The purpose of this study was to determine whether a short and simple period of training would increase the speed and accuracy of LMA placement by dental students unfamiliar with airway management. The participants who practiced at least 5 times had a shorter insertion time and superior placement grade. Those who practiced only 5 times had similar insertion grades to those who practiced 10 times.

14 Nov 2009Average (SD) LMA insertion times per student for the nil practice group (group 1), 5 times practice group (group 2), and 10 times practice group (group 3) were 15.8 ± 3.0, 12.0 ± 2.7, and 9.1 ± 1.7 seconds, respectively.
Thirty-five fifth-year dental students from a 6-year, undergraduate dental program who had never seen or used an LMA volunteered for the study. Ethical approval was granted before the study was performed by the University Ethic’s Committee and the university’s president. The participants were classified into 3 groups. The first group (n = 12) received only a demonstration on how to use the LMA (nil practice group). The second group (n = 11) received the demonstration and practiced inserting the LMA 5 times on the adult intubation model manikin (Laerdal, Stavanger, Norway; 5 times practice group). The third group (n = 12) received the demonstration and practiced inserting the LMA 10 times on the manikin (10 times practice group).

12 Nov 2009Any health care professional can be faced with a medical emergency in which the patient may require ventilatory support. One of the most important considerations during resuscitation, as well as in the provision of general anesthesia, is the delivery of oxygen to the lungs. The most common indication for airway intervention is unconsciousness, during which the airway is frequently obstructed by the base of the tongue falling into the posterior oropharynx and hypopharynx. The main problems associated with difficult airway include brain injury, myocardial injury, airway trauma, and death.

The DP is not recommended by the manufacturer for use in children younger than 12 years, since the clinical trials have not been performed for children. The DP contained 46.1 mg of lidocaine, which is the equivalent to the amount of lidocaine found in 1.28 cartridges of 2% lidocaine with 1:100,000 epinephrine. The peak lidocaine plasma level for a 15-minute application period is 16-22 ng/mL, which is about one tenth of the peak lidocaine plasma level for an injection of 1 carpule of 2% lidocaine with 1:100,000 epinephrine. Therefore, the DP was determined to have very low toxicity. Based on these pharmacologic data, it was determined that the DP would be safe to use in children.

10 Nov 2009Twenty-eight subjects were enrolled (12 girls and 16 boys). The subjects ranged in age from 6.4 to 17.4 years, with a mean age of 11.3 years (SD = 3.5 years). Nineteen of the subjects had sealants placed on 2 teeth. Nine subjects had sealants placed on 4 teeth.
All subjects were patients of record at the University of Minnesota School of Dentistry Pediatric Dental Clinic. The parent signed a consent form, which described the procedure, for each subject. Subjects who were 8 years and older had to sign a child’s assent form, which described the procedure.
