直型留置针改良操作流程效果观察

目的 观察直型安全留置针改良操作流程的临床应用效果.方法 将200例使用直型安全留置针静脉穿刺的手术患者随机分为对照组和观察组,对照组采用德国贝朗公司培训的操作流程,套管进入血管后,操作者左手用"V"形加压法,即中指按压套管尖端血管,食指固定针梗,同时右手拔出针芯,连接已排气的延长管及输液器.观察组采用改良后的操作流程,套管进入血管后,不使用"V"形加压法按压套管尖端血管,而采用操作者将患者前臂抬高约60°,同时左手稍固定针梗,右手拔出针芯,观察外套管中的血液即将到达管口时,连接已排气的延长管及输液器.结果 观察组1次穿刺成功率高于对照组,操作时间短于对照组(P<0.05或P<0.01);观察组血液回流污染率低于对照组(P<0.01).结论 直型安全留置针的改良操作流程可缩短操作时间,提高穿刺成功率,减轻患者静脉穿刺的痛苦,降低感染风险.

Clinical Value of Improved Operation Process of Straight Catheter

Objective To observe the clinic value of improved operation process of straight catheter.Methods 200 patients with venous puncture using straight catheter were randomly divided into control group and experiment group.Patients in control group were treated with operating procedure from Germany Brown Company while patients in experiment group were treated with improved operational procedure.Results The successful rate in experiment group was higher and the operating time was shorter than those of control grou...
