Abstract
Objective: To investigate the effectiveness of child-centered playful companionship and sedative medication in alleviating preoperative anxiety in preschool children. Methods: A retrospective analysis was conducted on 3 825 preschool children (3-6 years) who underwent elective surgery at Shanghai Children's Medical Center from April 2021 to March 2022. The children were divided into three groups based on the preoperative anxiolytic intervention: child-centered playful companionship group (n=2 198), pharmacological sedation group (n=1 281), and no intervention group (n=346). The pharmacological sedation group received intranasal dexmedetomidine at 2 μg/kg or oral midazolam syrup at 0.5 mg/kg. The child-centered playful companionship group received care from certified preoperative sedation nurses using a child-centered playful nursing model. The no intervention group did not receive any anti-anxiety measures due to various subjective and objective reasons. Preoperative separation anxiety scores (PSAS), sedation medication usage, and Ramsay sedation scores were recorded for all children. The primary outcome was the success rate of separation based on PSAS scores across different anxiolytic intervention groups, while the secondary outcome was the Ramsay sedation score. Results: The child-centered playful companionship group included 1 462 boys and 736 girls, with a median age [M (Q1, Q3)]of 59 (49, 69) months. The pharmacological sedation group included 824 boys and 457 girls, with a median age of 52 (42, 61) months; and the no intervention group included 212 boys and 134 girls, with a median age of 57 (48, 69) months. The success rate of separation in the child-centered playful companionship group was 95.6% (2 102/2 198), and in the pharmacological sedation group was 93.8% (1 202/1 281), both significantly higher than the 43.6% (151/346) of the no intervention group (all P<0.05). Among the 1 281 children in the pharmacological sedation group, 785 received oral midazolam and 496 received intranasal dexmedetomidine. Compared to the intranasal dexmedetomidine group, the oral midazolam group was younger, had a lower body weight and a higher proportion of American Society of Anesthesiologists (ASA) class Ⅲ (all P<0.05). The success rate of separation was 93.4% (733/785) in the oral midazolam group and 94.6% (469/496) in the intranasal dexmedetomidine group, with no statistically significant difference (P=0.392). The Ramsay sedation score was 2 (2, 2) in the intranasal dexmedetomidine group, better than the 2 (2, 2) of the oral midazolam group (P=0.024). Conclusion: Both child-centered playful companionship and pharmacological sedation effectively alleviate preoperative anxiety in preschool children.
