Ventilator Weaning in Prolonged Mechanical Ventilation-A Narrative Review

Area of Science:

• Critical Care Medicine
• Pulmonology
• Respiratory Therapy

Background:

• Prolonged mechanical ventilation (MV) impacts a significant patient subset, estimated at 10% of all MV cases.
• Care for patients on prolonged MV is less understood in post-intensive care unit (ICU) settings compared to acute care.
• This patient group often includes medically complex, elderly, and socioeconomically disadvantaged individuals, frequently at end-of-life.

Purpose of the Study:

• To review recent advancements in weaning strategies for patients requiring prolonged mechanical ventilation.
• To present outcomes associated with these novel weaning approaches.
• To offer insights into the multifaceted care challenges presented by prolonged MV.

Main Methods:

• Literature review focusing on recent studies and clinical practices in prolonged mechanical ventilation weaning.
• Analysis of outcomes data from various post-ICU and specialized care settings.
• Synthesis of information regarding care complexities for this patient population.

Main Results:

• Over 50% of patients considered unweanable in the ICU can be liberated from MV in post-acute settings.
• Home ventilation is increasingly utilized, alongside traditional ventilator weaning facilities and skilled nursing homes.
• Recent advances in weaning strategies are improving outcomes for prolonged MV patients.

Conclusions:

• Post-acute care settings play a crucial role in liberating patients from prolonged mechanical ventilation.
• Innovative weaning strategies are vital for managing the growing population requiring extended ventilatory support.
• Addressing the complexity of care for prolonged MV patients requires a multidisciplinary approach, considering patient-specific needs and evolving care models.
