Useful Information

Analgesia

All of our veterinary patients deserve an appropriate level of analgesia for their particular condition and/or surgery. There’s loads of good options available, and thankfully they have been very well documented by the Veterinary Anaesthesia and Analgesia Group for quick, easy and reliable reference (it is run by Robert Stein who is a Diplomate of the American Academy of Pain Management, and moderator of the VIN anaesthesia and analgesia message boards).

Fentanyl patches are commonly used, and are fairly effective for most patients for post-operative pain. For more information, click here.

Morphine ketamine and lignocaine (MLK) constant rate infusions (CRI) are very easy to set up, and offer the advantage of being able to titrate them to effect, as opposed to epidurals, which tend to require more post-operative nursing care and carry some degree of risk. Below are some user-friendly spreadsheets that help to calculate the doses required – take care to use the correct spreadsheet that corresponds to the concentration of morphine that you stock. You can adjust the volume of the diluent to suit a syringe pump (20ml or 50mL syringes) or a standard fluid pump (500mL or 1000mL bag of fluids). Adjust the fluid delivery rate in the sheet to give about 6-8 hours of analgesia, so you can effectively keep your patient comfortable over the course of the day. You can slowly turn down the delivery rate to wean them off it and provide a smooth pain free recovery from surgery. This works out to be about 2.5mL/h for a 20mL syringe, 6mL/h for a 50mL syringe, and 125mL/h for a 1L bag in a standard fluid pump (don’t forget to accommodate for this volume in calculation of total hourly fluid rates).

Monitoring

Orthopaedic procedures tend to take a bit longer than routine electives like desexings, and need an anaesthetic chart to record all of the patient monitoring over a longer period. This anaesthetic chart is very comprehensive and covers up to 4 hours on one page. Feel free to download and use it. Its free and saves trees, so why not?!
