Endovascular Therapy for Acute Ischemic Stroke

March 15, 2018

Background: Approximately 80% of strokes are ischemic in origin leading to significant morbidity and mortality worldwide.  In ischemic stroke, there is usually a core infarct and an ischemic penumbra.  The penumbra is the area that we try to salvage with reperfusion therapy. Currently, systematic intravenous alteplase administered within 4.5hrs after symptom onset is the mainstay of therapy, however many question its risk/benefit ratio in ischemic stroke. 4.5 hours is a narrow therapeutic time window and many contraindications such as recent surgery, coagulation abnormalities, and history of intracranial hemorrhage inhibit many patients from receiving systemic thrombolysis.  There have been many studies evaluating endovascular therapy in the management of ischemic stroke published in the past few years.  This post will serve as a review of those studies.

Spinal Immobilization in Trauma Patients

07 Aug
August 7, 2017

Background: It has been common practice in trauma to place patients in cervical collars and on long backboards (LBBs) to achieve spinal immobilization. LBBs are used to help prevent spinal movement and facilitate extrication of patients. Cervical collars (C-Collars) are used to help prevent movement of the cervical spine and often are combined with lateral head blocks and straps. The theory behind this is that spine immobilization prevents secondary spinal cord injury during extrication, transport, and evaluation of trauma patients by minimizing movement.  Most of this information has been passed on from historical teachings, like the Advanced Trauma Life Support (ATLS) courses, and not from scientific research. To date there has been no high-quality evidence that use of spinal immobilization improves patient outcomes. In this post, we will review the evidence associated with spinal immobilization in trauma patients. Read more →
