Ketoprofen for pain after hip and knee arthroplasty.
In a double-blind, randomized study, we have compared the effects of i.v. ketoprofen 200 mg followed by 12.5 mg h-1 over 13 h, with those of extradural morphine 4 mg in 32 patients after hip and knee arthroplasty. A visual analogue scale was used to score pain before analgesic administration (first complaint after operation), 1 h after and every 2 h subsequently. Pain reduction 1 h after the start of analgesia was mean 44% (SEM 17%) in the extradural morphine group and 54% (9%) in the ketoprofen group (ns). There were no significant differences between groups in pain scores, pain reduction and additional analgesia requirement (i.v. paracetamol). Naloxone 5 micrograms kg-1 h-1 was required for hypercapnia exceeding 6.0 kPa in three patients in the extradural morphine group (vs none in the ketoprofen group; ns). There were no differences between groups in side effects, except for urinary retention, which was more frequent in the extradural morphine group (P < 0.05). As there were few differences between i.v. ketoprofen and extradural morphine, we conclude that ketoprofen may be an efficient alternative to extradural morphine after hip and knee arthroplasty.
