Key result
PICC tip positioning at the autonomous peak of the P wave improved optimal position compliance and reduced 90-day complications compared to positioning at 50-80% of the QRS main wave (P<0.05).
Why the study?
It was unclear which of two forward P-wave amplitudes during intracavitary electrocardiogram guidance determines optimal PICC tip position to prevent catheter-related complications.
Does positioning the PICC tip at the autonomous peak of the P wave improve optimal tip location and reduce complications compared to positioning at 50-80% of the QRS main wave in cancer patients?

p-value: p=<0.05
Positioning the PICC tip at the autonomous peak of the P wave using IC-EKG improves optimal tip location and reduces catheter-related complications in cancer patients.
Wang et al. (2021) conducted a cohort in Cancer patients requiring peripherally inserted central catheter (PICC) (n=300). PICC tip positioning at the autonomous peak of the P wave vs. PICC tip positioning at the P wave amplitude being 50-80% of the QRS main wave was evaluated on Total compliance rate, optimal position compliance rate, and incidence of catheter tip malposition (p=<0.05). PICC tip positioning at the autonomous peak of the P wave improved optimal position compliance and reduced 90-day complications compared to positioning at 50-80% of the QRS main wave (P<0.05).
