Parental presence and intranasal dexmedetomidine for the prevention of anxiety during anesthesia induction in children undergoing tonsillectomy and/or adenoidectomy surgery: A randomized controlled trial

Abstract

Background: During the perioperative period of pediatric surgery, it is extremely stressful for children and parents to enter the operating room and receive the anesthesia induction. This study was designed to evaluate the perioperative outcomes with parental presence at induction of anesthesia (PPIA), intranasal dexmedetomidine, and combined use of PPIA and intranasal dexmedetomidine.Methods: In this prospective study, 124 children were randomly divided into four groups: control (no parental presence or intranasal dexmedetomidine), PPIA (parental presence), DEX (intranasal dexmedetomidine (1.0 μg/kg)), and PPIA + DEX (parental presence and intranasal dexmedetomidine (1.0 μg/kg)). The anxiety of children was mainly evaluated by the modified Yale Preoperative Anxiety Scale-Short Form (mYPAS-SF). Secondary evaluation methods were, for example, the Induction Compliance Checklist (ICC), the Pediatric Anesthesia Emergence Delirium Scale (PAED), the COMFORT Behavior Scale (COMFORT-B Scale), the State-Trait Anxiety Inventory (STAI), and the Visual Analog Scale (VAS).Results: Children in the PPIA + DEX group exhibited significantly lower mYPAS-SF and ICC scores compared with all three other groups (p < 0.001), and children in that group exhibited significantly lower mYPAS-SF and ICC scores compared with the PPIA and DEX groups (p < 0.05). The children’s PAED scores in the PPIA, DEX, and PPIA + DEX groups were significantly lower than the control group (p < 0.001).The STAI-S scores of the PPIA, DEX, and PPIA + DEX groups were significantly lower than the score of the control group (p < 0.001). The VAS scores of the PPIA, DEX, and PPIA + DEX groups were significantly higher than that of the control group (p < 0.001), while the score of the PPIA + DEX group was significantly higher than those of the PPIA and DEX groups (p < 0.05).Conclusion: The combined use of PPIA and intranasal dexmedetomidine is more effective than PPIA or intranasal dexmedetomidine for alleviating the preoperative anxiety of children, improving children’s induction compliance and parental satisfaction.
