From the Guidelines
Long-term use of vasopressors is concerning due to potential risks of intense vasoconstriction, increased myocardial O2 consumption, and lack of improvement in long-term patient outcomes.
Key Concerns
- Intense vasoconstriction: Vasopressors can cause intense vasoconstriction, which may lead to decreased perfusion of vital organs 1.
- Increased myocardial O2 consumption: Vasopressors can increase myocardial O2 consumption, which may be detrimental in patients with cardiac dysfunction 1.
- Lack of improvement in long-term patient outcomes: Despite short-term benefits, vasopressors have not been shown to improve long-term patient outcomes, including neurologically intact survival 2.
Specific Vasopressor Concerns
- Norepinephrine: While norepinephrine is the first-line vasopressor agent, its long-term use may be associated with increased risk of tachyarrhythmias and arrhythmias 3, 4.
- Epinephrine: Epinephrine may be associated with increased risk of tachyarrhythmias and arrhythmias, and its use has not been shown to improve long-term patient outcomes 1, 2.
- Dopamine: Dopamine may cause more tachycardia and arrhythmias than norepinephrine, and its use should be limited to highly selected patients 3, 4.
Clinical Considerations
- Monitoring and titration: Close monitoring and titration of vasopressors are essential to minimize risks and optimize benefits 3, 4.
- Alternative therapies: Alternative therapies, such as dobutamine and high-dose insulin, may be considered in specific clinical scenarios 4, 5.
- Individualized care: Vasopressor therapy should be individualized based on patient-specific factors, including underlying cardiac function, renal function, and risk of arrhythmias 3, 4.
From the Research
Concerns for Long-Term Use of Vasopressors
The long-term use of vasopressors can have several concerns, including:
- Risk of tissue extravasation associated with peripheral vasopressors, which can be life and limb threatening 6
- Potential for worsening organ perfusion and resulting in increased mortality and organ failure in hypotensive trauma patients 7
- Risk of patient harm due to misuse and errors in the preparation and administration of bolus-dose vasopressors 8
- Need for careful consideration of the clinical use of vasopressors in various shock states, including practical considerations and innovations in vasopressor administration 9
- Importance of understanding the pharmacology and clinical profile of every single vasopressor substance, as well as the fundamentals of vascular physiology and vasotonic regulation, to safely provide vasopressor-based therapies 10
Clinical Considerations
When using vasopressors, it is essential to consider the following:
- The clinical setting and the specific type of shock being treated 9
- The potential benefits and risks of vasopressor use, including the risk of tissue extravasation and patient harm 6, 8
- The need for careful monitoring and management of patients receiving vasopressors, including monitoring of blood pressure, organ perfusion, and potential adverse events 9, 6
- The importance of targeting an appropriate balance between intravascular volume and vascular tone in the resuscitation of traumatic shock 7
