Current evidence does not support FPBs as replacements for neuraxial analgesia. Their use should be restricted to highly selected cases where neuraxial techniques are not feasible. Importantly, there is no predefined formula for managing labor pain-analgesic strategies must be individualized according to clinical context, patient preference, and available resources. High-quality prospective studies are necessary to clarify the role of FPBs in labor.
