Randomized Controlled Trial Comparative Study Clinical TrialKetorolac tromethamine as compared with morphine sulfate for treatment of postoperative pain.
Ketorolac tromethamine, a nonnarcotic, prostaglandin synthesis-inhibiting analgesic, was compared with morphine sulfate for relief of moderate to severe postoperative pain. The 155 patient participants received single intramuscular doses of either ketorolac, 10, 30, or 90 mg, or morphine, 6 or 12 mg, administered in a double-blind, randomized fashion. Pain scores (verbal and visual analog) were recorded at baseline and assessed at 30 minutes and then hourly to 6 hours. ⋯ There were no serious side effects reported. The only side effect reported in more than 3% of patients was 8% somnolence with morphine. This study shows ketorolac to be a safe and effective analgesic for relief of postoperative pain.

Randomized Controlled Trial Comparative Study Clinical TrialCodeine and aspirin analgesia in postpartum uterine cramps: qualitative aspects of quantitative assessments.
The analgesic response to codeine of patients with postpartum uterine-cramp pain has recently met with controversy. To readdress this question, we conducted a new study comparing codeine sulfate, 60 mg (N = 32) and 120 mg (N = 31), with aspirin, 650 mg (N = 34), and placebo (N = 32) in hospitalized women with moderate or severe postpartum uterine cramps treated with single oral doses in a parallel, stratified, randomized, double-blind trial. Subjective reports were used as indices of response, and patients rated pain intensity, pain relief, and side effects at periodic, uniformly conducted interviews for 6 hr. ⋯ In contrast, in a subset of patients with mixed episiotomy-uterine pain (N = 73), 120 mg codeine showed good separation from placebo and compared favorably with aspirin. Codeine, 60 mg, showed a similar trend, and there was a strong suggestion of dose-dependent analgesia. Side effects were not remarkable except for dizziness and drowsiness after 120 mg codeine in all sets and subsets of patients.(ABSTRACT TRUNCATED AT 250 WORDS)

Randomized Controlled Trial Clinical TrialNonpharmacologic intervention in acute alcohol withdrawal.
The importance of nonpharmacologic and pharmacologic interventions in the treatment of alcohol withdrawal is not known. A randomized, double-blind, placebo-controlled trial was conducted with 41 patients in alcohol withdrawal in an emergency department. The patients received either supportive care (10 min of standardized assessments, reassurance, reality orientation, and nursing care an hour) with three doses of sublingual lorazepam 2 mg every 2 hr (21 patients, drug group) or supportive care with three doses of sublingual placebo every 2 hr (20 patients, no-drug group). ⋯ The rate of improvement of CIWA-A scores over the first 2 hr after drug was slightly faster in patients receiving lorazepam than in the control group. CIWA-A scores were the same during follow-up. These results indicate that most outpatients in mild to moderate alcohol withdrawal without medical complications improve without drug therapy in the emergency department setting.

Randomized Controlled Trial Clinical TrialMetkephamid and meperidine analgesia after episiotomy.
Metkephamid is an analog of methionine enkephalin. The efficacy, safety, and time course of analgesia with 70 or 140 mg metkephamid were compared with those of 100 mg meperidine and placebo in 59 hospitalized women with severe postpartum episiotomy pain. There were two separate trials with single intramuscular doses and identical designs, including parallel groups, randomized blocks, and double-blind conditions. ⋯ Although dizziness was experienced with meperidine, the two metkephamid doses induced other side effects, including sensation of heavy limbs, dry mouth, eye redness, and nasal stuffiness. None were distressing. Our results suggest that 140 mg metkephamid compares favorably with 100 mg meperidine for analgesia after episiotomy, but it induces minor side effects more frequently.

Randomized Controlled Trial Comparative Study Clinical TrialNefopam and propoxyphene in episiotomy pain.
To evaluate relative efficacy, safety, and time course of analgesia, nefopam (45 and 90 mg), a new centrally acting nonnarcotic analgesic, was compared with propoxyphene (65 mg) and placebo in a single oral dose, parallel, stratified, randomized, double-blind trial with 100 hospitalized postpartum women with medium or severe episiotomy pain. Using subjective reports as indices of response, patients rated pain intensity and side effects at periodic interviews for 6 hr. ⋯ Side effects included mild dizziness and hypothermia after nefopam and mild elevation of diastolic arterial pressure after nefopam and propoxyphene. Our results suggest that 45- and 90-mg doses of nefopam induced more analgesia than 65 mg propoxyphene in the relief of episiotomy pain.
