Importance of Pre-Anesthesia Guidelines
Before undergoing any medical procedure that involves anesthesia, patients receive specific instructions from their healthcare providers. These guidelines are in place to help prepare the body for anesthesia and surgery. Following these instructions is an important part of the overall care plan designed by your medical team.
Fasting Before Anesthesia
One of the most common and important instructions given to patients is to refrain from eating or drinking before surgery. The purpose of this fasting period is to reduce the volume of stomach contents before the administration of anesthesia.
General Fasting Timeframes:
- Solid Food: Typically, patients are instructed not to eat solid food for 6 to 8 hours before a procedure.
- Clear Liquids: Clear liquids, such as water, black coffee, or apple juice, may be allowed up to 2 hours before the scheduled time.
The specific fasting instructions may vary based on the type of procedure, your medical history, and the specific guidance from your anesthesiologist. Always follow the instructions provided by your healthcare team.
Medications and Supplements
Managing medications and supplements before anesthesia is another critical step. Many substances can interact with anesthetic agents or affect the body's response to surgery, such as blood clotting. A comprehensive review of all medications and supplements with your doctor is essential.
Commonly Restricted Substances:
- Blood Thinners: Medications like aspirin, warfarin, clopidogrel, and newer oral anticoagulants are often stopped several days before surgery to reduce the risk of excessive bleeding. The exact timing will be determined by your doctor.
- NSAIDs: Nonsteroidal anti-inflammatory drugs like ibuprofen and naproxen can also affect blood clotting and are frequently stopped a week before surgery.
- Certain Herbal Supplements: Many herbal products can have effects that may interfere with anesthesia or increase bleeding risk. It is generally recommended to stop these several weeks before surgery.
Your doctor will provide a list of medications to stop and those to continue. It is crucial to inform your medical team about everything you are taking.
Lifestyle Considerations
Certain lifestyle habits can also impact your readiness for anesthesia. Open communication with your anesthesiologist about these habits is important for them to plan your care effectively.
- Smoking: Smoking can affect lung function and healing. Patients are often advised to stop smoking for a period before surgery, ideally several weeks, but at least 24 hours is usually required.
- Alcohol: Alcohol consumption can affect hydration, liver function, and interactions with medications. Avoiding alcohol for at least 24 hours before surgery is commonly recommended, and longer periods may be advised.
- Recreational Substances: Use of recreational drugs, including marijuana, should be disclosed to your medical team as these can affect your response to anesthesia.
Day of Surgery Guidelines
On the day of your procedure, there are additional instructions to follow:
- Avoid Cosmetics: Do not wear makeup, lotions, or deodorant on the day of surgery.
- Remove Jewelry: All jewelry, including piercings, should be removed.
- No Contact Lenses: Remove contact lenses before arriving at the hospital.
- No Gum or Mints: Avoid chewing gum or mints before surgery.
- Remove Nail Polish: Nail polish may need to be removed as well.

Conclusion
Preparing for a medical procedure involving anesthesia requires careful attention to the instructions provided by your healthcare team. Understanding what you shouldn't do before anesthesia, such as fasting, managing medications and supplements, and making temporary changes to lifestyle habits, is an important part of the process. By following these guidelines, you cooperate with your medical team to help facilitate a smooth and safe experience. Always communicate openly with your doctors and anesthesiologist about any questions or concerns you may have regarding your pre-operative instructions.
