In surgery, how do they keep the blood from gushing out?!
Question: In surgery, how do they keep the blood from gushing out.?
So, you know in medical surgery videos, shows, movies, etc., they make a large cut on the stomach, brain, whatever...how can they keep it so "clean" without all the blood rushing out.? Or, how do they keep the blood inside the body.?Health Question & Answer
Answers:
Well, it does ooze out. To keep it from gushing, they avoid cutting into arteries which have blood under pressure. Veins are not under so much pressure so the blood there oozes out. also, blood vessels are clamped or burned (cauterized) to stop bleeding as well as with the application of gauze with anti-clotting chemicals. There is irrigation then suction to remove excessive oozing blood. Your body may also try to stop bleeding by its own clotting and vasoconstrictive mechanisms.
Furthermore, surgery is done in a controlled manner to control bleeding as the surgery proceeds. Sometimes a major blood vessel is accidentally cut and you get a gush, but then the surgeon must work quickly to stop the bleeding. In major heart surgery, a bypass machine is used.
Of course, if there is a major loss of blood, then the patient receives blood transfusions and fluids. Jehovah's Witnesses don't agree to take blood transfusions, so they may die with major blood loss.
On another note,the anesthesiologist can control bleeding a little by keeping the blood pressure down a little or giving blood vessel constricting intravenous medications.
I can tell you that the worse experience I ever had in surgery (assisting) was a patient who had ruptured his abdominal aorta and had alot of bleeding. He died.Health Question & Answer

Avoiding arteries is a must.
If you accidentally hack through one of those, you're gonna get a gusher.
I tell my patients to lay off the aspirin and blood thinners three days prior to surgery.
For extremities (I operate on the foot and ankle), we use a tourniquet. This wraps around the ankle and gets inflated to about 100 pounds per square inch over the patients blood pressure.
We also exsanguinate or "milk out" any pooled blood by wrapping a tight bandage up the leg before inflating the tourniquet.Health Question & Answer

They stick a tube that has suction into the area to suck the blood out when it is too hard to see. Similar to what the dentist uses to clear the saliva out of your mouth.Health Question & Answer
They use medications that slow the blood down. There is still blood, just at a decreased rate

They slow down your heart rate so not so much blood is present. That combined with a suction at the surgical site.Health Question & Answer
