Summary

Critical illness neuromuscular abnormalities (CINMA) affect 25% of ICU survivors, causing limb weakness. Risk factors include prolonged ventilation and high blood sugar, highlighting the need for better prevention strategies.

Area of Science:

  • Critical care medicine
  • Neurology
  • Intensive care unit (ICU) acquired conditions

Context:

  • Critical illness neuromuscular abnormalities (CINMA) affect 25% of patients in the intensive care unit (ICU) upon regaining consciousness.
  • CINMA present as bilateral, symmetric limb weakness, sparing facial muscles, with electrophysiological findings of axonal sensory motor polyneuropathy and/or myopathy.
  • Key risk factors include prolonged multiple organ failure, mechanical ventilation, corticosteroid use, and hyperglycemia.

Purpose:

  • To summarize the characteristics, risk factors, and impact of CINMA.
  • To highlight the contribution of CINMA to prolonged mechanical ventilation, particularly due to diaphragm weakness.
  • To identify gaps in preventive measures and suggest areas for future research, such as strict blood glucose control.

Summary:

  • CINMA are common in ICU survivors, characterized by significant limb weakness.
  • Risk factors are linked to the severity and management of critical illness.
  • CINMA prolongs mechanical ventilation duration and recovery time, with a median limb weakness of 21 days.

Impact:

  • CINMA significantly impacts patient recovery, increasing the duration of mechanical ventilation and overall hospital stay.
  • Understanding CINMA's risk factors can guide the development of targeted preventive strategies.
  • Further research is needed to confirm the efficacy of interventions like strict glycemic control in diverse ICU populations.
