Randomized Controlled Trial Comparative Study Clinical Trial
A comparison of epidural diamorphine with intravenous patient-controlled analgesia using the Baxter infusor following caesarean section.
In a randomised study of analgesia following Caesarean section, we compared the efficacy and side effects of on-demand epidural diamorphine 2.5 mg with intravenous patient-controlled analgesia using diamorphine from the Baxter infusor system. Pain scores fell more rapidly in the epidural group, but by the fourth hour, and thereafter, both techniques had a similar analgesic effect. ⋯ This reached statistical significance (p < 0.05) between 9-24 h. Overall satisfaction scores (0-100) were high, but the patient-controlled analgesia group scored significantly higher: mean 85.5 (SD 12.2) compared to mean 77.0 (SD 11.7) in the epidural group.
