Update on preoperative evaluation and optimisation

Abstract

The patients presenting for surgery today often belong to the extremes of age, have multiple co-morbidities, and undergo complex surgeries. This makes them more prone to morbidity and mortality. A detailed preoperative evaluation of the patient can contribute to reducing this mortality and morbidity. There are various risk indices and validated scoring systems and many of them need to be calculated using preoperative parameters. Their key objective is to identify patients vulnerable to complications and to return them to desirable functional activity as soon as possible. Any individual undergoing surgery should be optimised preoperatively, but special considerations should be given to patients with comorbidity, on multiple drugs, and undergoing high-risk surgery. The objective of this review is to put forth the latest trends in the preoperative evaluation and optimisation of patients undergoing noncardiac surgery and emphasise the importance of risk stratification in these patients.
