Healthy people who are scheduled to have minor surgery can drink a glass of water four hours before the procedure. Of course, if your doctor has instructed you to fast for 12 hours, you should follow his or her recommendations. It clearly minimizes the possibility of difficulties.
People who are more sensitive to alcohol (1-2 drinks per day) should not drink anything by mouth for at least two hours prior to surgery.
Hydration is extremely important before, during and after any type of surgery. In fact, inadequate preoperative hydration is associated with increased post-op morbidity such as pneumonia, deep vein thrombosis and failure-to-resolve postsurgical ileus. Post-op dehydration is also linked to increased risk of developing kidney stones, heart disease and diabetes later in life.
It is recommended that patients drink plenty of fluids prior to surgery to keep themselves well hydrated. You should start drinking about four hours before your operation to allow time for your stomach to empty it will help with pain relief and prevent dehydration. After surgery, patients are advised to drink enough to stay hydrated. This may be in the form of clear liquids such as water, tea or coffee or soft foods such as soup or toast. Do not eat anything solid for at least six hours after surgery.
Fasting is normally required starting six hours before surgery. You may be allowed to drink clear fluids until a few hours before the procedure. During your fasting period, your doctor may advise you to take some of your normal prescriptions with a little sip of water. Consult your doctor about your drugs. Some medications can be harmful when taken with alcohol or other medicines.
It's important to discuss any allergies with your anesthesiologist before putting you under. Allergies to medications used in anesthesia include soy products, milk proteins, corn syrup, citrus fruits, vinegar, and red wine. If you have such an allergy, talk to your doctor about alternatives before you go into surgery.
You will be asked to sign a consent form for the anesthesia you will receive. This form tells us that you understand what will happen during your anesthesia and agree to this treatment if you need it.
Anesthesia masks the feeling of pain by either injecting or pumping chemicals into the blood stream or both. It can also affect the senses of hearing and sight. A nurse or other hospital staff member will explain the process used in your case and answer any questions you may have. You will probably be given several pills to take before your surgery which contain mild analgesics to make you feel better after the anesthesia. These pills are called post-operative analgesics or PAOs for short.
Most patients only need one type of anesthesia to get through their surgery.
Patients undergoing sedation must adhere to the current fasting recommendations for general anaesthesia. You should not eat or drink anything for 6 hours before your treatment, although you may drink water up to 2 hours before. Your procedure will be canceled if you eat or drink after these times.
As long as you follow these instructions, there is no need to worry about drinking water before you are given a sedative.
Fasting 12 hours before surgery is a standard norm before any type of operation. This is done as a preventative step. Excess water in your system during surgery might result in pulmonary aspiration. This could be fatal.
Asking patients to refrain from drinking anything for 12 hours before surgery begins allows the surgeon time to prepare the patient's body for anesthesia by reducing fluid in the stomach and intestines. The patient's metabolism is slowed down while under general anesthesia, so it is important that they do not eat or drink anything after midnight the night before their operation. This is especially important for obese patients who need less food than normal weight people to stay hydrated during sleep.
It is recommended that you stop eating two days before your operation. This will reduce the amount of liquid in your stomach and make it easier for surgeons to perform procedures without being distracted by any content there. Drinking plenty of water is important too - at least eight 8-ounce glasses per day.
After surgery, it is important to drink enough fluids to keep yourself hydrated. This is particularly important if you are unable to eat properly due to pain. Some patients may also receive nutrition via a feeding tube after major operations.
