Is there any blood substitute

Answer 1

If you meant "is it possible to exchange all the blood with any substitute?" - then "no. that's impossible".

But probably you didn't mean that - would be crazy.

If your looking for some substance to substitute blood during a surgery, i.e. to avoid blood transfusion (as it is always a risky thing)... then yes. High tech hospitals are already doing surgeries without real blood. The problem is the quantity that can be substituted by the specific substances... density, osmolarity... (they check those properties).

So... please check some medical information sites or whatever... I know it exists for sure... those hospitals are really modern (and maybe very few). But don't let anyone tell you there wouldn't be any at all... there has been an international special medical convention in Geneva (Switzerland) about surgeries without blood and blood substitutes. Good luck.

Answer: Some of the Methods

Fluids: Ringer's lactate solution, dextran, hydroxyethyl starch, and others are used to maintain blood volume, preventing hypovolemic shock. Some fluids now being tested can transport oxygen.

Drugs: Genetically engineered proteins can stimulate the production of red blood cells (erythropoietin), blood platelets (interleukin-11), and various white blood cells (GM-CSF, G-CSF). Other medications greatly reduce blood loss during surgery (aprotinin, antifibrinolytics) or help to reduce acute bleeding (desmopressin).

Biological hemostats: Collagen and cellulose woven pads are used to stop bleeding by direct application. Fibrin glues and sealants can plug puncture wounds or cover large areas of bleeding tissue.

Blood salvage: Salvaging machines recover blood that is lost during surgery or trauma. The blood is cleansed and can be returned to the patient in a closed circuit. In extreme cases, liters of blood can be recovered using such a system.

Surgical tools: Some devices cut and seal blood vessels simultaneously. Other devices can seal bleeding on large areas of tissue. Laparoscopic and minimally invasive instruments allow surgeries to be performed without the blood loss associated with large incisions.

Surgical techniques: Thorough operative planning, including consultation with experienced clinicians, helps the surgical team to avoid complications. Prompt action to stop bleeding is essential. Delays greater than 24 hours can greatly increase patient mortality. Dividing large surgeries into several smaller ones decreases total blood loss.

You can find much information on Jehovah's Witnesses official website. Working with Jehovah's Witnesses, many hospitals all over the country have developed a Bloodless Medicine Program and Department. Englewood Hospital snd Medical Center, Englewood, New Jersey is the frontrunner.
