A pre-operative assessment is a health check, usually one to four weeks before surgery, where a nurse or anesthetist reviews your medical history, medications, allergies, and previous reactions to anesthesia. Expect baseline measurements such as height, weight, blood pressure, heart rate, and oxygen levels, plus tests that may include blood work, urine samples, an ECG, chest X-ray, or swabs for MRSA. You will also discuss fasting instructions, which medicines to pause or continue, anesthesia options, and arrangements for your recovery and discharge home. The exact tests depend on your age, existing conditions, and the type of operation planned, so there are several important factors to consider before your appointment. See below to understand more about how to prepare and what questions to ask.
If you have symptoms that are worrying you ahead of surgery, or you are unsure whether a new ache, cough, or fever could delay your procedure, getting clarity early matters because surgeries are often postponed for untreated infections or unmanaged conditions. A free, instant, online symptom check can help you organize what you are feeling, understand possible causes, and decide whether to contact your surgical team before your assessment date.
