Randomized Controlled Trial Comparative Study Clinical TrialComparison of the analgesic dose-effect relationships of nefopam and oxycodone in postoperative pain.
The analgesic dose-effect relationship of nefopam was compared in a double-blind randomised trial with that of oxycodone in immediate postoperative pain. Nefopam 15 mg or oxycodone 4 mg was given every 10 min i.v. (maximum six times) to patients in pain after upper abdominal surgery until their wound pain (scored 0-3) disappeared. The mean pain intensity (PI), initially 2.2 in both groups, descreased by approximately the same extent for up to two doses in both groups (to 1.5 after nefopam 30 mg and to 1.1 after oxycodone 8 mg). ⋯ In the nefopam group, 12 patients (75%) needed further pain relief after the maximal dosage (6 x 15 mg). In these patients, oxycodone (maximally 16 mg) gave satisfactory analgesia. Drowsiness and a decrease in the respiratory rate were the principal side-effects of oxycodone, whereas tachycardia, restlessness, sweating and nausea were more frequent after nefopam.

Between July, 1974 and February, 1979, 109 adolescent girls, ranging in age from 10 1/2 to 19 yr. with unexplained chronic pelvic pain, underwent diagnostic laparoscopy. Endometriosis was the most common finding occurring in 49 patients (45%), followed by postoperative adhesions in 17 patients (16%) and congenital abnormalities of the uterus in 10 patients (9%). ⋯ Analysis of the presenting symptoms and physical findings revealed in most instances that the presence of significant pelvic pathology as a cause of the chronic pelvic pain was predictable and had been previously misdiagnosed. Intraoperative and postoperative management of the major problems encountered stress the importance of conservative surgery and the need for long-term follow-up.
