After 4 years of traveling between Harvard/MIT and Stanford and 200 pages of utter despair aka my thesis, I have officially defended my PhD in Medical Engineering and Medical Physics through the Harvard/MIT Health Sciences and Technology Program!

Excited to share a new perspectives piece on AI in surgery! Instead of making every surgeon an AI expert, we centralized risk assessment to a small team & screened 2200 GI patients, moving AI from proof-of-concept to real clinical workflows. Read it here: journals.lww.com/aosopen/ful…

Happy Holidays from the Purdon Lab!
As we wrap up the year, we’re grateful for the collaborations, progress, and community that made this such a meaningful year for our lab. We’re excited to share a few highlights from the past months and to look ahead to what’s coming next.

Excited to share a new important paper about peripheral nerve blocks: while they reduce pain and opioid use right after surgery, they may lead to up to 22% more opioid use later during the hospital stay, likely due to rebound pain.

What started out as a side project to teach one of my research assistants about clinical machine learning and statistics has turned into a full publication in @BJAJournals!

Can brain waves during surgery predict who’s at higher risk after?
What’s going on:
Every year, millions of people die after surgery. Doctors need better ways to spot who’s most at risk—while the surgery is happening.

We are excited that Mae’s case report has been published!
Here we show that anesthetic-induced neural signals from EEG can be used as a direct measure of an Alexander’s Disease young patient’s anesthetics sensitivity. pmc.ncbi.nlm.nih.gov/article…

We are excited about the possibility of using EEG monitoring to increase system-wide efficiencies in OR scheduling, PACU resources, and both patient and caregiver satisfaction! (4/4)

Application of EEG monitoring decreased anesthetic wash-off and PACU recovery times by 50%!
Overall, this case highlights the potential benefits EEG monitoring could provide our pediatric patients and clinical staff with almost no additional changes to anesthetic workflow. (3/4)

Rather than relying on anesthetic dosing schemes that are based on adult physiology and don't account for changes to anesthetic sensitivity associated with neurodegenerative disorders, the EEG can provide real-time feedback to minimize anesthetic exposure and improve outcomes.

We have officially started collecting data on our Awake EEG and Aging Study which looks at EEG brain activities associated with aging and preclinical Alzheimer's!
Here is the study design poster that Amber and Julia presented at the Stanford Anesthesia Department Retreat

Excited that my first 1st authored paper from my PhD research has been published in Anesthesiology!
We found that neural oscillations in the alpha band of frequencies (8-12 Hz) during anesthesia can predict the risk of postop mortality up to a year after surgery. 🧵 (1/3)

Excited that our case report has been published!
Here we show how the neural signals from a readily available forehead EEG sensor can be used to titrate anesthetic dosing for a child with neurodegenerative disease and decrease postop recovery times.

Enjoying our @UWAnesthPainMed 16th Academic evening in the beautiful UW WƎⱢƎBʔALTXʷ – Intellectual House: a huge display of the rich science that our departmental members pursue in biomedical & clinical sciences. Our 🔑 note speaker is Dr. Patrick Purdon from @stanfordanes

In the reviewed preprint, we propose a Oscillation Component Analysis (OCA) approach, in analogy to Independent Component Analysis (ICA), in which source separation is achieved through biophysically inspired generative modeling of neural oscillations. doi.org/10.7554/eLife.97107.…

Although we demonstrated several utilities of the methods, the reviewer (correctly) pointed out lack of empirical evidence for the approach's advantage.

Currently, we are working on gathering such empirical evidence in response the the reviewer's comment.
