目的探讨脑卒中后偏瘫患者有效的良肢位变换体位间隔时间。方法随机选取天津市环湖医院70例脑卒中后软瘫期患者,随机分为干预组(40例)和对照组(30例)。两组患者常规干预相同,对照组执行常规良肢位护理,干预组于入院5 d后逐步延长良肢位摆放时间,间隔时间每天递增0.5 h,最长延至4 h。分别于入院和出院2个时间点行肌力和肌张力评定,并统计干预组患者有效变换体位时间间隔。结果干预组患者平均变换体位时间为(3.16±0.40)h,单样本统计学分析具有统计学意义(P<0.01);两组患者入院和出院前肌力、肌张力评分差异均无统计学意义(P>0.05)。结论延长良肢位摆放持续时间的方法安全可行,不会降低治疗效果,软瘫期患者可延长至3 h变换体位而不发生压疮。
Objective To investigate the effective interval between limb changes in post-stroke hemiplegia patients. Methods Totally 70 patients with post-stroke soft palsy in Huanhu Lake Hospital of Tianjin were randomly divided into intervention group (40 cases) and control group (30 cases). The two groups of patients with the same routine intervention, the control group performed routine limb care, intervention group 5 days after admission to gradually extend the limb placement, interval time increased 0.5 h per day, the longest extension to 4 h. Muscle and muscle tension were assessed at admission and discharge at 2 time points, and the interval of effective body position changes was calculated in the intervention group. Results The mean change of body position in the intervention group was (3.16 ± 0.40) h, with statistical significance in single sample (P <0.01). There was no significant difference in strength and muscle tone between the two groups (P> 0.05). Conclusion The method of prolonging limb placement duration is safe and feasible, and will not reduce the treatment effect. The patients with soft palsy can be extended to 3 h to change position without pressure sore.
