Temporal Change in Parasternal Thickening Fraction as a Predictor for Weaning

Temporal Changes in Parasternal Intercostal Muscle Thickening as a Possible Biomarker for Successful Weaning From Mechanical Ventilation: a Prospective Observational Study

optimal time to liberate from mechanical ventilation is highly prioritized since improper extubation time lead to serious consequences

Several parameters were proposed to assess proper weaning time including diaphragmatic ultrasound and extra-diaghragmatic muscles. previous research concluded an ability of parasternal intercostal (PIC) thickening to predict weaning outcomes. researchers of current study assumed that temporal changes in PIC thickening would provide greater ability to predict weaning outcomes

Inclusion Criteria:

- Mechanically ventilated for 24 hours or more ready for weaning

Exclusion Criteria:

• Refusal Tracheostomized Inability to obtain ultrasound views patients with neuromuscular disease
