| Popis: | Following induction of epidural analgesia with 0.375% bupivacaine, 120 healthy parturients were randomly assigned in a double blind fashion to one of eight infusion groups. All received 8 ml.h-1 of 0.125% bupivacaine either alone (control group), or with alfentanil at 133, 266 or 400 micrograms.h-1 (groups A1-A3) or with diamorphine at 133, 266, 400 or 533 micrograms.h-1 (groups D1-D4). Significantly longer top-up intervals were achieved with the two highest doses of both alfentanil and diamorphine when compared with bupivacaine alone (p < 0.01), making the minimum effective doses 266 micrograms.h-1 of alfentanil and 400 micrograms.h-1 of diamorphine. Perineal analgesia was better in all the opioid groups compared with the control group (p < 0.05). The intensity of motor block was greater in the control group (p < 0.05). The incidence of pruritus did not differ between groups. The highest dose of diamorphine caused significantly more nausea. No significant neonatal side-effects were demonstrated. |
