NCT05726500

Brief Summary

The goal of this clinical trial is to evaluate regional ventilation distribution in patients admitted to the intensive care unit after emergent laparotomy due to abdominal sepsis. The main question it aims to answer is: • evaluate if patients admitted after an open abdomen strategy have a different regional ventilation distribution compared to patients in which abdomen is closed at the end of the procedure Participants will undergo non-invasive monitoring (esophageal pressure and electrical impedance tomography) and an blood gas analysis samples. Researchers will compare open abdomen group and closed abdomen group to see if the ventilation distribution pattern is different.

Outcome Measures

Primary Outcomes (3)

  • Chest-wall compliance (Ccw) measured using respiratory parameters from the Ventilator

    Different chest wall compliance between the two groups measured using the esophageal catheter. Chest wall compliance will be calculated using the data provided from the respiratory monitoring (i.e. esophageal balloon catheter).

    Day 0

  • Chest-wall compliance (Ccw) measured using respiratory parameters from the Ventilator

    Different chest wall compliance between the two groups measured using the esophageal catheter. Chest wall compliance will be calculated using the data provided from the respiratory monitoring (i.e. esophageal balloon catheter).

    Day 1

  • Chest-wall compliance (Ccw) measured using respiratory parameters from the Ventilator

    Different chest wall compliance between the two groups measured using the esophageal catheter. Chest wall compliance will be calculated using the data provided from the respiratory monitoring (i.e. esophageal balloon catheter).

    Day 2

Secondary Outcomes (5)

  • Regional ventilation distribution measured using Electrical impedance tomography

    Day 0

  • Regional ventilation distribution measured using Electrical impedance tomography

    Day 1

  • Regional ventilation distribution measured using Electrical impedance tomography

    Day 2

  • Mortality in the intensive care unit

    Up to 28 days

  • Infection rate during ICU stay

    Up to 28 days
