Discussion On The Frequency Of Using Physiological Saline To Flush And Seal The Tube Of Neonatal Intravenous Indwelling Needle

Objective: to explore the effect of 0.9% sodium chloride on the indwelling of neonate in the course of indwelling transfusion.Methods: From January 2017 to December 2017,157 newborns who were treated in pediatrics department of a hospital in Shijiazhuang City with intermittent infusion were collected,including 91 male and 66 female,whose minimum age was 20 minutes after birth.The maximum age is 22 days after birth.use 0.9% sodium chloride sealing tube was divided into four groups by random grouping according to the different fluid volume and frequency of sealing tube,and group A 0.9% sodium chloride for 8 h,5 ml;group B: 0.9% sodium chloride for 12 h,5 ml;group C: 0.9% sodium chloride for 8 h,2 ml;groupD: 0.9% sodium chloride for 12 h,2ml.The plugging rate,phlebitis rate,extubation rate and retention time were recorded.Chi-square test was used to compare the catheter occlusion rate,phlebitis rate and extubation rate between group A and group B and group D and group C respectively.Two independent sample nonparametric tests were used to compare the difference of retention time between group A and group B,group C and group D,group A and group C,group B and group D.Results: There was no significant difference between group B and group A in the rate of catheterization and extubation.The incidence of phlebitis in group B was lower than that in group A.There was significant difference in retention time between group B and group A.the retention time of group B was longer than that of group A.The incidence of phlebitis in group D was lower than that in group C(P> 0.05).The retention time of group D was longer than that of group C(P= 0.000),but the blocking rate of indwelling needle in group D and group B was significantly lower than that in group C(P = 0.000).There was no significant difference in the incidence of phlebitis,the rate of extubation and the retention time.Conclusion: The use of 0.9% sodium chloride to seal the tube is beneficial to the indwelling of the needle because of the low volume of fluid and the long interval of the percussion tube associated with less complications and longer retention time.
