Effect Of Sensorial Saturation On Pain Caused By Femoral Vein Blood In Premature Infants

Objective:Based on gate control theory and comfort theory,we constructed a sensorial saturation intervention program to investigate the intervention effects of sensorial saturation on pain,physiological indicators,behavioral indicators,comfort score and incidence of adverse outcomes due to femoral vein blood in preterm infants,in order to provide reference for enriching non-pharmacological analgesic management strategies for neonates.Methods:130 premature infants with gestational age of 32-36⁺⁶ weeks who were admitted to the Neonatal Department of a 3A hospital in Shanxi Province from September 2021 to December2022 were selected as the research object.Sixty-five premature infants hospitalized from September 2021 to April 2022 were selected as the control group and 65 premature infants hospitalized from May to December 2022 as the intervention group.The control group received routine nursing care in the process of femoral vein blood collection.On the basis of the control group,the intervention group received sensorial saturation method such as 10%glucose,massage and touching,gentle soothing,reducing ambient light and noise,etc.The application effects of two kinds of intervention measures to relieve pain were analyzed and compared by using the revised Premature Infant Pain Profile Revised（PIPP-R）,including physiological indicators such as heart rate and blood oxygen saturation,behavioral indicators such as pain duration and crying number,comfort and the incidence of adverse outcomes.Results:The study finally included 120 preterm infants,60 in the control group and 60 in the intervention group.The research results showed that.1.There was no statistically significant difference in general information,pre-puncture behavioral status,and corrected gestational age between the two groups of preterm infants（P>0.05）,and the two groups were comparable.2.On the Premature Infant Pain Profile Revised（PIPP-R）.（1）the difference in PIPP-R scores between the two groups of preterm infants at baseline was not statistically significant（P>0.05）;（2）the PIPP-R scores of preterm infants in the intervention group during the operation and recovery periods were lower than those in the control group,and the difference was statistically significant（P<0.05）;（3）the differences in the PIPP-R scores of preterm infants in the two groups after the intervention in terms of between-group factors,time factor,time factor,and interaction effect differences were statistically significant（P<0.001）.3.In terms of physiological indicators（heart rate,oxygen saturation）.（1）Heart rate:the difference in heart rate between the two groups of preterm infants at baseline was statistically significant（P=0.020）;the change in heart rate of preterm infants in the intervention group during the operation and recovery periods was lower than that in the control group,and the difference was statistically significant（P<0.05）;the differences in the between-group factors,time factors,and interaction effects of heart rate between the two groups of preterm infants after the intervention were statistically significant（P<0.001）.（2）Oxygen saturation:the difference in oxygen saturation between the two groups of preterm infants at baseline was not statistically significant（P>0.05）;the oxygen saturation of preterm infants in the intervention group during the operation and recovery periods was higher than that in the control group,and the difference was statistically significant（P<0.05）;the differences in the intergroup factors,time factors,and interaction effects of oxygen saturation between the two groups of preterm infants after the intervention were statistically significant（P<0.001）.4.In terms of behavioral indicators（duration of pain face,number of cries）:（1）Duration of pain face:the duration of pain face of preterm infants in the intervention group was（12.43±6.09）s,which was lower than that of the control group（39.32±8.96）s.The difference was statistically significant（P<0.05）.（2）The number of crying:39 cases of crying in preterm infants in the intervention group and 48 cases of crying in preterm infants in the control group,the difference between the two groups was not statistically significant（P>0.05）.5.On the Comfort Behavior Scale for Newborns（COMFORTneo scale）scores:（1）the differences in comfort scores between the two groups of preterm infants at baseline were not statistically significant（P>0.05）;（2）the comfort scores of preterm infants in the intervention group during the operation and recovery periods were lower than those in the control group,and the differences were statistically significant（P<0.05）;（3）the differences in comfort scores of preterm infants in the two groups after the intervention in terms of between-group factors,time factors,and The differences of interaction effects were statistically significant（P<0.001）.6.In terms of safety indicators:there was no statistically significant difference between the preterm infants in the intervention and control groups in the incidence of safety indicators such as bradycardia,tachycardia,desaturation apnea,and neonatal necrotizing small bowel infection（P>0.05）.There was no statistically significant difference between the incidence of abdominal distension in preterm infants in the two groups（P>0.05）.Conclusion:The sensorial saturation method can effectively reduce the pain response and lower the pain score of preterm infants,and also help to alleviate the fluctuation amplitude of physiological indicators and behavioral indicators,and improve the comfort of preterm infants during blood collection.The sensory saturation method has the advantages of simple operation,safety and reliability relative to conventional care,and has certain application value,which is suitable for promotion and application in clinical operation.
