Bleeding Postoperative

**Bleeding after surgery** is a violation of the integrity of blood vessels as a result of mechanical, thermal, chemical or radiation trauma to a surgical wound. After surgical interventions, it occurs in 3-7% of patients, usually on the first day after surgery. Postoperative bleeding is divided by origin into primary and secondary, and by severity - into mild, moderate, severe and extremely severe. Most often, their cause is specific reasons not related to the specifics of the operation itself, but the source is nosological forms of acute peritonitis.
