of nasopharyngeal airway in preventing airway obstruction during deep sedation. Patients undergoing gastrointestinal endoscopy under monitored anesthesia care using target-controlled infusion of propofol at AUBMC will be randomly and equally apportioned to the nasopharyngeal group (group A) or control group (group B). Episodes of desaturation, airway maneuvers, hemodynamic instability, adverse events related to NPA insertion, duration of the procedure, and the anesthetic dose will be recorded. The satisfaction of the anesthesiologist, gastroenterologist, and patient will be scored. The aim of this study is first to assess the efficacy of NPA in reducing respiratory events, and second, to identify the safety of this device as well as patient, gastroenterologist and anesthesiologist satisfaction.

A type of oropharyngeal airway that provides an alternative to endotracheal intubation and standard mask anesthesia in certain patients. It is introduced into the hypopharynx to form a seal around the larynx thus permitting spontaneous or positive pressure ventilation without penetration of the larynx or esophagus. It is used in place of a facemask in routine anesthesia. The advantages over standard mask anesthesia are better airway control, minimal anesthetic gas leakage, a secure airway during patient transport to the recovery area, and minimal postoperative problems.
A form of bronchial disorder with three distinct components: airway hyper-responsiveness (RESPIRATORY HYPERSENSITIVITY), airway INFLAMMATION, and intermittent AIRWAY OBSTRUCTION. It is characterized by spasmodic contraction of airway smooth muscle, WHEEZING, and dyspnea (DYSPNEA, PAROXYSMAL).
Patient care procedures performed during the operation that are ancillary to the actual surgery. It includes monitoring, fluid therapy, medication, transfusion, anesthesia, radiography, and laboratory tests.
The structural changes in the number, mass, size and/or composition of the airway tissues.
Abnormally slow pace of regaining CONSCIOUSNESS after general anesthesia (ANESTHESIA, GENERAL) usually given during surgical procedures. This condition is characterized by persistent somnolence.
An anesthesiologist (US English) or anaesthetist (British English) is a physician trained in anesthesia and perioperative medicine. Anesthesiologists are physicians who provide medical care to patients in a wide variety of (usually acute) situations. ...
