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.

To clarify the recent perception of shortfalls in anesthesia physician resources, two models were used to assess these resources in Ontario, Canada. ⋯ This conservative approach indicates that the shortfall in anesthesiologist physician resources will worsen by 2005.

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.
