Randomized Controlled Trial Comparative Study Clinical Trial
A random trial comparing recovery after midazolam-alfentanil anesthesia with and without reversal with flumazenil, and standardized neurolept anesthesia for major gynecologic surgery.
To compare the recovery characteristics of total intravenous anesthesia (TIVA) using midazolam-alfentanil, with or without reversal with flumazenil to a standardized neurolept anesthesia with nitrous oxide (N2O). ⋯ TIVA with midazolam and alfentanil can be used for major gynecologic surgery. Recovery in the neurolept group was equal to recovery in the TIVA group without reversal, and flumazenil improves the recovery after midazolam anesthesia. Overall, in comparison with the neurolept technique no major advantage could be demonstrated using TIVA with midazolam-alfentanil.

Randomized Controlled Trial Comparative Study Clinical Trial
Postoperative analgesia and plasma levels after transdermal fentanyl for orthopedic surgery: double-blind comparison with placebo.
To determine whether transdermal fentanyl can provide a significant component of postoperative analgesia. ⋯ Efficacy of transdermal fentanyl for postoperative pain relief is shown, but intense respiratory depression is sometimes seen.

Randomized Controlled Trial Clinical Trial
Nebulized bupivacaine attenuates the heart rate response following tracheal intubation.
To determine whether nebulized bupivacaine attenuates the acute hemodynamic response to laryngoscopy and intubation. ⋯ Nebulized 0.75% bupivacaine was only partially effective in blunting the hemodynamic response to tracheal intubation.

Randomized Controlled Trial Comparative Study Clinical Trial
Pretreatment with sedative-hypnotics, but not with nondepolarizing muscle relaxants, attenuates alfentanil-induced muscle rigidity.
To evaluate and compare the efficacy of various pretreatment agents to attenuate or prevent opioid-induced muscle rigidity using a well-established, previously described clinical protocol. ⋯ This study suggests that benzodiazepine pretreatment is frequently, but not always, effective in preventing opioid-induced muscle rigidity.

Randomized Controlled Trial Comparative Study Clinical Trial
Serum and urine inorganic fluoride levels following prolonged low-dose sevoflurane anesthesia combined with epidural block.
To determine whether serum and urine inorganic fluoride levels with prolonged (more than 7 hours) low-dose (0.8 to 2.0 vol %) sevoflurane anesthesia plus epidural anesthesia were increased as compared with isoflurane anesthesia plus epidural anesthesia. To measure the urine tubular enzymes N-acetyl-beta-glucosaminidase (NAG), alpha 1-microglobulin (alpha 1-M), and beta 2-microglobulin (beta 2-M) for renal tubular injury in both groups. ⋯ There was no increase in urinary enzymes, which are indicators of tubular injury, specific to sevoflurane. There was no postoperative renal dysfunction, as indicated by unchanged serum creatinine and blood urea nitrogen levels.
