ELI5- How do surgeons sew up after an operation without leaving air in the body?
In: 46
Lots of times some air IS left in the body.
Surgeons usually work through the smallest hole that will give access to the anatomy, so people aren’t USUALLY laid wide open as you might think, and body parts fit together nicely, so they go back into their original positions fairly easily. But, air does get into body cavities, sometimes on purpose, and even just big incisions like a hip replacement usually have trace amounts of air trapped while they close and suture.
I can often see air when I take post-op x-rays.
