Comfortable with G-tubes, tracheostomies, and VP shunts?

Good.

Get ready for the next level: Vagus Nerve Stimulators, Intrathecal Pumps, and Ventricular Assist Devices.

Details in Audio:

Vagus Nerve Stimulators

For intractable epilepsy; sends retrograde signal up corona radiata

Also may be used in: depression, bulimia, Alzheimer, narcolepsy, addiction, and others

VNS magnets

Are VNS safe in MRI?

Are VNS safe in everyday life?

Intrathecal Pumps

Used to infuse basal rate of drug, usually baclofen for spasticity, but pump may contain morphine, bupivicaine, clonidine. Also used for severe MS, stroke, TBI, chronic pain. Verify the medication and identify the toxidrome if symptomatic.

Ventricular Assist Devices

May be left ventricular assist, right ventricular assist, or biventricular assist device.
