Input: Question: Do the use of theraputic plasma exchange ( TPE ) in the setting of refractory burn shock?
Answer: This is the largest study to date examining TPE as an adjunct in burn resuscitation and suggests that TPE may be effective as a salvage intervention for refractory burn shock. Physiologic parameters clearly improved after the use of TPE without any detected adverse consequences. Also, admission lactate may be a useful indicator to determine who will fail standard burn resuscitation and require TPE.
Output:
yes
