Brief summary

Cough strength score will give true prediction of Extubation outcome

Detailed description

Head trauma patients were evaluated for readiness to be weaned off mechanical ventilation. If they had completed an Spontaneous Breathing Trial (SBT) before extubation. To measure Semiquantitative Cough Strength Score (SCSS), the investigator will put the patients at 30° to 45°, measure SCSS, first. The investigator enhance the patient to cough with as much effort as, when the investigator disconnect the ventilator. The cough strength was scored from 0 to 5 as follows: 0 = no cough on command, 1 = audible movement of air through the endotracheal tube but no audible cough, 2 = weakly (barely) audible cough, 3 = clearly audible cough, 4 = stronger cough and 5 = multiple sequential strong coughs.

Healthy volunteers

Inclusion criteria

* The study included 80 adult male and female patients' their ages between 18-65 years admitted to trauma ICU with head trauma, on mechanical ventilation more than 24 hours and was ready to be weaned off from mechanical ventilation after successful spontaneous breathing trial and Glasgow Coma Scale (GCS) score \> 8 before extubation

Exclusion criteria

• Patients who had undergone tracheostomy before extubation, GCS ≤ 8, chest trauma (ribs fracture and lung contusion) and patients with chronic chest disease (Chronic obstructive pulmonary disease, tuberculosis and cancer lung) were excluded from the study.

Design outcomes

Primary

Measure	Time frame	Description
Extubation outcome (success or failure), is the patient reintubate again or not and it's correlation with the level of Cough Strength Score	within 6 hours postextubation	The cough strength was scored from 0 to 5 as follows: 0 = no cough on command, 1 = audible movement of air through the endotracheal tube but no audible cough, 2 = weakly (barely) audible cough, 3 = clearly audible cough, 4 = stronger cough and 5 = multiple sequential strong coughs.
