What Happens During Cardiac Bypass Surgery?

Read Transcript

In order to perform a triple by-pass, we have to first take the patient's heart out of circulation. We have [xx] to re-route blood around the damaged area of the heart. That is [xx] that we can use to bypass your heart. We put a little blue line on it so we don't twist it, we twist the vein like this [xx].

You don't want to have, to kill a patient when the blood[sp?] is flowing back, it stays twisted. That has happened to people. That kills you, cause your blood goes through it too. You're going to make sure you straight of time [xx]. They have a lot of flow in them and we're going to put the patient on the heart lung machine.

Okay. [xx] bypass please. Throw in a bypass. A heart lung bypass machine creates an artificial circuit of blood flow outside the body while the heart is being repaired. Heart surgeons connect tubes to major blood vessels detouring blood into a container. An oxygenater acts like the lungs and constantly replenishes the blood with fresh oxygen.

The newly oxygenated blood is picked up the pump which acts like the heart sending blood back to the rest of the body. So while the heart and lungs are bypassed, the cells in the body still get the oxygen and nutrients they need to stay alive. Once the bypass machine has been activated, it's time to temporarily stop the heart from beating.

We going to put a needle in the heart in order stop it now. The solution in the needle is potassium chloride, a paralyzing agent that stops the heart. You'll see up the red line there, that's the critical definition of death. The patient's life is now 100% supported by the bypass machine.

Alright, now the heart operation start. You just put a hole in the aorta on purpose, so you can sew the vein exactly [XX].Now I'm taking the harvest vain and [xx] the tip so that I can marry it to the opening that I just made in the artery. This is the definition of bypass. So have you injected till it's filled up nicely slowing it very nice down this artery where we just put the bypass there.

Soon the blood will be able to flow past the damaged areas of the heart. After working furiously against the clock, the heart has been starved of blood for almost an hour, it's crucial we start the heart now. The longer the patient is on bypass the higher her risk of death. We're about to restart the heart.

The heart must remember to beat on its own. Wipers off. This is the moment between life and death. Grab that all the way head down. This is the moment of truth. Let's give a little time. You see that? So we can electrically stimulated to [xx] the healing. There you go, pop, now it's picking up on its own.

It knows the beat, but you've got to remind it from the very beginning it's a little bit of an issue. So far it looks pretty good you're never out of the woods until the patient wakes up all the way, I'm encouraged, very encouraged.
