ALCAPA
  • The key to diagnosis of ALCAPA is the ECG.
  • ECG findings that should make you think of ALCAPA....1) Deep Q waves in lead I and aVL. 2) T wave inversion in I, aVL, V5,V6
  • ALCAPA is most common a cause of cardiac ischemia in children.
  • It has a 90% mortality rate in the 1st year if not surgically repaired. 


Pediatric Sinusitis
  • Must have >10 days of persistent cough, congestion or both, WITHOUT ANY IMPROVEMENT to diagnose acute bacterial sinusitis.
  • Have a high index of suspicion for CNS complications of sinusitis. Most common presenting complaints of fever and headache. 
  • Staph intermedius causes abscesses! If this bug is isolated...FIND the abscess.

Leukemia Emergencies - Dr. Smith

7/17/2014

0 Comments

 
Picture
1. Leukostasis is a medical emergency and requires emergent intervention. 
      - High mortality rate (up to 40%)!
      - Can cause end organ damage - may present with neuro symptoms (like ischemia).
      - Start IV Fluids to dilute the WBC.
      - Hydroxyurea can also help decrease WBC.

2. Always consider tumor lysis syndrome in any child who recently started chemotherapy.
     - Seen with conditions with large tumor burden (ex, large solid tumor, leukemia).
     - Look for High Potassium, High Phosphorous, and LOW Calcium!
     - Start IV Fluids
     - Check ECG. Treat Hyperkalemia!
     - Rasburicase for elevated uric acid.

3. It's okay to wait for the results of a CBC with diff in stable appearing patient on chemotherapy with a fever.
     - Neutropenic Fever untreated has a high mortality (80%), but treated appropriately it is 1-3%.

4. Involve oncology early whenever one of their patients arrive in the CED.

The ACEP TPA/Stroke Policy: Putting Fires Out W/ Gasoline - Dr. Asimos

7/17/2014

0 Comments

 
Picture
1. Perceived conflicts of interest resulting in blind spot bias exist among stroke opinion leaders and the authors of the ACEP tPA Clinical Policy.

2. For Clinical Guidelines to be trustworthy, they must: 1) have transparent methodology, 2) manage conflicts of interest, 3) have a balanced guideline development group composition, and 4) have undergone adequate balanced external review.

3. It is unlikely that the revised ACEP tPA Clinical Policy will substantially impact current perspectives related to the use of IV tPA for stroke

Cost-Effective Care in the ED - Dr. Sawyer

7/17/2014

Picture
Background on Costs of Care in the US

· Health Care expenditure consumes 17.7% of US GDP, almost twice the average of other industrialized nations at 9.3%.
· Heath outcomes indicators are no better in the US than in other industrialized nations.
· Unnecessary medical tests and procedures are estimated to cost $700 billion/year in the US, 5% of GDP.
· Approximately 2/3 of US bankruptcies are due to medical bills.


Defining Value in Health Care

·  Value = (Outcomes/Cost)
·  Outcomes are dependent on results, not the volume of medical tests and procedures we order/perform.
·  Costs are dependent on the volume of medical tests and procedures we order/perform.
· To increase value, we must improve outcomes, while being mindful of the volume of medical tests and procedures we order/perform.


Cost-Effective Care Strategies in the ED

· Utilize validated clinical decision rules (CDR) such as the Canadian Head CT Rule, and basic published guidelines such as the ACEP “Choosing Wisely” List of Top 5 Things Physicians & Patients Should Question.
· CDR and publish guidelines are only effective in reducing costs if available to Physicians at time of order entry.  Thus, electronic medical records should integrate decision support tools as part of the flow of order entry.
· Cost transparency & Physician Cost Sensitization have been shown to help reduce costs of care when the Physician knows the cost of the interventions they are ordering.
· Utilize Lean Methodology to improve workflow, eliminate waste, and improve outcomes.


Considerations

·  Diagnostic laboratory testing/ imaging, as well as admissions are important uses of resources; remember this during your daily practice.
· Physician practices are established in Residency and are difficult to modify after completion.
· Learning to be a good steward of health care dollars is an important part of medical education and will continue to have an ever increasing impact on our practice; take costs of care into consideration with every patient encounter.

