- Background: One-lung ventilation (OLV) is necessary for selected surgical settings and medical conditions. Different methods have been described and used to isolate 1 lung, including the double-lumen endotracheal tube (DLT) and a variety of bronchial blockers (BBs). This selection is often based on the preferences and experiences of the anesthesiologist and surgeon. Complications associated with OLV isolation tubes have been previously described, but complications specifically associated with the Cohen BB (CBB) (Cook Medical, Bloomington, IN) have not been investigated. The purpose of this retrospective review was to determine the incidence of vocal cord injury, tracheobronchial injury, and hoarseness in adult patients who underwent OLV with the CBB.; Methods: We reviewed electronic anesthesia records, operative dictation, and inpatient progress notes to collect information about vocal cord injury, bronchial injury, hoarseness, and sore throat for adults who underwent surgical and diagnostic procedures requiring OLV. Secondary endpoints were types of surgical procedures, degree of difficulty with orotracheal intubation, ability of the patient to tolerate extubation in the operating room, and whether the thoracic surgeon deemed the lung separation adequate. P<0.05 was considered significant.; Results: Of 130 patients, 113 underwent OLV with a CBB, and 17 patients underwent OLV with a DLT. The thoracic surgeon deemed the lung isolation adequate in all cases. Airway injury occurred in 2 patients with a CBB and none with a DLT (P = 0.86). Both airway injuries were attributed to surgical technique. Two cases of postoperative hoarseness occurred in the CBB group (P = 0.86). One injury was attributed to vagus nerve transection, and the other injury was diagnosed as vocal cord paralysis of unknown etiology. In 1 case, orotracheal intubation with a DLT was unsuccessful because of intubation difficulty and required conversion to a regular endotracheal tube and CBB for successful lung isolation.; Conclusion: This study demonstrates that the use of CBB can be successful in a wide variety of thoracic operations, has minimal complications, eliminates the need for tracheal tube exchange when postoperative mechanical ventilation is required, and effectively isolates the lungs of critically ill patients.
