Impact of Persistent Inflammation-Immunosuppression-Catabolism Syndrome (PICS) on the Respiratory Physiology in Patients With Prolonged Mechanical Ventilation

Обзор

Past research on PICS has mainly focused on the predictability and prognosis of PICS occurrence in ICU patients. Still, there is currently insufficient research on the role of PICS in the care setting of patients who have stabilized and are transferred to respiratory care units such as Respiratory Care Centers (RCCs) for weaning attempts. To understand the impact of PICS on the respiratory physiology of patients undergoing weaning from prolonged mechanical ventilation, investigators propose a one-year research plan

Подробное описание

Past research on PICS has mainly focused on the predictability and prognosis of PICS occurrence in ICU patients. Still, there is currently insufficient research on the role of PICS in the care setting of patients who have stabilized and are transferred to respiratory care units such as Respiratory Care Centers (RCCs) for weaning attempts. To understand the impact of PICS on the respiratory physiology of patients undergoing weaning from prolonged mechanical ventilation, investigators propose a one-year research plan with the hypothesis that PICS endotype patients in the RCC setting are more likely to develop alveolar collapse during weaning trials, leading to decreased oxygenation function, increased respiratory burden, and potentially more lung injury from repeated alveolar collapse and reopening. Investigators plan to enroll 60 PMV patients admitted to the RCC, perform laboratory analyses to categorize patients as PICS endotype or other types, and then collect clinical data, respiratory physiology data, and biomarkers during weaning trials, such as changes in oxygenation, respiratory work and energy expenditure, infection occurrence, diaphragm ultrasound, esophageal pressure measurements, electrical impedance tomography, and inflammatory biomarkers. The expected research outcomes include the prevalence of PICS in stable PMV patients in the RCC setting and the differences in respiratory physiology and weaning outcomes between PICS and non-PICS patients, which could inform differentiated or personalized weaning strategies in the future.
