Intensive care unit (ICU) patients often experience significant metabolic and inflammatory stress that drastically alters their body's nutritional requirements. During such hypermetabolic periods, the body's synthesis of certain amino acids can no longer keep pace with the high demand, transforming previously nonessential nutrients into conditionally essential ones.

Malnutrition is common in critically ill patients, affecting up to 40% of those in the ICU and worsening with prolonged stays. In cases where a patient's gastrointestinal tract is non-functional, parenteral nutrition in the ICU becomes a life-saving method for delivering vital nutrients intravenously.

Malnutrition is a common and serious complication for critically ill patients, with research indicating its prevalence can be as high as 78% in intensive care units (ICUs). The incidence of malnutrition among ICU patients varies depending on the population, assessment tool, and duration of stay, but studies confirm it poses a significant risk to patient outcomes. This article explores the scale of the problem and the factors contributing to the alarmingly high rates of malnutrition in critical care settings.

According to a 2021 study, increased early protein provision was significantly associated with reduced 30-day and 6-month mortality in acute critically ill stroke patients. This finding challenges the conventional approach of delayed or insufficient nutritional support, emphasizing the critical role of timely protein delivery in improving survival outcomes for this vulnerable population.

According to research, around 10-15% of critically ill patients are unable to receive adequate nutrients through the gut, making them candidates for parenteral nutrition (PN). This intravenous feeding method is vital for those with non-functional gastrointestinal tracts, severe malabsorption, or other conditions preventing oral or enteral feeding.

According to the American Society for Parenteral and Enteral Nutrition (ASPEN), refeeding syndrome involves a potentially fatal shift in fluids and electrolytes, with hypophosphatemia being a central hallmark. Identifying the phosphorus level that indicates this syndrome is critical for managing at-risk patients, often those who have experienced prolonged periods of malnutrition.

According to scientific literature, up to 50% of hospitalized patients may be malnourished or at risk of malnutrition upon admission. To combat this, guidelines from accrediting bodies, such as the Joint Commission (JCAHO), universally mandate nutritional screening for all hospital inpatients within 24 hours of arrival. This prompt action is a cornerstone of effective patient care and significantly impacts clinical outcomes.

According to StatPearls, enteral nutrition is the preferred feeding method over parenteral nutrition due to its effectiveness, lower infection risk, and preservation of gut function. Patients who cannot meet their nutritional needs orally, but have a functional gastrointestinal tract, are the primary candidates for receiving enteral nutrition.

With estimates suggesting that 10-60% of hospitalized patients are malnourished and require nutritional support, the optimal delivery method is a frequent topic of debate. This article explores the question: Is bolus or continuous feeding better? We will break down the key differences, advantages, and disadvantages of each approach, helping to clarify how the best choice is determined by the patient's specific clinical needs.

Acute respiratory distress syndrome (ARDS) is a critical condition characterized by severe lung inflammation and impaired gas exchange. Patients suffering from ARDS are in a hypercatabolic state, dramatically increasing their protein needs compared to healthy individuals. This necessitates a high protein intake, often in the range of 1.2 to 2.0 grams of protein per kilogram body weight daily for patients with acute respiratory distress syndrome (ARDS) may require, to mitigate muscle wasting and support tissue repair.
