To describe the anaesthetic implications of permissive hypercapnia resulting from deliberate hypoventilation to limit peak airway pressures during thoracic surgery in patients with severe emphysema.
Retrospective review of 13 patients with severe emphysema undergoing thoracic surgery under comparable anaesthetic regimens.
Patients were categorized into a normocapnia group (n=3) and a hypercapnia group (n=10, defined by PaCO2 >70 mmHg resulting from restricted peak airway pressures).
In the hypercapnia group, PaCO2 reached 70–135 mmHg (mean 98±21 mmHg); all 10 patients required inotropic support for hypotension, 4 required tracheal oxygen insufflation, and 3 received lidocaine for ventricular arrhythmia.
Nine of 10 hypercapnic patients achieved tracheal extubation in the operating theatre with no postoperative organ dysfunction.
Prolonged postoperative air leak lasting beyond 5 days occurred in 1 of 10 hypercapnic patients compared to 2 of 3 normocapnic patients (mean PaCO2: 45±1 mmHg).

Implication

Retrospective study reveals manageable hemodynamic events with permissive hypercapnia in thoracic surgery for emphysema, indicating severe hypoventilation is clinically tolerated.
