It is your choice whether you opt for fluids during the surgery for your pet. We definitely recommend it for surgeries lasting longer than 45 minutes. IVF helps maintain optimal blood pressure, helps perfuse the kidneys and ensures a quicker post op recovery. If your pet’s blood pressure drops suddenly during an anaesthetic, we recommend IVF. If you decide on IVF for your pet, they are placed on fluids before their anaesthetic and taken off fluids just prior to discharge.
