Postoperative delirium may occur in children after general anesthesia, even following short procedures such as circumcision. Preoperative systemic inflammation has been associated with postoperative delirium in adults, but data in pediatric patients are limited. This prospective observational study aims to evaluate the association between preoperative inflammatory biomarkers and postoperative delirium in children aged 2-12 years undergoing elective circumcision under general anesthesia. Inflammatory biomarkers derived from routine complete blood count parameters, including NLR, PLR, MLR, SII, and SIRI, will be analyzed. Postoperative delirium will be assessed using the Pediatric Anesthesia Emergence Delirium (PAED) scale in the post-anesthesia care unit. The relationship between inflammatory biomarkers and delirium development and severity will be evaluated. This study seeks to identify simple preoperative markers that may help predict postoperative delirium risk in pediatric patients.

AI-rewrites the medical criteria so a patient or caregiver can understand them. Always confirm with the trial site.
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.
Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
