5. Conclusion
ANESTHETIC COMPLICATIONS
In summary, our findings indicate there is no difference in the anesthetic effect between DPEA with the drug injected after catheterization and EA during labor analgesia. The analgesic effect of DPEA is better than that of EA when the epidural puncture needle is used to inject the experimental dose of the drug. However, when DPE was used for labor analgesia, the incidence of puncture and anesthetic complications significantly increases.
