Krause and Mahans Food the Nutrition Care Process, 15e

What it’s about

This chapter provides a comprehensive guide to medical nutrition therapy for patients in critical care settings. It delves into the unique metabolic responses to stress, trauma, burns, sepsis, and major surgery, offering evidence-based guidelines for assessing nutritional needs and implementing effective nutrition support. Readers will learn how to determine energy and protein requirements, manage fluid and electrolyte balance, and apply specialized feeding strategies like enteral and parenteral nutrition. The chapter addresses specific patient populations, including the obese and those with an open abdomen or major burns, providing practical advice to attenuate the metabolic response, prevent cellular injury, modulate the immune response, and ultimately improve patient outcomes, reduce ICU stays, and decrease mortality.

The through-line

Who it’s for

A clinician (dietitian, doctor, nurse) working in an intensive care unit (ICU) who wants to provide the best possible care for their critically ill patients and improve outcomes like mortality, length of stay, and infection rates.

The problem

Critically ill patients have complex and rapidly changing nutritional needs due to hypermetabolism and hypercatabolism, making it difficult to provide appropriate nutrition support. The clinician feels uncertain and overwhelmed by the conflicting information and the high stakes involved, fearing they might harm the patient through overfeeding, underfeeding, or choosing the wrong feeding method.

The plan

1. Accurately assess the patient's nutritional status and risk using appropriate tools (e.g., physical assessment, NUTRIC score) and determine energy needs (ideally via indirect calorimetry).
2. Initiate early nutrition support (preferably enteral nutrition within 24-48 hours) once the patient is hemodynamically stable.
3. Provide appropriate macro- and micronutrients, focusing on high protein (1.2-2.0 g/kg/day) and avoiding overfeeding, while maintaining moderate glycemic control.
4. Tailor the nutrition prescription to specific conditions like burns, trauma, or surgery, and monitor tolerance and clinical status continuously.

The payoff

The clinician becomes a confident and effective practitioner who significantly improves patient outcomes, reducing disease severity, length of stay, and mortality. · Their patients heal faster, have fewer infections, and experience a smoother recovery.
