Application of Different Angle Puncture Methods Combined with Quarter Positioning Method in Neonatal Radial Artery Blood Sampling
Objective:To evaluate the effectiveness and safety of different angle puncture methods combined with quarter positioning method in neonatal radial artery blood sampling.Method:A total of 176 newborns admitted to the Neonatology Department of Shengze Hospital,Jiangsu Province from October 2022 to October 2023 were selected as research samples.According to the random number table method,they were divided into two group,72 cases were assigned to the control group using the traditional puncture method,and 104 cases were assigned to the observation group using different angle puncture methods combined with quarter positioning method.The success rate of blood sampling,blood sampling time,subcutaneous bleeding,pain scores[neonatal facial coding system(NFCS),neonatal infant pain scale(NIPS)],onset time and duration time of painful facial expressions and crying,and vital signs[heart rate,respiratory rate,transcutaneous oxygen saturation]were observed between the two groups groups.Result:The success rate of blood sampling in the observation group was higher than that in the control group,the blood sampling time was shorter,and the incidence of subcutaneous hemorrhage was lower than that in the control group,the differences were statistically significant(P＜0.05).The NFCS scores and NIPS scores at the end of puncture in the two groups were lower than those at the puncture,NFCS scores and NIPS score at the end of puncture in observation group were lower than those in the control group,and the differences were statistically significant(P＜0.05).The onset time of painful facial expressions and crying in observation group were later than those in control group,and the duration time of painful facial expressions and crying in observation group were shorter than those in control group,the differences were statistically significant(P＜0.05).At the end of puncture,the heart rate and respiratory rate in the two groups were higher than those at the time of puncture,the heart rate and respiratory rate of the observation group were lower than those of the control group,and the transcutaneous oxygen saturation was higher than that of the control group,the differences were statistically significant(P＜0.05).Conclusion:The application of different angle puncture methods combined with quarter positioning method in neonatal radial artery blood sampling can significantly increases the success rate of blood sampling,reduces the incidence of complications,and is beneficial in maintaining stable vital signs,proving its effectiveness and safety in clinical application.
