ltrasound Echogram Oriented Anatomical Measurement for Caudal Epidural Anesthesia in Pediatric Patients - Ultrasound Echogram Oriented Anatomical Measurement for Caudal Anesthesia in Pediatric Patients

Two patients were excluded because the superolateral sacral crests and sacral hiatus could not be palpated. The base of the triangle increased in proportion to age up to 10 years old, with a significant correlation between age and the length of the base. The triangle was not an equilateral triangle under 7 years old. The sacral hiatus could be identified by ultrasound and we could confirm expansion of the epidural space in all patients.
