Surveyed were 133 directors of training programs in anesthesiology. The directors reported an average incidence of 1:1,000 dental injuries during or after 1,135,212 tracheal intubations in 1 year. A well-documented dental evaluation before delivery of anesthetics and appropriate precautions and protective devices during intubation will prevent most dental trauma related to the delivery of general anesthetics. Also, early use of dental and risk management services often will ensure timely resolution of such problems.

Comparative Study
Development and severity of palatal grooves in orally intubated newborns. Effect of 'soft' endotracheal tubes.
A prospective, blinded study of neonates orally intubated with either standard or "soft" endotracheal tubes included 57 infants in the standard "hard" tube group and 46 infants in the soft tube group. Infants were further divided by birth weights above and below 1,000 g. ⋯ Neither the incidence nor the severity of palatal groove formation was influenced by the use of the soft tube. However, in three cases the soft tube had to be abandoned due to technical difficulties with intubation.

Airway control in patients with suspected laryngotracheal injury following blunt trauma is a challenging problem. Tracheostomy remains the treatment of choice in most instances. This report describes a patient with a laryngotracheal injury in whom initial airway control was achieved using orotracheal intubation. The indications for this method are discussed, and an approach to initial airway management in these injuries is outlined.

To determine the optimal interval between the administration of the priming dose and the intubating dose, atracurium was given to 44 patients either in a single dose of 0.5 mg X kg-1 or in an initial dose of 0.06 mg X kg-1 followed two, three or five minutes later with 0.44 mg X kg-1. When atracurium was given as a single bolus of 0.5 mg X kg-1 the time to 100 per cent twitch suppression (onset time) was 90.9 +/- 36 (mean +/- SD) seconds. When the priming interval was two minutes, the onset time of the intubating dose was 76.6 +/- 42.2 seconds (p = NS). ⋯ Waiting for five minutes after the administration of the priming dose did not improve the intubating conditions. It is concluded that three minutes appears to be the optimal time interval for the administration of atracurium in divided doses. When a priming dose of atracurium is given three minutes before the intubating dose, it can provide an alternative to succinylcholine for rapid endotracheal intubation.
