Management of Traumatic Subarachnoid Hemorrhage

Prioritization of following steps is based on individual patient needs: 1. Assess stability – stabilize – neuroprotective intubation as needed 2. Determine secondary damage – neuro exam, including GCS – CT scan 3. Treat (may begin simultaneously with 1 and 2) – reverse anticoagulation as necessary – prevent potential seizures – minimize cerebral edema –Read more

Medical Statistics – a Primer on Concepts

Medical statistics review (assuming some basic familiarity): Mean (average), median (middle number), mode (most common number) Sensitivity and specificity depend on a specific, pre-determined test. Also, they do NOT depend on prevalence of the condition being tested for. Positive predictive value and negative predictive value depend on the prevalence of the condition being tested for.Read more

The Normotensive Pulmonary Embolism Patient

Early death (within 7-30 days) in PE patients is concerning. It is relatively easy to identify high-risk PE patients, defined by abnormal vitals SBP < 90 or drop in SBP by 40 for at least 5 min. Normotensive patients with poor prognostic indicators include (statistically significant odds ratios): – SBP between 90-100 (OR 2.45) –Read more

Criteria for St Segment Elevation

Different criteria exist based on gender, age, and ethnicity: – new 1 mm of STE in 2 contiguous leads except for V2-V3 – 2 mm of STE in V2-V3 in men > or = 40 – 2.5 mm of STE in V2-V3 in men < 40 – 1.5 mm STE in V2-V3 in women – strongly considerRead more

A Pediatric Pearl

This week, PECARN published a study that determined that isolated loss of consciousness (LOC) is not a strong enough predictive factor for a clinically significant traumatic brain injury, which they define as requiring intubation, extended inpatient observation, and/or neurosurgical intervention (rate of  0.5% (95% CI, 0.2-0.8; 13 of 2780). The rate is slightly higher forRead more
