Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The ideal method to predict successful caudal block is still lacking. We hypothesized that the change in femoral artery Doppler indices could accurately predict successful caudal block

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

after institutional research ethics committee approval and obtaining informed consent from each participant. an experienced operator will examine the femoral artery using pulsed wave Doppler at baseline and 15 and 30 minutes after caudal block adminestration
