Background: Epidural analgesia in Obstetrics is nowadays the gold standard for pain relief in labour, but in some cases is contraindicated or the analgesia is incomplete. Remifentanil is a strong, ultra-short-acting and fast onset opioid that timing very well with the dynamic of the labour. The coordination between the beginning of the uterus contraction and the drug administration with the PCA device makes this technique could be considered as election for pain relieve in labour and not only as an alternative to epidural. Objective: This study aims to assess the efficacy and safety of the intravenous remifentanil in labour and the maternal satisfaction. Materials and methods: Descriptive and prospective study based on the review of the dates recorded by the investigators during the labour where it´s registered the pain along the dilatation and the expulsive before and after applied the remifentanil PCA, and the complications and the incidents of secondary effects as well. At the same time it´s made an inquiry about maternal satisfaction about the technique received and their personal experience. Results: 32 cases have been recorded in total during the study period (6 months). All patients have been presented a reduction of the pain displayed by a reduction of the EVA in 5.9 points in the first minutes, 4.6 in completed, and 3.4 in the expulsive. The maternal satisfaction has been high, and 90 % of parturient would be repeated the technique. Conclusions: Remifentanil PCA has been seemed effective and safe as analgesic in Obstetrics. It´s for that remifentanil PCA has been had a great acceptation within midwifes, gynaecologist and anaesthetist in our hospital, currently it is been offered as first option as epidural, depending on the patient, obstetrician and anaesthetist opinion.
