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.

Randomized Controlled Trial Comparative Study Clinical Trial
Antipyretic efficacy of ibuprofen vs acetaminophen.
To compare the antipyretic efficacy of ibuprofen, placebo, and acetaminophen. ⋯ Ibuprofen is a potent antipyretic agent and is a safe alternative for the selected febrile child who may benefit from antipyretic medication but who either cannot take or does not achieve satisfactory antipyresis with acetaminophen.

Randomized Controlled Trial Comparative Study Clinical Trial
Comparison of multidose ibuprofen and acetaminophen therapy in febrile children.
To determine whether febrile children receiving 2.5-, 5-, or 10-mg/kg ibuprofen therapy via a liquid or 15-mg/kg acetaminophen therapy via an elixir every 6 hours for 24 to 48 hours show equivalent fever reduction or suffer adverse effects of the drug administered. ⋯ In 61 of the 64 evaluable patients, treatments were effective and well tolerated during the entire study. While the rates of temperature reduction and maximal reduction of fever after administration of the initial dose were equal for patients receiving 10-mg/kg ibuprofen therapy and 15-mg/kg acetaminophen therapy, and both regimens were more effective than smaller doses of ibuprofen in reducing fever, after the second dose (and continuing to the end of the study) there were no statistically significant differences in temperature response among the treatment groups. Six children were withdrawn from the study, two because of dosing errors, three because of hypothermia (temperature of less than 35.6 degrees C; all three patients were in the acetaminophen group), and one because of gastrointestinal distress (this child was in the group receiving 2.5-mg/kg ibuprofen therapy). No other significant symptoms or adverse laboratory or physical findings were noted. While further confirmatory studies are needed, ibuprofen liquid (10 mg/kg) and acetaminophen elixir (15 mg/kg) administered every 6 hours for 24 to 48 hours appeared to be most effective in reducing fever. These two regimens were equally effective and equally tolerated in febrile children. Lower ibuprofen doses (2.5 and 5 mg/kg) were less effective than acetaminophen and 10-mg/kg ibuprofen therapy after the initial dose but were at least equally effective as these two higher-dose regimens thereafter.

Randomized Controlled Trial Clinical Trial
Optimal patient position for transport and initial management of toxic ingestions.
Many factors influence the rate of gastric emptying and therefore the rate of drug absorption in the orally poisoned patient. Limited studies have evaluated the effect of body position on the rate of gastric emptying of radiographically marked foods and contrast media, but effects on drug absorption have not been studied previously. Our hypothesis was that body position would have an effect on the rate of drug absorption in an oral overdose model. ⋯ Initial drug absorption as determined by two-hour AUC was lowest in the left lateral decubitus position. Although the difference between the left lateral decubitus and supine positions did not reach statistical significance, both left lateral decubitus and supine were significantly lower than three other common patient body positions tested. Because the left lateral decubitus position has other advantages (eg, prevention of aspiration) in addition to minimizing drug absorption, we recommend that orally poisoned patients be placed in the left lateral decubitus position for prehospital and initial ED management.
