Shoulder arthroscopy is one of the most commonly performed orthopaedic procedures and it is often done with the patient in the upright, or beach chair position (BCP).
There have been multiple reported complications associated with the BCP, including cerebral ischemia, loss of vision, ophthalmoplegia, stroke, and even death. It has been reported that patients with a body mass index (BMI) of 34 or greater are as much as 12 times more likely to experience cerebral desaturation events (CDEs) compared to non-obese patients. CDEs in the upright position are hypothesized to be partially related to reduced cardiac preload due to venous pooling in the lower extremities which is exaggerated in obese patients. This prospective observational study aims to determine if the use of compression stockings in obese patients undergoing shoulder arthroscopy in the BCP can reduce the incidence, frequency, or magnitude of CDEs experienced by the patient. We predict that compression hose will help to reduce cerebral desaturation events.

|Official Title:||The Effect of Compression Stockings on Cerebral Desaturation Events in Obese Patients Undergoing Shoulder Arthroscopy in the Beach Chair Position: an Observational Study|
|Study Start Date :||December 2013|
|Actual Primary Completion Date :||May 2014|
|Actual Study Completion Date :||May 2014|
All patients in this observational cohort study will wear compression hose during shoulder arthroscopy in the beach chair position to determine the effect of the stockings on the incidence of cerebral desaturation events during surgery.
Device: Compression Hose
Intervention in this case is placement of compression hose on patients
- Incidence of Intraoperative Cerebral Desaturation Event [ Time Frame: will be assessed intraoperatively ]The primary outcome measure will be to determine if the application of compression hose on the legs of obese patients will have an impact on the incidence of cerebral desaturation events during shoulder arthroscopy in the beach chair position.
- Length of Cerebral Desaturation Event [ Time Frame: will be assessed intraoperatively ]The length of time of each cerebral desaturation event (CDE) will be recorded for each occurrence.
