STOP-Bang–Defined Obstructive Sleep Apnea Risk and Postoperative Nausea and Vomiting in Laparoscopic Surgery Patients: A Prospective Cohort Study

STOP-Bang-defined OSA risk has a significant association with PONV in laparoscopic surgery patients. Female gender and younger age increased susceptibility to PONV, whereas OSA risk was augmented in older people. These results illustrate the clinical utility of integrating STOP-Bang screening into preoperative evaluation to optimise perioperative care and individualise preventive measures against PONV. These findings support integrating STOP-Bang screening into preoperative risk assessment to improve postoperative outcomes.
