About

Women requiring epidural labor analgesia were randomized into two groups, one with the local anesthetic chloroprocaine and the other with ropivacaine. The primary outcome was to observe the analgesic scores of the two groups of drugs as well as adverse reactions.

Full description

Mothers who met the study criteria vertebrae were included and then divided into two groups. Labor analgesia was provided by epidural anesthesia with a low concentration of local anesthetic (chloroprocaine or ropivacaine) combined with sufentanil. Data related to labor analgesia such as pain scores, motor tissue scores, and body temperature were collected and statistically analyzed to compare the efficacy and adverse effects of the two local anesthetics and to draw conclusions.
