Cervical erector spinae plane block catheter for shoulder disarticulation surgery
- 175 Downloads
To the Editor,
For shoulder disarticulation surgery, a continuous brachial plexus (BP) block is suboptimal because of close proximity to the surgical field and inadequate anesthetic coverage for thoracic dermatomes. Recently, a novel description was published outlining the use of a T2–3 erector spinae plane (ESP) catheter advanced into a cervical location from the thoracic level to serve as an alternative to a BP block for complex upper extremity procedures.1 Instead of facing potential challenges from threading an ESP catheter from the thoracic region, we report (with patient consent) a similar case of a patient undergoing a unilateral shoulder disarticulation but with an ESP catheterization at the C7 level.
