Nerve excitability changes in critical illness polyneuropathy.
Patients in intensive care units frequently suffer muscle weakness and atrophy due to critical illness polyneuropathy (CIP), an axonal neuropathy associated with systemic inflammatory response syndrome and multiple organ failure. CIP is a frequent and serious complication of intensive care that delays weaning from mechanical ventilation and increases mortality. The pathogenesis of CIP is not we...
متن کاملCritical illness polyneuropathy in ICU patients is related to reduced motor nerve excitability caused by reduced sodium permeability
BACKGROUND Reduced motor and sensory nerve amplitudes in critical illness polyneuropathy (CIP) are characteristic features described in electrophysiological studies and due to dysfunction of voltage-gated sodium channels. Yet, faulty membrane depolarization as reported in various tissues of critically ill patients may cause reduced membrane excitability as well. The aim of this study was to com...
متن کاملThe Temporal Profiles of Changes in Nerve Excitability Indices in Familial Amyloid Polyneuropathy
Familial amyloid polyneuropathy (FAP) caused by a mutation in transthyretin (TTR) gene is an autosomal dominant inherited disorder. The aim of this study is to explore the pathophysiological mechanism of FAP. We prospectively recruited 12 pauci-symptomatic carriers, 18 patients who harbor a TTR mutation, p.A97S, and two-age matched control groups. Data of nerve excitability test (NET) from ulna...
متن کاملClinical review: Critical illness polyneuropathy and myopathy
Critical illness polyneuropathy (CIP) and myopathy (CIM) are major complications of severe critical illness and its management. CIP/CIM prolongs weaning from mechanical ventilation and physical rehabilitation since both limb and respiratory muscles can be affected. Among many risk factors implicated, sepsis, systemic inflammatory response syndrome, and multiple organ failure appear to play a cr...
متن کاملApproach to critical illness polyneuropathy and myopathy.
A newly acquired neuromuscular cause of weakness has been found in 25-85% of critically ill patients. Three distinct entities have been identified: (1) critical illness polyneuropathy (CIP); (2) acute myopathy of intensive care (itself with three subtypes); and (3) a syndrome with features of both 1 and 2 (called critical illness myopathy and/or neuropathy or CRIMYNE). CIP is primarily a distal...
