INTRODUCTION
The aim of nutrition is to supply nutritional needs of the critically ill patients. The patients who are seriously ill are prone to malnutrition owing to nausea, vomiting, dysphagia, poor mentation and mechanical ventilation. Patients with the head injury, stroke, brain tumours, acute spinal cord injury, and neurologic and neuromuscular disorders are the typical group of patients admitted to Neuro-Intensive Care Units (ICUs). These patients often require non-enteral nutrition owing to dysphagia, poor neurological status and mechanical ventilation. These patients are at risk for malnutrition due to hypercatabolism owing to the disease process, reduced oral intake, visceral protein loss and wasting of muscles due to immobility. A good nutrition supplementation can improve immunity, morbidity and mortality and length of hospital stay.[1]
Over the past several years, there is increasing emphasis on early nutritional therapy to all critically ill patients.[2] [3] Early enteral feeding has been shown to reduce catabolism and reduce complications and hence can reduce the length of hospital stay and morbidity and mortality in critically ill neurological patients. The benefits of early enteral feeding are more when the therapy initiated within 48–72 h of neurological insult.[3] [4] However, many neuro physicians and surgeons hesitate to start early nutrition therapy in these patients. Even the patients with silent abdomen can tolerate low jejunal feeds when initiated as early as 36 h post-injury.[5] However, many questions remain unanswered in neurologically ill patients, due to lack of precise clinical trials.

EFFECT OF CRITICAL ILLNESS ON DIFFERENT ORGAN SYSTEMS IN THE BODY
Almost all organs are affected during critical illness. The severity of the organs affected depends on the severity of the disease. The hypercatabolism and subsequent inappropriate nutritional supplementation can rapidly worsen the functioning of different organ systems in the body [Table 1].

NUTRITIONAL SCREENING AND ASSESSMENT OF NUTRITIONAL STATUS
Nutritional screening is the identification of the patient who is at risk of malnutrition based on the available basic data. Many nutritional tools such as malnutrition universal screening tool, nutrition risk index, mini nutritional assessment and subjective global assessment. Any nutritional screening tool can be adopted based on the institution, the infrastructure and available resources. A detailed discussion on these tools is out of the purview of this article and can be found elsewhere in the literature.
At present, there is no universally accepted gold standard for nutritional assessment of TBI patients. For adequate nutritional assessment, assessment of both medical condition of the patient and nutritional status is important. The diagnosis of the illness, comorbidities (coronary artery disease, diabetes, hypertension, etc.,) and assessment of each organ function should be considered. The anthropometric measurements and blood chemistry are used for assessing the nutritional status. The anthropometric measurements such as weight, height and body mass index are difficult to measure most of the times as patients are critically ill. The estimated measurements can also be inaccurate, due to disturbed fluid balance. The biochemical measurements include calculation of nitrogen balance, albumin, haemoglobin, magnesium, phosphorous, transferrin and pre-albumin.
#
CALCULATION OF CALORIC REQUIREMENT
The traditionally used Harris-Benedict’s equation or weight-based formulas (25–30 kcal/kg/day) are used for calculation of basal energy expenditure (BEE). These static formulas may not accurately predict the amount of replacement required considering the dynamic nature of the disease and hypercatabolism in patients with TBI. Repeated measurements of indirect calorimetry can be used for accurately assessing the energy expenditure. An amount of 140% of BEE is advocated in patients with TBI with the protein replacements of 1–2 g/kg/day. Considering the hypercatabolism state in patients with TBI, proteins can constitute 20% of the energy of the total daily intake.
#
TYPES OF NUTRITIONAL SUPPORT: ENTERAL AND PARENTERAL NUTRITION
There are essentially two types of dietary methods available: Enteral and parenteral nutrition. Enteral feeding is considered as the first choice, where a functioning gastrointestinal (GI) tract is a prerequisite. It has been found to reduce GI bacterial translocation and improves the mucosal integrity and enzymatic activity.[8] The main contraindications to enteral feeding include complete mechanical bowel obstruction, high draining enterocutaneous fistula (>500 ml) and intolerance to enteral feeding. The parenteral route of nutrition is employed, when there is a failure of enteral feeding or enteral feeding alone is not sufficient to meet all nutritional demands. [Table 2] compares the advantages and disadvantages of both types of nutrition.
#
TIMING OF NUTRITION: EARLY VERSUS DELAYED NUTRITION
The current trend is to start early nutritional replacement to all critically ill patients. Brain trauma Foundation guidelines recommend attaining full caloric requirement by 7 days.[9] For this, the nutrient replacement needs to be started within 72 h and gradually increased to achieve the complete caloric requirement. Studies in the past have tried to compare the early versus delayed nutritional replacement and outcomes in patients with TBI [Table 3] [4] [10] [11] [12] [13] [14] [15] [16] [17] One of the prerequisites for the enteral feeding is the functioning bowel (presence of bowel sounds). In two of these studies, enteral feeding was started even in the absence of bowel sounds and the patients tolerated the enteral feeding well.[12] [13] One of the studies demonstrated reduced infective and overall complications with early jejunal/gastric feeding.[13] This study also demonstrated that the patients who were fed early had a higher percentage of energy and nitrogen requirement by the end of 1 week.[13] A Cochrane meta-analysis[18] which included five studies[4] [10] [11] [12] [13] [14] concluded that there is a trend towards improved outcome and reduced complications with early enteral feeding.

