Using Peripheral Perfusion Index to Predict Caudal Block Success in Kids Undergoing Surgery

Official title: Peripheral Perfusion Index as an Early Predictor of Successful Caudal Block in Pediatric Patients Undergoing Lower Abdominopelvic Surgeries Under General Anesthesia

Run by Ain Shams University · NCT06846983 · Data updated 2026-11-12

This study is testing if a special measurement called the peripheral perfusion index can help predict if a pain relief technique will work for young children having surgery.

Is this trial a fit for you?

Likely a good fit

Ideal candidates are pediatric patients aged 1-5 years scheduled for elective lower abdominopelvic surgeries under general anesthesia.

Probably not a fit

Patients with ASA physical status classes III or above, or those with certain neurological disorders or infections, may not benefit from this study.

What this trial studies

This study aims to evaluate the effectiveness of the peripheral perfusion index (PPI) as an early predictor of successful caudal block in pediatric patients undergoing elective lower abdominopelvic surgeries under general anesthesia. Preoperative assessments will include a thorough medical history, clinical examination, and standard laboratory tests. Patients will be monitored during surgery using various methods, including pulse oximetry to measure PPI, which will be applied to the patient's toe. The study will focus on children aged 1-5 years and will adhere to strict preoperative fasting guidelines.

Why it matters

Potential benefit: If successful, this study could improve the predictability of caudal block effectiveness, leading to better pain management in pediatric surgeries.

How similar studies have gone: While the use of peripheral perfusion index in this context is relatively novel, similar studies have shown promise in improving anesthesia outcomes.
