应用鱼骨图在降低封管后留置针内残留血液的作用

摘要

目的：了解心血管疾病患者封管后静脉留置针内残留血液的情况，探讨应用鱼骨图对降低封管后留置针内残留血液的作用。方法按入院时间先后次序，将293例（1035例次）行静脉留置针封管的心血管疾病患者设为对照组，将272例（1276例次）行静脉留置针封管的心血管疾病患者设为实验组。对照组采用常规静脉留置针封管方法；实验组应用鱼骨图找出影响留置针内残留血液的关键因素，制订和实施针对性干预措施，比较两组患者留置针内残留血液发生率的差异。结果封管后，实验组患者留置针内残留血液发生率低于对照组，两组比较，差异有统计学意义（P＜0.05）。结论通过应用鱼骨图找出影响心血管疾病患者留置针内残留血液的关键因素，采用针对性干预措施，可降低封管后留置针内残留血液发生率。%Objective To investigate the influence of fishbone diagram in the incidence of blood residual after sealing tube indwelling needle in cardiovascular disease patients.Methods Two hundred and ninety-three patients(1,035 times)with sealing tube intravenous indwelling needle were assigned into control group and another 272 ones(1,276 times)with the needle into experiment group according to admission sequence. In the former group the method of conventionally sealing the tube for intravenous indwelling needle was applied and in the latter,fishbone diagram was applied to analyze the key factors for blood residuals and regulate pertinent measures for effective sealing of tube.The two groups were compared in terms of incidence of blood residuals.Result The incidence of blood residuals in the experiment group was significantly lower than that in the control group(P<0.05).Conclusion The fishbone diagram is effective in reducing the incidence of blood residuals after sealing the tube for intravenous indwelling needle by way of taking effective interventional measures after screening out the key influential factors for blood residuals.
