Effect of Dexmedetomidine on Emergence Agitation and Postoperative Behavior Changes in Children

2018年9月5日 更新者:Jin Dong Liu、Xuzhou Medical University

Effect of Single-dose Dexmedetomidine on Emergence Agitation and Postoperative Behavior Changes After Sevoflurane Anesthesia in Children

Emergence agitation (EA) is a dissociated state of consciousness in which the child is inconsolable, irritable, uncooperative, typically thrashing, crying, moaning, or incoherent. Although usually transient, it is not only an extremely distressing event for children, parents, and staff, but may also result in self-injury or the need for restraint. The prevalence in children appears to be between 10% and 80% depending upon the definition and measurement tools used and is more frequently observed in the pre-school age-group. A clear correlation has been found between EA and negative postoperative behavioral changes, including anxiety, eating and sleeping disorders, enuresis, fear of darkness, that may persist for an extended period of time affecting emotional and cognitive development.Currently, numerous interventions have been studied to manage EA after surgery. Among them, dexmedetomidine (DEX) as a kind of highly selective α2 adrenergic receptor agonist has been done to reduce EA in children. Unfortunately, no studies examined posthospitalization negative behaviour changes.

研究概览

详细说明

The high incidence of EA and postoperative behavioural changes has encouraged paediatric anaesthetists and researchers to study methods to improve the perioperative care of children. Dexmedetomidine is a selective alpha-2 receptor agonist with properties that make it attractive to pediatric use. It provides sedation and anxiolysis acting on these receptors in the locus ceruleus of the pons. It also exerts dose-dependent moderate primary analgesic effects through activation of alpha-2 adrenoreceptors in the dorsal spinal horn causing a subsequent decrease in substance P release. The study aims to explore whether a single low-dose dexmedetomidine in the perioperative period has a preventive effect on EA in children, and through short-term and long-term follow-up, to investigate the effect on post-hospitalization behavioural changes.

主要结果指标

结果测量
措施说明
大体时间
Incidence of EA as assessed by the Pediatric Anesthesia Emergence Delirium (PAED) scale
大体时间:within 30 minutes after extubation in the post-anaesthesia care unit
Use the Pediatric Anesthesia Emergence Delirium (PAED) scale to record the incidence of EA.The score ranges from 0 to 20 points. A score of 10 or above is considered as EA.
within 30 minutes after extubation in the post-anaesthesia care unit

次要结果测量

措施说明
大体时间
Pain scores as assessed by the Face, Legs, Activity, Cry, Consolability (FLACC) scale
大体时间:within 30 minutes after extubation in the post-anaesthesia care unit
Use the Face, Legs, Activity, Cry, Consolability (FLACC) scale to record the pain scores. The score ranges from 0 to 10 points. A score of 4 or above is considered as pain.
within 30 minutes after extubation in the post-anaesthesia care unit
Rescue analgesia and sedative drug consumption
大体时间:within 30 minutes after extubation in the post-anaesthesia care unit
Rescue analgesia and sedative drug consumption in the post-anaesthesia care unit

Incidence of adverse events
大体时间:within 30 minutes after extubation in the post-anaesthesia care unit

within 30 minutes after extubation in the post-anaesthesia care unit
Post-hospitalization negative behaviour changes as assessed by the Post Hospitalisation Behaviour Questionnaire (PHBQ) scale
大体时间:1 day, 2 days,30 days post surgery
Use the Post Hospitalisation Behaviour Questionnaire (PHBQ) scale to record the incidence of Post-hospitalization negative behaviour changes.This consists of 27 items describing six subscales: general anxiety, separation anxiety, sleep anxiety, eating disturbances, aggression against authority and apathy/withdrawal.The possible answers were provided on a scale from 1 to 5 ('much less', 'less', 'unchanged', 'more' or 'much more' than before hospitalisation).A score of 0 was awarded if no negative behaviour was reported either before or after surgery.Total score was calculated by adding up all responses.
1 day, 2 days,30 days post surgery
