What are the recommended pre-surgery guidelines?

Editorial team Published on

Recommended pre-surgery guidelines include fasting instructions, medication adjustments, and hygiene steps to ensure your safety. Always follow your specific surgical team's exact instructions.

Eating and Drinking (Fasting)

  • Stop eating and drinking usually after midnight, or specific hours before your arrival as directed by your American Society of Anesthesiologists guidelines.
  • Avoid swallowing water if you brush your teeth the morning of surgery.
  • Take allowed medications with only a tiny sip of water if instructed by your doctor.

Medications and Supplements

  • Stop blood thinners (like aspirin or NSAIDs) several days before surgery, as directed by your physician.
  • Discontinue herbal supplements and vitamins roughly 7 to 14 days prior to prevent bleeding or interactions.
  • Inform your care team about all prescription drugs, especially if you take insulin for diabetes or blood pressure medications.

Skin and Personal Care

  • Shower the night before and morning of your procedure, often using an antibacterial or antiseptic soap like Hibiclens if provided.
  • Do not shave the surgical site yourself with a razor, as tiny cuts can invite bacteria.
  • Skip lotions, makeup, perfumes, deodorant, and nail polish on the day of surgery.

Day of Surgery Logistics

  • Leave valuables and jewelry at home, and remove all body piercings.
  • Remove contact lenses, glasses, dentures, or hearing aids before the procedure, or bring cases to store them safely.
  • Arrange for an adult driver to take you home, since sedation prevents you from driving safely.
  • Bring your photo ID, insurance cards, and a list of current medications.

What not to do 2 weeks before surgery?

Avoid taking blood-thinning medications, NSAIDs, and certain supplements two weeks before surgery to reduce the risk of excessive bleeding and anesthesia complications.

Medications and Supplements to Stop

  • NSAIDs and pain relievers: Stop taking aspirin, ibuprofen (Advil, Motrin), and naproxen (Aleve).
  • Herbal supplements and vitamins: Avoid high-dose Vitamin E, fish oil, garlic, ginkgo biloba, ginseng, and St. John's wort.
  • Diet pills: Discontinue weight-loss or diet medications that can impact heart rate and blood pressure.
  • Prescribed blood thinners: Contact your prescribing doctor before stopping medications like warfarin or Plavix.

Habits and Lifestyle Changes

  • Smoking and tobacco: Stop smoking completely, as nicotine restricts blood flow, delays wound healing, and increases infection risks.
  • Alcohol: Avoid heavy alcohol use, which can interact poorly with anesthesia and impair recovery.
  • New illnesses or symptoms: Do not ignore new fevers, coughs, or signs of infection; report them to your surgical team immediately.

Do I really need to shower the night before and morning of surgery?

Yes, you really need to shower both the night before and the morning of your surgery to lower your risk of a serious wound infection.

Why It Matters

  • Reduces bacteria: Your skin naturally carries germs. Washing twice removes as many bacteria as possible so they do not enter your body during the operation.
  • Stops growth: Bacteria quickly multiply on the skin. Showering the night before and again right before you leave for the hospital keeps the germ count at its lowest point.

How to Do It Right

  • Use special soap: Your surgical team may ask you to use an antiseptic soap called CHG (chlorhexidine gluconate) or a standard antibacterial soap.
  • Follow the steps: Wash your body gently from the neck down for about five minutes, paying close attention to your surgical area. Do not get the special soap in your eyes, ears, mouth, or face unless directed.
  • Skip the extras: After drying off with a clean towel, do not apply any lotions, oils, creams, deodorants, perfumes, or makeup.
  • Put on clean clothes: Wear freshly washed clothes and sleep on clean bed sheets after your night-before shower.

What is the best meal to eat the night before surgery?

The best meal to eat the night before surgery is a light, simple, and low-fat dish that is easy for your stomach to digest.

Recommended Meal Ideas

  • Grilled or baked chicken or fish with a side of plain white or brown rice and cooked vegetables.
  • Eggs on toast with a side of fruit or oatmeal.
  • A baked potato with a small portion of lean protein and steamed broccoli.

