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
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 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
Effects of subcutaneous verapamil on the duration of local anesthetic blockade.
To determine whether a subcutaneous injection of verapamil will provide local anesthesia and whether a mixture of lidocaine and verapamil will prolong the anesthetic effect of lidocaine alone. ⋯ Verapamil injected subcutaneously provides a degree of local anesthesia. However, this effect is hampered by a local reaction at the injection site and a short duration of action. The mixture of lidocaine and verapamil provides a shorter duration of action than does lidocaine alone.

Randomized Controlled Trial Clinical Trial
Evaluation of the efficacy of a forced-air warmer (Bair Hugger) during spinal surgery in children.
To evaluate the efficacy of a forced-air warmer during spinal surgery for correction of scoliosis in children. ⋯ The forced-air warmer (Bair Hugger) is effective during spinal surgery, although only about 20% of body surface area can be covered.
