identifying the most common encountered complica- tions as well as possible contributing factors to be of great importance. Methods: A retrospective cohort study was performed using a sample of patients 13 years or younger treated at NYU College of Dentistry and Bellevue Hospital Center from July 2014 to July 2017 under outpatient ambulatory anesthesia. A total of 361 pediatric patients meeting the above criteria were identified, and all charts were re- viewed for complications encountered pre-operatively, intra-operatively, and/or post-operatively. Additional information collected included age, gender, ASA classification, weight of the patient, reported NPO time for both solids and liquids, procedure performed, length of procedure time, sedative agent(s) and dosages, recorded adverse events, reversal agents, or other IV agents utilized to counteract adverse effects, concurrent opioid use, and sedation failure. Results: Adverse events recognized to have occurred based on the data collection included the incidence of post-operative nausea/vomiting, suspected laryngo- spasm, stridor, airway obstruction requiring escalated management (i.e., jaw thrust or oropharyngeal airway), excessive secretions, and delirium. No instances of death, cardiac arrest, aspiration with subsequent pulmonary re- percussions, or need for cardiopulmonary resuscitation were encountered throughout the 3-year period. Seda- tion failure was accounted for and identified as any pro- cedure unable to be completed under IV anesthesia due to experiencing 1 or more of the complications listed above. Conclusion: While this study suggests that serious adverse events are reasonably rare within the pediatric population, minor adverse events with the potential for escalation to detrimental outcomes can be relatively com- mon. Consequently, identification and proper manage- ment of such complications, as well as a founded understanding of the potential exacerbation of these complications, is of utmost importance when adminis- tering pediatric outpatient ambulatory anesthesia. Simi- larly, it should be noted that appropriate patient selection and a low threshold for case rejection based on ASA status and case complexity likely contributed to our low incidence of adverse events. It is therefore highly recommended that this exclusionary outlook be a heavily considered factor when selecting ideal candidates to undergo such procedures. References: 1.

Miller: Assistant Professor - University of Texas Health Sciences Center San Antonio, B. A. Golden, R. L. Ruiz Statement of the Problem: Aplasia cutis congenital of the scalp is a rare congenital malformation character- ized by the focal absence of skin at birth. Its presentation varies widely and involves the epidermis, dermis, or un- derlying structures, such as bone or dura. They present in various sizes and severity. It has been difficult to find supportive protocols for wound care in treating these pa- tients. We suggest a conservative approach with wound care in lieu of surgery. Materials and Methods: Our protocol is based on the treatment of a newborn we were consulted to surgically reconstruct by the neonatal intensive care unit with an initial defect covering most of the posterior parietal scalp. This protocol was developed by our Craniomaxillofacial Surgery Team with the assistance of the wound care ser- vice. To prevent infection and promote the resolution of the defect, we describe a very specific regimen to keep the wound moist as well as covered for bacte- rial ingrowth. Conclusion: Surgical treatment is often preferred for larger defects associated with aplasia cutis conge- nita, but we were able to show complete resolution of the defect using conservative therapy by 5 months of age.
