Management of postoperative pain relief is largely inadequate. Despite the recent advances in pain management, postoperative pain incidence has not decreased; most patients still experience severe pain after major surgery. Poorly or inadequately controlled pain was reported to be linked to prolonged hospitalization, decreased patient satisfaction, the risk of readmission, and a higher incidence of postoperative complications.

In major abdominal surgeries, the gold standard for postoperative analgesia is thoracic epidural analgesia. Nevertheless, there are many concerns regarding its side effects, including motor blockade and hypotension. Moreover, many researchers interrogated its role as it may increase the risk of serious problems such as epidural hematoma and abscess. As an alternative, some surgeons proposed the transversus abdominis plane (TAP); however, a recent meta-analysis established that TAP block was of minimal effect. The erector spinae plane block (ESPB) is a fairly original paraspinal plane block that was first designated for thoracic analgesia. Recently, some reports showed that it could offer effective and widespread somatic and visceral abdominal analgesia. Bilateral continuous ESP blockade represents a respected alternative to thoracic epidural analgesia. The local injection under the erector spinae muscle is carried out in this technique, which is estimated to spread a paravertebral of three vertebral levels cranially and four levels caudally. It was designated that the injected local anesthesia passes across the costotransverse foramina and blocks the ventral and dorsal rami of spinal nerves, causing a sensory blockade over the anterolateral thorax. The dermatomes enclosed by ESPB depend on the site of entry, the volume, and the concentration of the local anesthetic used. This RCT aimed to assess the analgesic effectiveness of US-guided bilateral erector spinae plane block in patients undergoing elective colectomy. This randomized controlled trial was designed to assess the analgesic effectiveness of bilateral US-guided erector spinae plane blocks (ESPB) in patients undergoing elective colectomy surgery.
