Introduction:
In the intensive care unit (ICU), plasmapheresis is used for critically ill patients, but data on plasma exchange practices, techniques, and indications in the ICU are limited. This study aims to describe the management of plasma exchange in the ICU at Clermont-Ferrand University Hospital.
Methods:
This retrospective observational study analyzed patients who underwent therapeutic plasma exchange (TPE) via centrifugation or double filtration plasmapheresis (DFPP). Secondary analyses compared these techniques and their impact on in-hospital mortality.
Results:
From 2011 to 2021, 196 patients received TPE. Common comorbidities included cardiovascular (42.3%), neurological (25.5%), and renal conditions (27.6%). Primary indications were thrombotic microangiopathies (25%), autoimmune neurological diseases (26%), and renal transplant rejection (18%). Centrifugation, the predominant technique, was used for critically ill patients, while DFPP was preferred for immune graft rejection and neurological diseases.
Conclusions:
Selection bias likely influenced results, as technique choice depended on indication. The optimal approach for autoimmune neurological diseases remains unclear, warranting further investigation.

A pleural effusion is the abnormal collection of fluid between the parietal and visceral pleura layers of tissue that form the lining of the lungs and chest cavity. It can occur independently or due to surrounding parenchymal diseases, such as infection, malignancy, or inflammatory conditions.
