To needle or not to needle? Maybe you are just getting started on your aEEG journey and researching your equipment needs, or maybe you have an established program and just looking to weigh your options…whether your an aEEG novice or an expert, you’ve probably found yourself asking if your protocol includes the right sensors for your patient population.

Selecting sensors is one of the biggest decisions you’ll make in building a neuromonitoring protocol, but rest assured there is really no right or wrong choice, just options! So let’s take a look at the top two pros and cons of each:

One of the most popular options out there are subdermal needles, ranging in size from 28-30g, these tiny needles slide right under the patient’s skin.

Quick to apply
Low impedance 

Invasive, skin breaking
Risk for staff needlestick

Another option that’s grown in popularity offering an alternative to needle electrodes are hydrogels.  These electrodes are made with a water-based adhesive applied to a fabric electrode patch.

Non-invasive application
Gentle adhesive safe for preemies

Time-consuming application
Require maintenance to maintain signal

Metal cups and disks
Other options are reusable cups and disk electrodes, typically associated with traditional EEG.  

Reusable sensors
Non-invasive technique

Time-consuming application.
Harsh adhesives and glue

There are new sensors on the market too, like the incereb neon, which offers a simplified electrode application with a single electrode array.
