Alisha et al reported prognostic factors for patients with pulmonary contusion following blunt chest trauma. This can help to identify a patient who may benefit from more aggressive management. The authors are from KLE University in Belgaum, India.
Patient selection: chest trauma
Clinical features of pulmonary contusion:
(1) dyspnea
(2) decreased exercise tolerance
(3) chest pain
(4) flail chest
(5) reduced chest expansion
Parameters:
(1) APACHE II at baseline
(2) SAPS II at baseline
(3) SOFA at baseline
(4) PaO2 to FIO2 ratio
(5) ventilator days
