Randomized Controlled Trial Multicenter Study Clinical TrialTreatment of menstruation-associated migraine with the nonprescription combination of acetaminophen, aspirin, and caffeine: results from three randomized, placebo-controlled studies.
This retrospective study sought to examine the benefits of the nonprescription combination of acetaminophen, aspirin, and caffeine (AAC; Excedrin Migraine, Bristol-Myers Squibb Company, New York, New York) for the treatment of menstruation-associated migraine compared with migraine not associated with menses. Data were derived from 3 double-masked, randomized, placebo-controlled, single-dose trials enrolling subjects who met the International Headache Society's diagnostic criteria for migraine with or without aura. Subjects with incapacitating disability (attacks requiring bed rest >50% of the time) and those who usually experienced vomiting > or =20% of the time were excluded. ⋯ The proportion of subjects who had 1 or more adverse experiences was significantly higher among those receiving AAC than among those receiving placebo (menstruation-associated migraine: AAC 26.4%, placebo 12.6%, P = 0.025; nonmenstruation-associated migraine: AAC 18.6%, placebo 11.4%, P = 0.005). Adverse experiences were similar in type and severity to those previously associated with single doses of acetaminophen, aspirin, or caffeine. Thus the nonprescription combination of AAC was highly effective in treating the pain, disability, and associated symptoms of both menstruation-associated migraine and migraine not associated with menses.

Randomized Controlled Trial Multicenter Study Clinical TrialA double-blinded evaluation of propacetamol versus ketorolac in combination with patient-controlled analgesia morphine: analgesic efficacy and tolerability after gynecologic surgery.
We assessed the relative morphine consumption in a combined analgesic regimen (on-demand morphine plus the nonopioids propacetamol or ketorolac) after gynecologic surgery. Two hundred women randomly received two i.v. doses of propacetamol 2 g or ketorolac 30 mg in a double-blinded, double-dummy trial. Patients were monitored for 12 h, and the following efficacy variables were assessed: total dose of morphine, pain intensity, and global efficacy. Safety and tolerability were evaluated by the occurrence of adverse events, especially the presence and intensity of gastrointestinal symptoms. Hemostatic variables were measured 30 and 60 min after the first infusion; arterial blood pressure, heart and respiratory rates, sedation scores, and renal and hepatic function were also assessed. Total morphine requirements were not significantly different between the propacetamol (10.6 +/- 4.8 mg) and ketorolac (10.2 +/- 4.4 mg) groups. The evolution of pain intensity and the global efficacy also showed similar patterns in the two groups: 70.2% of patients in the propacetamol group rated the efficacy as "good/ excellent" compared with 68.2% in the ketorolac group. There were no clinically significant changes in vital signs or laboratory values and no observed differences between the two groups, although ketorolac slightly, but not significantly, prolonged the bleeding time. Epigastric pain was present in 9% and 15% of patients receiving propacetamol and ketorolac, respectively. There were two adverse events in the propacetamol group and four in the ketorolac group. Propacetamol demonstrates an efficacy similar to that of ketorolac and has an excellent tolerability after gynecologic surgery. ⋯ Propacetamol and ketorolac, combined with patient-controlled analgesia morphine, show similar analgesic efficacy after gynecologic surgery. Morphine consumption and pain scores were comparable in the two studied groups. Propacetamol is as effective as ketorolac and has an excellent tolerability after gynecologic surgery.

Randomized Controlled Trial Clinical Trial
Postoperative behavioral outcomes in children: effects of sedative premedication.
Although multiple studies document the effect of sedative premedication on preoperative anxiety in children, there is a paucity of data regarding its effect on postoperative behavioral outcomes. ⋯ Children who are premedicated with midazolam before surgery have fewer negative behavioral changes during the first postoperative week.

Randomized Controlled Trial Clinical TrialParacetamol 1 g given rectally at the end of minor gynaecological surgery is not efficacious in reducing postoperative pain.
We studied the analgesic effects of 1 g paracetamol given rectally at the end of surgery in a prospective, randomised, double-blind study. ⋯ The routine use of 1 g paracetamol given rectally at the end of surgery after termination of pregnancy seems not to be justified.

Randomized Controlled Trial Comparative Study Clinical TrialThe analgesic effect of preoperative administration of propacetamol, tenoxicam or a mixture of both in arthroscopic, outpatient knee surgery.
A prospective, randomized, double-blind, placebo-controlled, comparative study was undertaken to assess the efficacy of the preemptive use of propacetamol, tenoxicam or the combination of both in arthroscopic, outpatient surgery of the knee. One hundred patients aged 18 to 65 years, ASA 1-2, scheduled for arthroscopy were randomized to receive propacetamol 30 mg/kg i.v. (repeated after 6 hours), tenoxicam 0.5 mg/kg i.v. (max. 40 mg), the combination of both or placebo one hour prior to a standard anesthetic. There were no differences with regard to total dose opioid consumption, sedation scores and side effects in the four groups.
