The relationship of placement accuracy and insertion times for the laryngeal mask airway to the training of inexperienced dental students.

Any health care professional can be faced with a medical emergency in which the patient needs ventilatory support. Bag-valve-mask ventilation with the assistance of an oropharyngeal airway that uses 100% oxygen is currently the preferred method for artificial ventilation. This procedure is generally performed ineffectively by most dentists inexperienced in airway management. We examined whether a short and simple period of training by dental students inexperienced in airway management would increase the speed and accuracy of the placement of the laryngeal mask airway (LMA), which may be a superior airway device to the bag-valve-mask and oropharyngeal airway. Thirty-five dental students inexperienced in airway management were divided into 3 groups. The first group received only a demonstration on how to use the LMA. The second and third groups received the demonstration plus practiced inserting the LMA 5 and 10 times, respectively. A dental anesthesiologist graded the placement of the LMA with a tracheobroncho-fiberscope (fiberoptic bronchoscope). Those who practiced inserting the LMA 5 times faired better than those who received no training; however, those who practiced 10 times did not do any better than the second group. The LMA can be inserted rapidly and effectively by dentists inexperienced in airway management after a short period of simple training that may be critical when personnel experienced in intubation are not readily available.
