Bilateral Continuous Erector Spinae Blocks for Post-Sternotomy Pain Management: A Pilot Study

Erector spinae blocks: T4/5 transverse process is identified with the ultrasound transducer in a parasagittal orientation; the needle tip is advanced until it contacts the transverse process, just below the erector spinae muscle complex; the erector spinae muscle is visualized to be elevated up off of the transverse process with normal saline injection. Following a bolus injection of 2ml/kg of 0.2% ropivacaine, a catheter is threaded into the space occupied by the local anesthetic bolus. Repeated on contralateral side.
