Influence of repeated PICC catheterized on catheter tip location

Abstract

Objective To explore the influence of repeatedly PICC catheterized on catheter tip position. Methods We analyzed the catheter tip position of patients who located PICC in one level three class-A hospital in Beijing from May to October in 2014. A total of 381 effective medical records were collected and divided into having the history of catheterization group and having no history of catheterization group depending on patients whether catheterized before. The patients having the history catheterization were divided into ipsilateral catheter group (B1 group) and no ipsilateral catheter group (B0 group), the catheter tip position was compared. Results The best catheter tip position for patients having the history of catheterization was 30.79%, which was lower than patients having no history group of 52.66% (χ2=17.565, P<0.01), and the patients of having catheterization history group had the incidence rate of shallow catheterization (47.74%) higher than 35.40% in the no catheterization history group (χ2=5.817, P<0.05). The patients of having catheterization history group happened the incidence of catheter tip position acquired dystopia of venae subclavia higher than patients having no catheterization history group (P<0.05). The best catheter tip position had lower rate in the B1 group comparing with B0 group, but the patients acquired dystopia of venae subclavia in the B1 group was lower than the patients in the B0 group (P<0.05). Conclusions Multiple PICC catheterization reduces the accuracy of catheter tip position, and impacts the safety and reservation of PICC. We should minimize the non-planned extubation incidences. If patients require re-catheterizaiton, we should select the opposite limbs to catheterize without catheterizaiton contraindication to ensure the safe of PICC catheterization.
