ASA 3+ work up
The ultimate goals of preoperative medical assessment (ASA 3+ workup) are to reduce the patient’s surgical and anesthetic perioperative morbidity or mortality, and to return him to desirable functioning as quickly as possible. It is imperative to realize that “perioperative” risk is multifactorial and a function of the preoperative medical condition of the patient, the invasiveness of the surgical procedure and the type of anesthetic administered. A history and physical examination, focusing on risk factors for cardiac and pulmonary complications and a determination of the patient’s functional capacity, are essential to any preoperative evaluation. Laboratory investigations should be ordered only when indicated by the patient’s medical status, drug therapy, or the nature of the proposed procedure and not on a routine basis. Persons without concomitant medical problems may need little more than a quick medical review. Those with comorbidity should be optimized for the procedure. Proper consultations with appropriate medical services should be obtained to improve the patient’s health. These consultations should ideally not be done in a “last second” fashion. The preoperative preparation involves procedures that are implemented based on the nature of the expected operation as well as the findings of the diagnostic workup and the preoperative evaluation.
