Oral Nutrition: Fill & Download for Free

Because unfortunately many people in the surgical business, especially docs, still are very set in their old ways, even though it has been proven unnecessary. And it's just an overnight (≈12 hours), not 24 hours fast.At present, if there is no obstruction either in the gastric outlet or in the bowels so fluids can pass quickly from the stomach, the morning about 2-3 hours before the surgery we will give them 400 ml of a clear carbohydrate rich drink, this will through the Sulcus Ventriculi - what the Germans call the Magenrinne (a small "runnel" located at the lesser curvature = curvatura minor of the stomach) - immediately pass into the small bowels so leaving no fluid to regurgitate and thus no risk of aspiration if the patient needs to be intubated (given a tube in the airway to help them breath). Having given the patient nutrients before the insult - the operation - will change their metabolism from the fasting state and make them recover in a shorter time.No solids after midnight though.From the Oct-Dec 2007 Revista Colombiana de AnestesiologíaPre-operative fasting vs. oral nutritionThe metabolic implications of prolonged starvation vs. shorter fasting times are also important18. Studies have indicated that the availability of carbohydrates and the metabolic setting of the fed state are important factors which improve postoperative recovery16. The main objective of preoperative carbohydrate treatment is to cause a change in metabolism that normally takes place when someone takes their breakfast. This will elicit an endogenous insulin release that turns off the overnight fasting state of the metabolism. A carbohydrate-rich (12.5%) clear beverage containing mainly polymers of carbohydrates to minimize the osmotic load and thus reduce the gastric emptying time has been tested 23. Both in healthy volunteers and in preoperative patients 400 ml passed the stomach within 90 min. Studies in more than 250 patients have shown that the median residual gastric volume is only approximately 20 ml16,18. A small fraction of the patients had gastric volumes above 120 ml, the highest being 200 ml. When the 400-ml dose was divided into 2 200 ml, the last intake 2 h before the gastroscopy, the highest volume Pre-operative fasting guidelines found was 120 ml, with the averages approximately 35 ml.Studies have found that this carbohydrate-rich pre-operative beverage both improves subjective well-being compared with a placebo (water) and may positively affect the post-operative recovery16,19. From a patient safety point of view, it is important to notice that intake of up to 400 ml of the beverage does not produce negative effects on the gastric content compared with a similar intake of water16,24. The effect of oral fluid intake on peri-operative urine output should also be included in future studies42.

ABSORPTION OF VITAMIN A THROUGH HUMAN SKIN (JAMA of Dermatology)Can You Absorb Nutrients Through Your Skin?Vitamins and minerals are minimally (if at all) absorbed through the skin. Researchers are working on a dermal patch that could be worn by people who wouldn’t have access to adequate oral nutrition - but we’re not there yet.

To my understanding,there is no tablet alternative to food.infact Tablets such as Multivitamins,Calcium,Iron or any others are only used as health supplements.Health supplements provide supplementation to the deficient Nutrients,Vitamins or minerals for a human Being.During Sickness,the choice of the type of food changes,from more solid to more liquid type. or to a easily digestible food variety.For people who are in a condition of not taking food orally,nutrition route is changed accordingly.Thus considering all situation,there is no alternative tablet for food,in fact these days choice of Food as Medicine is on the Rise:)
