This approach is vital as it prepares the patient for potential surgical intervention, which may be necessary if the upper GI bleeding leads to complications or if the patient's condition deteriorates.

When a patient is at risk for undergoing surgery, it is crucial to ensure that the stomach is empty to reduce the risk of aspiration during anesthesia and to allow for any necessary investigations, such as endoscopy, without interference from food or liquids.
