Assessment of catheter position using chest CT in adults undergoing erector spinae plane analgesia for rib fractures: a retrospective cohort study
Authors' conclusion
Most ESP catheters were found superficial to the fascial plane in the days following their placement. The median distance between the catheter and the ESP is between 23 and 25 mm.
