目的:观察医用微创术后压迫止血带用于肾穿刺术后防护的效果。方法:选择住院拟行肾穿刺活检且有肾穿刺危险因素的患者60例,随机分为观察组和对照组各30例。观察组肾穿刺术后采用自行研制的医用微创术后压迫止血带,对照组肾穿刺术后平卧位使用普通盐袋垫压腰部。观察比较两组术后卧床时间、自行翻身情况、舒适度及并发症发生情况。结果:(1)观察组术后卧床时间(4.73±0.36)h,显著短于对照组的(6.13±0.23)h(P<0.05)。首次观察尿色前,观察组30例(100.0%)均可自行翻身,对照组为7例(23.3%);两组比较差异非常显著(P<0.01)。观察组术后出现腰背酸痛、短暂肢体麻木和睡眠质量差的比例,均非常显著低于对照组(P<0.01)。(2)观察组并发症发生率非常显著低于对照组(P<0.01),两组均无一例发生尿潴留。结论:医用微创术后压迫止血带应用于肾穿刺术后防护,可缩短术后卧床时间,改善患者舒适度,减少并发症。 Objective: To observe the effect of medical minimally invasive compression tourniquet for protection after renal paracentesis. Methods: Sixty patients who were hospitalized for renal biopsy and had risk factors for renal biopsy were randomly divided into observation group (30 cases) and control group (30 cases). The observation group received self-developed medical minimally invasive tourniquet tourniquet after renal puncture. The control group received general saline bag supine position in the supine position after renal puncture. Observe and compare the two groups after bed rest time, stand up their own situation, comfort and complications. Results: (1) The bed rest time in the observation group (4.73 ± 0.36) h was significantly shorter than that in the control group (6.13 ± 0.23) h (P <0.05). Before the first observation of urine color, 30 cases (100.0%) in the observation group were able to turn over themselves, and 7 cases (23.3%) in the control group. The difference between the two groups was significant (P <0.01). The proportion of postoperative back pain, short limb numbness and poor sleep quality in the observation group were significantly lower than those in the control group (P <0.01). (2) The incidence of complication in the observation group was significantly lower than that in the control group (P <0.01), and urinary retention was not found in either group. Conclusion: Medical minimally invasive postoperative compression tourniquet is applied to the postoperative protection of renal puncture, which can shorten the postoperative bed rest time, improve patient comfort and reduce complications.
