ObjectiveTo explore the effect of targeted nursing intervention on prevention of neonatal peripherally inserted central catheter (PICC)-associated phlebitis under risk factor assessment.

MethodsA total of 1 164 patients with PICC catheterization in neonatal intensive care unit of a tertiary grade A hospital from 2017 to 2019 were retrospectively analyzed.According to whether PICC-associated phlebitis occurred or not, the patients were divided into the phlebitis group (142 cases) and non-phlebitis group (1 022 cases).The risk factors of catheter-associated phlebitis were analyzed by univariate analysis.A total of 78 children with PICC catheterization with any one or more risk factors in PICC catheterization from 2020 to 2021 were selected as the study objects, and randomly divided into control group (40 cases) and observation group (38 cases).The control group was given routine maintenance and care after successful catheterization, and the observation group took targeted nursing intervention based on risk factors assessment during catheterization.The incidence of PICC-associated phlebitis was compared between the two groups.

ResultsThe body weight in the group with phlebitis was lower than that in the group without phlebitis (P < 0.05), the incidence of catheter tip position ectopic rate, catheterization difficulty rate, no using of 0.9% sodium chloride injection and 5 mg dexamethasone immersion catheter before catheterization were higher than those in non-phlebitis group (P < 0.05 to P < 0.01), and the difference of puncture vein between the two groups was statistically significant (P < 0.01).The incidence of phlebitis in the observation group was significantly lower than that in the control group (P < 0.01).

ConclusionsTargeted nursing intervention can reduce the incidence of neonatal PICC-associated phlebitis under risk factor assessment.
