Confirmation of success rate of landmark‐based caudal blockade in children using ultrasound: A prospective analysis
Paediatric Anaesthesia Aug 19, 2020
Boretsky KR, Camelo C, Waisel DB, et al. - Among 30 children (ages 1 month to 7 years) undergoing surgical procedures with consent for caudal blockade, researchers evaluated the success rate of conventional landmark‐based caudal technique using ultrasound‐imaging in this prospective observational study. They identified that ultrasound‐imaging showed 80% success to correct positioning of the needle tip and local anesthetic in the epidural space. With the use of real‐time ultrasound‐imaging, subsequent successful positioning of all improperly positioned needles was achieved. Mean time for confirmatory ultrasound‐imaging (SD; range) was reported to be 1 minute (0.3; 1‐3). Overall, experts concluded the utility of ultrasound‐imaging in identifying proper needle placement in the sacral epidural canal as well as in facilitating subsequent corrected placement.
