Obstetric analgesia: a comparison of patient-controlled meperidine, remifentanil, and fentanyl in labour

Douma MR et al. – The efficacy of meperidine, fentanyl, and remifentanil patient–controlled analgesia (PCA) for labour analgesia varied from mild to moderate. Remifentanil PCA provided better analgesia than meperidine and fentanyl PCA, but only during the first hour of treatment. In all groups, pain scores returned to pre–treatment values within 3 h after the initiation of treatment.
