Inflammation markers and postoperative delirium after pediatric circumcision

Effect of Preoperative Inflammatory Biomarkers on Postoperative Delirium in Children Undergoing Circumcision

Observational Ankara Etlik City Hospital · NCT07323485

This project will test whether common blood inflammation markers taken before surgery can help predict which children aged 2 to 12 develop delirium right after circumcision under general anesthesia.

What this trial studies

This prospective observational study will enroll children aged 2–12 undergoing elective circumcision under general anesthesia. Preoperative inflammatory biomarkers derived from routine complete blood count parameters (NLR, PLR, MLR, SII, SIRI) will be measured. Postoperative emergence delirium will be recorded in the post-anesthesia care unit using the Pediatric Anesthesia Emergence Delirium (PAED) scale, and associations between biomarker levels and delirium occurrence and severity will be analyzed. Children with neurological or psychiatric diagnoses, hematologic/hormonal disorders, ASA III–IV status, or incomplete preoperative labs will be excluded.

Who should consider this trial

Good fit: Ideal candidates are children aged 2–12 scheduled for elective circumcision under general anesthesia with ASA physical status I–II whose parents provide consent and who can give age-appropriate assent.

Not a fit: Children outside the 2–12 age range, those with neurological/psychiatric or hematologic disorders, ASA III–IV patients, emergency procedures, or those lacking preoperative laboratory data are unlikely to benefit from this protocol.

Why it matters

Potential benefit: If successful, simple preoperative blood-count markers could help identify children at higher risk for emergence delirium so clinicians can plan closer monitoring or preventive steps.

How similar studies have performed: Adult studies have reported links between preoperative inflammatory markers and postoperative delirium, but comparable pediatric evidence is limited and the approach is relatively untested in children.

Eligibility criteria

Inclusion Criteria:

* Children aged 2-12 years.
* Patients scheduled to undergo elective circumcision under general anesthesia.
* Patients classified as ASA physical status I-II.
* Patients whose parents or legal guardians provide written informed consent, and whose age-appropriate verbal assent is obtained from the child.
* Patients in whom anesthesia and surgical procedures are performed according to standard institutional protocols throughout the study period.

Exclusion Criteria:

* Children with a history of neurological or psychiatric disorders (e.g., epilepsy, developmental delay, autism spectrum disorder, anxiety disorders).
* Patients classified as ASA physical status III-IV.
* Patients with incomplete preoperative laboratory data or with hematological or hormonal disorders that may affect inflammatory parameters.
* Patients who develop excessive sedation after premedication or whose preoperative assessment cannot be completed.
* Patients with protocol deviations during surgery or anesthesia (e.g., additional medications, prolonged surgical duration, or changes in procedure due to complications).
* Patients whose parents or legal guardians do not provide consent or who decline participation.
