| Sumario: | Treatment of pulmonary contusion when adequately established is very simple in most cases. Pathophysiological changes occur as a result of the effects produced by loss of chest wall integrity, accumulation of fluid in the pleural cavity, obstruction of the airways and lung dysfunction. The alveolar recruitment maneuver is the reopening of collapsed lung areas by increasing inspiratory pressure in the airway. The primary objective of this case report was to evaluate the effectiveness of the alveolar recruitment maneuver in a patient with pulmonary contusion. A 33 year old male patient, with a clinical condition of bilateral chest trauma and traumatic brain injury, evolved with reduction of the level of consciousness, acute respiratory failure, hypovolemic shock and hemoptysis. The patient underwent thoracentesis, bilateral thoracic drainage and was also submitted to invasive mechanical ventilation. After 48 hours of invasive mechanical ventilation, in accordance with protective strategy an alveolar recruitment maneuver mode, pressure-controlled ventilation, pressure controlled 10 cmH2O, respiratory rate 10 rpm, inspiratory time 3.0, positive end-expiratory pressure 30 cmH2O and FI0(2) 100%, for two minutes. After the alveolar recruitment maneuver, the patient presented clinical pulmonary improvement, but there was a variation of 185 to 322 of Pa0(2)/FiO2 (arterial partial pressure of oxygen/ fraction of inspired oxygen). He was discharged from the intensive care unit 22 days after admission. The alveolar recruitment maneuver in this patient showed significant results in the treatment of pulmonary contusion, improving blood oxygenation, preventing alveolar collapse and reversing atelectasis. |
