Clinical Trial Summary

Thoracic epidural anesthesia (TEA) and paravertebral block (PVB) have been utilized to give perioperative regional anesthesia in the trunk. TEA is technically troublesome in some cases, and is associated with a danger of serious complications, such as epidural hematoma, nerve injury, and hypotension. PVB has the benefit of perception of the needle position using ultrasonography. However, PVB is also additionally connected with a danger of serious complications, such as pneumothorax, hypotension, or nerve injury. Newer approaches to deal with PVB have been the focal point of numerous techniques lately; these methodologies incorporate retrolaminar block (RLB) and erector spinae plane block (ESPB)


Clinical Trial Description

Modified radical mastectomy is one of the commonly performed breast surgery. Postoperative pain following mastectomy should be minimized, as in a number of women it may chronically persist for months in the form of post-mastectomy pain syndrome. Morphine administration for acute pain after mastectomy surgery has many side effects. Regional block techniques as para-vertebral block and thoracic epidural anesthesia have possible complications and technical difficulties. The new alternative regional techniques such as erector spinae plane block and retrolaminar block are clinical trials for providing a safe and easy with good hemodynamic and recovery profile with adequate perioperative analgesia for a large section of patients undergoing mastectomy operation in order to reduce opioids consumption and subsequently avoid opioid-related adverse effects. As percent of post-operative rescue analgesia is 16.7% and 60% for RLB group and ESPB group respectively. So, sample size is 46 patients (23 patients in each group). Sample was calculated using OPEN EPI program with confidence level 95% and power 80%. ;
