Ultrasound-guided erector spine plane block (ESPB) utilization in managing refractory renal colic pain in the emergency department

Due to the acute and terrible pain that patients with renal colic experience,the most essential therapeutic priority for these patients in the emergency department(ED)is to reduce pain.[1]Although numerous medications are utilized to reduce pain in patients with acute renal colic,no therapy has yet been developed to totally and quickly relieve pain.[2,3]Intravenous opioids and nonsteroidal anti-inflammatory drugs(NSAIDs)are commonly administered intravenously to control pain in these patients in the ED;however,the need for frequent monitoring for possible complications and relatively slow-acting features render these strategies undesirable.
