🤔What's IncrEMentuM?

A new conference and a pivotal gathering for emergency medicine professionals worldwide, has become an essential platform for education, collaboration, and advocacy, especially in light of emergency medicine’s recent recognition as a specialty in Spain. The conference is praised for its outstanding production quality, engaging speakers, and its capacity to foster a global community of emergency care professionals.

🦪Pearls from George's IncrEMentuM 2025 Lectures:

Sodium Bicarbonate Use:
- Appropriate Use: Focus on specific instances like metabolic acidosis with renal failure or severe metabolic cases with tox patients (e.g., salicylate or TCA overdose).
- Emphasis on Patient-Centric Care: Treat the patient, not the number; avoid harmful overreliance on bicarb based solely on lab results
Diabetic Ketoacidosis (DKA):
- Balanced Solutions: Preferenced over normal saline to prevent hyperchloremic acidosis.
- Potassium Management: Oral potassium is effective and should be utilized, challenging the myth of impaired gastric absorption in DKA.
- Squid Protocol: Usage of ultra-rapid insulin subcutaneously as an alternative to insulin drips in mild to moderate DKA cases.
- We covered this topic before on REBEL EM. Check out the post here and the podcast here
Crashing Aortic Dissection:
- Hypotension Insights: Do not attribute sudden hypotension solely to medication; prioritize ruling out tamponade or cardiogenic shock.
- Ultrasound Utilization: Essential tool for detecting complications like tamponade or low EF due to myocardial infarction or aortic valve regurgitation.
- Controlled Pericardial Drainage: Crucial technique to stabilize hemodynamics without increasing mortality, avoiding extensive fluid removal.

Hyperkalemia
- Not every patient needs calcium. Dont just give it prophylatically, only those with EKG changes should get it and get enough of it.
- Give an appropriate dose of your other medications. That includes giving 10 units of insulin and 2 amps of dextrose 50. One when they get the 10 units of insulin and the other 30 minutes later
- Patients may be dehydrated, dont give them furosemide or diuretics. Those patients need fluid to help perfuse their kidneys and eliminate potassium
- Here’s the Algorithm George mentioned in the episode
- Here’s a REBEL REVIEW breaking down the different electrolytes in each of the types of fluids:

🫣Teasers from George's IncrEMentuM 2026 Lectures:

Severe Thyroid Storm:
- Diagnosis Reminder: Consider thyroid storm in febrile patients with altered mental status; order TSH tests.
- Beta Blocker Administration: Use ultrasound to assess heart function before administering propranolol to prevent low output heart failure.
- Medication Timing: Administer iodine after antithyroid drugs.
Refractory Hypoglycemia:
- Early Use of Octreotide: Beneficial in sulfonylurea-induced cases; initiate treatment promptly for better efficacy.
- Broadened Perspective: Consider other endocrine disorders as potential causes beyond typical measures.
Modern Management of SCAPE:
- Bolus Dose Nitroglycerin: A recommended practice for quick patient stabilization and improved outcomes in SCAPE scenarios.
- We covered this topic before on REBEL EM, see Dr. Marco Propersi’s post here
