Nutritional Support for Necrotizing Soft Tissue Infection Patients: From ICU to Outpatient Care

Area of Science:

• Metabolic Medicine
• Clinical Nutrition
• Infectious Diseases

Background:

• Necrotizing soft tissue infections (NSTIs) share some nutritional parallels with burn injuries.
• However, NSTIs elicit a unique metabolic stress response.
• This response involves inflammatory and neuroendocrine changes, impacting nutrient metabolism.

Purpose of the Study:

• To highlight the distinct nutritional requirements for patients with NSTIs.
• To emphasize the phased recovery approach for NSTI patients.
• To underscore the need for tailored nutrition management.

Main Methods:

• Analysis of metabolic and inflammatory pathways in NSTIs.
• Identification of four distinct recovery phases (Early Acute, Late Acute, Persistent Inflammation, Immunosuppression, and Catabolism Syndrome, Recovery).
• Assessment of nutrition risk screening, malnutrition, and micronutrient deficiencies.

Main Results:

• NSTI metabolic response differs significantly from burn injuries.
• A phased recovery model necessitates specific nutritional interventions.
• Energy expenditure and protein needs require close monitoring.
• Post-ICU and post-discharge nutrition intake is frequently insufficient.

Conclusions:

• NSTI nutrition management requires a specialized, phase-specific approach.
• Continuous monitoring of nutrition intake is vital until nutritional status is fully restored.
• Early and ongoing nutritional intervention is key for optimal patient outcomes.
