Conditions

Caudal Block

Keywords

Femoral artery Doppler, Pulsatility index, Caudal block

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

Interventions

An experienced operator will conduct femoral artery examination for the change in Doppler indices namely pulsatility index, resisitive index, and waveform morphology
