Clinical Trial Summary

Regional analgesia via caudal neuraxial blockade provides pain relief for pediatric patients following urological and lower extremity procedures. The injection of local anesthetic into the caudal epidural space causes a sensory loss. This sympathetic blockade in turn causes a vasodilation, or increased blood flow, to the lower extremities.

The purpose of this study is to determine whether the FLIR ONE thermographic camera, a smartphone attachment which utilizes an application ("app") to measure the temperature at a site on an image of the lower extremity, will be able to differentiate between caudal, non-caudal, and failed caudal images.

Outcome

Type Measure Description Time frame Safety issue
Primary Predictive value of FLIR ONE Reviewers blinded to intervention groups will asses patient pre-caudal, 1, 2, 3, 4, and 5 minute post-caudal images and rate whether, based on the image, they believe the patient received a caudal or not. The sensitivity and specificity of the FLIR ONE as a diagnositic tol will then be determined. Assessments will be done through study completion, an average of 1 week following procedure.
Secondary Inter- and Intra- rater reliability Reviewers will evaluate patient image at two separate ties at least a week apart. Recorded images will be compared within and between reviewers. Assessments will be done through study completion, an average of 1 week following procedure.
Secondary Temperature differences between pre-caudal and 5 minute post-caudal images Temperature differences between pre-caudal and 5 minute images will be summarized in both groups. Images in the non-caudal group will be taken at similar time points following anesthesia induction relative to caudal group patients. Images will be captured prior to caudal and 5 minutes immediately afterwards. Assessments will be done through study completion, an average of 1 week following procedure.
