目的 探索空气波压力治疗在预防透析相关肌肉痉挛中的作用。 方法 将绍兴第二医院血液净化中心研究实施前监测期间1月内发生3次及以上透析相关肌肉痉挛的患者共47例，分为观察组(24例)和对照组(23例)，对照组采用常规血液透析，观察组在血液透析同时辅以空气波压力治疗，比较2组患者透析中肌肉痉挛和低血压发生情况。 结果 观察组透析相关肌肉痉挛发生率(χ2=12.797,P＜0.001)、平均改良Ashworth评分(t=-4.006,P＜0.001)低于对照组，同时，观察组透析中低血压发生率(χ2=10.107,P =0.001)及平均血压下降值(t=-4.429,P＜0.001)显著低于对照组。 结论 空气波压力治疗可降低透析相关肌肉痉挛和低血压的发生率，并能减轻肌肉痉挛和低血压发生时的程度。
Objective To explore the role of air wave pressure therapy in the prevention of hemodialysis-associated muscle cramps. Methods A total of 47 patients with three or more hemodialysis-associated muscle cramps occurring within one month during the monitoring period and treated in the Blood Purification Center of Shaoxing Second Hospital were divided into the observation group (24 cases) and the control group (23 cases). The control group was treated with routine hemodialysis. The observation group was treated with routine hemodialysis plus air wave pressure. The occurrence of muscle cramps and hypotension were compared between the two groups. Results Compared with the control group, the incidence of hemodialysis-associated muscle cramps (14.5% vs. 26.2%; χ2=12.797, P＜0.001), and the mean modified Ashworth score (1.31±0.51 vs. 1.79±0.71; t=-4.006, P＜0.001) were lower in the observation group; the incidence of hypotension (13.2% vs. 23.2%; χ2=10.107, P=0.001) and the mean decrease of blood pressure (22.66±2.45 vs. 25.28±3.75 mmHg; t=-4.429, P＜0.001) were also lower in the observation group. Conclusion Air wave pressure therapy can reduce the incidence and the degree of hemodialysis-associated muscle cramps and hypotension.
