Abstract:
We studied the effects of intraperitoneal CO2 insufflation on the blood pressure, acid-base balance and blood gas changes by continuous recording of blood pressure, heart rate and repeated determinations of blood pH and blood gas. This was done by direct method in various conditions such as the horizontal position without CO2 insufflation, lithotomy and Trendeledburg positions with CO2 insufflation and the horizontal position after deflation in 20 women having had laparoscopies. The following data are the experimental results. 1) Laparoscopy in 20 women with intraperitoneal CO2 insufflation of up to 10~15 mmHg in the lithotomy and Trendelenburg positions under controlled ventilation was sccompanied with elevated arterial pressure, increased heart rate, increased PCO2, and a decrease in blood pH. 2) When the abdomen was completely deflated and the patient was placed in horizontal position under controlled ventilation, all recordings returned close to the original control values. 3) The present study represented the remarkable stability of the cardiovascular system, acid-base balance and blood gases with the aid of controlled ventilation during CO2 pneumoperitoneum.
