Comparative Study Of Use Of Mechanical Ventilation And Enteral Nutritional Support In ICU Patients

background: In terms of critically ill patients, nutrition support plays an important role: malnutrition will result in ineffective immune response, poor wound healing, increased postoperative complications and hospital time. In the management and use of mechanical ventilation in COPD patients, nutritional status, nutrition, supply and respiratory function influence each other[1]. Nutritional support in critically ill patients is often unsatisfactory, more common in developing countries[2].While malnutrition increases the morbidity and mortality, especially for patients on the ICU[6]. Nutritional support, including parenteral nutrition and enteral nutrition. Enteral nutrition infusion method intermittent syringe infusion, continuous gravity drip infusion continued input, nutrition pump infusion, nutrition, intermittent infusion pumps, etc. Continuous enteral feeding at home and abroad and intermittent nasal feeding of different reports, there is controversy.Objective: This article aims to retrospectively analyze 60 cases of different enteral nutrition in patients with mechanical ventilation tube feeding method (continuous infusion of enteral feeding pump with intermittent nasogastric feeding) in the nasal feeding process complications, nutritional parameters, blood biochemistry, ventilation time, the success rate of weaning, whether the comparison of differences provide the basis for clinical care.Methods: The study selected 60 patients with mechanical ventilation in ICU, age, gender, disease, disease severity was no difference in the conditions, divided into two groups, namely, gastrointestinal nutrition by continuous infusion pumps and nutrition after gastrointestinal Intermittent infusion.The subjects were randomly divided into two groups, one group continued to pump into the enteral feeding pump another group of intermittent nasogastric feeding was observed with or without reflux, abdominal distension, diarrhea, ventilation time, weaning success rate and serum albumin levels before , serum albumin concentration, serum total protein concentration, and data analysis, whether there is statistically significant.Results: The intermittent infusion group in the serum prealbumin concentration, abdominal distension, diarrhea, regurgitation of comparison are different, the difference was significant, indicating intermittent infusion in serum prealbumin, gastrointestinal tract better than that infusion. The two groups in serum albumin and serum total protein concentration comparison, the change is not, the difference was not statistically significant (P <0.05), which may be serum albumin, serum total protein half-life longer and the data selected is too short (a week before and after the change in nasal feeding).Conclusion:1. ICU mechanical ventilation in patients with enteral nutrition, the use of intermittent infusion to reduce gastrointestinal side effects better than continuous infusion.2. Mechanical ventilation were treated with EN should be noted that in the nutritional assessment of blood biochemistry, serum prealbumin relatively short half-life of about 2 days, it reflects a sensitive index of nutritional status.3. Mechanical ventilation in patients with nutritional support in gastrointestinal reaction occurs with nasal feeding methods, feeding solution temperature, concentration, position, drug, severity of the disease and so on.4. Intermittent nasogastric feeding pump to reduce ventilator-associated pneumonia, reduction of the average ventilation time, increase the success rate of weaning was superior to continuous infusion of enteral feeding.
