What was the survival rate for surgical procedures in ancient times, as microbiology and infection were not understood at that point in time?

I’m a medical student, I was discussing this with a team of surgery Residents today, in context of cesarean sections, which have been around for thousands of years.

What precautions did physicians use to prevent infections, if any? Did they use any form of antiseptic?

Did people go into surgery assuming that they would die?

How Would they suture the incisions, and did the surgical sites always get infected?
Thank you!
