Background:
@EN The pneumoperitoneum created byCO2 insufflation during laparoscopic cholecystectomy has several potential hemodynamic and respiratory consequences.
The purpose of this study is to investigate the effects of augmented minute ventilation on cardiovascular and ventilatory changes and to prevent hypercarbia due to CO2 insufflation during laparoscopic cholecystectomy.
@ES Methods:
@EN Thirty-six patients were divided into three groups according to the level of minute ventilation. The three groups were: control group C(minute ventilation 100ml/kg, respiratory rate 12 per minute), group R(MV 150ml/kg, RR is 18 per
minute)
and group V (MV 150ml/kg,tidal volume is 1.5 times as much as group C).
We repeatedly measured mean arterial pressure
