General anesthesia: what it consists of and what are its risks

General anesthesia is a medical procedure used simultaneously with surgery. It can even be said that it makes the surgery easier to carry out. For this, a combination of medications is used that induces a state of unconsciousness, similar to the dream.

This state is induced before surgery, is maintained during the operation, and lasts slightly longer than the procedure. Specifically, it has several objectives; one of them is to prevent the patient from suffering pain during the intervention. On the other hand, it is intended to facilitate the surgeon's work. For this, there is muscle relaxation and control of breathing and vital signs.
