Research On The Effect Of Different Methods In Alleviating Venipuncture Pain In Premature Infants

Objective Analyze and compare the effects of breastmilk sucking+oral massage,breastmilk sucking and non-nutritive sucking on the relief of puncture pain of premature infants,so as to provide reference for clinic.Methods In this study,120 premature infants admitted to the neonatal care unit of our hospital from 1^stFebruary,2018 through 1^stFebruary,2019 were randomly divided into three groups:the experimental group,the breastmilk group and the non-nutritional sucking group,with 40 cases in each group.Two minutes before venipuncture,the experimental group received breastmilk+oral massage.In the breastmilk group,breastmilk was given by feeding-bottle.Non-nutritional sucking group was given non-nutritional sucking by comfort nipple.Blood oxygen saturation,heart rate,NIPS neonatal pain assessment scale,crying and painful face were used as evaluation indexes to evaluate and compare the changes of the three groups of newborns after sucking intervention.Results（1）there were no differences in the age,sex,gestational age and birth weight of the three groups of premature infants（P>0.05）.There was no difference in blood oxygen saturation and heart rate before puncture（P>0.05）.（2）the three groups of premature infants had the highest pain scores during venipuncture,followed by the recovery period.In the puncture period and recovery period,there was a difference in the NIPS scores between the three groups of premature infants（P<0.05）.At the puncture stage,there was significant difference between the non-nutritional group and the experimental group（P<0.05）.There wassignificant difference between the breastmilk group and the experimental group（P<0.05）.At the recovery stage,there was no significant difference between the experimental group and the breastmilk group（P>0.05）.（3）there were differences in the three groups of premature infants’crying（P<0.05）.The comparison between the experimental group and the non-nutritional sucking group（P<0.05）was statistically significant.There was no significant difference between the experimental group and the breastmilk group（P>0.05）.（4）the duration of painful facial features in the experimental group and breastmilk group was less than that in the non-nutritional sucking group,with significant difference（P<0.05）.Compared with the breastmilk sucking group,the duration of pain in the experimental group was shorter,and the difference was statistically significant（P<0.05）.（5）the pulse oxygen saturation of the three groups decreased to different degrees,the decrease extent of the experimental group and the breastmilk group was smaller than that of the non-nutritional sucking group（P<0.05）.Heart rate index of the three groups increased to different degrees,the experimental group and breastmilk sucking group increased less than the non-nutritional sucking group（P<0.05）.There were significant differences in pulse oxygen saturation and heart rate between the experimental group and the non-nutritional sucking group（P<0.05）.Conclusion Both breastmilk+oral massage and breastmilk sucking can effectively relieve premature venipuncture pain,the effect of the two ways are better than that of non nutritional sucking,and the effect of breastmilk+oral massage is best,this way can not only reduce the NIPS score,crying,but also promote the recovery of facial,pulse oxygen saturation and heart rate,worthy of application and popularization.
