Fluid Therapy Intra-operatively
While your pet is under anesthesia, a variety of effects are produced from the anesthetic drugs and surgical procedures. These effects include low blood pressure, decreased blood flow to the kidneys and other organs and water loss.
The benefits of fluid replacement while under a general anesthetic include the following: faster recovery times, preventing dehydration, decreasing the risk of low blood pressure, maintaining organ function (especially kidneys), clearing the anesthetic drugs from the system and having intravenous access in the case of an emergency. For younger, healthy animals, intravenous fluids while under surgery are considered optional, but for animals over the age of 7, or with a concurrent medical illness, intra-operative fluids are required.
