Randomized Controlled Trial Clinical Trial
Effect of paracetamol (acetaminophen) on body temperature in acute ischemic stroke: a double-blind, randomized phase II clinical trial.
Body temperature is a strong predictor of outcome in acute stroke. However, it is unknown whether antipyretic treatment leads to early and clinically worthwhile reduction of body temperature in patients with acute stroke, especially when they have no fever. The main purpose of this trial was to study whether early treatment of acute ischemic stroke patients with acetaminophen (paracetamol) reduces body temperature. ⋯ Treatment with a daily dose of 6000 mg acetaminophen may result in a small, but potentially beneficial, decrease in body temperature shortly after ischemic stroke, even in normothermic and subfebrile patients. Further studies should determine whether this effect is reproducible and whether early reduction of body temperature leads to improved outcome.

Randomized Controlled Trial Comparative Study Clinical Trial
Comparison of fever treatments in the critically ill: a pilot study.
Fever in critically ill patients is often treated with antipyretics or physical cooling methods. Although fever is a host defense response that may benefit some critically ill patients, others may not tolerate the cardiovascular demands associated with fever. ⋯ Although the study included only 14 subjects, the findings will provide information for future studies in febrile critically ill patients.

Randomized Controlled Trial Comparative Study Clinical Trial
Analgesic efficacy and safety of nefopam vs. propacetamol following hepatic resection.
In order to compare the morphine-sparing effect, analgesic efficacy and tolerance of nefopam and propacetamol given at their highest recommended doses, 120 patients undergoing elective hepatic resection were randomly assigned to receive postoperative intravenous patient-controlled analgesia with morphine alone, or in combination with nefopam (20 mg.4 h-1) or propacetamol (2 g.6 h-1). Compared with the control group (43 [7-92] mg), median [range] cumulative morphine consumption for 24 h after the study started was halved in the nefopam group (21 [3-78] mg, p <0.001) and 20% lower in the propacetamol group (35 [6-84] mg, p = 0.15). ⋯ Adverse effects were comparable in the three groups, except for significantly more nausea in the control group (39% vs. 17 and 26% in the nefopam and propacetamol groups, respectively) and more sweating in the nefopam group (17% vs. 0 and 3% in the control and propacetamol groups, respectively). Overall patient satisfaction was better (p < 0.001) in patients given nefopam (97%) than those receiving morphine alone (82%) or propacetamol (74%).

Randomized Controlled Trial Multicenter Study Comparative Study Clinical TrialAntipyretic effects of dipyrone versus ibuprofen versus acetaminophen in children: results of a multinational, randomized, modified double-blind study.
This study compared the antipyretic effectiveness of acetaminophen, ibuprofen, and dipyrone in young children with fever. The results were based on a modified double-blind, randomized, multinational trial that evaluated 628 febrile children, aged 6 months to 6 years. ⋯ After 4 to 6 hours, mean temperature in the dipyrone group was significantly lower than the other groups, demonstrating longer temperature normalization with dipyrone. All three drugs showed comparable tolerability profiles.

Randomized Controlled Trial Clinical TrialIntravenous administration of propacetamol reduces morphine consumption after spinal fusion surgery.
We sought to determine the analgesic efficacy, opioid-sparing effects, and tolerability of propacetamol, an injectable prodrug of acetaminophen, in combination with morphine administered by patient-controlled analgesia (PCA) after spinal fusion surgery. Forty-two patients undergoing spinal stabilization surgery were randomized into two groups, which were given either an IV placebo or an IV injection of 2 g propacetamol every 6 h for 3 days after surgery. The postoperative opioid analgesic requirement was assessed with a PCA device used to self-administer morphine. ⋯ The pain scores were significantly lower in the Propacetamol group measured at two intervals of the study, although visual analog scale pain intensity scores were smaller than 3 in both groups. Most patients in the Placebo group obtained a greater degree of sedation on postoperative Day 3 (P < 0.05). This study demonstrates the usefulness of propacetamol as an adjunct to PCA morphine in the treatment of postoperative pain after spinal fusion.
