[Effect of P(ET)CO(2) monitoring on cardiac function during hepatectomy].
OBJECTIVE
To investigate the relationship between end-tidal Pco2 (P(ET)CO(2)) and cardiac output (CO) during hepatectomy.


METHODS
Swan-Ganz catheter was inserted into the right jugular vein of twenty-one patients undergoing hepatectomy to observe the hemodynamic parameters. Cardiac output (CO) was examined by thermodilution technique. Mechanical ventilation was performed after anaesthesia induction, and P(ET) CO(2) was monitored continuously. The relationship between CO and P(ET)CO(2) was analyzed.


RESULTS
A strong positive correlation was found between P(ET)CO(2) and CO, r =0.90, P < 0.05.


CONCLUSIONS
P(ET)CO(2) can be used as a predictor of CO. This technique is safe, simple and can be used in hemodynamic unstable patients during the major surgical procedure and in patient with poor cardiac function.
