Abstract

 


We compared the changes in ventilation parameters during anaesthesia and recovery room in chronic smokers and non smokers (15 chronic smokers and 15 non smokers). All patients were nomal clinically and paraclinically. The induction of anaesthesia was provided by 7 mg/kg Na thiopenthal and 0.8 mg/kg atracrium. Anaesthesia maintained 40% O2, 60% N2O and 1-1.5% isoflurane. ETCO2 (end tidal CO2) and SaO2 were measured for every 5 minutes during the operation. Hypoxia and avakening scores were measured in the recovery room. The only difference that observed between two group was SaO2 at the time of extubation and this result was statistically insignificant. A 13% decrease in ETCO2 was observed in chronic smokers. Chronic smokers avakened later than non smokers, and their secretions were also more than non smokers. Non smokers did not cough at the recovery room but chronic smokes coughed at a percentage of 20%. Morbidity was 41% in the chronic smokers group. We concluded that smoking must be avoided for the chronic smokers at least a few days before operation. [Journal of Turgut Ozal Medical Center 1997;4(4):413-417]
