Indications and contraindications for remifentanil PCA Remifentanil PCA may be offered to a woman in whom an epidural is contraindicated or refused, Call your doctor for medical advice about side effects. Remifentanil by bolus injection in healthy volunteers has been demonstrated to produce a dose-related increase in respiratory adverse effects, with oxygen desaturation occurring at bolus doses of 25 or 50 g, although not requiring intervention.17 Oxygen desaturation requiring oxygen supplementation has been demonstrated in the parturient receiving remifentanil PCA, but at a dose of 0.5 g kg1 and 2 min lockout the desaturation period was self-limiting.1011 Oxygen desaturation may occur in the non-medicated parturient or if she is breathing entonox during labour.18 Mild sedation was common in our study, but all women were alert to voice and none of the subjects requested withdrawal of PCA because of any side-effects experienced.

Remifentanil crosses the placenta and appears to be either rapidly metabolized or redistributed in the neonate. From a comparison of the CIs of summary estimates with a cut-off decrease of VAS 2, for the fixed model, there was a statistically significantly greater decrease in VAS than the cut-off. All subjects had a 20 min FHR trace every 2 h in the first and second stages of labour. Potentially serious side effects, which were observed frequently during remifentanil analgesia, may limit remifentanil's use in obstetrics. 4Department of Obstetrics and Gynaecology, Glan Clwyd Hospital, North Wales, UK, Oxford University Press is a department of the University of Oxford. Background. Ten fetal heart rate traces demonstrated changes in the first 20 min, but did not require intervention (95% CI, 1033.7%).

Remifentanil PCA provided adequate pain relief for 43 of the 50 women. The good neonatal outcome is consistent with previous studies, and Apgar scores have been demonstrated to be significantly higher following remifentanil PCA than after meperidine PCA.9 Fentanyl PCA in labour for those women with a contraindication to epidural analgesia has been shown to be associated with a 44% incidence of moderately depressed neonates.23. Smith MA, Morgan M. Remifentanil. This pattern of pain scoring in women in labour receiving remifentanil PCA has been demonstrated previously, and differs from the results obtained in women receiving meperidine as the pain scores continue to increase as labour progresses.9 Labour pain and its assessment is complex, but if one makes the assumption that the pain increases as labour progresses and a reduction in VAS pain score of 1 cm is clinically significant, then remifentanil at this dose provides analgesia during labour.16. It is only offered and available to women who have been advised not to have an epidural by an anaesthetist, because of medical conditions such as blood clotting disorders and some spinal abnormalities. Remifentanil does cross the placenta, and it may have similar effects on your baby that can occur with pethidine (such as reduced breathing rate and drowsiness). Remifentanil Dosage Guide + Max Dose, Adjustments - Drugs.com It has been suggested that remifentanil may be the opioid analgesia of choice for women in labour.

In our study, two women who requested an epidural required bupivacaine 0.25% for analgesia, as the low-dose epidural (bupivacaine 0.1% and fentanyl 2 g kg1) was inadequate for lower back pain because of a confirmed occipitoposterior fetal position. Remifentanil crosses the placenta and appears to be either rapidly metabolized or redistributed in the neonate.

DOI: 10.1093/BJA/AEI219 Corpus ID: 884327; Maternal and neonatal side-effects of remifentanil patient-controlled analgesia in labour. The results of this study indicate placental transfer of remifentanil following bolus administration during labour, but we have failed to demonstrate any adverse effects on the fetus or neonate. Since the first demonstration of the safety of remifentanil in obstetric analgesia in 1996, this has been repeatedly confirmed for both mother and newborn. This study evaluates the placental transfer of remifentanil and the neonatal effects when administered as an intravenous infusion.Methods. Raw data are presented for 412 h (n<17). We also aimed to assess the placental transfer of remifentanil.
