ObjectiveTo describe a syndrome of acute neuromuscular respiratory failure (NM-ARF) caused by ICU-acquired acute myopathy and neuropathy.DesignCase series.SettingGeneral Regional University Hospital in Brescia, Italy.PatientsFive adult patients with NM-ARF after prolonged ICU stay and successful weaning from the ventilator and ICU discharge.InterventionsNone.MeasurementsClinical signs of NM-ARF, electroneurography and electromyography (ENMG) of peripheral nerves and muscles, and functional assessment of respiratory muscles.ResultsNM-ARF was diagnosed at the time of (one case), or 1-3 days after, ICU discharge. Limb weakness alarmed the physicians, while the signs of the NM-ARF were initially undetected. In the first observed case the acute respiratory failure was near fatal, and necessitated ICU readmission, while in the other cases 2 weeks of aggressive chest physiotherapy permitted resolution of the respiratory failure. History, clinical course and ENMG indicated the diagnosis of critical illness myopathy and neuropathy (CRIMYNE). Three patients recovered fully, while two had persisting evidence of axonal polyneuropathy several months after the onset.ConclusionsCritically ill patients with prolonged ICU stay, sepsis and MOF are at great risk of developing CRIMYNE, which in turn may be responsible for NM-ARF. This latter complication may arise after resolution of the respiratory and cardiac dysfunctions and successful weaning from the ventilator. As NM-ARF may cause unplanned ICU readmission or even unexpected death, strict clinical surveillance and monitoring of respiratory muscle function is recommended after discharge to the general ward of patients with proven NM-ARF. Early intensive chest physiotherapy can resolve the condition.
