Ideal Initial Bolus and Infusion Rate for Erector Spinae Plane Block Catheters
January 22, 2020 updated by: Virginia Commonwealth University
This study would like to identify the best starting dose and infusion rate for nerve blocks and nerve catheters related to the erector spinae plane block that can improve functional status and pain control on cardiac surgery patients and minimize the necessity for opioid pain control using a continuous reassessment model.

Detailed Description
The study will continue taking steps in helping to identify the role erector spinae plane nerve blocks have in thoracic surgery.
This is a relatively new nerve block (first identified and described in 2016) and the studies that have been done and the case series that have been reported have been very promising in supporting its role in thoracic surgery.
As it is a plane block (not around a specific nerve but in a general area), larger volumes and doses often have to be used in these sorts of blocks (such as a transverses abdominalis plane block) to get good spread of the local anesthetic in the plane to reach the desired nerves that pass through this plane with one injection.
Our hospital has been doing these blocks for patients as a standard of care for them, but this study will take a closer look to see if there is an optimal dose and volume of medicine to improve patients' functional status and pain control to minimize the need for opioids.
The study will use a continuous reassessment model to determine the optimal dose.

Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
---|---|
Experimental: Bilateral catheters
patients receiving bilateral catheters (such as for patients undergoing sternotomies/midline incisions or with planned bilateral thoracotomy incisions)
|
Variable initial post-operative dose of 10cc to 40cc bilaterally with a variable programmed dose to be repeated afterward of 10cc to 40cc of 0.2% ropivacaine every 6 hours bilaterally.
|
Experimental: Single catheter
patients who only have one catheter in place (such as in patients who have unilateral thoracotomies and not midline sternotomies)
|
Variable initial post-operative dose of 10cc to 40cc unilaterally with a variable programmed dose to be repeated afterward of 10cc to 40cc of 0.2% ropivacaine every 6 hours unilaterally.
