Abstract:Objective: To study the incidence of post-discharge adverse events occurring after dental treatment under general anesthesia in pediatric patients aged 1-6 years and compare their distribution differences in different age groups. Methods: A total of 110 children, including 72 boys (65.5%) and 38 girls (34.5%), American Society Anesthesiologists physical statusⅠorⅡ, who received oral treatment under general anesthesia in the Stomatological Clinic of The First Affiliated Hospital of Zhengzhou University from January 2019 to February 2020 were collected. According to the age of the children, they were divided into two groups: infant group (1-3 years, 58 cases) and preschool group (4-6 years, 52 cases). The telephone follow-up records of first 24 hours after surgery were inquired to summarize the incidence of adverse events, including crying, toothache, oral discomfort, emotional instability, fever, drowsiness, bleeding gums, red lips, salivation, mouth breathing and whether the children had any memory of the dental experience, etc, and their distribution differences in different age groups were compared. Results: In this study, 62.7%of children had one or more adverse events reported. The incidence of adverse events in the infant group and preschool group were 55.2%and 71.1%, respectively (P>0.05). Crying (41.3%) and bad memory of dental visits (40.4%) were the highest incidence of adverse events in the infant group and preschool group, respectively. The incidence of memory, emotional instability and irritability and toothache in the infant group were 13.8%, 6.9%and 8.6%, respectively, which were all lower than those in the preschool group (40.4%, 21.2%, 23.1%, respectively), with statistical differences (P<0.05). The number of treated teeth, the number of extracted teeth, and the number of endodontic treatments in the infant group were (11.5±2.9), (1.6±1.4) and (5.3±3.3), respectively, which were significantly lower than those in the preschool group [(13.3±3.5), (3.2±1.1) and (7.5±4.1), respectively] (P<0.05). The number of total coronary treatments in the two groups was (3.5±2.3) and (4.6±3.7), respectively, without significant difference (P>0.05). Conclusion: In oral treatment under general anesthesia, the effect of intraoperative sedation and analgesia is positive. However, the incidence of discomforts occurring after general anesthesia, such as crying, bad memory of medical experience and toothache, is relatively high, and necessary attention should be given. For infants and young children, the comfort of their crying should be strengthened. Due to the large number of teeth and complex dental conditions in preschool children, the probability of adverse events is higher, and the effect of perioperative forgetting and analgesia should be strengthened.
