Repair of Pulmonary Vein Injury in Trauma

Immediate Recognition and Resuscitation

Patients with identified bleeding sources and hemodynamic instability require immediate surgical bleeding control rather than prolonged resuscitation attempts, as recommended by the Critical Care society 1, 2
During initial resuscitation, maintaining normoventilation (PaCO2 5.0-5.5 kPa) and avoiding hyperventilation is crucial, as it worsens outcomes in trauma patients through decreased cerebral perfusion and cardiovascular collapse, according to the Critical Care society 3

The Critical Care society recommends initiating lung-protective ventilation with low tidal volumes (<6 mL/kg predicted body weight) and moderate PEEP immediately postoperatively to prevent acute lung injury 3
The World Journal of Emergency Surgery suggests beginning mechanical thromboprophylaxis immediately in all patients without absolute contraindications, and starting LMWH-based pharmacologic thromboprophylaxis within 48-72 hours of injury once hemostasis is secured 5
Early enteral feeding should begin within 72 hours when hemodynamically stable and not requiring vasopressor support, as recommended by the World Journal of Emergency Surgery 5

Avoid hyperventilation during resuscitation, as PaCO2 <27 mmHg causes neuronal injury, cerebral vasoconstriction, and impaired venous return leading to cardiovascular collapse, according to the Critical Care society 3
The Critical Care society advises against using high tidal volumes (>6 mL/kg), as even short-term ventilation with 12 mL/kg promotes pulmonary inflammation and coagulation abnormalities 3
