## What is Coexisting Diseases & Surgery?

The Vargo Coexisting Diseases & Surgery App is a clinician-built resource designed to help anesthesia providers tailor anesthetic management to the patient’s underlying comorbidities and surgical considerations. Built from years of clinical experience, the app focuses on how coexisting diseases directly impact perioperative decision-making.

Organized by major clinical systems, the app allows for rapid access to condition-specific anesthesia considerations—whether preparing for a case or managing complex patients in active clinical settings.

The app is structured by major organ systems and disease categories, providing focused anesthesia guidance across a wide range of conditions:
- Brain / Neuro
Neurologic conditions and their impact on anesthesia management
- Cardiac
Hemodynamic considerations, cardiac pathology, and perioperative risk
- Endocrine
Diabetes, adrenal disorders, thyroid disease, and metabolic implications
- Gastrointestinal
GI disorders affecting anesthesia planning and intraoperative care
- Hematologic Disorders
Coagulopathies, anemia, and blood management considerations
- Liver & Biliary Tract
Hepatic dysfunction and implications for drug metabolism and coagulation
- Pediatrics & OB/GYN
Specialized considerations for pediatric and obstetric populations
- Pulmonary
Respiratory disease management and ventilation strategies
- Renal Diseases
Kidney dysfunction and fluid, electrolyte, and drug considerations
- Congenital Heart Defects
Structural cardiac conditions and tailored anesthesia approaches

The app is built to provide clear, focused guidance that directly applies to clinical practice:
Organized for rapid navigation by system and condition
Emphasis on how disease states influence anesthetic planning
Practical, case-driven considerations rather than general summaries

This is a tool designed to help providers quickly answer the question:
“How does this patient’s condition change my anesthetic plan?”

The Vargo Coexisting Diseases & Surgery App is developed by experienced anesthesia providers who specialize in managing complex cases across a wide range of disease states. The content reflects real clinical decision-making and is continuously refined to remain relevant and practical.

All future updates and additions are included with a one-time purchase. There are no subscriptions or recurring fees.

Designed for every level of the anesthesia care team.

Not just what to do—but the physiology driving every decision.

### 5/5 — Awesome compliment to Mega App!

*2026-05-24*

The Vargo Coexisting Diseases & Surgery App feels like an extension of the Vargo Anesthesia Mega App — another powerful resource for SRNAs and anesthesia professionals looking for fast, organized, clinically relevant information before a case.
The app covers an extensive range of coexisting diseases, surgical procedures, and perioperative considerations in a way that is easy to navigate and practical for everyday anesthesia practice. The layout is clean, intuitive, and designed for quick access when reviewing cases or studying.
The search function is fast, the organization makes sense, and the references throughout the app add another level of credibility and depth to the content.
What also stands out is the commitment to continual updates and improvements. New material and features are consistently added without subscription fees or recurring costs.
Whether you’re an SRNA preparing for clinicals or a practicing CRNA looking for a reliable anesthesia reference, this app quickly becomes something you reach for regularly. Highly recommended for anyone in anesthesia training or practice.

### 5/5 — Pleasantly surprised

*2026-05-24*

I bought this app a long time ago along with the Vargo Anesthesia Mega App when the company had their annual sale.  I was pleasantly surprised yesterday when I pulled up the Coexisting Disease App looking for info on my surgery/anesthesia patient with a rarer disease.  This app was very detailed and had everything I needed to know to prepare for this patient…highly recommend!
I also used this app quite a bit as an anesthesia resident!

### 2/5 — Not as helpful, missing surgery procedures

*2022-12-09*

Get the mega app over this firstly, this is very supplemental. Missing some specific surgeries like the Ivor Lewis Esophagectomy. I had to google it, having this just feels like a more “for fun” thing rather than a strong educational tool.

**Developer response:** We are wondering if this person was a little confused while writing this review, or obviously didn't know the differences between the two Vargo Apps.  
The person stated, "Get the Mega App over this firstly, this is supplemental."
The (17 apps in 1 app) Vargo Anesthesia Mega App has an extensive app, "Case Tips" for surgical procedures...step by step.
The "Ivor Lewis Esophagectomy" is a type of transthoracic esophagectomy.
Please refer to "Esophagectomy-Transthoracic" in the Vargo Anesthesia Mega App.

This review is for the Vargo Coexisting Diseases & Surgery App.  This comprehensive app aids the anesthesia provider in anticipating and individualizing their anesthesia management with the patient's coexisting diseases or comorbidities.  Preoperative patients with Sickle Cell Disease, Angioedema, Congenital Heart Defects, Cystic Fibrosis, Pulmonary HTN, and Multiple Sclerosis are just a few examples in this app.  The pathology is very detailed in this app...approximately the size of a 5,000+ page text book. 
We welcome and encourage this person to reach out to us for further information.

### 5/5 — Another Great Anesthesia Resource

*2022-11-21*

Vargo did another excellent job with this app. 

Every anesthesia resident and practicing anesthesia provider would benefit from having this app. It contains a wealth of information, is an extensive reference textbook of pathologies with pertinent information related to anesthesia.

### 5/5 — ANOTHER MUST-HAVE FOR SRNAs!

*2022-10-04*

This app is like stumbling on a second gold mine for SRNAs after finding the first (The Vargo Anesthesia App). It gives you information for pretty much anything you could want to look up regarding your case. 

Just like the Vargo anesthesia app, the user interface is clean, neat, and organized. It has a search feature that is quick to display results, and it has tabs that allow for ease of finding what you want. All information included also has APA- cited references at the bottom, too, just like the Vargo app. Outstanding. 

This app is also frequently updated with new information or other features to make a continuously better experience for you. Plus, no additional monthly subscription fee and no data tracking. 

Overall, it is an amazing app on your phone.  It’s something you will use in school and as a CRNA, so 100% worth it. I would highly suggest this app for all SRNAs!

### 5/5 — A great resource!

*2022-05-06*

10/10 would recommend. A great resource to have at your fingertips.

### 5/5 — Great anesthesia app!

*2022-03-12*

Matt Vargo has created something truly unique here. So many organized categories with all the pearls you need. I suggest his Mega App and Coexisting app as well.

### 5/5 — Extremely useful

*2021-10-26*

A great app to help increase your knowledge as an SRNA or CRNA!

### 2/5 — It’s ok

*2021-05-10*

Missing information especially conditions like anxiety and depression. No mental health conditions noted sadly.

**Developer response:** They will be added. 
The app presently has over 4,000 pages and growing. 
Thank you for your input.

### 5/5 — PA Queen

*2021-01-31*

I love this app. 
It has so much material on diseases alone.
The material added about surgical concerns and anesthesia plans does not pertain to me.
However, most of the material is on detailed pathophysiology and medications for diseases- which I like.
Easy to understand user friendly.
The best part is it’s only a one time purchase !!!!
