Methods:25 ASA Ⅰ~Ⅱpatients, undergoing elective abdominal surgery , D-lite transmitter were used and PetCO2 were monitored after induction and intubation . Arterial blood samples were taken from arteria dorsalis pedis , and PetCO2 were recorded after 30 minutes mechanical ventilation. Results:PetCO2 correlated positively with arterial partial pressure of carbon dioxide (PaCO2), r=0.399, P<0.05. Deep symbol on PetCO2 wave platform could be seen when spontaneous respiration recovery beginning in 19 patients. Tidal volume of mechanical ventilation were reduced according to blood gas results in 17 patients. Conclusions:We examined PetCO2 correlated positively with PaCO2. When PetCO2 monitor were used, acid -base imbalance, calx natrica ineffective and hyperventilation could be found in time. We think PetCO2 monitor should be used routinely in general anesthesia. Key words:Partial pressure of end-tidal carbon dioxide; Monitoring; General anesthesia. Corresponding author:Yi-sa Shi, MD; huanghe365@sohu.com |
