To review the pattern of malpractice litigation related to regional anesthesia in Canada. ⋯ Twenty percent of all anesthesia claims in Canada are related to regional anesthesia. The legal outcome of these claims is favourable in 90%. Unfavourable clinical outcome is associated with catastrophic or major injury. There were no deaths in the regional anesthesia claims.

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.

Normothermic cardiopulmonary bypass (CPB) has been recently used in cardiac surgery. However, there is a controversy whether there is a difference in incidence of neurological disorder after coronary artery bypass graft (CABG) surgery between normothermic CPB and mild hypothermic CPB. In this study, we assessed the effects of normothermia and mild hypothermia (32 degrees C) during CPB on jugular oxygen saturation (SjvO2). ⋯ Cerebral oxygenation, as assessed by SjvO2 was increased during mild hypothermic CPB than during normothermic CPB.

Meperidine has local anesthetic properties and, therefore, when given epidurally it has the potential to cause hemodynamic changes. Our objective was to study the hemodynamic effects of an analgesic dose of epidural meperidine (50 mg) in 34 ASA 1-2 term parturients scheduled for elective Cesarean section under epidural anesthesia. ⋯ Epidural meperidine, 50 mg, caused minimal hemodynamic changes in term parturients.

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.
