Abstract：Objective To study the efficiency of electrocardiogram (ECG) monitor for positioning the catheter tip in the placement of peripherally inserted central venous catheterization (PICC) via lower extremity veins in neonates. Methods A total of 120 neonates who were admitted to the neonatal intensive care unit from January 2020 to January 2022 and received PICC via lower extremity veins were enrolled and divided into a control group and an observation group using a random number table (n=60 each). The neonates in the control group were given body surface measurement and postoperative chest X-ray localization, and those in the observation group were given body surface measurement, ECG-guided positioning, and postoperative chest X-ray localization. The two groups were compared in terms of general information, one-time success rate of PICC placement, and time spent on PICC placement, and the efficiency of ECG-guided positioning was evaluated. Results Compared with the control group, the observation group had a higher one-time success rate of PICC placement (92% vs 75%; P<0.05) and a shorter time spent on PICC placement [(26.5±3.0) min vs (31.8±2.8) min; P<0.05]. ECG-guided positioning had a sensitivity of 90.9% and a specificity of 100% in the PICC placement via lower extremity veins in neonates. Conclusions ECG monitor helps to determine the position of catheter tip in the PICC placement via lower extremity veins in neonates and can improve the one-time success rate of PICC placement and reduce the time spent on PICC placement, with a good positioning efficiency.
