Abstract:
Objective:To explore the correlation between the length of peripherally inserted central catheter (PICC) through upper and lower extremities of premature infants and their body parameters, and to deduce the formula of the different length of PICC of premature infants, so as to improve the accuracy of the tip of PICC in premature infants.Methods:This study was a retrospective case series study.From January 2016 to September 2021, 758 premature infants with PICC hospitalized in Neonatal Intensive Care Unit (NICU) of Shanghai Children's Hospital were selected retrospectively by convenience sampling. We recorded the sex, gestational age, catheterization age, catheterization vessel location, birth length, length on the day of catheterization, birth weight and weight on the day of catheterization of premature infants. Pearson correlation analysis and simple linear regression were used to find the most relevant body parameters, and formula fitting was carried out to derive the optimal length of PICC for premature infants.Results:In 652 premature infants (86.02%, 652/758) , the PICC was placed in the lower limb vein, and the proportion of great saphenous vein was the highest, accounting for 41.42% (314/758) . Simple linear regression showed that the weight and length had the highest correlation with the optimal length of PICC in the superficial veins of the upper and lower extremities. The formula for the length of PICC with the puncture points of median vein, basilic vein, axillary vein, great saphenous vein, small saphenous vein, popliteal vein and femoral vein was derived.Conclusions:The formula derived from the weight and length of premature infants can provide a reference for clinical measurement of PICC length of premature infants.
