Utility of erector spinae plane block in thoracic surgery

Abstract

Abstract Background Thoracic surgeons have been incorporating enhanced recovery after surgery (ERAS) protocols into their practices, not only to reduce narcotic usage but also to improve complication rates and decrease lengths of stay. Here, we describe the utility of a regional block technique that can be used for patients undergoing urgent or elective thoracic surgical procedures or suffering from rib fractures. Methods We report our initial one-year experience with these erector spinae plane (ESP) blocks. Results ESP blocks were placed in 42 patients. The procedure was performed by a trained team of anesthesiologists and certified nurse practitioners. It included placement of a catheter on the ipsilateral chest, followed by a 20 ml of 0.2% ropivacaine bolus and continuous infusion. Patients were then followed by the regional team, as long as the catheter was in place. While it had some technical challenges, the block was effective in 83.3% of patients with no reported mortality or major complications. However, given the confounding factors of the study (such as simultaneous implementation of ERAS protocol) and heterogeneity of the patient population, a control group was difficult to ascertain and meaningful opioid consumption analysis was difficult to perform. Conclusions Regional blocks, such as the ESP block, complement fundamental ERAS principles and serve as an adjunct to the available armamentarium for non-narcotic ways to control pain in thoracic surgical and chest trauma patients. Continued collaboration between the thoracic surgeons and anesthesiologists is needed for its success.
