Inadequate initial trauma management might result in a high fatality rate. Moreover, unexpected injury results in changes to metabolism, inflammation, and haemodynamics. Enteral nutrition (EN) is strongly advised as a feeding access method rather than parenteral nutrition (PN) according to the American Society for Parenteral and Enteral Nutrition (ASPEN) standards. Enteral tube feeding is now the most widely used technique of providing nutritional support for critically ill individuals due to significant advancements in enteral formulations over the past several years. Formulas based on peptides comprise proteins that have undergone hydrolysis to yield peptides of different lengths. Here, we describe a patient's experience receiving postoperative intensive care unit (ICU) care while receiving dietary therapy. Enteral nutrition (EN) was not started for more than two weeks, despite the patient's lack of malnutrition at ICU admission. The present case study underscores the significance of nutrition interventions for critically ill trauma patients who are at increased risk of malnourishment. It demonstrates the efficaciousness of peptide-based high-protein, high-calorie, and appropriate nutrition therapy in meeting the patients' nutritional requirements and promoting prompt wound healing.
