Noninvasive Ventilatory Support In The Management Of Acute Lung Injury After Thoracic Trauma By Acomplex Critical Ventilator

Objective:To evaluate the effect of noninvasive ventilatory support (NIV) in the management of acute lung injury(ALI) after thoracic trauma by acomplex critical ventilator.Methods:A prospective study which involve 47 patients suffered ALI after thoracic trauma.All the patients were randomized into 2 groups,one group involved 21 patients with NIV ,another group involved 26 patients with invasive mechanical ventilation (IMV) ,Changes of PaO₂ , ratio of partial of arterial oxygen to the fraction of inspired oxygen(PaO₂/FiO₂) , respiratory rate(RR) and score of the accessory respiratory muscle use were measured at different time (before ventilation, 1 hours and 12 hours after ventilation , and after weaning , respectively) . Meanwhile the mortality , ventilation duration , complications of ventilation and hospitalization duration were recorded .Results:PaO₂ , PaO₂/FiO₂ , RR and score of the accessory respiratory muscle use of the patients with ALI were improved significantly after acomplex critical ventilator (P<0.05).The ventilation duration , complications of ventilation and hospitalization duration of NIV were short of IMV's . But the mortality between the two groups has no difference significantly (P>0.05) .Conclusion:Using NIV through acomplex critical ventilator early is an effective way to treat ALI after thoracic trauma . Meantime IMV always play the key work of ALI even ARDS after thoracic trauma .
