NEW ORLEANS — Results from a randomized, blinded study presented here showed use of near-infrared spectroscopy during arthroscopic shoulder surgery with the patient in the beach-chair position did not provide a better reflection of cerebral oxygenation.
, MD, and colleagues randomly assigned 41 patients undergoing arthroscopic shoulder surgery in the beach-chair position. Anesthesiologists were either aware or unaware of near-infrared spectroscopy data. Researchers recorded the number of cerebral desaturation events and hypotensive events that required treatment throughout the surgical procedure. Cognitive function was assessed preoperatively, immediately postoperatively and at 2-weeks and 6-weeks postoperatively using the Montreal Cognitive Assessment score.
