Abstract
Objective: In this study, we aimed to research whether there is significant difference in the incidence of cardiovascular and respiratory complications during intraoperative and postoperative periods and the duration of recovery in patients who exposed passively to tobacco smoke compared with unexposed patients. Methods: 250 adult patients ranging in age from 18 to 60 years with the ASA I or II score who received general anesthesia for various elective surgical operations were selected and divided into two groups. Group 1(study group) included 130 patients who were exposed to passive cigarette smoke, Group 2 (control group) include 120 patients who were not exposed to smoke. Respiratory and cardiovascular complications evaluated and recorded in intraoperative and postoperative period. At the end of the operation, patients taken to the postoperative care unit (PACU) and monitored until Modified Aldrete's Score became 9 or more and stay time in PACU was recorded. Results: There was no statistically significant difference concerning demographic data and ASA status between the two groups. Among respiratory complication in the two groups there was no significant difference regarding to bronchospasm, hypoxia, laryngeal spasm. In contrary there was significant increase in the incidence of cough and hyper secretion in passive smokers. Regarding cardiovascular complications there was no significant difference between the two groups in arrhythmias or ischemia occurrence. In contrary there was significant increase in the incidence of hypertension occurrence in passive smoking group. PACU stay time in the passive smoking group was not significantly longer than control group. Conclusion: Passive smoking is associated with higher incidence of perioperative cardiovascular and respiratory complication with no prolongation of PACU stay time.
