Four cases of ischemic injury have been reported in patients undergoing orthopedic surgery in the upright position. We hypothesized that awake patients would be able to avoid significant cerebral deoxygenation events (CDEs) compared with anesthetized patients when procedures were performed in the beach chair position. The safety of controlled hypotension for shoulder arthroscopy in the beach-chair position. MAP increases or decreases by 0. volvo wheel lock key Proponents of the beach-chair position often point to its upright, anatomic vantage point and the ease of performing an exam under anesthesia and converting to open procedures [11-13] Discussion. Near-infrared spectroscopy (NIRS) technology allows real-time measurement of cerebral oxygenation and may minimize the frequency of CDEs. A total of 80 patients over 60 years of age who had undergone arthroscopic shoulder surgery in the beach chair position were randomly allocated to either the dexmedetomidine group (Group D) or the control group (Group C)6 μg/kg/h) or a comparable amount of normal saline was infused into each group during the surgery. The upright orientation of the patient helps trainees easily identify internal and external anatomic landmarks. walmart careers in killeen tx Radiographic evaluation of the glenohumeral joint space in patients undergoing arthroscopic shoulder surgery in the beach-chair position Mario Chaves Corr ^ea, MD, MSc a,b,*, Erica Antunes Naves, MD b, Gilvan Ferreira Vaz, MD b, Thalles Abreu Machado, MD b, Marco A de Andrade, PhD c a Hospital Madre Teresa, Belo Horizonte, Brazil b Hospital Governador Israel Pinheiro, Instituto de Previd. 1 A number of advantages have been reported for the beach chair position, including ease of setup and conversion to an open approach, improvements in intra. One of the surgical procedures most commonly performed in North America is arthroscopic repair of the shoulder joint. Cerebral oxygenation (regional oxygen saturation [rSO2]) can be monitored noninvasively using near-infrared spectroscopy. Although maintaining normal Mean Arterial Pressure (MAP) is important, fluid management is also a crucial concept for hemodynamic stability. uliine The beach chair position offers the possibility to move the arm of the patient more easily and in more directions and gives a better orientation to the surgeon because of the upright position of the patient. ….
