Resident Lecture – Brenda – Harlem Trauma Diaries
- Always ABCDE
- Case 1: 40M Stab in neck and laceration to right UE with tourniquet
- Screaming “I can’t breath”
- Classically: Zone 2 = OR
- CTA everybody if stable, if platysma violated
- Hard signs = Go to OR
- Became hypotensive/tachycardia → started MTP
- Case 2: 23M “jumped over bunch of garbage cans”
- Edema on right thigh
- Took Kratom (can → QTc prolongation, serotonin syndrome)
- http://www.emdocs.net/toxcard-kratom-2/
- Kratom = kind of like PCP + Loperamide
- Case 3: 80M huge hematoma side of face
- IOP = 60
- Complete visual loss within 60-100 mins
- Indications for lateral canthotomy:
- IOP >40
- Proptosis
- Contraindications:
- Globe rupture
Faseeh – CCU EKG lecture #1
- STEMI vs OMI
- Dr. Smith’s ECG Blog: The OMI Manifesto
- STEMI criteria (70% sensitivity for occlusion, doesn’t include STEMI equivalents which can benefit from reperfusion)
- ER physicians more sensitive at calling STEMI
- ECG changes in ACO
- Wellens syndrome: DO NOT stress test (they have critical LAD stenosis which → MI), go straight to cath lab
- Spodick’s sign: downsloping TP segment, esp in II, seen in ~30% pericarditis
- “Witting found that Spodick’s sign occurred in 29% of patients with pericarditis and 5% of patients with STEMI” (LIFTL post)
- Benign Early Repolarization:
- Fish-hook pattern esp in V4, very typical, BER findings more prominent when bradycardic
- ,
- T wave will be more prominent than STE
- Concave ST segment
- Asymmetrical T wave
- No Terminal QRS Distortion
- Absence of both an S wave and J wave in either of leads V2 or V3
- Left Ventricular Hypertrophy: voltage criteria and one non-voltage
- Sokolow-Lyon: S wave in V1 and tallest R wave in V5 and V6 >35 mm
- Common Criterias used: Left ventricular hypertrophy
- Sensitivity of criteria (numerous studies): Accuracy of ECG criteria for the diagnosis of left ventricular hypertrophy: a comparison with magnetic resonance imaging
- Non-voltage: 2 criterias
- Increased R wave peak time > 50 ms in leads V5 or V6
- ST segment depression and T wave inversion in the left-sided leads: AKA the left ventricular ‘strain’ pattern
- Sokolow-Lyon: S wave in V1 and tallest R wave in V5 and V6 >35 mm
- STE > 20% of QRS complex then OMI in LVH – STEMI criteria not sufficient in severe LVH
Dr Rizzo – Radiology Rounds – Upper Extremity XRs
- Scapula fracture = rare = 1% of fractures
- Associated with high velocity trauma
- Palpate scapula on elderly FOOSH injuries
- Scapula fracture.. Now look for neurovascular injuries and other injuries

- 3rd most common bone that elderly fracture
- OR indications – for proximal humerus fractures
- Comminuted fractures
- Greater tuberosity fractures (w/ displacement or angulation)

- Ulnar nerve injury concern – assess with grip strength and sensation of 4th and 5th digits
- Posterior elbow dislocation
- Most common dislocation of elbow
- Reduce by traction/countertraction
- Tip: pt prone with arm hanging, and downward traction from wrist
- You can use saline bags/weights tied to wrist
- Essex-Lopresti: characterized by a fracture of the radial head, dislocation of the distal radioulnar joint and rupture of the antebrachial interosseous membrane
- Interosseous membrane disruption causing forearm instability, pt won’t be able to pronate and very weak grip strength
- Nightstick fracture: isolated ulnar shaft fracture, defense injury, high chance of compartment fracture
- ALWAYS get more than 1 view if possible – in any xray
Dr Cocchiara – ED Trauma: Part One
