Analgesic efficacy of remifentanil patient-controlled analgesia versus combined spinal-epidural technique in multiparous women during labour.

In multiparas, CSEA provided superior analgesia and satisfaction than RPCA. Nevertheless, RPCA provided a satisfactory experience, suggesting it could be used when neuraxial analgesia is not available, preferred, or contraindicated. In that case, constant presence of midwife is mandatory for management of clinically significant hypoventilation.
