Safer Surgery for Dogs Begins with Predictive Blood Pressure Monitoring
Human medicine has made remarkable advances in areas where veterinary care for dogs is still catching up. Not because progress isn’t possible—but because these questions haven’t yet been studied.
How anesthesiologists predict dangerous drops in blood pressure that occur during surgery is one of those gaps.
Why Does Blood Pressure Dip During Surgery?
Hypotension is the medical term for when blood pressure drops too low. It means that blood isn’t flowing with enough force to reach vital organs. Steady, continuous blood flow is essential for life, as it delivers oxygen to every part of the body while removing waste products and toxins.
The consequences of dangerously low blood pressure can be severe: organ stress, kidney injury, heart problems, neurological complications, and, in the worst cases, death.
During surgery, drops in blood pressure occur because anesthesia can alter heart and blood vessel function, and the drugs used during anesthesia can further lower blood pressure as a side effect.
Add in factors like blood loss and dehydration during surgery, the type of surgical procedure, and the dog’s size, age, or body composition, and it’s easy to see how even healthy dogs can face dangerous drops in blood pressure on the operating table.
Hypotension can develop suddenly and take time to reverse, so even dogs initially doing well under anesthesia may leave little time for intervention.
A Lesson from Human Medicine
Imagine a patient’s blood pressure dropping during surgery; sometimes just a few moments can make all the difference.
In human medicine, new devices and technologies are helping anesthesiologists stay one step ahead. Smart sensors, predictive algorithms, and machine learning now not only track blood pressure in real time but also predict and alert clinicians to early warning signs before things become dangerous.
With these advances, doctors can anticipate changes and proactively adjust fluids or medications in real time—helping prevent complications like sudden drops in blood pressure before they even occur.
For human patients, this technology has been nothing short of lifesaving.
For dogs, however, predictive tools like this are not as available.
From Human Health to Dog Health
That’s the gap Dr. Hisashi Sakata set out to address.
At Colorado State University, Dr. Sakata, a veterinary anesthesiologist, has devoted his career to being the quiet hero in the operating room, making anesthesia safer and giving animals a better chance at smooth, successful recoveries from surgery.
In 2024, with support from the AKC Canine Health Foundation, Dr. Sakata launched an exciting new study.
Inspired by breakthroughs in human medicine, he wanted to see whether a new smart device for humans, using advanced algorithms and real-time monitoring, could reliably predict drops in blood pressure in dogs during surgery before they happen.
His big question: Could this tool give veterinarians early warning, helping them adjust care on the spot and keep dogs safer during surgery?
Why This Research Matters So Much
If successful, this research could transform veterinary anesthesia. Instead of responding after a dog’s blood pressure dips, veterinarians could anticipate drops, intervene early, reduce organ stress, and improve recovery.
The impact is even greater in veterinary medicine, where a single veterinarian may be responsible for both surgery and anesthesia.
For any dog undergoing surgery, that difference could be profound.
The Bigger Picture
Dr. Sakata’s work highlights a bigger truth: dogs face many of the same medical risks as humans, but veterinary care often falls behind because research funding is far more limited.
By adapting proven innovations from human medicine, researchers are helping close this gap so dogs no longer have to wait for the advanced, life-saving care they deserve
Thanks to donors like you, that gap is closing—one breakthrough at a time.
