Randomized Controlled Trial Multicenter Study Comparative Study Clinical Trial
Continuous epidural infusion of ropivacaine for postoperative analgesia after major abdominal surgery: comparative study with i.v. PCA morphine.
We have compared the quality of three regimens of postoperative analgesia (continuous epidural administration of ropivacaine (Ropi. group), epidural ropivacaine and patient-controlled analgesia (PCA) with i.v. morphine (Ropi. + PCA group) and PCA morphine alone (PCA group)) during the first postoperative 24 h in a multicentre, randomized, prospective study. Postoperative analgesia was studied in 130 patients after major abdominal surgery performed under general anaesthesia. The ropivacaine groups received 20 ml of epidural bolus ropivacaine 2 mg ml-1 via the epidural route at the end of surgery, followed by continuous infusion of 10 ml h-1 for 24 h. ⋯ Morphine consumption was higher in the PCA group (P < 0.05) than in the two ropivacaine groups. The quality of pain relief was rated as good or excellent in 79-85% of patients in the three groups. The percentage of patients without motor block increased between 4 and 24 h from 61% to 89% in the Ropi. group, and from 51% to 71% in the Ropi. + PCA group.
