Técnicas de aislamiento pulmonar selectivo

starting from 1930, several techniques of lung isolation has been developed, generating an important evolution in anesthesia, mainly in cardiothoracic anesthesia, improving the knowledge of lung physiology, so interventions that require lung isolation are better every time. the purpose of the separation or lung isolation, is the selective interruption of the ventilation in a lung (total pulmonary collapse) or a portion of the lung (selective lobar collapse). as the clinical indications for the lung isolation have expanded, limitations have arisen for the use of the double-lumen tubes. for this reason, alternatives for lung isolation, such as bronchial blockers have become important options. at the present time, despite having so many devices, there have not been randomized studies demonstrating the superiority of one device over another.
