Abstract:
Twenty-two female adults were under study by monitoring the end-tidal CO2 during laparoscopy in order to define the rate of CO2 elevation. Experimental results showed that under the intraabdominal pressure of 14.5 cm H2O (ranging from 12 to 18 cm H2O), the elevated CO2 level varied from 3 mmHg to 19 mmHg with a mean value of 8.3 +/- 3.7 mmHg (P less than 0.001). It took 10.5 +/- 1.9 min to reach peak level.
