Intraoperative spinal cord and nerve root monitoring is used to identify an insult to the neural elements with the goal of preventing injury. There are 2 major categories of monitoring: evoked potentials (somatosensory evoked potentials and motor evoked potentials) and electromyography. The availability of intraoperative neuromonitoring and the indications for use vary widely. In this study, we aimed to document the current practices and opinions of Canadian spine surgeons with regards to intraoperative spinal monitoring. ⋯ The availability of spinal monitoring in Canada is variable. Most surgeons believe that it is an important adjunct to improve patient safety.

Acute compartment syndrome of the lower extremity is a clinical condition that, although uncommon, is seen fairly regularly in modern orthopedic practice. The pathophysiology of the disorder has been extensively described and is well known to physicians who care for patients with musculoskeletal injuries. ⋯ In this article, we review the clinical risk factors of acute compartment syndrome of the lower extremity, identify the current concepts of diagnosis and discuss appropriate treatment plans. We also describe the Canadian medicolegal environment in regard to compartment syndrome of the lower extremity.

Do ß-blockers have an effect on the 30-day risk of major cardiovascular events in patients with or at risk of atherosclerotic disease undergoing noncardiac surgery? ⋯ A perioperative ß-blocker regimen results in fewer MIs but is associated with an increased risk of stroke and perioperative death in patients with or at risk for atherosclerotic disease undergoing noncardiac surgery. Patients are unlikely to accept the risks associated with perioperative extended-release metoprolol use.
