5 Clinical Trials for Various Conditions
The purpose of this study was to use Near Infrared Spectroscopy (NIRS) monitoring on participants undergoing shoulder surgery in the beach chair position (BCP) to determine cerebral desaturation events (CDE) and to further determine cognitive changes pre and post surgery using the Mini Mental State Exam.
The purpose of this study is to compare the changes measured by Somanetics Invos cerebral oximeter to the mean arterial pressure at brain level in patients having elective shoulder replacement surgery. The Somanetics Invos System measures and monitors the oxygen saturation (rS02) of blood in the brain tissues to help prevent brain injury or other complications. The investigators hypothesize that maintaining normocarbia and systemic mean arterial pressure at or above 70mmHg during general anesthesia in the beach chair position will decrease the number of cerebral deoxygenation events during the procedure.
The seated or "beach chair" position during surgery and general anesthesia decreases brain oxygen levels and can result in stroke. As such, poor neurological outcome following beach chair positioning is a growing concern. In the proposed study the investigators test the hypothesis that changes in ventilation strategy and anesthetic technique can affect cerebral oxygenation in anesthetized patients in the beach chair position.
The study compares the effect of thigh high compression stockings on cerebral desaturation events in patients undergoing shoulder arthroscopy in the beach chair position with a BMI greater than or equal to 30.
The aim of this clinical investigation is to determine the effect of intraoperative ventilation on cerebral oxygen saturation in patients undergoing arthroscopic shoulder surgery in the beach chair position (BCP)
