Objective  To explore the value of ultrasound monitoring assisted with electrocardiogram guidance in head location of peripherally inserted central catheter (PICC).

  Methods  Totally 120 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.
