[Simultaneously monitoring end tidal CO2 and other parameters versus anesthesia management].

OBJECTIVE

To investigate the significance of end tidal CO2(ETCO2) combined with other techniques in anesthesia management.

METHODS

Twenty two patients undergoing general anesthesia were monitored with electromyocardiogram (ECG), invasive arterial blood pressure (IABP), plethysmogram and capnography simultaneously. Ten patients undergoing epidural anesthesia and cervical plexus block were monitored with ETCO2.

RESULTS

During general anesthesia the depth of general anesthesia, status of ventilation and the degree of muscle relaxation could be grossly evaluated by simultaneously monitoring ETCO2, capnography, plethysmogram, ECG and IABP. ETCO2 could also provide an objective standard for the assessment of respiratory function during spontaneous ventilation.

CONCLUSIONS

ETCO2 combined with other monitoring techniques can increase the safety of anesthesia and the accuracy of anesthesia management.
