Blood Gas Analysis: The Behind-the-Scenes Look into Your Patient

Posted by Abby Crimm

What kinds of tools and assets is your practice using to monitor patients during anesthesia? Is there more you could do to ensure an optimal patient outcome?

Sometimes, just saying the phrase “blood gas analysis” makes some veterinary professionals tense up. The reason it may cause your blood pressure to spike is that we usually run blood gas analyses during high-stress cases when a patient is in trouble.

Amanda Shelby, a veterinary technician specialist in anesthesia and analgesia, in this Quick Cup of Knowledge interview recognizes that although blood gas analysis can be intimidating, it adds tremendously to the overall knowledge we have of a patient. What you usually see on the monitor is just the tip of the iceberg.

Why Blood Gas

When monitoring a patient, what you see on the screen is a relatively surface-level view of how your patient is doing. An analysis of blood gas gives you a “behind-the-scenes view” of what is happening at the cellular level.

It’s worthy to note that in critical patients, there could be discrepancies between what you see on the screen and the results of the blood gas analysis. Because the analysis is more in-depth and precise, it allows you to look at the whole picture and take the indicators on the monitor in context.  

Blood gases provide more accurate information about acid-base and oxygen status than the chemistry panel. In the past, blood gas analysis and interpretation was generally done in universities and large hospitals because the technology wasn’t cost-effective for private practices.

Ms. Shelby believes that today, the availability and relatively inexpensive units used for blood gas analysis make it an investment worth making.

Most Critical Tools

For practices or individuals looking to add blood gas analysis to their portfolio of patient monitoring, we recommend reaching out to the company you get your blood chemistry service from. They most likely have a blood gas analyzer you can use.

Apart from that, all you’ll need are lithium-heparin syringes and someone who is practiced in hitting arteries. Collecting venous rather than arterial blood can lead to inaccurate results.

What Kinds of Cases Need Blood Gas Analysis?

Practices that take more high-risk cases or a heavy critical care load will definitely benefit from routine use of blood gas analysis as part of the monitoring protocol.

For example, where blood-gas analysis is especially useful are critical cases like primary or secondary respiratory disease with oxygenation treatment, septic abdomen, and pneumonia.

Even with the simplest equipment, like a thermometer and a stethoscope, there’s no replacement for a person monitoring the status of a patient under anesthesia.  Whether or not your practice decides to include a blood gas analyzer in your toolbox, the most important thing a practice can do for patients when it comes to pain management, according to Shelby, is a dedicated and caring anesthetist.
