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.
