Abstract:
Objective:To study the clinical application of ultrasound-guided puncture and catheter tip positioning in peripherally inserted central catheter (PICC) among very/extremely low birth weight infants (VLBWI/ELBWI).Method:From January 2019 to August 2020, VLBWI/ELBWI admitted to NICU of our hospital and received PICC were prospectively enrolled in the study. Based on the last digit of medical record number was odd or even, the infants were assigned into ultrasound group and X-ray group. In the ultrasound group, puncture and catheter tip positioning were performed at bedside guided by ultrasound, while in the X-ray group, these procedures were performed empirically. The differences of catheterization procedure duration, first-time success rate, the visibility of catheter tip, primary dislocation rate, secondary dislocation rate and complication rate were compared between the two groups using SPSS 25.0.Result:A total of 118 premature infants were enrolled, including 57 cases in ultrasound group (50 cases VLBWI and 7 cases ELBWI) and 61 cases in X-ray group (54 cases VLBWI and 7 cases ELBWI). The catheterization procedure duration [(23.2±7.1) min vs. (34.1±7.5) min], first-time success rate (93.0% vs. 65.6%), the visibility of catheter tip (96.5% vs. 83.6%), primary dislocation rate (7.0% vs. 24.6%) and complication rate (7.0% vs. 21.3%) in ultrasound group were all better than X-ray group ( P<0.05). For ELBWI, the above five indexes in the ultrasound group were better than the X-ray subgroup ( P<0.05). For VLBWI, only the catheterization procedure duration and first-time success rate were better in the ultrasound group than the X-ray group ( P<0.05). Conclusion:Ultrasound-guided PICC catheterization in VLBWI/ELBWI is convenient and accurate, which can improve success rate, reduce radiation exposure and repeated catheterization injury. Timely tracking and adjustment of the catheter under ultrasound can reduce complications after catheterization. This technique is worth popularizing among VLBWI/ELBWI.
