Preoperative blood inflammation markers to predict nausea after orchiopexy in children

Association of Preoperative Inflammatory Biomarkers With Postoperative Nausea and Vomiting in Children Undergoing Orchiopexy

Observational Diskapi Yildirim Beyazit Education and Research Hospital · NCT07148063

This project will test whether preoperative blood inflammation markers can help predict which children aged 1–8 will have nausea and vomiting after orchiopexy.

What this trial studies

This prospective observational study will enroll children aged 1–8 undergoing elective orchiopexy and record preoperative inflammatory markers including NLR, PLR, SII, MLR, and SIRI. Blood counts will be measured before surgery and patients will be monitored for postoperative nausea and vomiting during the immediate recovery period. Researchers will analyze whether baseline marker levels correlate with PONV incidence while excluding children with active infection, prior nausea/vomiting history, or ASA III+ status. The goal is to see if routine laboratory measures can identify higher-risk children for targeted prophylaxis.

Who should consider this trial

Good fit: Ideal candidates are children aged 1–8 years with ASA physical status I–II who are scheduled for elective orchiopexy and whose parents/guardians can give informed consent.

Not a fit: Children outside the 1–8 year range, those with active infections, ASA III or higher, or a history of prior nausea/vomiting are excluded and unlikely to benefit from these findings.

Why it matters

Potential benefit: If successful, clinicians could use routine preoperative blood counts to identify children at higher risk of PONV and offer targeted anti-nausea prevention.

How similar studies have performed: Previous adult and some pediatric studies have linked inflammatory markers like NLR and PLR to postoperative complications and PONV risk, but applying SII, MLR, and SIRI specifically to young orchiopexy patients is relatively novel.
