Kernicki-Sklar Study Guide Infectious Disease
Anna spoke about the new recommendations for antibiotic prophylaxis to prevent endocarditis. The only procedure in the ED you may want to consider giving prophylaxis for is draining an intra-oral abscess in a patient with high risk of endocarditis (prosthetic valve, prior infective endocarditis, and patients with un-repaired congenital heart disease or congenital heart disease repaired with prosthetic material)
The diagnosis of necrotizing fasciitis may not be apparent upon first seeing the patient. Overlying cutaneous inflammation may resemble cellulitis. However, features that suggest involvement of deeper tissues include (1) severe pain that seems disproportional to the clinical findings; (2) failure to respond to initial antibiotic therapy; (3) the hard, wooden feel of the subcutaneous tissue, extending beyond the area of apparent skin involvement; (4)systemic toxicity, often with altered mental status; (5) edema or tenderness extending beyond the cutaneous erythema; (6)crepitus, indicating gas in the tissues; (7) bullous lesions; and 8) skin necrosis or ecchymoses.

Lambert U/S DVT
You need to use a high frequency linear probe to scan for DVT.
The main sign of DVT is non-compressibility of the vein.
Lambert MSK Ultrasound
95+% of Rotator Cuff Injuries affect the supraspinatus muscle. The supraspinatus muscle abducts the humeurs. You can use ultrasound to identify suprasinatus tears.
