Preoperative care

At some point before the operation, the healthcare provider will assess the fitness of the person to have surgery.

Immediately before surgery the person's body is prepared, perhaps by washing with an antiseptic, and if needed, their anxiety is addressed to make them comfortable.

[2] The available research does not give insight about any differences in outcomes depending on whether a doctor or nurse conducts this assessment.

Screenings which are done without indication carry the risks of having unnecessary health care.

Commonly overused screenings include the following: Among children who are at normal risk of pulmonary aspiration or vomiting during anaesthesia, there is no evidence showing that denying them oral liquids before surgery improves outcomes but there is evidence showing that giving liquids prevents anxiety.
