Bronchopleural Fistula (BPF)
Considerations
-
Etiology of BPF & associated urgency:
-
Trauma, empyema/abscess, bullous disease, post lung resection, carcinoma
-
-
Comorbid disease:
-
Chronic obstructive lung disease, malignancy, coronary artery disease, arrhythmias
-
-
Absolute indication for lung separation:
-
Pathophysiological impact of positive pressure ventilation
-
Ineffective ventilation (with chest tube in place)
-
Tension pneumothorax (without chest tube in place)
-
Systemic air embolus
-
-
Protection of healthy lung from soiling
-
-
Repeat thoracotomy considerations:
-
Hemorrhage
-
Sepsis, septic shock
-
Postoperative analgesia
-
Postoperative ICU disposition for PPV
-
Goals & Conflicts
-
Need for lung isolation prior to PPV in order to prevent pathophysiological complications as outlined above
-
Balanced with possible full stomach, difficult airway, hemodynamic instability, limited functional reserve
-
Rapid sequence lung isolation techniques:
-
Regional anesthesia
-
Awake fibreoptic intubation: single lumen ETT +/- bronchial blocker, double lumen ETT prior to GA
-
Asleep intubation with spontaneous ventilation prior to isolation
-
Modified RSI with no or limited PPV prior to lung isolation
-
Double lumen ETT preferred to bronchial blocker to support suctioning, optimal ventilation & isolation
-
-
Need for resuscitation & stabilization prior to OR:
-
Fluids, vasopressors, antibiotics, chest tube placement
-
If no chest tube in place prior to OR, thoracic surgeon must be immediately available to place a chest tube
-
-
Intraoperative goals:
-
Lung protective ventilation
-
Restrictive fluid strategy
-
Maintenance of normothermia & normal metabolics
-
-
Optimization to facilitate postoperative extubation:
-
Resuscitation
-
Bronchial suctioning
-
Bronchodilators
-
Extubation to BiPAP
