Description
Technical field
The invention belongs to medical instruments field, specifically a kind of intelligence of the enteral nutrition closed loop based on small intestinal enteric cavity pressure infusion system.
Background technology
The homergy of human body and good nutritional status are the important guarantees safeguarding vital movement.Any metabolism disorder or malnutrition all can affect the function of tissue, organ, worsen further and can make organ failure.The nutritional status of body and morbidity and mortality rate are closely-related.All can there is malnutrition in various degree in many critical illness, corrected if do not adopted vigorous measures, and is often difficult to give treatment to successfully.On basis organism metabolism being had to enough understanding, the foundation of effective import pathway, and various production in succession and the application meeting the little nutritional preparation of physiology, side reaction, make professional Medical Degree treatment in modern age obtain very outstanding effect, save the life of many critical patients.
Total parenteral nutrition (total parenteral nutrition, TPN) is the nutrition supporting therapy developed rapidly in the later stage sixties 20th century, once in wide clinical application.But along with progressively going deep into of studying nutritional support theory and practice, people recognize that parenteral nutrition mainly exists three class complication, comprise: (1) technical complication: as the damage of pneumothorax, blood vessel injury, nerve or thoracic duct, the most serious has air embolism, once it is serious that consequence occurs, even cause death; (2) metabolic complication: the electrolyte disturbance, trace element deficiency, the essential amino acids shortage that cause as supplementary deficiency, the hypoglycemia that carbohydrate metabolism disturbance causes or hyperglycemia, liver function injury, also can cause gallbladder inner bag mud and calculus, the rising of cholestasis regulating liver-QI zymogram, intestinal barrier function to go down in addition; (3) infection complication: as conduit sepsis.
Enteral nutrition (enteral nutrition, EN) is not only more reduced expenses than TPN, and more meets physiological status, is considered to the important measures recovering intestinal blood flow, improve intestinal function.Along with the development of enteral nutrition, in nutritional support process, metabolic complication greatly reduces.But in the implementation process of enteral nutrition, patient often there will be the intestinal tract complications such as abdominal distention, stomachache, diarrhoea.The generation of intestinal tract complication and the toleration of small intestinal to enteral nutrition closely related.Therefore further investigation and improve patient to the toleration of enteral nutrition to guidance clinical effectively implement enteral nutrition have important value.
Small intestinal is not only subject to the impact of enteral nutrition scheme, Small Intestine and paathogenic factor on the toleration of enteral nutrition, also by the impact of the factors such as nutrient composition, osmotic pressure, input time, speed, temperature, concentration and nutritive canal implantation mode, and the impact of these factors is often embodied a concentrated reflection of in the change of intestinal cavity pressure.
At present, domestic and international present Research and development trend as follows:
Nutritional support is considered to one of greatest achievement of 20th century medical circle, but is difficult to carry out without effective approach and preparation with cause in the 1950's as the enteral nutrition of nutritional support important component part.Nineteen fifty-seven be spaceman exploitation enteral nutrition preparation because normal growth, the reproduction of rat can be maintained, be applied to human body in nineteen sixty-five, enteral nutrition is progressively carried out clinical since then.
To 20th century the mid-80 along with being familiar with again intestinal function, especially the establishment of the new theory such as " intestinal mucosal barrier ", " in intestinal bacterial translocation " and " intestinal is a center organ of stress ", new ideas, the application and research of EN support is increasing.Enteral nutrition contributes to the integrity maintaining intestinal mucosa cells structure and fuction, support intestinal mucosal barrier, reduce the generation of enterogenic infection, and be considered to the important method improving cancer patient nutriture and quality of life, so the ratio of external clinical practice enteral nutrition is increased to 80% by original 20%, domesticly also to increase sharply.
But in concrete clinical implementation process, enteral nutrition not can be easily accepted by the patient.Too early, implement enteral nutrition too quickly and occur severe complication sometimes, such as bowel necrosis.At present enteral nutrition toleration is evaluated to the clinical manifestation of Main Basis patient, as gastrointestinal reactions such as abdominal distention, stomachache and diarrhoea, and lack the evaluation index of objectivity.
Because the intrinsic factor affecting little gut tolerance during enteral nutrition are intestinal motility and absorption function two aspects, therefore the comprehensive objective evaluation index of objective indicator as little gut tolerance of searching above-mentioned two aspects of concentrated expression can be imagined, thus reach requirement that is accurate, comprehensive, objective evaluation.Chinese scholars is once using the research method of the mensuration of enteric cavity pressure as intestinal movement function, current research display: for the small intestinal accepting enteral nutrition, the change of enteric cavity pressure is the synthesis result of intestinal motility and absorption function change, is also disconnected and occur the pathogenesis basis of the intestinal tract complications such as abdominal distention, stomachache and diarrhoea.Therefore, small intestinal intestinal cavity pressure mensuration can concentrated expression intestinal motility and absorption function change overall condition.
Generally, when jejunal nutrition, any method of intubation is all a certain position being fixed on small intestinal, and every section of intestinal motility all shrinks-relaxes and hockets, namely each position enteral pressure is constantly change, so desirable intestinal nutrient solution input method automatically can speed input, input of slowing down when enteral voltage rise height when enteral pressure lowers, even minibreak, makes the change of enteral pressure play the effect intelligently adjusting infusion.This infusion methods has also taken into account the daily cycle property change of gastrointestinal physiological function, farthest can improve the toleration of small intestinal to enteral nutrition.
