Randomized Controlled Trial Comparative Study Clinical Trial
Ondansetron versus droperidol or placebo when given prophylactically for the prevention of postoperative nausea and vomiting in patients undergoing middle ear procedures.
To compare the prophylactic administration of ondansetron with droperidol or placebo to determine its effectiveness in reducing postoperative nausea and vomiting after middle ear procedures. ⋯ Ondansetron 4 mg i.v. is as effective as droperidol and better than placebo in preventing nausea and vomiting in patients undergoing middle ear surgery. No cost advantage as determined by lower use of rescue antiemetics or shorter PACU times was noted after the prophylactic administration of ondansetron.

Randomized Controlled Trial Clinical Trial
Reduction of propofol injection pain with a double lumen i.v. set.
To investigate if the use of a new double lumen i.v. set (DLIS) decreases the incidence of propofol injection pain compared with single lumen i.v. set (SLIS) administration. ⋯ The DLIS significantly reduced the incidence of propofol injection pain compared with SLIS. Further studies are indicated to evaluate the cost-effectiveness of this device.

Randomized Controlled Trial Clinical Trial
Intrathecal neostigmine for postoperative analgesia after orthopedic surgery.
To establish a dose-response curve for the analgesic effect of intrathecal neostigmine in patients undergoing below knee surgery with spinal anesthesia. To assess adverse effects, principally nausea and vomiting. ⋯ Intrathecal neostigmine produced a dose-independent analgesia and a dose-dependent incidence of adverse effects with the doses studied.

For more than 40 years, succinylcholine has been the traditional choice of muscle relaxant to facilitate tracheal intubation, particularly for anesthesia in the emergency patient with a full stomach. This presentation reviews factors that determine the onset of neuromuscular blockade, particularly with regard to tracheal intubation. Measurement of neuromuscular block, both clinical and via nerve stimulators, is described and compared, and correlations with intubating conditions are attempted. ⋯ None of the currently available drugs, or those undergoing clinical investigation, possesses the rapid onset and prompt recovery of succinylcholine. Despite the formidable side effect profile of succinylcholine, it has not been replaced by a nondepolarizing agent for use in emergency conditions. However, the alternatives, particularly rocuronium and mivacurium, are drugs with a greater safety profile that, in many circumstances, can substitute for succinylcholine.

To determine if the ordering of unindicated preoperative laboratory tests is different for healthy (ASA physical status I and II) versus sicker (ASA physical status III) patients, and to examine the financial implications at our institution of unindicated preoperative testing. ⋯ A large percentage of preoperative tests ordered by surgeons at our institution are not indicated. Eliminating unindicated tests would cut hospital revenues in a climate where testing is fee-for-service and would save the hospital money in a managed-care or capitated system.
