AbstractObjective: To investigate the curative effect of remifentanil on analgesia in newborns.Patients and methods: One hundred and twenty full-term puerperae from January 2013 to December 2013 were selected and randomly divided into three groups: remifentanil patient-controlled intravenous labor analgesia group (Group A, n = 40), patient-controlled epidural analgesia (PCEA) group (Group B, n = 40), and spontaneous labor group (Group C, n = 40). General conditions, visual analogue scale (VAS) score, labor stage, bleeding, delivery mode, neonatal asphyxia rate, oxyhemoglobin saturation in puerpera, and umbilical arterial blood gas analysis indexes of the fetus were measured. In addition, complications and adverse reactions were recorded.Results: VAS scores in Group A and B were significantly lower than that in Group C at each time point after analgesic intervention (p < .05), without differences at 30 min and 1 h after analgesia between Group A and B (p > .05). However, VAS scores in Group A were significantly higher than those in Group B at the full opening of the uterine orifice and fetal delivery (p < .05). The active phases in the first stage of labor in Group A and B were significantly shorter than that in Group C (p <.05). There were no significant differences in general conditions, VAS score before analgesia, the second and third stages of labor, delivery mode, bleeding, neonatal asphyxia rate, oxyhemoglobin saturation, pH value, partial pressure of oxygen (PO2), and partial pressure of carbon dioxide (PCO2) among three groups (p > .05).Conclusions: Remifentanil intravenous labor analgesia is not superior to PCEA, but does not increase adverse effects, suggesting it might be a supplementary method of PCEA.
