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 .
Effect of propofol and sevoflurane on coughing in smokers and non-smokers awakening from general anaesthesia at the end of a cervical spine surgery.
BACKGROUND Coughing during emergence from general anaesthesia may be detrimental , particularly after cervical spine surgery . We compared the effect of propofol or sevoflurane anaesthesia on the incidence and severity of coughing during recovery in patients undergoing cervical spine surgery via an anterior approach . As a secondary aim , we also evaluated the influences of smoking and estimated residual anaesthetic agent concentrations on coughing . METHODS Thirty-four patients were enrolled in a r and omized prospect i ve , double-blind study to receive either propofol ( PPF ) or sevoflurane ( SEVO ) for maintenance of anaesthesia . The decision to perform tracheal extubation was based on specified criteria , including resumption of spontaneous respiration and consciousness . During emergence from anaesthesia and extubation , coughing was observed and grade d at predefined times . RESULTS The incidence of severe coughing was higher in the SEVO group than in the PPF group ( 59 % and 6 % , respectively ) , and also in smokers than in non-smokers ( 50 % and 17 % , respectively ) . The peak incidence of coughing was at tracheal extubation . The probability of coughing was influenced by the estimated residual concentration of anaesthetic agents at extubation , except for smokers in the SEVO group who were at the highest risk of coughing . CONCLUSIONS The incidence of coughing after cervical spine surgery when tracheal extubation is performed according to clinical criteria is lower after propofol anaesthesia compared with sevoflurane anaesthesia . Smokers are at increased risk of coughing , independently of the type of anaesthesia maintenance . Higher residual concentrations of anaesthetic agents decrease the probability of coughing , except for smokers anaesthetized with sevoflurane
