Why carry out this study?

Survivors of aneurysmal subarachnoid hemorrhage (aSAH) may require prolonged intubation with mechanical ventilation (MV).

However, the risk factors for prolonged intubation in these patients are still unclear.

What was learned from this study?

A history of diabetes mellitus and Hunt and Hess grade 3–5 independently predict prolonged MV in aSAH patients.

Predicting the possibility of prolonged MV can help neurocritical patients benefit from tracheostomy and avoid unnecessary complications.
