【摘要】 目的探讨减少浅静脉留置针保护膜更换次数,延长静脉留置针留置时间,减少静脉炎发生的方法。方法将120例使用浅静脉留针患者随机分为保护膜开窗组(开窗组)和保护膜随时更换组(随时组)。开窗组穿刺后将保护膜中间开一窗口贴于穿刺处,用一次性输液敷贴覆盖,每天消毒穿刺口,并更换输液敷贴,除保护膜与皮肤分离外,不更换保护膜;随时组视保护膜污染状况随时进行更换。结果随时组保护膜内积气、出汗,穿刺口红肿、疼痛发生率明显高于开窗组(P<0.01、P<0.05),保护膜更换次数明显多于开窗组(P<0.01);而静脉针留置时间开窗组明显长于随时组(P<0.01)。结论保护膜开窗法能减少保护膜的更换次数,延长静脉针的留置时间。更多还原

【Abstract】 Objective To explore a way of reducing the number of protective membranes for venous catheter and extending the time for needle-dwelling time and reducing the incidence of phlebitis. Methods One hundred and twenty patients were randomly divided into an experimental group and a control group. In the experimental group, a hole was opened on the protective membrane and the puncture site was covered with plasters used for disposable infusion set. The puncture site was subjected to disinfection and the plaster was changed on daily basis. The protective membrane was not changed until the membrane was detached from skin. The protective membrane would be changed at any time if the membrane was contaminated. Results The incidences of trapped bubbles, sweating, redness and swelling of puncture sites were significantly higher than those of the experimental group (P<0.01, P<0.05). The times for membrane change were less than those of the controls (P<0.01) and the dwelling time of venous catheter in the experimental group was significantly longer than that of controls (P<0.01). Conclusion The modified technique can reduce the times of membrane change and prolong the dwelling time of venous catheter.更多还原
