Change in Femoral Artery Doppler to Predict Successful Caudal Block

Cairo University40 enrolled

Overview

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

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

Outcomes

Primary Outcomes

Accuracy of Change in pulsatility index (PI) to predict successful caudal block

The change in PI measured at baseline and 15 minutes after the block

Time frame: baseline and 15 minutes after the block

Secondary Outcomes

Accuracy of the change in resistive index to successful caudal block

The change in RI at baseline and 15 minutes after the block

Time frame: baseline and 15 minutes

accuracy of change in waveform morphology to predict successful caudal block

The change in femoral artery waveform from triphasic to a monophasic wave

Time frame: baseline and 15 minutes after the block
