You're at the bedside. MAP is 58. Norepinephrine is running. The nurse is asking if you want to add vasopressin. What's your next move?

Anand Swaminathan, MD () from ResusX:ReUnion:
The reflex answer to refractory hypotension is another vasopressor. But hanging a second pressor without knowing why the first one isn't working — that's a cognitive error, not a management plan.

Vasoactives don't fix the problem. They hold the line while you find it:
→ Did you miss obstructive shock? (PE? Tamponade?)
→ Is there ongoing hemorrhage?
→ Is the heart the problem, not the vessels?
→ Has your source control actually worked?

The pressor is buying you time. The question is — are you using that time to find the answer?

Your pancreatitis patient's MAP is holding, but the labs come back — platelets 18K, fibrinogen 88, PTT creeping up. Do you transfuse?

Mark Ramzy, DO () from ResusX:ReUnion:
This is where the instinct to "do something" can work against you. The WATERFALL trial reminded us that aggressive fluid resuscitation in pancreatitis → volume overload, no improvement in outcomes.

Similar logic applies to blood products in DIC:
🚫 Don't prophylactically transfuse RBCs — you risk fueling the inflammatory fire
✅ Cryoprecipitate if fibrinogen < 100
✅ Platelets if count < 20–50K
✅ FFP if PTT > 1.5x normal

The threshold matters. The indication matters. Not every abnormal lab is a transfusion order. How does your unit approach coagulopathy management in pancreatitis — aggressive correction or threshold-based? Comment below.👇

You're seeing a patient with a platelet count of 8,000. Petechiae on exam. BP is 118/74. No fever. No schistocytes on smear. Do you call the ICU?

Mark Ramzy, DO () from ResusX:ReUnion: this is where ITP management trips people up at the bedside.

🔹 ITP = autoimmune antiplatelet antibodies destroying platelets
🔹 These patients are more often hemodynamically stable than you'd expect
🔹 MAP holds. BP holds. ICU-level care is usually NOT required

The reflex to escalate care based on platelet number alone can lead you astray. ITP isn't TTP. The clinical picture here is your guide — not just the lab value. That said, management decisions still depend on bleeding phenotype, platelet threshold, and whether this is new or relapsed disease.

How does your unit approach the ITP patient with a platelet count under 10k but no active bleeding? Comment to discuss.👇

Your septic patient isn't turning around — and you're not sure why. Sound familiar? Here's the scenario: elderly patient, found down at home, clear signs of sepsis. You're doing everything right. But the MAP keeps dropping. Did they hit something when they fell?

Anand Swaminathan, MD () from ResusX:ReUnion:
Liver lacs and retroperitoneal bleeds can run parallel to sepsis — and they can be fatal if you miss them. At the bedside, the move is:

🖥️ Drop your threshold for CT, especially on the retroperitoneum
🔴 Activate MTP — don't wait
💉 TXA if the bleed is recent
🩸 1:1:1 ratio

The patient who "just has sepsis" sometimes doesn't just have sepsis. What's your threshold for CT in a septic patient who isn't responding? Let's talk.👇

You're rounding in the ICU and notice a patient's platelets have dropped from 180 to 70 — they've been on heparin for 8 days. What's your next move? 🤔

Mark Ramzy, DO () from ResusX:ReUnion says, before you do anything else, run the 4Ts score:

⏱ Time — Did the drop happen over 5–10 days? That's a red flag.
📉 Thrombocytopenia — A >50% fall scores 2 points right there
🤕 Thrombosis — Any new clots or non-erythematous skin lesions like necrosis?
❓ Alternative causes — Can you explain it with ITP, TTP, or a new med?

A high 4Ts score means you shouldn't wait for confirmatory labs before stopping heparin. The clinical window here is narrow — and the consequences of missing HIT are serious.

What does your unit's protocol look like when the 4Ts score comes back intermediate or high? Drop it in the comments.👇

Your patient is on 0.3 mcg/kg/min of norepinephrine and still dropping. You've got a working diagnosis. It made sense at first. So do you keep pushing the same treatment — or do you start asking if you missed something?

Anand Swaminathan, MD () from ResusX:ReUnion:
This is where Occam's Razor can actually hurt your patient. We all learned "one unifying diagnosis." But the full principle says: without necessity. When the MAP won't respond? That's necessity. That's your bedside signal to consider a second — or third — concurrent diagnosis.

Hickam's Dictum: Patients can have as many diseases as they damn well please. Refractory shock is one of the clearest clinical scenarios where anchoring to a single diagnosis becomes dangerous.

What's your approach when a patient isn't responding the way the diagnosis predicts they should? Comment and let's talk through it.👇

You're managing a patient in the ICU — they've been on heparin for 6 days and their platelet count just tanked. HIT is on your differential. What's your next move?

Mark Ramzy, DO () from ResusX:ReUnion:
🚫 Don't wait for the antibody panel to come back before stopping heparin
🚫 Don't transfuse platelets — this can trigger thrombosis
✅ Switch anticoagulation now — argatroban is the go-to, with fondaparinux or bivalirudin as alternatives
✅ Send the HIT panel so heparin is flagged in their chart permanently

The 4T score helps you decide how aggressively to act before confirmatory testing returns. The stakes are high — HIT is a prothrombotic state, not just a low platelet problem.

What's your institution's protocol when HIT is suspected — do you switch anticoagulants before the panel results are back? Comment below.👇
