Lung isolation in patients with previous lung resections: Selective sequential lobar blockade using a Fuji Uniblocker® endobronchial blocker. / Aislamiento pulmonar en pacientes con resecciones pulmonares previas: bloqueo lobular selectivo secuencial con bloqueador bronquial Fuji Uniblocker®.

Lung isolation is essential during thoracic surgery, as it allows the thoracic surgeon to visualise and work in the surgical field. The occurrence of hypoxaemia during lung isolation is common, and is even more so in patients with decreased pulmonary functional reserve. The clinical cases are presented of 2 patients with a history of left pulmonary resections (1st left lower lobectomy, 2nd left lower lobectomy and left upper lobe segmentectomy), in which sequential selective lobar blockade was performed with Fuji Uniblocker® endobronchial blocker for performing right lung atypical resections (right upper lobe, middle lobe, and right lower lobe). In our experience the technique was successful, the surgical field was optimal and no intra- or post-operative complications were found. This technique may be an alternative to traditional lung isolation in patients with compromised respiratory function (low functional reserve or previous contralateral lung resections).
