Obstructive Sleep Apnea and Postoperative Hyperalgesia in Bariatric Surgery: A Prospective Observational Cohort Study

Our study found that patients with high risk of moderate to severe OSA were more likely to have postoperative hyperalgesia than those in the low-risk group, and the hyperalgesia was more severe in patients with high risk of moderate to severe OSA within 24 hours after surgery. These results highlight the need for OSA screening in preoperative assessments to mitigate postoperative hyperalgesia.
