A nurse will collect information about your health, fitness, previous operations, allergies and more in order to individualize your care to your specific needs. It helps prepare the surgeon, the anesthesiologist and you by identifying any potential anesthetic, surgical or post-operative complications. You may also undergo an electrocardiogram (ECG), blood or urine tests or other tests. The assessment length varies depending on the type of operation that you are having.
