41 patients (ASA I-II) were intubated using a new device for blind oral intubation (Augustine Guide). A group of 33 consecutive patients (Mallampati I and II), was studied for routine intubation. Another group of eight patients (Mallampati III and IV) was selected to study the guide in difficult airway management. Intubation was successful in 31 of the 33 normal patients (two patients required a second attempt), and in seven of the eight patients in the difficult intubation group (three patients with two attempts). In the remaining three patients intubation had to be performed by direct laryngoscopy. One patient (Mallampati IV), was intubated by the Augustine guide after three unsuccessful attempts by direct laryngoscopy. The Augustine Guide proved to be helpful to intubating patients with an anterior larynx and receding mandible. However, blind oral intubation attempts required a median duration of 65 s (range 35-90 s). Patients with a low Mallampati score did not benefit from the new device.
