Smoking Cessation Can Reduce the Incidence of Postoperative Hypoxemia After On-Pump Coronary Artery Bypass Grafting Surgery.

Abstract：

OBJECTIVES:To determine whether smoking cessation can reduce the incidence of postoperative hypoxemia (POH) after on-pump coronary artery bypass grafting (CABG) surgery. DESIGN:Prospective, single-center, observational study. SETTING:Single-center university teaching hospital. PARTICIPANTS:The study comprised 300 patients undergoing on-pump CABG surgery who met the inclusion criteria. Patients were divided into the following 3 groups according to smoking status: sustained quitters (n = 132)-smoking cessation for more than 1 month and less than 1 year; quitters (n = 95)-smoking cessation for more than 1 week and less than 1 month; and smokers (n = 73)-smoking at least 1 cigarette per day for at least 1 year. INTERVENTIONS:None. MEASUREMENTS AND MAIN RESULTS:The primary outcome was the incidence of POH after on-pump CABG surgery. Secondary outcomes included length of postoperative mechanical ventilation and intensive care unit stay between the POH group and non-POH group. There were significant decreases of POH incidence in the sustained quitters and quitters compared with the smokers both after intensive care unit (ICU) admission and 24 hours after surgery (18.2%, 18.9%, v 32.9%; p = 0.036 and 9.8%, 10.5%, v 26%; p = 0.003, respectively), and there was no significant difference in POH incidence between the sustained quitters and quitters. The length of postoperative mechanical ventilation was longer in smokers than in sustained quitters and quitters (15.9±6.1 h v 11.9±5.3 h and 13.0±5.8 h, respectively; p<0.05), but there were no significant differences in the length of ICU stay among the 3 groups (54.2±7.5 h v 55.1±7.5 h and 53.7±6.6 h, respectively; p = 0.333). CONCLUSIONS:Smoking cessation can reduce POH after on-pump CABG surgery, and it also can shorten the length of postoperative mechanical ventilation.
