Erector Spinae Plane Block for Acute Low Back Pain

Non-Specific low back pain (NSLB) is an important public health problem with a major economic and social impact. It is defined by the location of pain, between the lower rib margins and the lumbar vertebrae. Medical management of Non-Specific low back pain injury focuses on reducing pain and its consequences. Nowadays, no strategy has shown optimal effectiveness to improve outcome substantially. The ultrasound-guided erector spinae plane block (ESPB) is a well-known intermuscular compartment block. In the absence of red flag signs, ESPB can be performed for low back pain to reduce pain, decrease opiate requirements and limit emergency admissions for refractory pain. This study aims to evaluate the impact of the ESPB in patients suffering from NSLB.
