Malnutrition is prevalent in patients with hepatic failure and remains an independent risk factor for morbidity and mortality in these patients. Factors that contribute to malnutrition in this patient population include altered metabolic rate, fat malabsorption, and impaired gastric emptying, all in the setting of an acute and potentially prolonged hospitalization. Acute liver failure (ALF), different from cirrhosis or chronic liver disease, is an uncommon but dramatic clinical syndrome that demonstrates severe and rapid decline in hepatic metabolic function. ⋯ Rates of survival from ALF have improved over recent years, but the rarity and severity of presentation have resulted in traditionally limited evidence to guide basic supportive care. Over time, advances in critical care management and the use of emergency liver transplantation have improved. In this article, we will review current nutrition considerations for patients with ALF.

Critically ill children in a pediatric intensive care unit (PICU) have unique nutrition needs that are challenging to achieve and thus are at high risk of malnutrition. There is increasing evidence that children who reach caloric goals early have improved outcomes. The purpose of this initiative was to implement an enteral nutrition (EN) algorithm in a tertiary care PICU utilizing clinical decision support tools (CDSTs) and a standardized order set within an electronic health record. ⋯ We used CDSTs and standardized order sets to implement a nutrition algorithm to facilitate and likely improve the nutrition care of critically ill children.

Multiple surgical procedures required by patients with extensive thermal injuries impedes delivery of adequate nutrition support, leading to caloric deficits, weight loss, delayed wound healing, and increased length of stay. The standard practice at our institution for >20 years has been to continuously infuse postpyloric enteral nutrition (EN) during surgery. The purpose of this review was to examine the safety and efficacy of intraoperative EN support. ⋯ EN has been safely provided with marginal intolerance during surgical procedures over the past 20 years. Continuous nutrition support with negligible interruption is integral to meet nutrient needs for wound healing, preservation of weight and nutrition parameters, and optimize length of stay in pediatric patients with extensive thermal injuries.

Vasodilatory shock, as observed in postoperative states and sepsis, is hallmarked by low systemic vascular resistance and low blood pressure compensated by increased cardiac output. Gasotransmitters, such as nitric oxide and hydrogen sulfide, are implicated in the development and perpetuation of vasodilatory shock. ⋯ Due to their nontoxic and pleotropic effects, micronutrients are being used as rescue therapy in postoperative vasoplegia and septic shock. Here, we outline the pathophysiology of vasodilatory shock, describe the rationale for vitamin B12 (hydroxocobalamin) in vasodilatory shock, and identify literature evaluating its use in vasoplegic states.

Mechanically ventilated patients are unable to take food orally and therefore are dependent on enteral nutrition for provision of both energy and protein requirements. Enteral nutrition is supportive therapy and may impact patient outcomes in the intensive care unit. ⋯ Nutrition support is unique for patients on mechanical ventilation and, as recently published literature shows, should be tailored to the individuals' underlying pathology. This review will discuss the most current literature and recommendations for enteral nutrition in patients receiving mechanical ventilation.
