A podcast dedicated to the teaching of critical care. The focus audience is physicians, residents, medical students, nurses, therapists, and paramedics. These are topics that arise while on teaching rounds in the Burn ICU at Vanderbilt Medical Center. A broad scope of critical care and prehospital topics are presented as well as recent journal articles and medical news.
Hyponatremia represents a critical clinical challenge in surgical and intensive care units, often manifesting as encephalopathy due to cerebral edema and fluid shifts. Diagnosis relies on assessing serum osmolality, urine sodium levels, and patient volume status to distinguish between etiologies such as SIADH, adrenal ...
Primary percutaneous coronary intervention (PCI) serves as the preferred revascularization strategy for acute myocardial infarction, offering superior restoration of coronary blood flow and lower intracranial hemorrhage risks compared to thrombolytic therapy. High-risk patients, including those over 75 or experiencing ...
Crush syndrome and traumatic rhabdomyolysis result from prolonged muscle compression, leading to severe ischemia and systemic toxicity upon reperfusion. The release of intracellular components like potassium and myoglobin poses life-threatening risks, most notably acute kidney injury caused by myoglobin-induced tubular...
Myocardial infarction occurs when an atherosclerotic plaque ruptures, forming a thrombus that occludes coronary blood flow and causes severe oxygen deprivation. The heart, an aerobic organ with limited anaerobic capacity, responds to ischemia through contractile dysfunction, which may manifest as stunned or hibernating...
Hypercalcemia, defined as ionized calcium greater than 10.5 mg/dL, is the central topic, particularly its manifestation, diagnosis, and treatment within the surgical ICU. Common symptoms include altered mental status, hyporeflexia, and muscle weakness, while chronic cases may show bone changes. The causes range from ma...
Abdominal compartment syndrome represents a critical condition defined by intra-abdominal hypertension exceeding 20 mmHg alongside new-onset organ dysfunction. Rather than relying on a binary "good number versus bad number" approach, clinicians must evaluate the interplay between abdominal organ volume, space-occupying...
