AbstractDifferential lung ventilation to achieve optimised ventilation for each lung is a procedure rarely used in the intensive care unit, to treat select cases of severe unilateral lung disease in intensive care. However, existing techniques both for securing the airway and ventilating the lungs are challenging and have complications. We present the use of differential lung ventilation in the intensive care setting, securing the airway with a technique not previously described, using endotracheal tubes inserted through a tracheotomy and orally. In the course of 1 month, we treated three patients with unilateral atelectatic and consolidated lungs by differential lung ventilation. The left lung was ventilated through an endotracheal tube inserted into the left main stem bronchus through a tracheotomy. The right lung was ventilated through an endotracheal tube with the cuff positioned immediately under the vocal cord. In patient 1, the diseased lung remained consolidated after 24 h of differential lung ventilation. In the two other patients, the diseased lungs responded to differential lung ventilation by increased compliance and radiographic increased aeration. Differential ventilation of the lungs with this novel technique is feasible and may increase the likelihood of successful treatment of atelectatic lungs refractory to conventional ventilator strategies.© 2014 The Acta Anaesthesiologica Scandinavica Foundation.
