Background. The purpose of this study was to determine the safety and
feasibility of whole gut washout for severe sepsis in human beings. Me
thods. High-volume polyethylene glycol-3500 was administered to patien
ts with severe sepsis. Body temperature, white blood cell count, and v
entilatory indexes were recorded 24 hours before and 24 hours after wh
ole gut washout. Results. A significant decrease in febrile response w
as observed after gut washout with polyethylene glycol. Improvements i
n PaO2, positive end-expiratory pressure, and peak airway pressure wer
e observed. The washout was well tolerated in all but one patient. Con
clusions. High-volume whole gut washout for severe sepsis appears safe
in critically ill patients and may offer some promise in reducing ent
erogenic inflammation after catabolic stress.
