Erector Spinae Plane Block for Minimal Invasive Cardiac Surgery (Heart-Port).

Minimally invasive cardiac surgery is performed through a right thoracotomy, the pain management of this surgery is of great importance. Regional techniques such as thoracic epidural anesthesia or paravertebral block are excellent techniques for the management of postoperative pain in thoracic surgery but they have disadvantages that make it difficult to use in this surgery. On the one hand, anticoagulation in these patients increases the risk of complications related to the use of neuraxial techniques and, on the other hand, the technical difficulty of paravertebral block. The erector of the spine block is a technically simple block and with a low risk of associated complications. The aim of the study is to evaluate the feasibility and benefits in the relationship of postoperative pain management in patients undergoing minimally invasive cardiac surgery when using continuous unilateral blockade of the erector in a small cohort of patients.
