Nalbuphine: a candidate for treatment of women overwhelmed with sudden, intense labor pain?
On very rare occasions, women are overwhelmed with sudden, intense labor pain in the context of ultra-rapid late second stage of labor, especially when the head is crowning. The consequences may comprise serious pelvic floor damage for the mother and hypoxia for the fetus. Drugs like nalbuphine for immediate maternal analgesia and sedation would be helpful. This mixed opioid agonist-antagonist, that was used in obstetric anesthesia in the 1980s, acts quickly while side effects for the mother are minor. To better estimate possible complications for the fetus of a use shortly before birth, it is important to find out how quickly i.v. administered nalbuphine reaches fetal circulation. Therefore, we characterized the transplacental transfer of nalbuphine using an ex vivo model. ⋯ Only a small amount of nalbuphine is likely to reach the fetus during the first minutes after (i.v.) maternal administration. Nalbuphine might be a valuable candidate for clinical use in the i.v. analgesia and sedation of women overwhelmed with sudden labor pain in the context of ultra-rapid second stage of labor.

Randomized Controlled TrialFoley catheter versus cervical double balloon for labor induction: a prospective randomized study.
Cervical ripening by mechanical methods enhances labor induction success. We compared Cervical Ripening Double Balloon catheter (CRDB) to Foley catheter. ⋯ Bishop score increment by CRDB catheter is more effective than induction by Foley catheter in multiparas. CRDB catheter is associated with decreased time to delivery in both nulliparas and multiparas and a lower cesarean section rate in nulliparas. ClinicalTrials.gov Identifier: NCT00501033.