What to Look For

  • Lean protein: Helps support tissue repair and recovery (e.g., chicken, turkey, fish, or eggs).
  • Complex carbohydrates: Provides steady energy (e.g., brown rice, quinoa, or whole-grain toast).
  • Mellow vegetables: Choose cooked or steamed options like carrots or green beans that will not cause gas or bloating.

What to Avoid

  • Greedy or fatty foods: Fried foods, heavy sauces, and red meat take much longer to digest and can cause indigestion.
  • Spicy or heavily processed foods: These can upset your gastrointestinal tract right before a procedure.
  • Gassy vegetables: Skip raw cruciferous vegetables like heavy broccoli, cabbage, or large amounts of beans.

Important Fasting Rules

Always follow the specific instructions given by your surgical care team or anesthesiologist. In general, you must stop eating solid foods at least 8 hours before surgery (often after midnight). Clear liquids may be allowed up to a few hours before you arrive, but your doctor's exact timeline overrides general advice.

What are standard pre-op tests?

Standard pre-op tests include blood work, heart checks, and imaging based on your health history and the type of surgery you are having.

There is no single list of tests for everyone. Doctors order them based on your age, medical conditions, and risk level.

Common Blood Tests

  • Complete Blood Count (CBC): Checks for anemia, low platelets, and infection.
  • Basic Metabolic Panel (BMP): Measures blood sugar (glucose), kidney function, and electrolytes like sodium and potassium.
  • Coagulation Studies: Tests how well your blood clots.
  • Pregnancy Test: Required for women of childbearing age for safety with anesthesia.

Diagnostic and Imaging Tests

  • Electrocardiogram (ECG/EKG): Checks heart rhythm and electrical activity, often used for older adults or those with heart risk factors.
  • Chest X-ray: Evaluates lungs and heart size, usually if you have a history of cardiopulmonary disease.
  • Urinalysis: Screens for urinary tract infections or kidney issues.

What's the worst day of the week to have surgery?

Friday (or the day before a long weekend) is generally considered the worst day of the week to have elective surgery due to a phenomenon known as the "weekend effect".

Why Fridays Carry Higher Risks

  • Staffing Shortages: Hospitals typically operate with reduced staff, fewer support personnel, and limited specialist availability over the weekend.
  • Less Experienced Coverage: Studies indicate that surgeons operating on Fridays or covering weekend shifts often have fewer years of experience than those working earlier in the week.
  • Delayed Response to Complications: The critical early recovery phase immediately follows the operation. If a complication arises during the weekend, access to diagnostic scans, specialized tests, and senior clinicians may be delayed.
  • Statistical Impact: Research published in major medical journals shows a roughly 5% higher risk of adverse outcomes—including complications, readmissions, or death—for surgeries done right before the weekend compared to a Monday procedure.

What This Means for Patients

  • Do Not Delay Urgent Care: Experts stress that these risks are relatively small and should not cause you to delay medically necessary or urgent surgery.
  • Talk to Your Doctor: If you are scheduled for a Friday procedure, ask your surgical team about their weekend monitoring protocols and post-discharge support.

Do they cover your privates during surgery?

Yes, medical staff cover your private parts during surgery using sterile sheets called drapes, except for the exact area where the operation takes place.

How Privacy is Maintained

  • Surgical Drapes: Large, sterile sheets cover most of your body. They have a small open window or slit only over the surgical site.
  • Blankets and Gowns: Staff use warm blankets to cover your upper and lower body before the operation begins.
  • Professional Standards: Operating room teams treat patients with strict clinical and professional respect. They view the body purely for medical safety.

When Exposure Happens

  • The Operation Area: If your surgery is on your abdomen, hips, or lower body, your private parts may need to be uncovered or prepped with antiseptic.
  • Drapes Remain: Even during lower-body procedures, sterile drapes surround the area, and staff keep non-surgical parts covered whenever possible.
  • You Are Asleep: For major procedures requiring exposure, you are already under general anesthesia and will not be awake or aware.

