Randomized Controlled Trial Comparative Study Clinical Trial
Perioperative effects of oral ketorolac and acetaminophen in children undergoing bilateral myringotomy.
Prophylactic administration of analgesics before surgery can decrease the intraoperative anaesthetic requirement and decrease pain during the early postoperative period. In a double-blind, placebo-controlled study involving 90 healthy ASA physical status I or II children undergoing bilateral myringotomy, we compared the postoperative analgesic effects of oral acetaminophen and ketorolac, when administered 30 min before induction of anaesthesia. Patients were randomized to receive saline (0.1 ml.kg-1), acetaminophen (10 mg.kg-1) or ketorolac (1 mg.kg-1) diluted in cherry syrup to a total volume of 5 ml. ⋯ The ketorolac group had lower postoperative pain scores and required less frequent analgesic therapy in the early postoperative period compared with the acetaminophen and placebo groups. In contrast, there were no differences in pain scores or analgesic requirements between the acetaminophen and the placebo groups. We conclude that the preoperative administration of oral ketorolac, but not acetaminophen, provided better postoperative pain control than placebo in children undergoing bilateral myringotomy.

Randomized Controlled Trial Comparative Study Clinical Trial
A multiple dose comparison of combinations of ibuprofen and codeine and paracetamol, codeine and caffeine after third molar surgery.
In a randomised, double-blind, double-dummy, multiple dose, crossover study in 30 patients we compared an ibuprofen/codeine combination (400 mg ibuprofen/25.6 mg codeine phosphate) with a paracetamol/codeine/caffeine combination (1 g paracetamol/16 mg codeine phosphate/60 mg caffeine) for pain relief over 6 days after two-stage bilateral lower third molar removal. The ibuprofen combination produced significantly greater analgesia than the paracetamol combination, both on single-dose analysis of the first and second days and on multiple-dose measures for days 1, 2, 3 and 4. ⋯ This trial design (crossover with multiple dosing in outpatients) is a sensitive way of testing for analgesia, and is potentially more predictive of adverse effect problems than single-dose studies. It confirms that multiple dosing may show increased efficacy.

Comparative StudyReaction time in cancer patients receiving peripherally acting analgesics alone or in combination with opioids.
Continuous Reaction Time (CRT) was measured in cancer patients receiving peripherally acting analgesics either alone (n = 16) or in combination with opioids (n = 16). Comparison was performed matching the patients from each group for age and performance status. Statistically significant prolongations of CRT and higher sedation scores were seen in the opioid group, while performance status did not have any influence on CRT.

Acetaminophen overdose as a suicidal gesture: a survey of adolescents' knowledge of its potential for toxicity.
Acetaminophen is a popular nonprescription analgesic that is often taken in overdose by adolescents during suicidal gestures. The authors hypothesized that most adolescents are naive about the toxic and lethal potential of acetaminophen in overdose. ⋯ Moreover, 17% of the sample did not believe one could ingest enough acetaminophen to cause death. The lack of knowledge about acetaminophen's potential dangerousness, its widespread availability, and an absence of early symptoms of hepatotoxicity make this medication highly dangerous to those adolescents who take it in overdose during parasuicidal behavior.
