8 Ways to Make Veterinary Anesthesia Less Scary

No other part of your job should be more rehearsed, studied, and in tip top shape than your anesthetic monitoring skills. In the past we've mentioned lazy anesthetists and doubling up with monitoring and dental cleanings, but let's focus now on the priority: the patient. Here are basic ways to improve patient care under anesthesia and make the entire experience less stressful for everyone.

 

1. Diligence with vitals

Monitoring anesthesia 101 will tell you that in most cases a patient's temp will drop along with their blood pressure. Instead of waiting for the inevitable, have warm bags of fluids/blankets/bair hugger all ready to use. Be prepared to increase the fluid rate or do closely monitored boluses when the blood pressure plummets. Actively keeping the patient warm during surgery will make a huge difference post-operatively and will prevent scrambling to keep them warm during recovery. And make sure you're recording vitals accurately!

 

2. Understanding O2 and gas anesthetic rates

Before cranking up the isoflurane because a patient seems light, check your tube and 02 rate first. If you are struggling to keep a patient in the proper anesthetic plane, likely you need to do more troubleshooting. Check to make sure the ET tube is properly placed and inflated without leaking. Next, check your 02 rate. Oxygen carries the isoflurane into the patient's body and simply increasing the rate can delivery the anesthetic more efficiently. Still having problems?

3. Having a properly functioning and maintained anesthetic machine

All parts of your anesthetic machine and equipment must be properly maintained. You should check for leaks, clean the circuit and maintain proper levels of Sodasorb daily. Take a minute to read the manual for your machine and the manufacturer recommendations. They usually have a method to their madness, so follow the instructions closely. Also, make sure you are choosing the proper type of breathing circuit for your patient as this could affect how well they do under anesthesia. Smaller patients (<7kg) will benefit from a non-rebreathing circuit. 

 

4. Using proper analgesics/multi-modal pain control

Pain control can really make a difference pre-operatively for a patient under anesthesia. It's a known fact that it's easier to prevent pain than to try to catch up to it after wind-up has happened. Just because your patient is under anesthesia doesn't mean they are not feeling the pain. Using proper pre-op and intra-op analgesia is not only gold standard for care, but will make for a much smoother anesthetic ride for you.

5. Proper ventilation

All inhalant anesthetics and injectables have an effect on the respiratory action of the patient. Be sure not to just watch the reservoir bag but assess the chest excursion as well. During the surgery process, the clinician can cause the reservoir bag to appear to be moving as if a breath has been exchanged, so hands or eyes on the chest of the patient is advisable to truly know the rate and quality of the breath.  Remember: the quality of the breath is just as important as the rate of the breath. If you do have a patient getting light, who is taking shallow breaths, taking over their breathing for a few minutes will allow you to smooth out the patient's plane of anesthesia without having to increase your inhalant which can cause other intra-anesthesia complications.
 
 

6. Emergency drugs

It's important not only to have your emergency drugs handy, but to have an idea of how much you will need to give your patient. Posting emergency drug charts right in the OR is a great idea, or having them already figured out for your particular patient is even more helpful. Also make sure to have the crash cart nearby, or at least some extra needles and syringes handy along with your emergency drugs right in the OR.

7. Don't rush the extubation process

A particularly sensitive (and potentially dangerous) time during a patient's recovery is the extubation process. It is important that the patient be properly positioned and that they are watched for any signs of regurgitation during the waking stage. Extubating a patient when it is awake and able to swallow, which indicates gag reflex has resumed, is important. Stimulating a patient awake to hurry the extubation can lead to a patient who then will go back into a deep level of sedation to the point where they will lose their gag reflex.  This can lead to aspiration as the patient does not have a guarded airway if they regurgitate. 
 
 

8. Continuing education

Stay up to date with the latest and greatest information regarding patient care under anesthesia. You can find information online and at lectures and conferences. 

Care under anesthesia should always be a top priority. We should continue to keep ourselves educated, on task, and alert with our anesthetized patients.
