Does intracavitary electrocardiogram guidance accurately determine peripherally inserted central catheter tip location compared to chest X-ray in premature infants?
p-value: p=>0.05
Intracavitary electrocardiogram guidance is an accurate, economical, and radiation-free method for confirming peripherally inserted central catheter tip placement in premature infants.
Should not yet replace chest X-ray for PICC placement in premature infants; leaves open potential for radiation-free guidance pending larger studies.
This study evaluated the accuracy of intracavitary electrocardiogram (IC-ECG) guidance for placement of peripherally inserted central catheters (PICCs) in premature infants, relative to chest X-ray.Premature infants (n = 173) underwent placement of a PICC monitored by ECG, and a stable heart rhythm was shown. Changes in the P wave of the ECG reflected the position of the catheter tip, and a characterized P wave indicated the correct position. The P wave results were compared with a chest X-ray.P wave changes were observed in 157 (90.75%) of the premature infants on the ECG. Among them, the catheter tips of 148 (85.55%) and nine (5.20%) patients were in the correct and non-correct position, respectively, which was confirmed by chest X-ray. No characteristic P wave changes were observed in 16 (9.32%) patients on ECG, in which the catheter tips of eight (4.62%) patients each were in the correct and non-correct position, according to the chest X-ray. The accuracy of IC-ECG guidance for placement of the PICC was 90.17%. The PICC tip location results of the IC-ECGs were statistically similar to that of the chest X-rays.IC-ECG guidance is accurate for placement of PICC in premature infants, and provides an economical assessment without radiation.

Yang et al. (2019) conducted an observational in Premature infants requiring peripherally inserted central catheters (n=173). Intracavitary electrocardiogram (IC-ECG) guidance vs. Chest X-ray was evaluated on Accuracy of IC-ECG guidance for placement of PICC (p=>0.05). Intracavitary electrocardiogram guidance accurately predicted the correct position of peripherally inserted central catheters in 90.17% of premature infants, with results statistically similar to chest X-ray.
