Summary
Preoperative fasting can be detrimental to patient recovery. Allowing clear liquids before surgery improves outcomes and patient comfort, reducing hospital stays.
Area of Science:
- Anesthesiology
- Metabolic Medicine
- Surgical Patient Care
Context:
- Preoperative fasting, a long-standing practice to prevent aspiration pneumonia, has metabolic disadvantages.
- Surgery induces hypercatabolism and hyperglycemia due to insulin resistance.
- Current practices are shifting away from prolonged fasting for specific elective procedures.
Purpose:
- To evaluate the safety and benefits of clear fluid intake before elective surgery.
- To analyze the impact on postoperative insulin resistance.
- To assess effects on patient comfort, surgical outcomes, and length of hospital stay.
Summary:
- This paper reviews the established use of clear liquids in elective surgery, moving beyond traditional fasting protocols.
- It examines how preoperative clear fluid intake influences metabolic responses, specifically postoperative insulin resistance.
- The study also considers patient comfort, overall surgical outcomes, and hospital length of stay.
Impact:
- Supports evidence-based guidelines for enhanced perioperative patient management.
- Highlights potential improvements in patient recovery and resource utilization.
- Contributes to a paradigm shift in preoperative care, prioritizing metabolic health and patient well-being.

Enteral Nutrition II: Nasointestinal and Gastrostomy Feeding
Enteral nutrition encompasses various methods of delivering nutrition directly to the gastrointestinal (GI) tract, bypassing traditional oral intake. It is particularly beneficial for patients who cannot eat by mouth but have a functioning digestive system. Key methods include nasointestinal feeding, gastrostomy, and jejunostomy, each suited to different clinical scenarios based on the patient's needs and condition.

Metabolic States of the Body: Fasting and Starvation
During the initial hours of fasting, the body uses up its glycogen stores as an energy source. Once these glycogen reserves are depleted, the body begins breaking down stored triglycerides and structural proteins. During this stage, glycerol becomes a key substrate for gluconeogenesis, while free fatty acids undergo beta-oxidation to provide energy for tissues, such as skeletal muscle. In the fasting state, the body spares protein breakdown as much as possible to conserve muscle and structural...
Metabolic States of the Body: The Postabsorptive State
The postabsorptive state usually starts about four hours after a meal and lasts until the next meal is eaten. During this time, the digestive system stops absorbing nutrients, and the body uses stored energy reserves to maintain stable blood glucose levels.
Initially, glycogen stored in the liver is broken down to release glucose into the bloodstream, while glycogen in the muscles is broken down to supply glucose for energy directly within the muscle cells. As glycogen stores diminish,...

Enteral Nutrition I: Orogastric and Nasogastric Feeding
Enteral nutrition delivers nutrients directly to the stomach or small intestine through a tube. This method is appropriate for patients who cannot eat but still have a functioning digestive system. It is also beneficial for individuals with swallowing difficulties, anorexia, malabsorption, or those who have undergone gastrointestinal (GI) surgery.
Orogastric (OG) and nasogastric (NG) feeding are two standard methods used for enteral nutrition. Enteral nutrition is often preferred over...

Kidney Transplant II: Surgical Procedure
Preoperative ManagementThe primary goals of preoperative management in kidney transplantation are to optimize the patient’s metabolic state and prepare them for surgery through diet adjustments, necessary dialysis, and tailored medical treatment. This phase also involves comprehensive infection screening and patient education about the surgical procedure and postoperative care to improve outcomes and adherence.Medical ManagementA comprehensive evaluation is required for both the living donor...
Cardiomyopathy VII: Pre and Post Operative Nursing Management
Patients with hypertrophic cardiomyopathy (HCM) and left ventricular outflow tract (LVOT) obstruction who remain symptomatic despite optimal medical therapy may undergo a septal myectomy (Morrow procedure). This procedure involves excising a portion of the hypertrophied septum below the aortic valve using a heart-lung machine to improve blood flow through the LVOT. Effective preoperative and postoperative nursing management ensures successful patient outcomes, minimizes complications, and...