Picture
Transplanted organs 
- don't act like normal organs 
- won't hurt and are in weird locales


RAID - Potential Complications to Consider

Rejection
   - Hyperacute - w/in minutes - we won't see
   - Acute
   - Chronic   

Anatomy

   - Vascular - stenosis, aneurysm, thrombosis
   - Nonvascular - leak, scar formation, dislodged stint, stone formation

Infection
   - First 28 days - nosocomial
   - 1-6 months - viral infections - CMV, hepatitis, EBV, HH6; oppurtunisitcs - PCP, listeria, fungal
   - > 6 months - Healthy - UTI, PNA, cold, Chronic viral infection - EBV, zoster, HSV

Drug Toxicity
   - Transplant immunosuppressants - cyclosprine, tacrolimus > can hurt the kidneys; 
   - Imuran, cellcept - hematologic effects
   - Lots of Drug- Drug interactions

Necrotizing Fasciitis - Dr. Beverly

7/10/2014

0 Comments

 
Picture
Core Concepts
• Prompt surgical consultation is recommended for patients with aggressive infections associated with signs of systemic toxicity and suspicion for necrotizing fasciitis.
• Empiric antibiotic treatment should be broad and initiated early.
• The LRINEC is a useful diagnostic adjunct in management to stratify patients who in the low, medium and high risk categories to aid in clinical management.
• Goal as an ED physician is to identify these patients, aggressively resuscitate them and get surgery involved quickly.

Risk Factors 
- old, DM, ETOH, immunocompromised, systemic disease (renal, heart, PVD)

Classification 
- Anatomic
- Depth
- Microbial cause (polymicrobial [type I = most common], monomicrobial [type 2 = strep & staph], vibrio [type 3])

Clinical Features 
- nec fas is a clinical diagnosis
> Pain at site of infection
> Blisters/ bullae
> Vital sign abnormalities

LRINEC 
- CRP, WBC, Hgb, Na, Cr, Glucose
     > Low (<5) - prob < 50%, intermediate (6-7) prob 50-75%, High (>8) prob >75%

Diagnosis 
- basic labs, imaging - US, plain films, CT - 80% sensitive, MRI

Treatment 
- OR!!!!!
- Antibiotics - PCN & Clindamycin (group A strep) - but cover broadly - vanc + zosyn

Teaching points from our surgical colleagues 

    1. Early diagnosis
    2. Early & extensive surgical intervention
    3. Life over limb

Case 1 - S/P Arrest w/ STEMI
  • STEMI  - >1 mm STE at the J point in 2 contiguous leads or greater than 2 mm STE in 2 contiguous leads isolated to leads V2-V3; reciprocal depression makes diagnosis more likely but not necessary for diagnosis. 
  • RBBB - causes = ischemia, functional, iatrogenic 
      > Definition - QRS >120 ms; RSR' pattern v1-v3, slurring of S wave in lateral leads
  • Diagnosis of STEMI in the setting of RBBB does not require special diagnostic criteria.
  • Consider RBBB as the result of an anterior MI (LAD lesion) rather than as a “benign bystander.”
  • AHA recommends PCI for patients with aFMC-to-device time system goal of 120 minutes or less and fibrinolytics for patients > 120 minutes (FMC = first medical contact).
  • Using a cutoff of 20 minutes from arrest to ROSC captures 96% of survivors and achieves a survival rate of 82%.


Case 2 - Ear Pain and Facial Palsy
  • Gradenigo’s Syndrome: Triad of otorrhea, retro-orbital pain, and CN VI palsy (diplopia).
  • Consider Gradenigo’s in patients with a cranial nerve palsy in the setting of acute or chronic otitis media.

Case 3 - Ataxia and Headache after Rollercoster Ride
  • Wallenberg Syndrome- lateral medullary syndrome- is an acute infarct involving the lateral medulla oblongata
  • It is the most common brainstem stroke
  • Patients present with vertigo, facial numbness, dysarthria, dysphagia, ataxia, and cerebellar signs
  • Consider CNS pathology in patients presenting with neurologic complaints after a roller-coaster ride

Hypoglycemia - Don't Get Fooled!!

7/3/2014

0 Comments

 
PictureDr. Fox
HYPOGLYCEMIA
Presentation:
  • Classic Hypoglycemia Symptoms = Both autonomic and neuroglycopenic symptoms
  • Autonomic = catecholamine release -> tremor, tachycardia, and diaphoresis.
  • Neuroglycopenic -> confusion, Seizures, and coma
  • Many pts do not present in the “classic” fashion.
  • Interestingly - Can actually present with FOCAL Neurologic deficit… SO CHECK GLUCOSE BEFORE CALLING CODE STROKE!!

Not all patients recognize their own hypoglycemia well.
  • Often we get used to diabetics stating that they think their sugar is low.
  • Unfortunately, they may not perceive their own level well.
  • Additionally, they may have symptoms at “normal-low” levels.
  • Poorly controlled diabetics first developed symptoms at a mean glucose of 78 mg/dL in one study.
  • Patients on beta-blockers may not have significant autonomic symptoms.

Some patients that are at high risk for hypoglycemia:
  • Children (See Morsel) - high metabolic demands
  • Alcoholics - ETOH inhibits gluconeogenesis and depletes glycogen stores. Plus they don’t eat much.
  • Elderly - cuz they often don’t eat many calories.

