Anaesthesia.
Prior to anaesthetizing an animal it is wise to run a basic blood profile. Certain drugs will have an unpredictable result when administered to a compromised patient.
There are three main systems to be aware of prior to inducing GA.
• Cardio-pulmonary system. The heart and lung efficiency will be assessed by the vet.
The liver – which will excrete chemicals in the body.
• The kidneys which help the removal of waste/toxins filtered from the liver to be excreted from the body. If the kidneys are not functioning well the toxins which build up can damage other organs such as the heart, liver and brain.
Here is a guide to interpreting those blood results.
• ALKP/ALT = Raised levels can mean liver disease.
• Creatinine = High levels show kidney cell damage.
• Urea = High levels of this nitrogenous waste shows the kidneys are not working effectively as they have built up and not been excreted. When compared with Creatinine the amount of kidney damage can be assessed.
• Glucose = high levels can be a result of stress or diabetes.
• Albumin = a term for a group of proteins. High levels with other clinical signs can indicate certain dieases.
• Bilirubin = a bile piment which causes jaundice.
• Amylase = a pancreatic enzyme which raised levels can indicate pancreatitis.
• Calcium = is essential for bone and muscle strength – high or low levels can have a dramatic effect on the body. Also certain conditions can be diagnosed such as eclampsia.
Most practices offer a pre-anaesthesia profile for all operations – this is generally a six slide biochemistry and a pcv test. Do you recommend to all of the clients you see when admitting an animal? Do you feel it is necessary for a young, fit, healthy animal that has come in for routine neutering for example. Please post your replies in the nurse’s forums.
