Key result
0.0625% bupivacaine with sufentanil provided satisfactory epidural analgesia and is a preferable alternative to 0.1% bupivacaine, despite requiring a second dose sooner (62.0 vs 84.0 minutes, p=0.01).
Why the study?
Does 0.0625% bupivacaine with 0.5 μg/mL sufentanil provide comparable analgesia to 0.1% bupivacaine with 0.5 μg/mL sufentanil for epidural obstetric analgesia?

Absolute Event Rate: 62% vs 84%
p-value: p=0.01
The combination of 0.0625% bupivacaine with 0.5 μg/mL sufentanil provides satisfactory epidural analgesia (VAS<4) with fewer hemodynamic side effects compared to 0.1% bupivacaine with 0.5 μg/mL sufentanil, despite slightly lower satisfaction scores.
Çakırca et al. (2013) conducted an RCT in Labor pain (n=30). 0.0625% bupivacaine with 0.5 μg/mL sufentanil vs. 0.1% bupivacaine with 0.5 μg/mL sufentanil was evaluated on Time to second analgesic dose (minutes) (p=0.01). 0.0625% bupivacaine with sufentanil provided satisfactory epidural analgesia and is a preferable alternative to 0.1% bupivacaine, despite requiring a second dose sooner (62.0 vs 84.0 minutes, p=0.01).
