Study on application of program-controlled epidural space pulse injection technique in painless labor
Objective To analyze application value of programmed intermittent epidural bolus(PIEB)in labor analgesi-a.Methods A total of 106 obstetric women who underwent painless labor and were admitted to Zhengzhou Maternal and Child Health Hospital from January 2021 to December 2021 were selected,all of whom received sufentanil combined with low-concentration ropivacaine for analgesia.According to random number table method they were divided into two groups,each group 53 cases.The control group received continuous epidural infusion for analgesia,and the observation group received program-controlled epidural space pulse injection.Delivery outcomes,pain at different times,adverse reactions,stress indi-ces[serum aldosterone(ALD),norepinephrine(NA)]and neonatal conditions were compared between two groups.Results The group observation rate of natural delivery was 88.68％higher than that of control group 50.94％,vaginal mid-wifery and cesarean section rate of observation group were 5.67％,both lower than taht of control group(P＜0.05).There was no statistical difference in VAS scores before analgesia between 2 groups(P＞0.05).The VAS scores of observation in group 30 min after treatment,at full uterine opening and fetal delivery were(1.57±0.31),(1.71±0.26)and(1.77±0.49),respectively,all lower than control group(P＜0.05).The nausea,vomiting,pruritus,hypotension and urinary retention of adverse reactions incidence in observation group was 5.00％,lower than control group and the difference was statistically sig-nificant(30.00％,P＜0.05).The levels of aldosterone and norepinephrine in 2 groups were compared when the uterine o-pening was 3cm(P＞0.05).The levels of aldosterone and norepinephrine at delivery in the observation group were(111.76±21.46)ng/L and(390.67±49.76)ng/L,which were lower than those in the control group(P＜0.05).The 1-mi-nute Apgar score and 5-minute Apgar score in the observation group were(9.49±0.28)and(9.81±0.11),which were higher than those in the control group(P＜0.05).Conclusion Program-controlled epidural space pulse injection tech-nique has a remarkable effect in labor analgesia,whhich can effectively relieve the pain of patients,reduce the adverse reac-tions of patients,and is worthy of clinical application.
