Abstract
Objective To study the application value of different concentrations of ropivacaine combined with sufentanil for epidural stepwise labor analgesia.Methods From November 2021 to November 2022,60 parturients who planned to undergo epidural labor analgesia in Lianhua County Maternal and Child Health Hospital were selected as the research objects.They were divided into group A and group B according to the random number table method,with 30 parturients in each group.Group A was given 0.125％ropivacaine+0.45 μg/ml sufentanil for analgesia,and group B was given 0.075％ropivacaine+0.45 μg/ml sufentanil(orifice of uterus＜3 cm)combined with 0.125％ropivacaine+0.45 μg/ml sufentanil(orifice of uterus ≥3 cm)for analgesia.The pain visual analogue scale(VAS),blood pressure level[systolic blood pressure(SBP),diastolic blood pressure(DBP)],duration of labor(first stage of labor,second stage of labor,third stage of labor,total stage of labor),and lower limb muscle strength(Bromage score)were compared between the two groups.Results There was no significant difference in VAS scores between the two groups at orifice of uterus＜3 cm,orifice of uterus≥3 cm,when the orifice of uterus was fully opened and during delivery(P＞0.05).The levels of SBP and DBP at 5 min and 30 min after analgesia in the two groups were lower than those before analgesia,and those in group A were lower than those in group B(P＜0.05).The time of the first stage of labor and the total stage of labor in group B were shorter than those in group A(P＜0.05),but there was no significant difference in the time of the second stage of labor and the third stage of labor between the two groups(P＞0.05).The Bromage score of group B was better than that of group A(P＜0.05).Conclusion Different concentrations(0.075％+0.125％)of ropivacaine combined with sufentanil for epidural stepwise labor analgesia can ensure good analgesic effect,help to maintain maternal blood pressure stability,shorten labor time,and reduce maternal lower limb motor nerve block.关键词
