目的 探讨安全型静脉留置针在无痛人流手术中的应用效果。方法 将1500例实施无痛人流术的患者按照数字表法随 机分为两组，对照组751例给予一次性静脉输液针穿刺静脉；观察组749例给予静脉留置针穿刺静脉，并比较两组穿 刺部位针头脱出、局部肿胀等并发症发生情况及再次穿刺效果。结果 观察组的病人全部手术顺利完成，发生液体 外渗率明显地低于对照组(P＜0.05)；针头脱出、局部肿胀并发症发生率也明显地低于对照组(P＜0.05)，再次穿刺 率而显著的低于对照组(P＜0.05)。结论 静脉留置针能够完全的避免让病人遭受反复穿刺的烦恼与痛苦，大大的降 低了病人的血管损伤，这样就完全杜绝了针头脱出、二次穿刺、麻醉药物渗漏等情况发生，为手术的顺利实施提供 有效的保障，大大提升护理人员的工作效率和质量。

Objective To explore the safe venous indwelling needle in the application of painless abortion effect. Methods The painless abortion methods 1500 cases of patients according to digital table method were randomly divided into two groups, control group with 751 cases of disposable venous infusion needle puncture veins. Observation group 749 cases were given intravenous indwelling needle puncture veins, and compare the two groups of puncture needle out, local swelling and other complications occurred and puncture effect again. Results Observation group patients surgery is completed, fluid extravasation occurred rate is obviously lower than that of control group (P<0.05). Needle out, local swelling complications is obviously lower than that of control group (P<0.05), and once again the puncture rate and significantly lower than that of control group (P<0.05). Conclusion Intravenous indwelling needle can completely avoid bothers patients suffered from repeated puncture and pain, greatly reducing the patient's blood vessel damage, thus to completely eliminate the needles out and secondary piercing, anesthetic leakage happens, provide effective guarantee for the smooth implementation of the operation, greatly improve work efficiency and quality of nursing staff.
