PICC置管加温充气固定装置的设计和应用

目的 探讨自主研发的加温充气固定装置在PICC置管中的应用效果。方法 将428例拟行PICC置管术的肿瘤患者随机分为两组。对照组224例在超声引导下行PICC置管,干预组204例在此基础上,采用自制的加温充气固定装置行PICC置管。结果 干预组一次穿刺成功率、一次置管成功率显著高于对照组,术中疼痛评分显著轻于对照组（均P<0.05）。干预组穿刺置管时间显著短于对照组,机械性静脉炎及导管相关性血流感染发生率显著低于对照组（均P<0.05）。结论 PICC置管加温充气固定装置的应用可提高PICC置管效率,降低相关并发症发生率。

Design and application of heated inflatable fixation device in PICC placement

Objective To explore the effect of using a self-invented heated inflatable fixation device in PICC placement. Methods A total of 428 patients to receive PICC placement were selected and randomly divided into 2 groups. The control group (n=224) received routine PICC placement under the guidance of ultrasonography, while the intervention group (n=204) additionally used a self-invented heated inflatable fixation device to secure the punctured arm during the procedure. Results The 1-puncture success rate, and 1-insertion success rate in the intervention group were significantly higher than those in the control group; the former group also reported less pain than the latter group (all P<0.05). The intervention group had shorter time in PICC placement, and lower incidence rates of mechanical phlebitis and catheter-related blood stream infection, than the controls (all P<0.05). Conclusion The usage of the heated inflatable fixation device improves the efficiency of PICC placement, and reduce the incidence of placement related complications.
