Randomized Controlled Trial Comparative Study Clinical Trial
Cervical plexus anesthesia for carotid endarterectomy: comparison of ropivacaine and mepivacaine.
To evaluate the effectiveness of cervical plexus block performed with ropivacaine 0.75% or 1%, or mepivacaine 2%. ⋯ Ropivacaine 0.75% or 1% are appropriate choices when performing cervical plexus anesthesia for carotid endarterectomy, providing nerve block characteristics similar to those of mepivacaine 2%, but with the advantage of longer postoperative pain relief.

Randomized Controlled Trial Comparative Study Clinical Trial
A comparison of patient-controlled analgesia fentanyl and alfentanil for labour analgesia.
To determine the analgesic efficacy of equipotent doses of PCA (patient-controlled analgesia) fentanyl and PCA alfentanil for labour pain. ⋯ In the doses prescribed in this study, PCA fentanyl was found to provide more effective analgesia in late first stage labour than PCA alfentanil.

Randomized Controlled Trial Comparative Study Clinical Trial
Comparison of differential blockade during spinal anesthesia using isobaric vs. hyperbaric lidocaine 2%.
To compare the extent of the sensory, motor and sympathetic block produced by a single dose of 60 mg lidocaine at the same concentration (2%) and volume but at different baricity injected intraspinally. ⋯ The baricity of 60 mg lidocaine injected intraspinally in the lateral decubitus position did not influence the cephalad spread of sensory or sympathethic blockade. In the hyperbaric group, the dependent side showed a more pronounced sensory (pinprick, ice), and motor block.

To describe negative pressure pulmonary edema due to biting of the laryngeal mask tube at emergence from general anesthesia. ⋯ Airway obstruction due to biting of a laryngeal mask tube may result in negative pressure pulmonary edema.

Comparative Study
Neuromuscular effects of rapacuronium in pediatric patients during nitrous oxide-halothane anesthesia: comparison with mivacurium.
To describe neuromuscular effects of rapacuronium in pediatric patients during N2O-halothane anesthesia and compare them with mivacurium in children. ⋯ Rapacuronium produces block earlier than mivacurium. Recovery from rapacuronium block is dose related and slower than that following mivacurium during halothane anesthesia.
