[Placement of a bronchial blocker through the I-gel supraglottic airway device for single-lung ventilation: preliminary study].

To describe the use of the I-gel supraglottic airway device when placing a bronchial blocker for single-lung ventilation, as applied in a preliminary study to explore the feasibility of adopting the technique with appropriate, selected patients undergoing certain thoracic surgery procedures. We used the technique for single-lung ventilation in 25 patients who required isolation of a lung for a variety of thoracic surgical procedures. A bronchial blocker was placed under direct visualization through a fiberoptic bronchoscope and the I-gel supraglottic device. The I-gel mask allowed us to establish a reliable, safe seal of the airway. For an anesthetist with sufficient experience in managing a flexible fiberoptic bronchoscope, it was possible to carry out all procedures without remarkable anesthetic or surgical events. Single-lung ventilation achieved by introducing a bronchial blocker through the I-gel supraglottic device can facilitate safe, effective management of selected patients who must undergo certain thoracic surgery procedures.
