Medical electrolyte composition and preparation method thereof
Technical Field
The invention relates to a medical electrolyte composition and a preparation method thereof, belonging to the technical field of medical nutritional food and preparation methods thereof.
Background
Diet prohibition before selective operation is used for reducing the capacity and acidity of gastric contents and preventing vomiting and aspiration during anesthesia. At present, textbooks in China still use the traditional view: adult patients with selective surgery are fasted for 8-12 hours before operation and forbidden to drink for 4 hours. However, in recent years, it has been discovered that the actual fasting time of more than 10h and the drinking prohibition time of more than 6h before the operation can cause the adverse reactions of the patients, such as thirst, hunger, anxiety, dehydration, hypoglycemia and the like. The blood sugar of the organism is reduced under the state of food and drink prohibition, which leads to the reduction of insulin secretion, the increase of glucagon, growth hormone and catecholamine secretion, the acceleration of glycogen decomposition and the increase of glycogenesis. Long-term drinking prohibition promotes muscle protein mobilization, hepatic glucose isomerization and increased glucose production to supplement blood sugar. The decomposition of fat in the body is increased, and becomes the main energy source of the body. Therefore, in the early period of fasting, if the glucose can be supplemented in time, the xenogenesis of the protein can be obviously reduced, and the protein is saved; moreover, the supplement of glucose can prevent ketosis caused by fat decomposition and reduce the incidence of acidosis. Surgery is a trauma to the body and can lead to post-operative insulin resistance. It is an important metabolic factor affecting postoperative recovery, increases the productivity and fatality rate of postoperative complications such as bacteremia and infection, and has become an important influencing factor for determining the length of postoperative hospitalization.
The ideal bowel preparation is: the colon is completely empty, antibiotics are not needed, the number of bacteria in the intestinal cavity is reduced, electrolyte balance is maintained, the pain of a patient is small, and the nursing time is shortened. The good preoperative preparation can clean the intestinal tract, is convenient for surgical operation, reduces the quantity of intestinal bacteria, promotes wound healing, and reduces the occurrence rate of pollution and postoperative infection. In order to enable a patient to be in a good functional state before an operation, on the basis of shortening the time of food and drink prohibition, certain clinical studies are to orally take glucose and electrolyte (namely 50g of glucose and 5g of sodium chloride added with 500mL of water) or carbohydrate beverage (12.5g of carbohydrate per 100mL) or carbohydrate beverage before an operation for the patient, after the patient drinks the electrolyte-containing solution in a short time, intestinal tract water can be absorbed additionally due to osmotic pressure in the intestinal tract, watery stool is discharged downwards, the whole colon or even the tail end of the ileum can be flushed cleanly, the effect is fast, the irritation to the intestinal tract is small, and a good effect is obtained.
However, this method requires a relatively large amount of electrolyte-sodium (5g/500mL) and contains a relatively high amount of glucose, and is not suitable for patients who need to control the intake of sodium and glucose, such as diabetic patients, and in addition, the preoperative patients are bedridden for a relatively long time, have little walking, have slow intestinal motility, and are excreted by osmotic pressure generated by the electrolyte, and the efficiency is relatively slow. Moreover, the carbohydrate beverage provides energy for patients through monosaccharide (glucose or fructose) and polysaccharide (maltodextrin), the monosaccharide and the single polysaccharide (maltodextrin) can be quickly absorbed and utilized by human bodies, the energy release is quick, and the satiety duration is short.
In the literature "comparison of the hyperglycemic effect of different carbohydrates" (release of the journal of preventive medicine, volume 35, 9, 2017), the test results show that: the maltodextrin has obvious and mild blood sugar increasing effect, the fructose has mild blood sugar increasing effect, and the oligosaccharide and the like have no obvious blood sugar increasing effect on the body in a short time. The present invention is based on the finding that a medical electrolyte composition is provided which is capable of smoothing blood glucose, reducing hunger sensation and helping defecation and cleaning the intestine of a patient before an operation.
In the document "comparison of prebiotic functions and effects of different functional oligosaccharides" (china journal of food additives, 2009), the results of comparative experiments show that: among the proliferation effects of fructo-oligosaccharide, galacto-oligosaccharide and isomalto-oligosaccharide on beneficial bacteria, galacto-oligosaccharide is the only prebiotic which can be utilized by 9 beneficial bacteria (bifidobacteria, namely bifidobacterium infantis, bifidobacterium breve, bifidobacterium adolescentis, bifidobacterium bifidum and bifidobacterium longum, lactobacillus, namely lactobacillus acidophilus, lactobacillus casei, lactobacillus fermentum and lactobacillus salivarius) in the human intestines, and is more beneficial to the proliferation of the beneficial bacteria in the intestines, thereby providing guarantee for the immunity enhancement of postoperative patients.
The document "A comparative in vitro evaluation of the transfer property of the biological oligonucleotides" (Journal of Applied Microbiology 2001) describes comparative experiments: in the capability (time and acid yield) of producing organic acids (lactic acid, acetic acid, propionic acid and butyric acid) by fructo-oligosaccharide, galacto-oligosaccharide, xylo-oligosaccharide and isomalto-oligosaccharide, the acid yield of galacto-oligosaccharide is higher in a short time (5h) than that of other oligosaccharides, a higher content level can be maintained in a longer time (24h), and the higher intestinal acidity can prevent colonization of harmful bacteria in the intestinal tract and is more beneficial to discharge the harmful bacteria out of the body. Meanwhile, the gas production is compared: the gas yield of the galacto-oligosaccharides is relatively minimum in the galacto-oligosaccharides, the inulin, the xylo-oligosaccharides and the soybean oligosaccharides, so that the patients are less disturbed by bad feelings such as intestinal flatulence, rugitus and the like caused by the proliferation of neutral bacteria.
