Randomized Controlled Trial Clinical Trial
Clinical analgesic assay of repeated and single doses of heroin and hydromorphone.
A direct comparison of the analgesic activities of heroin and hydromorphone was carried out in cancer patients with postsurgical pain. Intramuscular doses of 5 and 10 mg of heroin were compared with 1 and 2 mg of hydromorphone in a randomized, double-blind, 4-point parallel group assay. Design innovations in the study provided that about half the patients would receive prior repeated doses of the same drug as the test medication, and half would receive the alternate medication. ⋯ Covariate analysis indicated that time since last analgesic was positively related to analgesia, and amount of prior opioid had a negative relationship. To a lesser extent, increase in patient age was associated with an increase in analgesic scores. Taking these covariates into account served to increase the sensitivity of the analysis.

Comparative Study Clinical Trial Controlled Clinical TrialAnalgesic efficacy of flurbiprofen as compared to acetaminophen and placebo after periodontal surgery.
The purpose of the present investigation was to compare the analgesic efficacy of flurbiprofen, a nonsteroidal anti-inflammatory drug, which is a phenyl propionic acid derivative, with acetaminophen and placebo in 63 adult outpatients with moderate to severe dental pain following periodontal surgery. After surgery was completed under local anesthesia, the patients received under double-blind conditions an envelope containing four tablets of either flurbiprofen 100 mg, acetaminophen 500 mg, or placebo and they were instructed to take one tablet every 6 hours when postoperative pain reached moderate to severe intensity. ⋯ Flurbiprofen was shown to possess an adequate analgesic effect superior to either placebo (P less than 0.005) or acetaminophen (P less than 0.01) in the parameters studied. Our results seem to further support earlier data obtained with the drug in dental patients with postoperative pain after the surgical removal of impacted third molars; therefore, it is concluded that flurbiprofen used as directed is a new alternative for the proper treatment of pain following periodontal surgery.

Randomized Controlled Trial Comparative Study Clinical Trial
[Influence of intrathecal morphine and buprenorphine on EEG and their analgesic effect].
This study was performed on fifty patients undergoing gynecological operations of lower abdomen. Their mean age and body weight were 43 +/- 5yrs and 55 +/- 8kg (mean +/- SD) respectively. All patients were given spinal anesthesia for surgery. ⋯ The result suggests that the earlier respiratory depression may be caused by large doses of intrathecal M. Postoperative analgesic effect was recognized remarkably in G-II, G-III and G-IV (P less than 0.01). The duration for pain relief was 6 hrs in G-II and 12 hrs in G-III and G-IV.(ABSTRACT TRUNCATED AT 250 WORDS)

In this randomized study, the efficacy of i.v. patient-controlled analgesia (PCA) was determined for the opioid piritramide (a pure mu-receptor agonist) and the antipyretic analgesic metamizole (Dipyrone) in three groups of patients following abdominal surgery. The doses of piritramide were 1.5 mg (40 patients) and 3 mg (40 patients) on demand. In addition, we studied the effect of 71 mg metamizole in combination with on-demand boluses of 1.5 mg piritramide in 40 patients. ⋯ The intensity of typical side effects of opioids and antipyretic analgesics (nausea, vomiting, lowering of respiratory frequency, sweating) was low and always easily controlled. The acceptance by patients, nurses, and physicians of PCA was high. PCA with on-demand intravenous injection of the combination of piritramide and metamizole improved the degree of analgesia and concomitantly reduced the opioid dose.
