Pre-surgery sleep program to reduce delirium after congenital heart surgery in infants and toddlers

The Impact of Cognitive Behavioral Intervention On Postoperative Delirium In School-aged Children With Sleep Disorder Undergoing Congenital Heart Surgery: A Multicenter, Randomized Controlled Clinical Trial

Not applicable Interventional Chinese Academy of Medical Sciences, Fuwai Hospital · NCT06879431

This study will try a short cognitive-behavioral sleep program before elective congenital heart surgery to see if it lowers postoperative delirium in infants and toddlers (0–36 months) with sleep problems.

What this trial studies

This is a multicenter, randomized controlled trial enrolling children aged 0–36 months with sleep disorders (CSHQ score >48) who are scheduled for elective corrective congenital heart surgery under cardiopulmonary bypass. After screening and consent, participants are randomized 1:1 by center to receive either a brief intensive preoperative cognitive-behavioral sleep intervention delivered daily 7–14 days before surgery via a WeChat mini-program with parent support, or usual care with no added sleep intervention. The primary outcome is the incidence of postoperative delirium and other adverse postoperative outcomes. The trial is conducted at several major cardiac and pediatric centers in China, with standardized assessments and follow-up around the surgical episode.

Who should consider this trial

Good fit: Infants and toddlers (0–36 months) with congenital heart defects scheduled for elective corrective surgery under cardiopulmonary bypass who have sleep problems (CSHQ score >48) and meet other inclusion/exclusion criteria are ideal candidates.

Not a fit: Children requiring emergency surgery, with high surgical risk (RACHS-1 ≥4), preexisting neurodevelopmental or psychiatric disorders, severe organ dysfunction, or current sleep medication use are unlikely to benefit or be eligible.

Why it matters

Potential benefit: If successful, the intervention could reduce postoperative delirium and improve recovery after congenital heart surgery for affected infants and toddlers.

How similar studies have performed: Behavioral sleep therapies have shown benefit for pediatric sleep problems, but using a brief preoperative cognitive-behavioral program specifically to prevent postoperative delirium in infants with CHD is largely novel and not yet well established.
