Randomized Controlled Trial Multicenter Study Comparative Study Clinical Trial
Evaluation of ketorolac, ibuprofen-paracetamol, and dextropropoxyphene-paracetamol in postoperative pain.
To compare the analgesic efficacy of ketorolac, ibuprofen-paracetamol (acetaminophen), and dextropropoxyphene-paracetamol in postoperative pain. ⋯ Ketorolac 10 mg is a superior analgesic to ibuprofen-paracetamol or dextropropoxyphene-paracetamol in the treatment of postoperative pain.

Comparative Study
Albuterol delivery by metered-dose inhaler with a pediatric mechanical ventilatory circuit model.
To determine albuterol delivery by metered-dose inhaler (MDI) in an in vitro pediatric mechanical ventilatory circuit model. The influence of a spacing device, endotracheal tube (ETT) diameter and length, and air humidity was also investigated. ⋯ In humidified air, the dose of albuterol by MDI with an AeroVent spacer should be doubled for children intubated with 6.0-mm ETT, and four puffs administered for every one puff desired for 4.0-mm ETT. The results of this investigation should prove useful in initial clinical trials of albuterol MDI in ventilator-dependent infants and children.

Randomized Controlled Trial Comparative Study Clinical Trial
Venous irritation related to intravenous administration of phenytoin versus fosphenytoin.
To compare the frequency, severity, and time course of venous irritation after administration of a single intravenous dose of phenytoin with an equimolar dose of fosphenytoin, a water-soluble phenytoin prodrug. ⋯ Fosphenytoin administration resulted in significantly less venous irritation and phlebitis compared with an equimolar dose of phenytoin. The clinical use of this water-soluble phenytoin prodrug should minimize the frequency and severity of infusion-site reactions and should allow convenient, rapid, intravenous administration of drug, undiluted or admixed with intravenous solutions.

Comparative Study
An alternative sodium bicarbonate regimen during cardiac arrest and cardiopulmonary resuscitation in a canine model.
We evaluated the effect of frequent, early bolus administration of low-dose sodium bicarbonate (NaHCO3) on blood gas values during ventricular fibrillation and cardiopulmonary resuscitation (CPR) compared with normal saline and standard bolus doses of NaHCO3. This was a randomized laboratory investigation involving 13 mongrel dogs and 18 experiments (5 dogs were used in a crossover manner). Each dog underwent 3 minutes of ventricular fibrillation, followed by 15 minutes of CPR. ⋯ In addition, SB produced arterial alkalemia (pH > 7.45) after NaHCO3 administration. The arterial pH at 18 minutes of fibrillation for SB, P, and B was 7.46 +/- 0.14, 7.29 +/- 0.07, and 7.41 +/- 0.1, respectively. Similar trends for pCO2 and pH were observed for venous samples.(ABSTRACT TRUNCATED AT 250 WORDS)

Nondepolarizing neuromuscular blocking agents (NNMBAs) are frequently administered to patients in the intensive care unit (ICU). We conducted a retrospective study of patients in intensive care who received infusions (> 48 hrs) of commonly used NNMBAs. ⋯ As a result of this study, guidelines for agent selection were developed to facilitate cost effective use of NNMBA in our ICUs. Using these guidelines would potentially significantly decrease drug expenditures in this setting.
