ICU Acquired Weakness

• ICU acquired weakness (ICU-aw) is a general term that refers to the weakness that develops in critically ill patients during the course of their illness - especially in patients with sepsis and those receiving mechanical ventilation.
• ICU-aw is an very common complication of critical illness that can develop within hours and has been shown to increase the duration of mechanical ventilation and ICU/hospital LOS.  Observational studies have also reported an association with mortality.
• Risk factors associated with ICU-aw include medications (neuromuscular blocking agents, corticosteroids), hyperglycemia and immobility.
• For the critically ill ED patient, current recommendations suggest limiting the administration of neuromuscular blocking agents and corticosteroids, when possible.
