Preoperative

A surgical booking identifies what procedure is planned. The preanesthetic assessment identifies whether the patient’s current health status, medications, airway, fasting status, and treatment preferences permit that plan to proceed safely. The assessment supplies the information required to plan anesthetic management. The preanesthetic record includes relevant medical and surgical history, physical-examination findings, indicated investigations, current and recent medications, unusual drug reactions, prior anesthetic complications, family history of anesthetic adverse reactions, and ASA Physical Status classification. This is not a ritual checklist or a declaration that a patient is “cleared” for surgery. It is a risk-recognition process. A newly reported chest symptom, a dose of anticoagulant taken that morning, or an unclear resuscitation limitation may alter the timing, location, monitoring, anesthesia technique, or appropriateness of the procedure. The experienced nurse notices discrepancies first: the patient says they ate at 0600 although the chart says fasting; a listed “allergy” was actually nausea; the consent names a different procedure from the one the patient describes. A discrepancy is clinical information, not an inconvenience.
