Change in Femoral Artery Doppler to Predict Successful Caudal Block

Recruiting

• Conditions: Caudal Block

• Registration Number: NCT06981780
• Lead Sponsor: Cairo University

Brief Summary

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

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
