Benefits Of A Ventricular Assist Device?
Main indication for Ventricular Assist Devices (VADs)
Three different Types of VADs
Indication for Long Term Intracorporeal VAD?
What is a Internal Catheter VAD?
(Impella Cardiac Assist Device)
How does an Internal Catheter VAD work?
What is an Extracorporeal VAD (Tandem Heart)?
How does Extracorporeal VAD (Tandem Heart) work?
Anesthetic Implications For Patients With VADs (7)
- Arterial line is required
- MAP is commonly used to trend blood pressures
- MAP should be AT LEAST 60mmHg - Patients are usually on anticoagulants
- Patients are considered full stomach, and an RSI is indicated
- Electromagnetic Interference (EMI) can alter device function
- Bipolar cautery is more likely to be used - Patients are more susceptible to infection due to the direct route from the driveline to the body
- Chest compressions are controversial
- Some say it can dislodge the device, others say it is needed because the patient will not survive otherwise
Anesthetic considerations for a VAD Monitor
- Identify and talk to the VAD team! (if the hospital has one)
- Secure a reliable power source for the VAD
- Establish a safe coagulation plan with the surgeon & cardiologist
- Hemodynamic stability is crucial
- 4a. Maintain preload (avoid hypovolemia), because pump flow decreases when preload decreases
- 4b. Avoid hypertension, because increases in afterload can cause a decrease in the output of the device
