Effect of ropivacaine and sufentanil in epidural labor analgesia.

OBJECTIVE
To investigate the application value of ropivacaine combined with sufentanil for epidural labor analgesia in painless labor.


METHODS
A total of 157 cases of pregnant female received painless labor in our hospital from January 2019 to December 2020 were randomly divided into observation group (n=81 cases) and control group (n=76 cases). The subjects in the observation group received 0.1% ropivacaine combined with sufentanil (0.25 μg/ml) 10 ml and added into the painless delivery pump, and the control group received 0.1% ropivacaine 10 ml into the painless delivery pump. The analgesic effect, lactation function, delivery outcomes and the labor course of the two groups were compared.


RESULTS
In the active stage of labor, the time of first labor process was shorter compared with the control group, those in the observation group were more active than the control group (P<0.05). The lactation initiation time of the observation group was shorter than that of the control group, and the effective rate of lactation was higher than that of the control group (P<0.05). The Visual analogue scale (VAS) score at 5 min, 30 min, 60 min, and 90 min after analgesia were improved in the observation group, the analgesic effect of ropivacaine combined with sufentanil for epidural labor analgesia was prior to ropivacaine alone. There were significant differences in the rates of conversion to cesarean section and usage rate of forceps between the two groups (P<0.05), while there had no significant differences in lateral episiotomy rate and Apgar scores at 1 and 5 min after birth between the two groups (P>0.05).


CONCLUSION
Ropivacaine combined with sufentanil for epidural labor analgesia in painless labor can effectively relieve labor pain, improve lactation function, active the first stage of labor, shorten the time of labor, reduce the incidence of cesarean section and ensure the safety of mother and infant.
