Modern surgical guidelines now often permit patients to drink clear liquids, including certain electrolyte beverages, up to two hours before a procedure, a significant departure from older, stricter fasting protocols. This practice is based on extensive research demonstrating improved patient comfort and recovery.

According to guidelines from the American Society of Anesthesiologists (ASA), clear liquids like black coffee are generally permitted up to two hours before a procedure requiring anesthesia. The rule of thumb for whether black coffee is permitted when NPO depends on factors such as the type of liquid and the timing relative to the procedure.

According to the American Society of Anesthesiologists (ASA), black coffee is explicitly included in their definition of clear liquids permitted before a medical procedure. The key, however, is that for coffee to be considered a clear fluid before surgery, it must be completely plain—without any milk, cream, or sugar.

According to a systematic review from the *Cureus* journal, perioperative probiotic or synbiotic interventions have been associated with a significant reduction in post-operative infectious complications, highlighting their potential role in surgical outcomes.

According to the American Society of Anesthesiologists, many patients fail to disclose their use of herbal supplements, a practice that can increase the risk of surgical complications. Understanding the specific risks associated with different forms of cranberry is crucial for patient safety.

For bariatric surgery, many healthcare teams advise a very low-calorie, low-carbohydrate diet for at least two weeks beforehand to shrink the liver, making the procedure safer. However, the exact duration of a low starch or low carb diet before surgery can vary significantly depending on the specific procedure and individual health factors.

Studies show that abnormal preoperative potassium levels are associated with higher risks of adverse cardiovascular events and mortality. Checking a patient's potassium levels before surgery is a standard, essential protocol performed to safeguard against dangerous complications under anesthesia. This simple blood test can reveal hidden risks that may affect heart rhythm, muscle function, and overall surgical outcomes.

Studies show that prolonged overnight fasting before surgery, a traditional practice, causes metabolic stress that can impede recovery. The modern approach uses a pre-surgery carbohydrate drink as a key component of Enhanced Recovery After Surgery (ERAS) protocols, designed to prepare the body and mitigate the negative side effects of fasting.

According to Memorial Sloan Kettering Cancer Center, patients typically need to follow a liquid diet the day before surgery to ensure an empty stomach. A liquid diet before laparoscopic surgery is a critical step in preparing your body for the procedure, minimizing complications, and promoting a smooth recovery.

According to modern Enhanced Recovery After Surgery (ERAS) protocols, consuming clear, carbohydrate-rich fluids like Gatorade is often not only permitted but encouraged up to two hours before a procedure. This contrasts sharply with the traditional 'nothing by mouth' (NPO) fasting from midnight, a practice that is increasingly being replaced by evidence-based guidelines to improve patient outcomes.
