The effect of smoking on postoperative pain and nausea, and vomiting

For this two-centre LMIC cohort study, current smoking status was not an independent predictor of early POP or PONV. Perioperative risk stratification and prevention should not solely be based on smoking status but include validated predictors (e.g., sex, history of PONV, type of procedure, duration of anaesthesia, opioid exposure). Well-powered standardised multicentre studies quantifying smoking exposure (e.g., pack-years, duration since cessation) are required.
