This study was carried out to compare the difference between assist(A) and controlled(C) ventilation group's blood gases during the general anesthesia. All samples were taken from the radial artery. The results were as follows, 1) Pa CO2was increased to 43. 9 5torr+/-7. 85 in group A and decreased to 28. 65 torr+/-6. 05 in group C. (p(0. 005) 2) Acidemia(7.335+/-0.51) in group A and alkalemia(7.
481+/-0.07) in group C were noticed. (p(0. 005) 3) B.E. and bicarbonate levels were within normal range in both groups.
It's necessary to choose the patterns of ventilation before anesthesia, because of the anesthesiologist were apt to give alveolar hyperventilation during the controlled ventilation manually, but mild respiratory acidosis were developed during the assist ventilation. |
