Application effect of synchronous disinfection of lower limbs in PICC puncture of very low birth weight infants

Abstract

Objective To explore the study of synchronous disinfection of lower limbs and unilateral limb disinfection when peripheral inserted central catheters is inserted into the lower limbs of very low birth weight infants, and to find a better and safer method of puncture disinfection. Methods Total of 30 cases of children who received unilateral limb disinfection from January 2016 to February 2017 were selected as the control group, and 30 cases of children who received simultaneous disinfection of both lower limbs from March 2017 to June 2018 were selected as the experimental group, and non-random and non-synchronous control studies were conducted. The operation time, blood loss, times of placing sterile table and retained site of the two groups were analyzed retrospectively. Results The operation time of synchronous disinfection of lower limbs in the experimental group and the control group were (43.67±28.04) min, (60.33±35.40) min; the amount of blood loss were (1.64±0.90) ml, (2.34±1.50) ml, the differences were statistically significant (t values were 2.021, 2.176, P<0.05). In the control group, 76% (21/30) completed the PICC operation after laying a sterile operation table, while in the experimental group, 96% (28/30) did. In the control group, 5 cases were successfully indwelling via femoral vein, and in the experimental group, 2 cases were successfully indwelling via femoral vein. Conclusion The method of simultaneous disinfection of lower limbs increases the selection of peripheral veins, reduces the frequency of sterile table, blood loss and operation time, and reduces the number of inguinal vein puncture, which is relatively safe and effective.
