Randomized Controlled Trial Comparative Study Clinical Trial
Ketamine and oxycodone in the management of postoperative pain.
Relief of pain, whether post-traumatic or postoperative, is a prerequisite for the prevention of its deleterious effects on the whole organism. Unalleviated pain also increases the victim's or patient's anxiety and apprehension, which in turn increase the intensity of the pain. In the management of pain, opiates have maintained their position as the most common form of analgesic therapy despite the many side effects associated with their use. ⋯ Also, the suitability of oxycodone for field use was evaluated with respect to ketamine. Plethysmographic pulse-wave amplitude changes were compared with the pain visual analogue scale scores as measures of postoperative pain. The results of this study did not reveal any significant differences between the analgesic potencies of the studied drugs and clearly demonstrate that even suboptimal doses of both ketamine and oxycodone can provide appreciable relief of pain.

Randomized Controlled Trial Comparative Study Clinical Trial
Simplified use of mixed propofol and alfentanil for anesthesia in remote locations.
Total intravenous anesthesia (TIVA) is a useful technique in precarious situations in which anesthesia ventilators and medical gas can be difficult to obtain. The aim of the study is to compare TIVA technique using a simplified infusion scheme for propofol and alfentanil mixed together (45 ml of propofol 1% and 2,500 micrograms of alfentanil in a 50-ml syringe) with an inhalational anesthetic technique (isoflurane/N2O, sufentanil). Thirty-two American Society of Anesthesiologists physical status I patients undergoing orthopedic surgery were studied. ⋯ Only patients receiving TIVA had responses to surgery. In the TIVA group, time to extubation was shorter (16 +/- 5 vs. 25 +/- 7 minutes) and postoperative requirement for morphine was lower (6.2% vs. 25%) than in the inhalation group (p < 0.05). TIVA using a mixture of propofol and alfentanil is a reliable technique of anesthesia in patients without multiple injuries.

Randomized Controlled Trial Comparative Study Clinical Trial
A comparison of 5-minute povidone-iodine scrub and 1-minute povidone-iodine scrub followed by alcohol foam.
The purpose of this study was to determine if a 1-minute scrub with povidone-iodine followed by alcohol foam is as effective as a 5-minute scrub with povidone-iodine in reducing skin bacterial counts. A 1-minute scrub with povidone-iodine followed by alcohol foam and a 5-minute scrub with povidone-iodine was done. In the first study, cultures were obtained after 1 hour, and in the second study, cultures were obtained after 2 hours. ⋯ The study involved two groups of 12 participants and a total of 37 patients over a period of 5 months. The results show that there was no significant difference between the number of colonies cultured for the 1-minute scrub compared with the 5-minute scrub for either the 1-hour or the 2-hour study. In fact, the total number of bacterial colonies was less after the 1-minute scrub with alcohol foam than after the standard 5-minute scrub in both the 1-hour group (10 vs. 18) and the 2-hour group (18 vs. 44).

Randomized Controlled Trial Comparative Study Clinical Trial
Comparison of rectal to intranasal administration of midazolam for premedication of children.
Sixty children aged 3 to 9, undergoing minor surgical procedures, were studied to compare 0.5 mg/kg intranasal with 0.5 mg/kg rectal midazolam as a premedication. The children were evaluated for their ability to tolerate the medication, preanesthetic sedation, and alertness after anesthesia. ⋯ Rectal midazolam was much better tolerated by the children than the intranasal route (30 versus 3, p < 0.0001). We advocate the rectal over the intranasal route for premedication with midazolam in children, and anesthetic induction should occur no more than 30 minutes after administration of premedication.

Randomized Controlled Trial Comparative Study Clinical Trial
The incidence of postoperative nausea and vomiting: a retrospective comparison of alfentanil versus sufentanil.
Postoperative nausea and vomiting have been associated with the use of intravenous narcotics, and nitrous oxide may worsen the emetic effects of narcotics. Alfentanil and sufentanil are two synthetic derivatives of fentanyl; alfentanil has a shorter wake-up time than fentanyl, and sufentanil is equivalent to fentanyl. In order to study comparative emetic properties of these two drugs, patients in two different cities were randomly allocated to two different groups and retrospectively compared. ⋯ With group I, the overall incidence of nausea was 31% and of vomiting was 6.2%. For group II, the overall rate for nausea was 38.2% and 8.8% for vomiting. Statistically, there was no significant difference in nausea or vomiting between groups.
