Segmental epidural analgesia for labor and delivery

Area of Science:

• Obstetrics and Gynecology
• Anesthesiology
• Pain Management

Background:

• Epidural analgesia is a common method for pain relief during labor.
• Evaluating different anesthetic agents and delivery methods for labor pain is crucial for optimizing maternal and fetal outcomes.

Purpose of the Study:

• To evaluate the efficacy and safety of segmental epidural analgesia during labor.
• To compare the effects of 2-Chloroprocaine and lidocaine for second-stage labor pain relief.

Main Methods:

• A study involving 124 full-term patients (36 nulliparous, 88 multiparous).
• First stage: Bupivacaine (0.25%).
• Second stage: Group I - 2-Chloroprocaine via catheter; Group II - 1% Lidocaine perineal infiltrate.

Main Results:

• Satisfactory pain relief in 92% of patients during the first stage.
• No significant changes in maternal blood pressure, motor power, uterine contractions, or fetal presentation with effective analgesia.
• Second stage: 91% required low forceps with 2-Chloroprocaine vs. 44% with lidocaine.
• Excellent fetal outcomes with 1-minute Apgar scores never below 7.

Conclusions:

• Segmental epidural analgesia is effective for labor pain management.
• 2-Chloroprocaine for second-stage pain management increases the likelihood of instrumental delivery compared to lidocaine infiltration.
• The evaluated methods demonstrated good maternal and fetal safety profiles.
