Effect of heating skin disinfectant for premature infants during peripheral central venous catheterization / 中国新生儿科杂志

ABSTRACT

Objective:To study the effect of heating skin disinfectant during peripherally inserted central catheter (PICC) in preterm infants.Methods:Premature infants were retrospectively analyzed who received PICC catheterization during hospitalization in the Department of Neonatology of the Affiliated Hospital of Southwest Medical University from April 2020 to March 2021. They were divided into the control and heating groups according to different disinfection methods in two different periods. The skin of premature infants in the heating group was disinfected with disinfectant at 37℃, and the control group was disinfected with room temperature disinfectant. The rate of successful primary catheterization, operation duration, and catheter-associated infection were compared between the two groups.Results:The rate of successful primary catheterization in the heating group was higher than that of the control group [80.2% (65/81) vs. 66.7% (56/84)], and the operation time was shorter than that of the control group [(45.0±9.0) min vs. (48.4±11.9) min] ( P<0.05). There was no statistical difference in catheter keeping time, unplanned extubation rate, the rate of positive catheter tip cultures, and the blood cultures. Conclusions:During PICC puncture in premature infants, heating skin disinfectant can increase the success rate of one-time PICC catheterization, reduce the operation duration, and not increase the risk of catheter-associated infection.
