Intubation for pediatric patients is frequently performed with an uncuffed endotracheal tube (ETT), which may result in an incomplete tracheal seal, resulting in gas leakage (leak). The purpose of this study was to assess the effect of (1) mouth opening and (2) throat pack placement in sealing and/or minimizing this leak to an acceptable level while providing adequate tidal volumes in mechanically ventilated patients. This prospective study of 2- to 6-year-olds undergoing general anesthesia with nasal intubation for dental procedures in the New York University-Lutheran Medical Center operating room was conducted between March 2015 and October 2015. Three sequential tidal volume (V_T) measurements were recorded: postintubation with the neck extended, with mouth opened, and after throat pack placement. Twenty-five subjects were included in the analyses. For subjects in whom no leak was detected, only throat pack placement statistically improved V_T. This is in marked contrast to numerically large, statistically significant effects, relative to baseline, for mouth opening (±23.2 mL, p < .009, 21% increase from baseline) and throat pack placement (±46 mL, p < .009, 41% increase from baseline) when a leak was detected. In children 2-6 years of age, nasal intubation with uncuffed ETTs that have incomplete tracheal seal have improved V_T with mouth opening and throat pack placement. This finding suggests that the intubation procedure is a process that extends through positioning, mouth opening, and throat pack placement.

During routine deep sedation for endodontic therapy, a dentist-anesthesiologist observed premature ventricular contractions (PVCs) on a 62-yr-old woman's electrocardiogram (EKG) tracing. The dentist was able to complete the root canal procedure under intravenous (i.v.) sedation without any problems. The dentist-anesthesiologist referred the patient for medical evaluation. She was found to be free from ischemic cardiac disease with normal ventricular function. The patient was cleared to continue her dental treatment with deep sedation. She subsequently continued to undergo dental treatment with deep intravenous sedation without incident, although her EKG exhibited frequent PVCs, up to 20 per minute, including couplets and episodes of trigeminy. This article will review indications for medical intervention, antiarrhythmic medications, and anesthetic interventions for perioperative PVCs

According to the American Heart Association, 'Successful completion of an ACLS course means in accordance with the cognitive and performance standards of the American Heart Association. It does not warrant performance, nor does it, per se, qualify or authorize a person to perform any procedure. It in no way related to licensure, which is a function of the appropriate legislative, health or educational authority.' The same can be said for BLS; however, with the recent revisions in ECC programs, even this disclaimer has been eliminated from the most recent textbooks in BLS and ACLS. This is in keeping with '...the American Heart Association's reaffirmation of its role as an educational resource rather than as a certifying agency.' Lay public course participants in BLS (which technically includes dentists) will now receive course participation cards. Health care provider course participants will continue to receive 'course completion cards' if all criteria have been satisfied by the student. The trend is to categorize what was previously termed testing as evaluation. Certification has become a thing of the past. It is unclear at this time what the impact this policy change will have on agencies who rely upon documentation from the American Heart Association to satisfy requirements that have been imposed upon dentists and other health professionals for initial licensure and relicensure. Semantics aside, one thing that remains clear is the expectation of the dentist with regards to emergency management. Expertise (for lack of a better term) in specific aspects of ECC remains a standard. For all dentists, expertise in BLS is that standard. For dentists administering deep sedation and general anesthesia, expertise in ACLS is the community standard. Although there is some ambiguity for those dentists administering conscious sedation, at the very least, they should have expertise in BLS. In addition, they are strongly encouraged to have expertise in ACLS, particularly because the limited hours of training in conscious sedation provide less medical background than is acquired during training in deep sedation and general anesthesia. In addition, the dentist is ultimately responsible for the demeanor of his or her office and staff. In the prehospital dental office setting, the matter of converting a dental office team geared to efficient delivery of dental procedures, into a team primed to perform emergency cardiac care seems daunting. This is especially so if the dentist has little undergraduate or clinical preparation for managing life-threatening emergencies. Therefore, an emergency management plan (with oversight for its implementation by the dentist) is of paramount importance
