About

This is a multicenter, randomized, controlled clinical trial aimed to determine whether preoperative sleep interventions could reduce the incidence of adverse outcomes, such as postoperative delirium, in sleep-disordered school-aged children undergoing congenital heart surgery. The study will include infants and toddlers undergoing elective cardiac surgery with sleep disorders, assessed by the Children's Sleep Habits Questionnaire (CSHQ). All participants will be randomly assigned to the intervention group and Controll group in a 1:1 ratio. The intervention group received a short intensive cognitive-behavioral intervention 7-14 days before surgery, and no intervention was imposed on the control group. The results of this study will provide suggestions for the prevention of delirium after cardiac surgery.

Full description

The study will be carried out in Fuwai Hospital, Chinese Academy of Medical Sciences, Anzhen Hospital Affiliated to Capital Medical University, Fuwai Central China Cardiovascular Hospital, Fuwai Cardiovascular Hospital of Yunnan Province, and Children's Hospital Affiliated to Capital Institute of Pediatrics.

The research process is as follows: Conduct a routine assessment of sleep disorders for the children visiting the outpatient clinic. The guardians fill out the online Children's Sleep Habits Questionnaire. Fully inform the children with sleep disorders and their guardians of all the contents and procedures of this trial. After obtaining informed consent and signing the informed consent form, conduct a further assessment on the children to determine whether they meet the inclusion and exclusion criteria. All enrolled children and their guardians will receive preoperative education for congenital heart disease in the outpatient clinic. After stratification by research center, the random block is set to 4 - 6, the R will be used to randomly assign subjects to the experimental group and the control group at a 1:1 ratio. After randomization, the parents of children in the experimental group register for a WeChat mini-program, and the children receive cognitive-behavioral interventions every day before surgery. Guardians need to strictly implement and cooperate with researchers through phone calls (during the waiting period for admission) or face-to-face communication (during the preoperative hospitalization period). The control group does not receive any intervention and follows routine clinical practice. To better control the quality of interventions for children aged 6 - 12 in the experimental group, the daily implementation status of parents is counted for the degree of implementation (0 - 100%) in the WeChat mini-program. Guardians record the children's daily sleep diaries (online questionnaires) before surgery. The day before surgery, parents fill out the online Children's Sleep Habits Questionnaire again and compare the scores with the baseline scores. After admission, children wear actigraphs until the day of surgery and until discharge after surgery to automatically record sleep-related information. After the children are enrolled in the study, relevant researchers will supervise the implementation of cognitive-behavioral interventions for the children once a day before surgery to ensure that the actigraph device functions properly during hospitalization and remind guardians to record electronic sleep diaries until the night before surgery. Follow-up will be conducted within 7 days after surgery or before discharge to evaluate outcomes such as delirium and pain. The primary outcome is the incidence of postoperative delirium, and secondary outcomes include postoperative sleep quality, pain score, perioperative organ injury (including AKI, acute lung injury, and postoperative liver dysfunction), clinical recovery and prognosis.
