Overview

This study aims to evaluate the prognostic significance of CLI in predicting 28-day mortality and other outcomes in critically ill patients who develop post-operative abdominal sepsis.

Eligibility

Inclusion Criteria:

Age ≥ 18 years.

Postoperative secondary peritonitis requiring ICU admission, with clinical evidence of:

Diffuse or localized abdominal pain/tenderness. Peritoneal signs (e.g., guarding, rigidity, rebound tenderness). Imaging or intraoperative confirmation of purulent/exudative intra-abdominal fluid.

Systemic inflammation (e.g., fever, leukocytosis, or vasopressor requirement). Sepsis diagnosis per Sepsis-3 criteria: Suspected/confirmed infection with acute increase in SOFA score ≥2 points (6).

Anticipated ICU stay ≥48 hours postoperatively.

Exclusion Criteria:

  • Pregnancy
    • Advanced liver disease (Child-Pugh class B or C) that might independently affect albumin levels
    • Advanced kidney disease (CKD stage 4 or 5) or patients on chronic dialysis
    • Expected mortality within 48 hours of ICU admission
    • Patients with primary peritonitis or tertiary peritonitis
    • Immunocompromised patients (e.g., on chronic immunosuppressive therapy, solid organ transplant recipients, patients with HIV and CD4 count \<200/mm³)
    • Patients with pre-existing systemic inflammatory diseases that might affect baseline CRP levels
    • Patients participating in interventional trials that might affect outcomes

FAQs

Learn more about clinical trials

What is a clinical trial?

A clinical trial is a study designed to test specific interventions or treatments' effectiveness and safety, paving the way for new, innovative healthcare solutions.

Why should I take part in a clinical trial?

Participating in a clinical trial provides early access to potentially effective treatments and directly contributes to the healthcare advancements that benefit us all.

How long does a clinical trial take place?

The duration of clinical trials varies. Some trials last weeks, some years, depending on the phase and intention of the trial.

Do I get compensated for taking part in clinical trials?

Compensation varies per trial. Some offer payment or reimbursement for time and travel, while others may not.

How safe are clinical trials?

Clinical trials follow strict ethical guidelines and protocols to safeguard participants' health. They are closely monitored and safety reviewed regularly.
