Lung Protective Ventilation Strategies: Have We Applied Them in Trauma Patients at Risk for Acute Lung Injury and Acute Respiratory Distress Syndrome?
Lung protective ventilation strategies for patients with acute lung injury (ALI) and acute respiratory distress syndrome (ARDS) are well documented, and many medical centers fail to apply these strategies in ALI/ARDS. The objective of this study was to determine if we apply these strategies in trauma patients at risk for ALI/ARDS. We undertook a retrospective review of trauma patients mechanically ventilated for ≥4 days with an ICD-9 for traumatic pneumothorax, hemo-thorax, lung contusion, and/or fractured ribs admitted from May 1, 1999 through April 30, 2000 (Group 1), the pre-ARDS Network study, and from May 1, 2003 through April 30, 2004 (Group 2), the post-ARDS Network study. Tidal volume (VT)/kg admission body weight, VT/kg ideal body weight (IBW), and plateau and peak pressures were analyzed with respect to mortality. VT/Kg admission body weight and IBW were significantly reduced when comparing Group 1 with Group 2 (9.27 to 8.03 and 11.67 to 10.04, respectively). VT/kg IBW was greater (P < 0.01) for patients who died in Group 1 (13.81) compared with patients who lived (10.29) or died (9.89) in Group 2. Peak and plateau pressures were greater (P < 0.01) in patients who died in Group 1 than patients who lived or died in Group 2. A strict ARDS Network ventilation strategy (VT < 6 mL/kg) is not followed, rather a low plateau/peak pressure strategy is used, which is a form of lung protective ventilation.
