Extradural Morphine And Pain Relief Following Episiotomy
BRITISH JOURNAL OF ANAESTHESIA(1984)
摘要
One hundred and fifty obstetric patients, who had received intrapartum extradural analgesia with bupivacaine, and had required episiotomy, were given a final postpartum injection of preservative-free morphine in saline, or saline alone, on a double-blind basis. The degree of perineal analgesia was assessed by linear analogue scale at intervals up to 36 h, and oral analgesic requirements were recorded. A significant degree of analgesia was obtained for up to 12 h with morphine 2 mg, compared with saline. Increasing the dose to 4 mg increased the occurrence of side-effects, and was associated with less marked analgesia.
