About 150 years ago, it was thought that the only way for a patient to avoid complications during surgery was to completely starve and dehydrate the body. As with many topics, knowledge and research on this has progressed over the last 150 years. But, some doctors still use this method because it is easier for them to implement.
It was true 150 years ago and it's true today that your stomach should be free of solid foods, milky beverages, protein, fat and colored dyes found in sports drinks. These can put you at risk for serious complications during surgery.
Drinking clear liquids is safe up to 2 hours before surgery. ClearFast PreOp® clears from the stomach within 90 minutes, ensuring you have an empty stomach at the time of your procedure.
Not only is ClearFast PreOp® safe to drink before surgery, it's actually safer to drink a clear liquid before surgery than to have a stomach full of acid at the time of your procedure.
ClearFast PreOp is specially formulated for patients who are undergoing general anesthesia or IV sedation, for all surgical procedures from orthopedic to cardiac… from gynecologic to neurologic. It is also appropriate for patients having colonoscopies, oral, and cosmetic surgeries plus cardiac catheterizations, etc.
ClearFast PreOp is ideal for consumption after surgery for patients who cannot or do not want to consume solid foods. If your doctor has directed you to not consume solid foods after surgery, please consult with him/her about how best to use ClearFast PreOp as a meal replacement or supplement.
For children weighing under 50 kilograms or 110 pounds, we recommend dividing the full 12 ounce bottle into 3 servings (4 ounces each.) Children should consume the first two servings at 4 and at 3 hours before surgery and the last serving 2 hours prior to surgery in order to ensure proper absorption before the start of anesthesia.
A 40-50 kg adult could have the same ingestion schedule as a similarly sized child, that is, three servings of 4 ounces each at 4, 3 and 2 hours prior to surgery.
