Clinical Indicators of the Need for Telemetry Postoperative Monitoring in Patients With Suspected Obstructive Sleep Apnea Undergoing Total Knee Arthroplasty

This study used the STOP-Bang questionnaire to diagnose patients with possible obstructive sleep apnea (score ≥3). We hypothesized that a STOP-Bang score of 3 or greater would significantly correlate with the number of oxygen desaturation episodes during the first 48 hours after total knee arthroscopy. Methods The STOP-Bang questionnaire was administered to 110 patients preoperatively. All patients underwent spinal-epidural anesthesia with a saphenous nerve block and sedation and were connected to the Nellcor OxiMax N-600x pulse oximeter for 48 hours postoperatively. Results Final analysis included 98 patients. There was no significant difference in the total number of desaturation events between STOP-Bang groups (score
