Can anesthesia cause bleeding?

Why do I bleed after an operation?
After surgery, it is common to have some minor bleeding from the cut (incision) made by your doctor. But problems may occur that cause you to bleed too much. An injury to a blood vessel can cause bleeding after surgery. Other causes include medicines such as aspirin or anticoagulants (blood thinners).
What causes excessive bleeding during surgery?
Surgical causes are primarly inadequate technical haemostasis. Anaesthetic causes may include too light a depth of anaesthesia, hypercarbia, hypoxaemia, inappropriate posturing of the patient, and venous obstruction. Haematological causes may be consequent to blood transfusion, fibrinolysis or platelet dysfunction.
What happens if you lose too much blood during surgery?
If too much blood volume is lost, a condition known as hypovolemic shock can occur. Hypovolemic shock is a medical emergency in which severe blood and fluid loss impedes the heart to pump sufficient blood to the body. As a result, tissues cannot get enough oxygen, leading to tissue and organ damage.
