Practice Guidelines for Nutrition in Critically Ill Patients: A Relook for Indian Scenario

Review of background correlations and intensities of various existing guidelines, meta-analysis, randomized controlled trials (RCT), comparative trials, and evaluation papers

Systematic scoring of the above review evidence (level 1 to level 6, highest level of the first level and lowest level of the sixth level)

Level 1 is "Existing Guidelines", Level 2 is "RCT / Meta Analysis", Level 3 is "Control Experiment / Research", Level 4 is "Uncontrolled Test / Research", Level 5 is "Commentary Articles" Level 6 "Expert ideas / opinions of the Advisory Committee".

Next, classify the practice guide as Class A, Class B, or Class C based on the strength of the supporting evidence.

Evidence of Level A / Level II supports the practice guide of Level A and shows "strongly recommended".

Various physiological metabolic changes occur in seriously ill patients. These changes may increase the risk of malnutrition. [1] Decreasing total calories and protein intake complicates the deterioration of the clinical condition. Increased sepsis, increased inflammatory biomarker, and metabolic imbalance can lead to multiple organ dysfunction, shock and death. A comprehensive assessment of critically ill patients helps identify nutritional support strategies and further improve patient outcomes.

Nutritional support will be important to meet the macro and micro nutritional needs of such patients. The route of administration of feed (intestinal or parenteral) should be determined based on the evaluation of hemodynamics and gastrointestinal function. [2] This will prevent risks associated with erroneous feeding techniques. Early enteral nutrition (EEN) in critically ill patients has been found to be associated with many benefits while reducing the risk of complications [3]. The patient's outcome in the intensive care unit (ICU) will be affected by the appropriate episode of onset, the amount and type of nutrients. Beginning feeding within 24 to 48 hours of a serious illness is defined as an early nutrition intervention. [4] EN start can be achieved by oral route or tube feeding based on nutritional validity goals

Certain drugs directly or indirectly affect nutrients and electrolyte concentrations. Interaction between drugs and nutrients must be evaluated daily. Interdisciplinary teams, including nutritionists, should evaluate the interactions of drugs and nutrients that are routinely considered. [Five]

Evaluate the nutritional status of the patient, and in particular if it is necessary to start nutritional supplementation within 48 hours of admission (especially severe patients). A recent review by Casaer suggests that it is reasonable to supply micronutrients starting with some stomach feeding in the acute phase of serious illness (10). The next step is to determine the type of feed (7) according to the individual's instructions, the period, and the requirements. Table 2 shows the general types of feeds and uses.

In clinical settings, nutrition is critical for all patients, but for seriously ill patients this is a big problem. Nutrition is very important as there is evidence that acute patients have many physiological changes. "Energy sources are not nutrients, but they are equally important to health" (Benyon, 1998). The acute patient score of Step 3 of the tool is 2 points, which is relatively high due to lack or lack of intake of nutrients. When patients are in critical condition, the energy level is very low, as they are usually very limited to physical activity or not at all. According to Bapen (2003), weight loss of acute patients may reach more than 10% in 3 to 6 months.
