Preoperative care covers the evaluation and preparation that happen before a procedure. The goal is not to make the process more complicated, but to identify details that may affect anesthesia, surgery, discharge planning, or recovery.

Why preoperative care matters
The period before surgery is often when patients receive the most practical instructions and when the clinical team has the best opportunity to identify issues that need attention. A good preoperative process can reduce avoidable surprises, improve communication, and help patients understand what to expect.
Preoperative care often includes reviewing health conditions, prior procedures, allergies, medications, supplements, tobacco or alcohol use, and previous reactions to anesthesia. The care team may also discuss logistics such as fasting, transportation, and postoperative support at home.
What may happen before surgery
The exact steps vary by procedure and facility, but many patients encounter some combination of medical history review, a pre-op appointment, medication instructions, and individualized testing. Some people may also need input from primary care, cardiology, or another specialist if they have chronic conditions that could affect perioperative planning.
This does not mean that every patient needs a large number of tests or consultations. In fact, modern guidance generally supports targeted evaluation rather than routine testing for everyone. The most useful assessment is the one that answers a real clinical question.
How to get ready for pre-op visits
Bring a current medication list, including over-the-counter drugs, supplements, and vitamins. It is also helpful to know your allergies, prior operations, implant history, and whether you have ever had problems such as postoperative nausea, difficult IV access, or delayed waking after anesthesia.
If you already have recent blood work, electrocardiograms, imaging, or specialist notes, ask whether you should bring them or have them forwarded in advance. Being organized can make the visit more efficient and reduce duplicate testing.
How this section helps you navigate the site
This topic hub groups together the most important pages related to the preoperative period. Start with the broad assessment guide if you want a general overview. Then use the more focused pages for pre-op appointments, testing, and medical clearance questions.
Because the preoperative process overlaps with surgery preparation and anesthesia planning, you may also find it helpful to continue into the surgery preparation and anesthesia sections once you have reviewed the basics here.
Helpful reminder
General online guidance can never replace instructions from your own surgeon, anesthesia team, or facility. If your healthcare team gives directions that differ from a general article, follow your healthcare team.
