Abstract

Abstract:

Objective To design and produce a bleeding alert bandage and investigate its effectiveness in patients undergoing hemodialysis. Methods The bleeding alert bandage consists of elastic bandage，monitoring element and monitoring box. A convenience sampling method was used to select patients who received regular hemodialysis treatment in the blood purification center of a tertiary A comprehensive hospital in Anhui Province from January 2021 to June 2021. These patients were randomly assigned into an experimental group and a control group，with 40 cases in each group. Patients in the control group were inspected every 30 min by traditional method. Patients in the experimental group were monitored in real-time with a bleeding alert bandage in addition to the 30 min rounds. The detection rate，incidence，and volume of bleeding at the puncture site were compared in 2 groups of patients. Results The incidence of bleeding from the puncture sites was 17.00% in the experimental group and 25.25% in the control group，with statistical significance（χ²=8.170，P=0.004）. The incidence of bleeding for severe bleeding from puncture sites was 1.50% in the experimental group and 11.50% in the control group，with statistical significance（χ²=32.910，P<0.001）. The bleeding detection rate from puncture sites was 94.12% in the experimental group and 89.11% in the control group，with no statistical difference（χ²=1.261，P=0.262）. The detection rate for moderate bleeding from puncture sites was 100% in the experimental group and 85.37% in the control group，with statistical significance（χ²=6.170，P=0.013）. Additionally，the bleeding volume from the puncture site was 1.29（0.88，1.74） g in the experimental group and 2.77（1.60，4.77） g in the control group，with statistical significance（Z=-5.825，P<0.001）. The moderate bleeding volume from the puncture site was 1.49（1.27，1.81） g in the experimental group and 1.92（1.52，2.44） g in the control group，with statistical significance（Z=-2.835，P=0.005）. Conclusion The bleeding alert bandage is effective in real-time monitoring and alerting of bleeding at the puncture sites during hemodialysis，which can help reduce the incidence of blood seepage，improve the detection rate of blood seepage，reduce the amount of bleeding and improve the safety of dialysis treatment.

摘要：

目的设计、制作维持性血液透析患者出血报警绷带，并探讨其应用效果。方法出血报警绷带由弹力绷带、监测元件和监测盒组成。采用便利抽样法，选取2021年1月—6月在安徽省某三级甲等综合医院血液净化中心接受规律血液透析治疗的患者，采用随机数字表法分为试验组和对照组，每组各40例。试验组每次上机后在每30 min巡视1次的基础上使用出血报警绷带实时监测；对照组每次上机后每30 min巡视1次，比较两组的穿刺点渗血发生率、发现率及渗血量的差异。结果试验组穿刺点渗血发生率为17.00%，对照组穿刺点渗血发生率为25.25%，两组比较差异具有统计学意义（χ²=8.170，P=0.004）；其中试验组穿刺点重度渗血发生率为1.50%，对照组穿刺点重度渗血发生率为11.50%，两组比较差异具有统计学意义（χ²=32.910，P<0.001）。试验组穿刺点渗血发现率为94.12%，对照组穿刺点渗血发现率为89.11%，两组比较差异无统计学差异（χ²=1.261，P=0.262）；其中试验组中度渗血发现率为100%，对照组穿刺点中度渗血发现率为85.37%，两组比较差异具有统计学意义（χ²=6.170，P=0.013）。试验组穿刺点渗血量为1.29（0.88， 1.74） g，对照组穿刺点渗血量为2.77（1.60，4.77） g，两组比较差异具有统计学意义（Z=-5.825，P<0.001）；其中试验组穿刺点中度渗血量为1.49（1.27，1.81） g，对照组穿刺点中度渗血量为1.92（1.52，2.44） g，两组比较差异具有统计学意义（Z=-2.835，P=0.005）。结论使用出血报警绷带可有效对维持性血液透析患者穿刺点渗血情况进行实时监测及报警，有助于降低渗血发生率，提高渗血发现率，减少渗血量，提高透析治疗的安全性，保障透析护理质量。
