Caudal Block
Conditions
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

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Accuracy of Change in pulsatility index (PI) to predict successful caudal block | baseline and 15 minutes after the block | The change in PI measured at baseline and 15 minutes after the block |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Accuracy of the change in resistive index to successful caudal block | baseline and 15 minutes | The change in RI at baseline and 15 minutes after the block |
| accuracy of change in waveform morphology to predict successful caudal block | baseline and 15 minutes after the block | The change in femoral artery waveform from triphasic to a monophasic wave |
