Is inpatient monitoring necessary in pediatric patients with comorbidities following routine dental procedures? A retrospective analysis.

purposeChildren and young adults with severe pre-existing conditions frequently require dental treatment under general anesthesia (GA) and are commonly scheduled for postoperative inpatient surveillance due to presumed elevated anesthetic or surgical risks. Although this approach prioritizes safety, it may contribute to prolonged or unnecessary hospitalization, increased healthcare costs, and potential psychological burden, particularly in patients with neurodevelopmental or congenital disorders. In light of the reportedly low incidence of severe complications following dental treatment under GA, this study aims to evaluate the necessity of routine inpatient admission in pediatric patients (< 18 years of age) with comorbidities and to assess the frequency and severity of perioperative complications.

methodsAll pediatric patients with pre-existing conditions who underwent planned inpatient surgical dental treatment under GA at the Department of Oral and Maxillofacial Surgery at Hannover Medical School between 2014 and 2025 were included. The indications for inpatient treatment, anesthesiological parameters such as the American Society of Anesthesiologists (ASA) classification, and severe perioperative complications (corresponding to grade ≥ 2 of the Clavien-Dindo classification) were analyzed. It was assessed whether the ASA classification or the type of pre-existing condition significantly influenced the occurrence of perioperative complications.

resultsA total of 199 patients were analyzed. Patients who underwent surgery were mainly categorized as ASA II (n = 80, 40.2%) and III (n = 102, 51.3%), and mostly presented with cardiovascular (n = 68, 34.2%) or hematological/oncological preconditions (n = 47, 23.6%). Perioperative complications occurred in 8 cases (4.2%); of those, 6 were intraoperative (3.1%), and 2 were postoperative (1.0%). The probability of perioperative complications did not correlate with ASA classification or pre-existing conditions (p [Fisher] = 0.166, and p [Fisher] = 0.571, respectively). Age significantly influenced the probability of complications (U = 451.00, p = 0.050), indicating that older patients were more likely to experience complications than younger patients.

conclusionAs postoperative complications occur very rarely, even in patients with pre-existing conditions, inpatient surveillance should warrant thoughtful consideration to liberate hospital capacities. Interdisciplinary pre-, intra-, and postoperative assessment of the need for inpatient surveillance should ensure patient safety and provide further insights into risk factors for peri- and especially postoperative complications. The authors recommend validating risk scores and algorithms for decision-making regarding inpatient surveillance.
