From the Guidelines

The management of inflammatory response should prioritize early recognition and treatment, as delayed diagnosis can lead to a higher risk of poor outcomes, and a prompt diagnosis, adequate resuscitation, early initiation of appropriate antibiotic therapy, and early and effective source control are key factors in the effective treatment of intra-abdominal infections 1. The inflammatory response is a complex process that involves the recognition of harmful stimuli, activation of immune cells, and release of inflammatory mediators. In the context of intra-abdominal infections, the inflammatory response can lead to sepsis, a life-threatening condition that requires prompt recognition and treatment. The Third International Consensus Definitions for Sepsis and Septic Shock (Sepsis-3) defines sepsis as life-threatening organ dysfunction caused by a dysregulated host response to infection, and septic shock as a subset of sepsis that requires vasopressor support to maintain blood pressure and has a high serum lactate level 1. Some key factors to consider in the management of inflammatory response include:

  • Early recognition of sepsis using simple diagnostic criteria based on physical examination findings, such as the quick SOFA (qSOFA) score, which includes variables such as Glasgow Coma Scale score, systolic blood pressure, and respiratory rate 1
  • Prompt diagnosis and adequate resuscitation to prevent organ dysfunction and improve outcomes 1
  • Early initiation of appropriate antibiotic therapy to reduce the risk of sepsis and improve survival 1
  • Early and effective source control to prevent the spread of infection and reduce the risk of complications 1
  • Reassessment of the clinical response and adjustment of the management strategy as needed to ensure optimal outcomes 1 It is also important to consider the role of lifestyle factors, such as diet, exercise, stress management, and adequate sleep, in influencing inflammatory processes in the body. Additionally, medications like NSAIDs, corticosteroids, or disease-modifying drugs may be necessary to manage excessive or prolonged inflammation, depending on the underlying cause. In terms of grading the recommendation, the management of inflammatory response in the context of intra-abdominal infections would be classified as a strong recommendation (1A), as the benefits of early recognition and treatment clearly outweigh the risks and burdens, and the quality of supporting evidence is high, based on recent guidelines and consensus definitions 1.

From the Research

Inflammatory Response Mechanisms

  • The inflammatory response is a physiological process that aims to restore tissue homeostasis 2
  • Uncontrolled or unresolved inflammation can cause tissue damage and contribute to chronic inflammatory and autoimmune diseases 2

Resolution of Inflammation

  • Resolution of inflammation is an active process that relies on the production of pro-resolving molecules and activation of intracellular pathways 2
  • Pharmacological strategies can accelerate resolution in animal models of acute inflammation by mimicking or inducing natural pathways of resolution phase of inflammation 2

Nonpharmacological Treatment Strategies

  • Heat and cold therapy modalities are used to reduce pain and promote healing in acute musculoskeletal injury 3
  • Cold therapy can reduce pain, blood flow, edema, inflammation, muscle spasm, and metabolic demand 3
  • Heat therapy can provide pain relief and increase blood flow, metabolism, and elasticity of connective tissues 3

Efficacy of Heat and Cold Therapies

  • There is limited evidence from randomized clinical trials (RCTs) supporting the use of cold therapy following acute musculoskeletal injury and delayed-onset muscle soreness (DOMS) 3
  • RCTs have shown that heat-wrap therapy provides short-term reductions in pain and disability in patients with acute low back pain and provides significantly greater pain relief of DOMS than does cold therapy 3