As a part of New York State quality improvement programme, Brain trauma foundation collects data of 22 trauma centres in New York State.[14] The analysis of data collected from 2000 to 2006 revealed that there was 2–4-fold increased the risk of death in patients who were not fed within 5–7 days. Every 10 kcal/kg decrease in caloric intake during the first 5 days was associated with 30–40% increase in mortality rates. Similarly, the other two trials published recently concluded that early nutrition is associated with better outcomes.[15] [16] Chourdakis et al.[17] studied the effect of early versus delayed enteral feeding on endocrine functions of the patients with TBI. The hormonal levels of thyroid stimulating hormone, free T4 and free T3 were reduced in patients with delayed enteral feeding. A recent meta-analysis of available studies on nutritional supplementation in patients with TBI included 4 randomised controlled trials[4] [10] [11] [17] and three non-randomised prospective observational trials.[14] [15] [16] The pooled data indicated early nutrition is associated with significant reduction in mortality as compared to delayed initiation of nutrition.[19] Furthermore, analysis of 4 trials[10] [11] [15] [16] revealed the risk of poor outcome is significantly decreased with early nutrition. In summary, early feeding is associated with positive nitrogen balance, better hormonal profile, lower risk of infectious complications, with a reduction in mortality and risk of poor outcomes.

METHOD OF FEEDING: ENTERAL VERSUS PARENTERAL NUTRITION
The neurologically ill patients can be fed via enteral or parenteral route [Table 4]. The enteral nutrition can be provided either via gastric or jejunal routes. Some studies indicate that nitrogen balance is better with early jejunal or parenteral nutrition.[11] [12] [20] Unfortunately, none of the studies comparing parenteral nutrition with enteral nutrition are large enough to draw a conclusion, about which of the route is better. A recent meta-analysis that included five trials[10] [11] [20] [21] [22] concluded that there is a trend towards improved outcome with early parenteral nutrition. However, no statistical significance was achieved. In summary, both enteral and parenteral nutrition can be used for nutritional supplementation in patients with TBI. More emphasis should be given to nitrogen intake, nitrogen loss due to the hypercatabolism in these groups of patients.

