ABSTRACT
Objective To compare the effect of different flow rate of oxygen inhalation on relieving scapuledynia after laparoscopic cholecystectomy(LC) with carbon dioxide pneumoperitoneum. Methods 100 patients adopted LC were divided into the 2 L/min group (n=50), the 4 Ldmin group (n=50), both re-ceived oxygen inhalation 6 hours after LC. The incidence and degree of scapulodynia and the blood- gas analysis were analyzed. Results The incidence of scapulodynia after LC in the 4 L/min group was signifi-cantly lower than that of 2 L/min group. PaCO2,PaO2 and pH in the 4 L/min group were different from those of the 2 L/min group. Conclusions Increasing flow rate of oxygen inhalation can relieve incidence and degree of scapulodynia after laparoscopic cholecystectomy.
