Comparative study demonstrates improved maternal satisfaction and reduced pain in labor analgesia techniques.

The study aims to compare maternal satisfaction and breakthrough pain between two labor analgesia techniques: PIEB and CEI.
Cross-sectional study involving 192 term pregnant women receiving epidural labor analgesia.
Participants divided equally into PIEB (n=96) and CEI (n=96) groups.
Maternal satisfaction assessed using a 0-10 rating scale with statistical analysis for significance.
Maternal satisfaction scores were higher in the PIEB group (8.6 ± 0.9) compared to CEI (7.9 ± 1.2; p=0.001).
Breakthrough pain occurred less frequently in the PIEB group (p=0.011).
Total local anesthetic volume and fentanyl consumption were significantly lower in the PIEB group (p<0.05).

Sgouraki et al. (2026) studied this question.
