Clinical Usefulness of Proseal Laryngeal Mask Airway for Anesthesia during Dental Procedures in Children

Although the Proseal laryngeal mask airway (PLMA) has been widely used in anesthesia, little is known about its clinical effectiveness during dental procedures. We describe the clinical feasibility of the PLMA for managing airways in the field of pediatric dentistry. .Study design: We reviewed the medical records of children who underwent airway management with the use of the PLMA from January 2011 to December 2012 at an outpatient facility at Seoul National Dental University Hospital. Results: During the study period, the airways of 19 children were managed with the PLMA for dental procedures. During its placement, blood pressure and heart rate were stably maintained. There were no interruptions of the dental procedures. None of the children experienced oxygen desaturation or ventilation difficulty. In one patient, the PLMA was dislodged for a short time, but the problem was easily solved with repositioning. After transferring to the post-anesthetic care unit, there were no incidences of oxygen desaturation or vomiting. All of the children were discharged from the hospital without complications. Conclusion: The PLMA can be successfully used in airway management during dental treatment in children.
