[Selective lobar blockade using an arndt endobronchial blocker in 2 patients with respiratory compromise who underwent lung resection].

Selective lobar blockade is an alternative to one-lung ventilation in thoracic surgery. We present 2 cases of lung resection with severe respiratory compromise. The first patient had previously undergone a left lower lobectomy and 2 atypical resections in the left and right upper lobes and was scheduled for a right lower lobectomy. The second patient presented chronic obstructive pulmonary disease with forced vital capacity of 1200 mL (26% of predicted value) and forced expiratory volume in 1 second of 820 mL (25% of predicted value) and was scheduled for an atypical resection of the left upper lobe with pleural abrasion. Selective lobar blockade was achieved in both cases using an Arndt endobronchial blocker. Ventilation during the operation was sufficient. Surgery was uneventful in both cases and lobar collapse was satisfactory.