Do you have to sleep on clean sheets before surgery?

Yes, sleeping on clean sheets the night before surgery is a standard recommendation from many hospitals and surgical care teams.

Why Clean Sheets Matter

  • Reduces bacteria: Fresh linens lower the amount of dust, dirt, and skin cells on your bed that can touch your clean skin.
  • Lowers infection risk: Hospitals recommend this step along with special antiseptic showers to keep your skin free of germs before your procedure.
  • Helps recovery: Putting on clean sheets before you leave for the hospital also ensures a clean space to rest when you return home.

Best Practices the Night Before

  • Take a special shower: Wash with antibacterial or chlorhexidine soap as directed by your doctor.
  • Wear clean clothes: Put on freshly laundered pajamas after your shower.
  • Keep pets away: Do not let pets sleep in your bed after you shower and change your sheets.

Why is day 3 the hardest after surgery?

Day 3 is often the hardest after surgery because the body's inflammatory response peaks and residual hospital pain medications or nerve blocks fully wear off.

Why Day 3 Feels the Hardest

  • Peak Inflammation: Your body ramps up its natural healing and inflammatory response to repair surgical trauma, which increases swelling, tightness, and pressure around the tissue.
  • Worn-Off Medications: Long-acting regional nerve blocks, hospital-administered narcotics, and general anesthesia have completely left your system by the third day.
  • Catching Up on Pain: Patients often feel surprisingly good on Day 1, skip scheduled doses or try to reduce medication too early, and find it difficult to regain control once the pain spikes.
  • Overexertion: Feeling decent initially can lead people to do too much movement or light chores on Day 2, causing delayed soreness and increased pain by Day 3.

What are the top 3 riskiest surgeries?

While medical advancements have made surgical procedures safer than ever, certain operations carry higher inherent stakes due to their complexity, the critical organs involved, and the potential for severe blood loss.

Based on medical data and surgical complication rates, the top 3 riskiest surgeries frequently identified by experts include:

1. Thoracic Aortic Dissection Repair

This is an open surgery performed to fix a tear in the aorta, the body’s main artery that carries blood away from the heart.

  • Why it's high-risk: Because it is often performed as an emergency, surgeons must race against time to prevent the artery from rupturing completely. It carries a high risk of catastrophic bleeding, organ failure, or stroke. Estimated mortality rates for this emergency procedure can range from 20% to 30%.

2. Pancreaticoduodenectomy (The Whipple Procedure)

Commonly used to treat pancreatic cancer, this highly complex abdominal surgery involves removing the head of the pancreas, a portion of the small intestine, the gallbladder, and part of the bile duct.

  • Why it's high-risk: The surgeon must carefully reconnect the remaining digestive organs so they can function properly. The procedure is exceptionally delicate, and complications like severe digestive fluid leaks, internal bleeding, and post-operative infections occur in a significant percentage of patients.

3. Craniectomy

Unlike a craniotomy (where the skull is opened and immediately closed), a craniectomy involves removing a portion of the skull and leaving it off temporarily to allow a swelling brain room to expand.

  • Why it's high-risk: It is typically performed under dire circumstances, such as traumatic brain injuries, major strokes, or severe hemorrhages. Leaving the brain without the protection of the skull exposes it to a high risk of further brain damage, severe infection, and long-term neurological complications.

Key Factors That Drive Surgical Risk

Medical professionals typically categorize a surgery as "high risk" if the statistical chance of major complications or mortality exceeds 1%. A procedure's overall danger level is rarely determined by the surgery alone, but rather a combination of:

  • Urgency: Emergency surgeries carry significantly higher mortality rates than elective, planned procedures.
  • Patient Health: Underlying chronic illnesses, advanced age, and frail cardiovascular systems drastically increase overall risk.
  • Vital Organ Involvement: Any surgery interacting directly with the brain, heart, or central nervous system carries a baseline elevation in risk due to the potential for permanent nerve damage or loss of oxygen.
