Septic Shock in a Dialysis Patient With Reduced Ejection Fraction

Highest priority: antibiotics and hemodynamic resuscitation within the hour. Recognition first - this is septic shock (infection plus vasopressor-requiring hypotension or lactate ≥4), so the clock starts at triage, not at diagnosis.

Simultaneous actions:

• Move to the monitored bed, upright positioning, continuous cardiac and SpO2 monitoring.
• Two large-bore IVs; draw blood cultures x2 plus CBC, CMP, coags, repeat lactate, blood gas, and type and screen before antibiotics - but do not let culture collection delay antibiotics beyond a few minutes.
• Antibiotics within 1 hour: for health-care-associated pneumonia give broad beta-lactam coverage, e.g., piperacillin-tazobactam (renally dosed 2.25 g) or ceftriaxone 2 g plus coverage for resistant organisms per local antibiogram; check allergy history.
• Fluid: 500 mL balanced crystalloid bolus with reassessment, not a reflexive 30 mL/kg.
• Norepinephrine if MAP stays below 65 mmHg after the first bolus - start early, do not wait for a central line.
• 12-lead ECG, portable chest film, bedside ultrasound for lung B-lines and cardiac function.
• Clarify code status and goals of care now, before deterioration.

Pitfall specific to this patient: he is anuric, so urine output cannot be used to judge resuscitation - rely on MAP, mentation trend, capillary refill, lactate clearance and lung findings.

The 30 mL/kg figure is a starting estimate, not a mandate. For this man 30 mL/kg is roughly 2.5 L. In a patient with EF 30% and no renal clearance, that volume can cause pulmonary edema and worsen oxygenation in a patient already at 91% on room air. Current sepsis guidance explicitly endorses individualized fluid resuscitation with frequent reassessment.

Practical approach:

• Give 250–500 mL balanced crystalloid over 5–10 minutes; reassess MAP, mentation, capillary refill, lung sounds and bedside B-lines after each aliquot.
• He may be genuinely hypovolemic from yesterday's dialysis with poor oral intake, so a modest total (perhaps 1–1.5 L) may be appropriate - but only as tolerated.
• Stop fluids and start vasopressors when MAP remains below 65 mmHg despite initial volume, or when pulmonary congestion develops.

Vasopressor choice: norepinephrine is first line, started peripherally through a well-checked large-bore IV if needed (extravasation risk is low over hours and delay is more dangerous). Titrate to MAP 65 mmHg; add vasopressin 0.03 units/min if norepinephrine exceeds roughly 0.25–0.5 mcg/kg/min. Avoid phenylephrine as a primary agent.

Dialysis coordination: call nephrology early. Ultrafiltration treats volume overload and acidosis but is usually deferred until he is hemodynamically stable; vasopressors can run during dialysis. Remember antibiotic dosing is renal - verify each drug with pharmacy.

First, separate the two issues: what decision is being made, and who has authority to make it.

1. Assess capacity directly. With GCS 13, mumbling, and an acute septic encephalopathy, he very likely lacks capacity to weigh a complex trade-off. Document the elements you tested: ability to state a choice, understand the relevant information, appreciate the consequences, and reason about it.
2. Do not promise either way at the bedside. Express empathy, explain that the immediate goal is to treat a potentially reversible infection with antibiotics, oxygen and fluids, and that intubation is not currently indicated.
3. Find the document. Ask the daughter to call the facility and his primary care physician; obtain and read any written directive. A DNI/POLST applies specifically to intubation and should be honored when it is valid and clinically applicable.
4. Convene the right people - attending emergency physician, social work, palliative care or ethics for a time-limited goals-of-care conversation about what treatments are consistent with his stated wishes.

If he deteriorates before the document is available: act under the emergency exception and implied consent to stabilize, since withholding oxygen or ventilatory support from a patient with a reversible cause while a directive is being located risks harm. Use the least invasive effective support (HFNC or NIV if he can protect his airway and is coherent enough to tolerate it), keep reassessing, and be ready to intubate if he is failing. Document the sequence, who was contacted, and the time. If a valid DNI is in hand, honor it and shift to comfort-focused care rather than intubating "just in case."
