Objective To explore the value of ultrasound monitoring assisted with electrocardiogram guidance in head location of peripherally inserted central catheter (PICC). Methods Totally120 malignant tumor patients with PICC treatment were randomly divided into observation group and control group, with 60 cases in each group. The control group was treated with the routine chest X-ray to locate the head of PICC, while the observation group was treated with the intracavitary electrocardiogram technique and the ultrasonic guidance detection technique to locate the head of PICC. The condition of head of PICC in position, postoperative complications and satisfaction degree to PICC were compared between the two groups. Results The rate of head of PICC in position in the observation group was 93. 3％, which was significantly higher than 71. 7％ in the control group (P ＜ 0. 05). The incidence rate of complications was only 5. 0％ in the observation group, which was significantly lower than 31. 7％ in the control group (P ＜ 0. 05). The satisfaction degree to PICC catheterization and nursing in the observation group was 91. 7％, which was significantly higher than 65. 0％ in the control group (P ＜ 0. 05). Conclusion The PICC catheterization by ultrasound monitoring assisted with electrocardiogram guidance can accurately locate the head position of the PICC tube and reduce the incidence rate of postoperative complications.%目的 探讨超声监测辅助心电图引导经外周静脉穿刺置入中心静脉导管(PICC)头端定位的价值.方法 选取PICC置管治疗的恶性肿瘤患者120例,随机分为观察组与对照组,每组60例.对照组采用常规胸部X线片定位PICC头端位置的方式进行置管,观察组采用腔内心电图技术和超声监测技术对患者PICC管进行头端定位.比较2组患者头端到位情况、术后并发症发生情况以及对于PICC置管术的满意情况.结果 观察组患者头端到位率达到93.3％,显著高于对照组患者的71.7％(P ＜0.05).观察组并发症发生率只有5.0％,显著低于对照组的31.7％(P ＜0.05).观察组患者对于PICC置管术及后期护理的满意率达到91.7％,显著高于对照组的65.0％(P ＜0.05).结论 采用超声监测技术辅助腔内心电图引导PICC置管术,能够较为精准地对PICC管进行头端定位,降低术后并发症发生率.
