Preoperative smoking status was not observed to be associated with postoperative mortality , cardiovascular complications , bleedings , anastomotic leakage , or allograft rejection .
CONCLUSIONS Preoperative smoking was found to be associated with an increased risk of the following postoperative complications : general morbidity , wound complications , general infections , pulmonary complications , neurological complications , and admission to the intensive care unit
OBJECTIVE To systematic ally review and summarize the evidence of an association between preoperative smoking status and postoperative complications elaborated on complication type .
BACKGROUND The conclusions of studies examining the association between preoperative smoking and postoperative complications are inconsistent , thus there is a need for a review and meta- analysis to summarize the existing evidence .
Preoperative smoking habits and postoperative pulmonary complications.
OBJECTIVE To examine the effect of preoperative smoking behavior on postoperative pulmonary complications . DESIGN Prospect i ve cohort study . SETTING The Veterans Administration Medical Center , Syracuse , NY . PARTICIPANTS Patients scheduled for noncardiac elective surgery ( n=410 ) . MEASUREMENTS AND RESULTS  Smoking status  was determined by self-report . Postoperative pulmonary complications were determined by systematic extraction of medical record data . Postoperative pulmonary complications occurred in 31 of 141 ( 22.0 % ) current smokers , 24 of 187 ( 12.8 % ) past smokers , and 4 of 82 ( 4.9 % ) never smokers . The odds ratio ( OR ) for developing a postoperative pulmonary complication for current smokers vs never smokers was 5.5 ( 95 % confidence interval [ CI ] , 1.9 to 16.2 ) and 4.2 ( 95 % CI , 1.2 to 14.8 ) after adjustment for type of surgery , type of anesthesia , abnormal chest radiograph , chronic cough , history of pulmonary disease , history of cardiac disease , history of COPD , education level , pulmonary function , body mass index , and age . Current smokers who reported reducing cigarette consumption  prior to surgery were more likely to develop a complication compared with those who did not ( adjusted OR=6.7 , 95 % CI , 2.6 to 17.1 ) . CONCLUSIONS Current smoking was associated with a nearly sixfold increase in risk for a postoperative pulmonary complication . Reduction in smoking within 1 month of surgery was not associated with a decreased risk of postoperative pulmonary complications
