Is 900 ml blood loss from surgery a lot?

Yes, 900 ml blood loss from surgery is considered a significant amount and requires immediate medical attention.

The average adult body contains about 4,500 to 5,000 ml of blood. Losing 900 ml, which is approximately 20% of the total blood volume, can lead to hypovolemia, a condition characterized by a critically low volume of circulating blood.

Signs and symptoms of hypovolemia include:

- Confusion

- Rapid heart rate

- Low blood pressure

- Shortness of breath

- Pale or cool skin

- Reduced urine output

- Loss of consciousness

Hypovolemia can be life-threatening if not promptly addressed. Treatment involves intravenous fluid resuscitation, blood transfusion, and correction of the underlying cause of blood loss.

During surgery, efforts are made to minimize blood loss by using various techniques and medications. Still, some blood loss is inevitable. The medical team closely monitors the patient's vital signs and blood loss during and after the procedure to ensure their safety.
