不同吸氧流量对改善二氧化碳气腹腹腔镜胆囊切除术后肩部疼痛效果的比较

目的 比较不同吸氧流量对改善二氧化碳气腹腹腔镜胆囊切除术(LC)后肩部疼痛的效果.方法 100例LC患者,随机分为2 L/min组(n=50),4 L/min组(n=50),在LC后持续吸氧6 h.检测2组间LC术后30 min和6 h的血气指标并观察2组间LC术后肩部疼痛发生率和疼痛程度.结果 4 L/min组肩部疼痛发生率明显降低;血气分析指标的比较,4 L/min组手术后PaCO2、PaO2、pH等血气指标较2 L/min组均有差异.结论 提高吸氧流量能降低LC术后肩部疼痛的发生率,改善LC术后肩部疼痛程度.

Effect comparison of different flow rate of oxygen inhalation on relieving scapulodynia after laparoscopic cholecystectomy with carbon dioxide pneumoperitoneum

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.
