T he face mask, laryngeal mask, and the Combitube (Tyco Healthcare/Sheridan, Argyle, NY) are devices commonly used to ventilate the lungs of nonintubated patients (1,2), but some disadvantages may result in inadvertent ventilation-associated complications. For example, the face mask is associated with large dead space ventilation, leakage, and gastric inflation (3). In contrast, the laryngeal mask is an alternative airway adjunct that is simple to use, resulting in both minimal dead space ventilation and gastric inflation (4,5). Nevertheless, a possible limiting feature of the laryngeal mask may be the risk of aspirating gastric contents (6) because fiberoptic studies have found 6%–9% visualization of the esophagus (7,8). Although the Combitube was developed as an alternative to endotracheal intubation to secure the airway in an emergency setting, its complex structure requires extensive instruction and training to ensure correct placement within an acceptable time (9). The purpose of this study was to assess whether the newly developed Laryngeal Tube (VBM Medizintechnik GmbH, Sulz, Germany), somewhat a single-lumen, shortened Combitube, can provide sufficient ventilation and adequate oxygenation in patients undergoing routine induction of anesthesia.
