How do they prevent people from bleeding out dry during any major operation?
In: Biology
You’re not just a big balloon of blood that bursts open with a scalpel. Blood is in blood vessels. A surgeon generally avoids cutting through or injuring major blood vessels during surgery, apart from specific circumstances where cutting into those blood vessels is necessary. There’s a little bit of oozing from small vessels but this is fairly little blood loss so it’s usually not a big deal.
If there’s a lot of blood loss, we give blood transfusions.
