Summary

This completed study looked at 9,000 women with a BMI of 40 or higher to find out which type of epidural works best for labor pain. Researchers compared three techniques: combined spinal-epidural, standard epidural, and dural puncture epidural. The goal is to help doctors choose the most effective pain relief for heavier mothers.

What could go wrong