Treatment - we often do it wrong!

  • “Give ‘em an amp”
  • Treatment should be 0.5 - 1 g/kg IV of 50% Dextrose (D50W).
  • Use 2 g/kg of D25 in kids and 5 g/kg of D10 in infants.
  • Standard “amp” of D50 has 25 grams.
  • Most adults should get more than one amp.
  • Each “amp” is only 100 cal.
  • Each treatment should be followed by a meal (if patient able to eat).
  • Glucose drip - Need to use D10 (D5 x 1 litre contains only 50 grams (200 cal)).
  • D20 is even better… but requires central line.
  • Glucagon?? -- Useful if you can’t get an IV. Requires adequate glycogen stores to be present to work… may not be effective in kids and alcoholics.
Main Point - Change in Mental Status? Check Glucose early!!

Be A Good Trauma Captain - Dr. COLUCCIELLO

7/3/2014

0 Comments

 
Picture
THE TRAUMA CAPTAIN CAN HAVE A BIG IMPACT!
-Good trauma rescucitation can have large impact on outcomes
-Good rescuc should be organized, quiet, and rapid

-Simulation important, ATLS compliance increased 56% to 83%, procedure completion time reduced
-Review and understand the established protocols for trauma


Before a CODE
-Check code criteria and establish if appropriate personnel present
-Assign roles: airway, procedures, ultrasound. 
-Anticipate possible procedures and prepare drugs/equipment
-Set expectations prior to arrival of pt - expected time to completion of code/rescucitation
-Be Loud and Calm


At the CODE
-Establish your leadership - "Everybody listen up"
-Move patient after medic report
-ABCs, primary and secondary survey, monitoring, lab studies
-Continually articulate the plan and ultimate disposition.  "Why are we still here?"
-Feel them feet


Assessing shock
-Where's the blood? External, chest, abdomen, thighs, retroperitoneum
-Pain control: Caution if shock, AMS, elderly


Geriatric
-No drama, quiet, can betray how sick they are
-Low reserve, normal VS until crash
-Get a lactate, liberal CT scanning
-Admit these patients


Pre-CT check list
-CT is a dark place where trauma patients go to die
-Before CT, do you Need ET tube? Chest tube? Pelvic binder? Tourniquet? Splints?
-Do they really need CT, or do they need OR, angiography, or transfer?

Picture

Mechanisms of hyperthermia
  • Hurt the hypothalamus or mess with NT
  • Increased muscle activity
  • Vasoconstriction
  • Uncoupling cellular respiration

Malignant Hyperthermia

   - Rare
   - Increased peripheral muscle activity due to ryanodine receptor issues - genetic component
   - Only seen with anesthesia - halothane, succinylcholine
   - Fast onset from exposure, severe and short lived - hyperK, muscle rigidity, autonomic instability,
   - increased CO2 on capnography


Neuroleptic Malignant Syndrome

   - Due to altered DA transmission - seen with typical antipysch meds, lithium, environmental (heat)
   - Subacute, severe, lasts day-weeks
   - Lead pipe rigidity, autonomic instability, AMS


Parkinsons Disease
   - abrupt withdraw of DA agonist therapy can cause hyperpyrexia



Cocaine/ Stimulants
  - Hypothalamic stimulation, vasoconstriction, increased muscle activity
  - Fast onset, short duration, severe hyperthermia


Serotonin Syndrome

   - Increased central 5HT activity
   - More common in drug drug interactions - SSRI/SSRI or SSRI & other serotonin agonists - TCA,
     demerol, linezolid, MAOI, tramadol, dextromethrophan (MAOI activity)
   - Subacute, moderate severity
   - AMS, muscle rigidity (LE>>UE), hyperreflexia & rigidity, autonomic instability

   - NBOME - designer drugs - increased serotonin activity


OTHERS:
Anticholinergic

   - increased muscarnic blockade
Salicylate toxicity

   - uncouples cellular respiration
Baclofen withdraw


Complications from hyperthermia

  - Resp, PE, rhabdo, hepatic failure, hyperK


Treatments

- DC offending agents or restart withdrawn med
- Physical cooling
- Sedation - benzos, non depolarizing blockade


 - Secondary Treatments
      > Cyproheptadine - serotonin antagonist (for 5HT syndrome) - PO only
      > Dantrolene - for malignant hyperthermia - first line agent
      > Limited evidence for NMS - dantrolene has been tried - don't use as monotherapy
      > Dopamine agonist - bromocriptine, amantadine - dont use as monotherapy (long time to start acting)

     > ECT - unknown mechanism

54000 or 800-222-1222 - poison control
