Extubation on Low-Dose Epinephrine for Cardiac Issues
No, vasopressors and inotropes (including epinephrine) should be discontinued before extubation during withdrawal of life-sustaining measures, as they are non-comfort medications that do not align with the goal of comfort-focused care. 1
Context-Dependent Guidance
The answer depends critically on whether this is:
- Withdrawal of life-sustaining measures (end-of-life care)
- Standard extubation in a patient expected to survive
For Withdrawal of Life-Sustaining Measures
The Intensive Care Medicine guidelines explicitly recommend discontinuing all vasopressors and inotropes before proceeding with extubation. 1
- Vasopressors and inotropes should be discontinued first, followed by mechanical ventilation in a stepwise manner. 1
- The pace should be individualized, ensuring alleviation of pain, respiratory distress, or anxiety at each step. 1
- All non-comfort medications must be discontinued, which specifically includes vasopressors and inotropes. 1
The only role for epinephrine in this context is inhaled epinephrine to treat post-extubation stridor in conscious patients—not intravenous epinephrine for hemodynamic support. 1, 2
For Standard Extubation (Non-Palliative)
There are no specific guidelines addressing extubation while on low-dose epinephrine for cardiac support in patients expected to survive. However, clinical reasoning suggests:
- Patients requiring vasopressor support typically do not meet standard extubation criteria, which include hemodynamic stability without significant vasopressor support. 2
- The need for epinephrine indicates ongoing cardiovascular instability that would generally preclude safe extubation.
- Quantitative Train-of-Four must be >90% before any extubation attempt. 2
Critical Pitfalls to Avoid
Do not confuse inhaled epinephrine (for post-extubation stridor management) with intravenous epinephrine (for hemodynamic support). 1, 2
- Inhaled epinephrine is recommended for treating post-extubation stridor in conscious patients. 1, 2
- IV epinephrine for cardiac support is a vasopressor that should be discontinued before withdrawal of mechanical ventilation. 1
The evidence regarding epinephrine doses and outcomes is relevant primarily to cardiac arrest scenarios, not routine extubation decisions. 3, 4, 5 These studies show that higher cumulative epinephrine doses during resuscitation correlate with worse neurologic outcomes, but this does not directly inform extubation timing in stable patients on low-dose infusions.
Practical Algorithm
If this is end-of-life care:
- Discontinue epinephrine infusion first. 1
- Ensure adequate opioid coverage for anticipated dyspnea (morphine 2 mg IV bolus for opioid-naïve patients, titrated to effect). 1
- Have sedatives available (midazolam 2 mg IV bolus) only after pain and dyspnea are controlled with opioids. 1
- Proceed with extubation once comfort is ensured at each step. 1
- Have inhaled epinephrine available for post-extubation stridor if needed. 1, 2
If this is standard extubation in a patient expected to survive:
- The patient should be weaned off vasopressor support before extubation is considered.
- Ongoing need for epinephrine suggests the patient does not meet hemodynamic stability criteria for safe extubation.
