“…In adult patients undergoing general anaesthesia, disruption of myocardial oxygen balance, high carbon monoxide haemoglobin levels, increased postoperative mortality secondary to respiratory complications, increased length of stay in PACU and requirements of longer anaesthetic times (AT) than in nonsmokers have been reported (27–31). These effects correlate with the degree of smoking as well as the number of cigarettes consumed per day.…”

“…Tobacco smoking is known to pose risks to adult patients who undergo general anaesthesia. These include disruption of myocardial oxygen balance, high carbon monoxide exposure leads to high carboxyhaemoglobin levels which may affect pulse oximetry, and increased postoperative mortality secondary to respiratory complications compared with nonsmokers (27–30). In addition, smokers experience increased length of stay in postanaesthesia care units (PACU), and require longer anaesthetic times (AT) than nonsmokers.…”

“…Smoking has been shown to cause an increase in the upper airways reflex sensitivity [17] and sensitivity of the carina to stimulation by a suction catheter [18]. It would be interesting to see if a further increase in the humidity of inspired gas (saturated water vapour at 37 °C amounts to 44 mg.l −1 ) would reduce adverse airway events in the smoking population.…”

The effect of humidification and smoking habit on the incidence of adverse airway events during deepening of anaesthesia with desflurane

et al. 2000

SummaryThe effect of two levels of humidification on the incidence of adverse airway events was studied in 58 adult female patients during deepening of anaesthesia using up to 12% desflurane. Humidification was provided by a breathing system filter with either low moisture-conserving performance (17.2 mg.l 21 at 0.5 l tidal volume, Group L) or high moisture-conserving performance (33.5 mg.l 21 at 0.5 l tidal volume, Group H). Forty-eight per cent of patients smoked and there were more smokers in Group L than in Group H. Adverse airway events consisted of coughing and laryngospasm. For coughing, the dominant explanator was smoking. When both humidity and age were included in the analysis, there was a significant smoking±humidity interaction (p , 0.05), such that high humidity decreased the incidence of coughing in nonsmokers but not in smokers. The incidence of laryngospasm was significantly lower in Group H than in Group L (p , 0.05). We conclude that when patients inspire high concentrations of desflurane during induction of anaesthesia, increasing humidification to the levels achieved in this study decreases the incidence of coughing among nonsmokers and of laryngospasm in both smokers and nonsmokers.

Effect of nebulised lignocaine on the quality of induction of anaesthesia in cigarette smokers

et al. 1997

SummaryWe have assessed the effect of nebulised lignocaine, given pre-operatively, upon the quality of induction of anaesthesia in cigarette smokers. Seventy-five patients were studied in a double-blind randomised fashion, receiving a nebuliser of either 4 ml 0.9% NaCl or 4 ml 4% lignocaine. All patients received a standardised anaesthetic consisting of thiopentone followed by progressive increments of enflurane. Thirty-three out of 38 patients (87%) who received nebulised lignocaine had induction without adverse events, compared with 25 out of 37 patients (68%) in the nebulised saline group (Chi-squared test p < 0.05). We conclude that the use of nebulised lignocaine, administered pre-operatively, improves the quality of induction of anaesthesia in cigarette smokers.
