Summary

In patients undergoing gynecologic laparoscopic surgery with trendelenburg position, the disturbance of pulmonary gas exchange frequently occurs due to high intra-abdominal pressure. The investigators tried to evaluate the effect of various inspiratory to expiratory ratio on pulmonary gas exchange by randomized controlled trial.

Conditions

  • Uterine Myoma
  • Ovarian Cyst
  • Laparoscopic Gynecologic Surgery

Interventions

PROCEDURE

conventional I:E ratio

conventional I:E ratio of 1:2 is applied.

PROCEDURE

1:1 ratio

I:E ratio of 1:1 is applied.

PROCEDURE

2:1 group

Inverse I:E ratio of 2:1 is applied.

PROCEDURE

external PEEP

external positive end-expiratory pressure of 5 cmH2O is applied.
