目的观察吸氧对减轻Lc术后肩部疼痛发生的影响效果。方法随机选取我院2010~2015年单纯性胆囊结石行Lc手术的患者共420例随机分为两组为常规组和干预组，常规组术后吸氧4 h 2 L/min；干预组吸氧4 L/min吸氧6~8 h，并鼓励患者早期下床活动。对两组患者进行疼痛评分观察效果。结果试验组疼痛的发生率显著降低，并且肩部疼痛程度明显轻于常规组有统计学意义（<0.05）。结论 LC术后提高并加大吸氧流量可以有效降低肩部疼痛的发生。“,”Objective To observe the effect of oxygen inhalation on reducing the incidence of postoperative shoulder pain in patients with Lc. Methods Randomly selected in our hospital 2010~2015 years simple LC surgery of cholecystolithiasis patients with a total of 420 patients were randomized to two groups as the intervention group and routine group, group received routine postoperative oxygen four hours 2 L/min;intervention group oxygen 4 L/min oxygen 6~8 hours, and to encourage early ambulation of patients. Pain score of two groups of patients was observed. Results the incidence of pain in the experimental group was significantly lower, and the pain of the shoulder was significantly less than that of the conventional group ( <0.05). Conclusion The incidence of shoulder pain can be effectively reduced by increasing and increasing oxygen flow after LC operation.
