Preoperative Assessment for Children Requiring Dental Treatment Under General Anesthesia

Abstract

Objective. This study aimed to describe children <6 years requiring general anesthesia for dental treatment and factors associated with a change in medical management prior to surgery. Study design. This case series reviewed the past medical history and preoperative assessment of patients referred for dental preoperative evaluations at a single institution (2005-2008). A “deflection” was defined as a recommendation to change preoperative or operative care based on the preoperative assessment. The sample was analyzed using descriptive, bivariate, and multivariate analyses. Results. Of 648 subjects (aged 9 months to 6 years, mean 3.9 years), 63% had a past medical history abnormality and 38% had previous surgery. In total, 14% were deflected, most commonly because of the addition of infective endocarditis prophylaxis (29%). A history of coagulation disorder had the strongest association with deflection ( P < .0001, odds ratio = 10.0, 95% confidence interval = 4.6-22.1), followed by cardiac anomalies. Conclusion. Preoperative assessments for pediatric dental treatment frequently identify medical problems resulting in treatment plan alterations.
