Objective:
Evaluation of respiratory function after 24 hours from intervention related to two different surgical techniques of cholecistectomy.
Patients And Methods:
Thirty patients submitted to cholecystectomy, nine by laparotomy and twenty-one by video-laparoscopy. The ventilatory parameters considered are as follows: CV, FCV, VEF1, FEF25-75%; and moreover also some variables of acid-base balance: pH, paCO2 e paO.
Results:
In all cases was evidenced a decrease of respiratory activity. This phenomenon was more evident in the laparotomy group (CV = 37, 35, FCV = 41, 47, VEF1 = 40, FEF25-75% = 36.62% related to preoperative values versus 71.20, 80.88, 79.29, 77.91% in the videolaparoscopic group. No significative differences were registered between the two groups as to postoperative paO2, which was moderately lower in all patients, while no variation was observed for pH and paCO2.
Conclusions:
Data collected confirm that after laparoscopic cholecystectomy the ventilatory respiratory capacity is better conserved, that clinically means lower incidence of postoperatory pulmonary complications.
