[Weaning from mechanical ventilation. Weaning categories and weaning concepts]

Area of Science:

• Critical Care Medicine
• Pulmonology
• Respiratory Therapy

Background:

• International weaning classification modified in German guidelines.
• Prolonged weaning subclassified into categories including noninvasive ventilation (NIV) use and weaning failure.
• Left heart failure is a significant factor in weaning failure and re-intubation.

Purpose of the Study:

• To outline updated German weaning guidelines.
• To detail strategies for preventing and managing prolonged mechanical ventilation weaning.
• To highlight the role of specialized weaning centers and multimodal therapy.

Main Methods:

• Review and modification of international weaning classification.
• Implementation of daily sedation interruption and spontaneous breathing trials (SBT).
• Early use of NIV for hypercapnic patients and management of left heart failure.

Main Results:

• Subclassification of prolonged weaning into distinct categories.
• Multimodal therapy in specialized centers achieves successful weaning in 50-60% of previously unweanable patients.
• Professional discharge management is crucial for home mechanical ventilation.

Conclusions:

• Updated German guidelines provide a refined approach to mechanical ventilation weaning.
• Multimodal therapy and specialized centers improve weaning success rates.
• Addressing comorbidities like left heart failure and improving out-of-hospital care are essential for successful weaning.
