不同循环加压冷疗时间对缓解膝关节镜患者术后疼痛和肿胀的效果观察

Effect of cryo/cuff system at different durations on postoperative swelling and pain in patients with knee arthroscopy

目的探讨不同治疗时间循环加压冷疗对缓解膝关节镜患者术后疼痛和肿胀的效果观察。方法将行膝关节镜手术92例患者分为试验组31例、对照组31例和空白组30例,试验组术后24h内每间隔8h行30min的循环加压冷疗1次;对照组术后48h内每间隔8h行30min的循环加压冷疗1次;空白组不使用任何形式的加压冷疗,术后只进行常规护理。术后24h和48h,采用视觉模拟评分法(visualan alogue scalescore,VAS)对患者进行疼痛评估,肿胀情况用患侧、健侧肢体大腿周径的差值来评估。结果试验组和对照组术后疼痛程度和肿胀情况均低于空白组(P<0.05或P<0.001),试验组和对照组术后疼痛与肿胀情况比较,差异无统计学意义(均P>0.05)。结论膝关节镜术后24h内进行间断加压冷疗可减轻患肢疼痛,缓解肿胀情况,并可缩短卧床时间,有利于患者尽早下地活动,促进康复。

Objective To explore the effect of cryo/cuff system at different durations on postoperative swelling and pain in patients with knee arthroscopy.Methods Ninety-two patients having undergone knee arthroscopy were divided into 3 groups： the study group（n=31）,the control group（n=31）and the blank control group（n=30）.The study group were managed with circulating cold compress therapy for 30 mins once every 8 hours 24 hours after operation,the control group with circulating cold compress therapy for 30 mins once every 8 hours 48 hours after operation and the blank control group with routine nursing.The degree of pains was assessed using visual analogue scale and the level of swelling using the difference in the shank circle between the diseased and healthy limbs.Results The study group and control group were both better than the blank group in swelling and pain control（P 0.05）. The study group showed no difference in postoperative pains and swelling than the control group（P0.05）.Conclusion Postoperative knee arthroscopy,using cryo/cuff system can alleviate pains and swelling of joints,which is conducive for the early ambulation and promoted rehabilitation.