#
NASOGASTRIC VERSUS NON-NASOGASTRIC FEEDING
The enteral feeding can be provided through a naso-gastric, naso-pyloric, naso-intestinal or with percutaneous gastrostomy routes [Table 5]. The nasogastric feeding can be associated with more risk of microaspirations, thus increasing the risk of pneumonia. One study showed that early nasojejunal feeding is well-tolerated despite the absence of bowel sounds.[12] The likelihood of incidence of pneumonia can be reduced by feeding via gastrostomy or transpyloric enteral feeding.[23] [24] A recently concluded meta-analysis of the available studies concluded small bowel feeding is associated with lower incidence of pneumonia and ventilator-assisted pneumonia. However, there was no difference in the length of ICU stay, the length of hospital stay and mortality in patients with either intestinal or gastric feeding.[25]

CONSTITUENTS OF NUTRITION: STANDARD DIET VERSUS IMMUNE ENHANCING DIET
Immunity enhancing agents such as arginine, glutamine, probiotics and omega 3 fatty acids can be used in addition to the standard diet used for supplementation of nutrition. The results of pooled data from trials using these agents show that used of these agents is associated with lesser risk of infection, reduction in the cytokine levels and inflammatory markers.[26] [27] [28]
#
NUTRITION IN PATIENTS WITH STROKE
The principles of nutrition are essentially same in stroke patients as that of TBI. However, 30–50% of stroke patients suffer from dysphagia during acute illness. This dysphagia gradually resolves over next 6 months, but still nearly 10% of patients experiencing persistent dysphagia.[29] Hence, these patients are at increased risk of malnutrition and dehydration due to poor oral intake. Not only this but also the patients are also at risk of infectious complications such as aspiration pneumonia.[30] [31] Hence, the outcome is worse in patients with dysphagia as compared to non-dysphagic stroke patients.
It is necessary to conduct a screening test for dysphagia in all acute stroke patients. The three most commonly performed tests are (1) water swallowing test,[32] (2) multiple consistency test[33] and (3) swallowing provocation test.[34] The low sensitivities or specificities of these tests preclude their routine use as a screening tool in patients with acute stroke.[35] Videofluoroscopic swallowing study (VFSS) and fibreoptic endoscopic evaluation of swallowing (FEES) are used for dysphagia screening. These tests have shown better predictive accuracy compared with the three clinical tests.[35] In VFSS, a non-ionic contrast agent is given to swallow, and all oral, pharyngeal and oesophageal structures can be visualised using fluoroscopy. In FEES, a fibreoptic bronchoscope is passed through the nose near pharynx and direct visualisation of the swallowing can be done. The FEES has advantages as it can be done bed-side, no radiation exposure and saliva of patients can be directly visualised.[36] Initially, in the acute stages, dysphagia screening can be done on daily basis and in later stages twice weekly. If dysphagia persists at the time of discharge, then once month evaluation is indicated for next 6 months.
Then incidence of malnutrition ranges from 24% to 48% in acute stroke patients.[37] This may be due to reduced oral intake due to dysphagia, poor level of consciousness and varying grades of cognitive dysfunction. Hence, any of the nutritional screening tools (stated earlier in the article) can be used for nutritional screening in these groups of patients. In the acute phases, a nasogastric feeding is beneficial due to the presence of dysphagia or poor Glasgow Coma Scale (GCS). Early tube feeding within 7 days showed a trend towards improved outcomes in stroke patients.[38] [39] Patients with poor GCS and on mechanical ventilation may benefit from early tube feeding. There are no trials comparing enteral or parenteral nutrition in these settings. The tube feeding should be initiated as early as possible, once the patient is stabilised. A nasogastric tube is sufficient for tube feeding in most of the patients. However, in patients with anticipated prolonged enteral feeding (>28 days), early feeding can be initiated through gastrostomy tubes.[23] Additional oral intake may be allowed in stroke patients depending on the severity of dysphagia. Parenteral nutrition is indicated when there is a contraindication for enteral nutrition, or the enteral nutrition fails to meet the demand for nutritional supplementation.
#
CONCLUSION
Patients with severe TBI and stroke are at risk of malnutrition due to the dysphagia, poor GCS, mechanical ventilation and hypercatabolism. Nutrition supplementation should be initiated as early as possible, and by 5–7 days should attain the full caloric requirement. Enteral or parenteral or combination of both can be considered for nutritional replacement. Intestinal feeding reduced the risk of pneumonia as compared to gastric feeding. Immune-enhancement diet can reduce the infectious complications in these patients.
