Abstract

In this two-part study we attempted to find a method for preventing lip laceration during tracheal intubation. First, we retrospectively investigated the frequency and location of lip lacerations that occurred during tracheal intubation. This survey revealed that 145 patients (4.9%) out of 2, 963 experienced some form of lip injury during intubation. Of these, lacerations occurred on the top lip in 127 cases (87.6%). These finding suggested that the application of a mouthpiece and a mouth gag could prevent the injury to the top lip.In the second part of the study, we recorded the incidence of lip laceration in 100 patients who wore a bite prevention apparatus during intubation and in 100 patients who underwent intubation without such a device. Lip laceration occurred in 12% of the group with the apparatus and 45% of the group without the protective lip device. This apparatus is effective in preventing lip laceration during tracheal intubation.
