The History of Critical Care Nutrition: Seventy-Five Years of Evolution.

Crit Care Clin

April 2025

Division of Gastroenterology, Hepatology, and Nutrition, Department of Medicine, University of Louisville School of Medicine, Louisville, KY, USA.

In its infancy during the formation of the specialty of critical care medicine, the need for safe and effective nutritional therapy was recognized as a key component of the care for severely ill patients admitted to an intensive care unit. The origin of modern critical care nutrition can be traced back to the invention of total parenteral nutrition, which enabled the delivery of long-term nutritional support to critically ill adults who had insufficient absorption or access to the gastrointestinal tract. This report discusses the rationale for these innovations and summarizes the events leading up to our current state of patient management in critical care nutrition.

Neonates who require gastrointestinal surgery are a complex group of patients that require special consideration with regard to nutritional supplementation and growth. During the acute postoperative phase, a major stress response causes catabolism with degradation of the body's nutrient stores leading to poor growth. Following surgery, parenteral nutrition is often required to support the surgical neonate; although, enteral nutrition, if feasible, is critical because it helps improve intestinal adaptation.

Background: The insertion of an enterogastric tube (oral or nasal) (EGT) is the passage of a tube through the nose or mouth into the stomach. In a paediatric setting, EGTs are used within clinical practice for a variety of reasons including enteral feeding, decompression, post-gastrointestinal surgery, patient assessment, and drug and fluid administration. Confirmation of EGT placement is required immediately following insertion and thereafter prior to each use, including after the administration of enteral feed or medication.

Reduced efficacy of oral diuretics in the treatment of congestive heart failure (CHF) can be secondary to reduced enteral drug absorption. The aim of this study was to determine the efficacy of subcutaneous (SC) furosemide administration to control the signs of refractory CHF in dogs and cats and to assess the feasibility of this route of administration. The clinical records of 13 dogs and 17 cats with a history of refractory CHF treated with subcutaneous (SC) furosemide were reviewed retrospectively.
