Erector Spinae Plane Block for Minimally Invasive Mitral Valve Surgery
Erector Spinae Plane Block for Minimally Invasive Mitral Valve Surgery
The goal of this project is to study whether local anesthetic via the erector spinae plane
 (ESP) block may be beneficial in minimally invasive mitral valve surgery (MIMVS).
This is a double blinded randomized controlled trial comparing a control group receiving
 cryoablation and sham block with an intervention group receiving cryoablation and ESP
 catheter. The primary outcome is total oral morphine equivalent (OME) consumption within the
 first 48 hours of recovery including intra-operative usage. Secondary outcomes to be
 evaluated would include pain scores, functional milestones like time to extubation, time to
 first PO intake, time to ambulation, time to chest tube removal, length of ICU and total
 hospital stay, complications, and patient satisfaction.
Inclusion Criteria:

 -  Previous history of sternotomy and cardiac surgery

 -  Allergy to ropivacaine

 -  Patients taking more than 60 OMEs per day

 -  Patients with coagulopathy or taking anticoagulant with laboratory findings
 contraindicated for ESP catheter
