Investigating copeptin levels in children after neurosurgery for diabetes insipidus

A Study on the Trend of Serum Copeptin Levels and Its Clinical Value for Postoperative Central Diabetes Insipidus in Pediatric Patients After Neurosurgical Intervention in Intensive Care Unit

Observational Children's Hospital of Fudan University · NCT06742060

This study looks at how copeptin levels change in children after brain surgery to see if it can help predict who will develop diabetes insipidus.

What this trial studies

This observational study aims to explore the trend of serum copeptin levels in pediatric patients following neurosurgical interventions. It focuses on comparing copeptin levels in children who develop transient or permanent central diabetes insipidus (CDI) against those who do not. Blood samples will be collected at various time points post-surgery to assess the relationship between copeptin levels and the occurrence of CDI. The study seeks to establish optimal detection times and cutoff values for copeptin in predicting postoperative CDI.

Who should consider this trial

Good fit: Ideal candidates include children aged 29 days to under 18 years who have undergone neurosurgical intervention.

Not a fit: Patients with pre-existing diabetes insipidus or structural diseases of the genitourinary system may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide a reliable diagnostic tool for predicting central diabetes insipidus in pediatric patients after neurosurgery.

How similar studies have performed: While international studies have explored copeptin's clinical applications in adults, this specific approach in pediatric patients after neurosurgery is novel and has not been extensively tested.
