RESUMO
ObjectiveFor children with dental fear who refuse to take oral medicine, the advantage of nasal administration remains undetermined. The purpose of the study was to compare the effectiveness of oral and intranasal midazolam in children with dental fear by evaluating their physiological and behavioral responses.MethodsFrom January 2018 to May 2019, 112 children were selected from the Department of Stomatology, the First Affiliated Hospital of Baotou Medical College, Inner Mongolia University of science and technology. Children were randomly divided into two groups: the oral group (oral midazolam) and the nasal group (nasal spray was used to spray midazolam into the nose), with 56 cases in each group. The sleep status, crying status, movement status and behavior scores were recorded at the beginning of administration, binding plate, local anesthesia, 5min, 10min, 15min, 20min and 25min respectively. The scores of Ramsay scale and behavior were compared between the two groups.ResultsThere was no significant difference in sleep score between oral group (2.01±0.11) and nasal group (1.98±0.24) (P>0.05). The crying score [(2.0±0.3)], movement score [(2.1±0.1)], and behavior score [(2.0±0.5)] in the nasal group were significantly higher than those in the oral group [(1.3±0.1), (1.3±0.3), (1.4±0.2)], the difference was statistically significant (P0.05). ConclusionOral midazolam and intranasal midazolam have similar sedative effects for relieving children′s anxiety. However, the sedation effect was faster of oral midazolam, which can provide guidance for children in clinical oral medicine.
