This study aims to compare between the effectiveness of Erector spinae plane block and thoracic paravertebral plane block in reducing the perioperative need of opioids in patients undergoing minimally invasive mitral valve replacement as part of ERAS.
In recent years , the popularity of ultrasound-guided fascial plane blocks has increased in achieving an effective postoperative analgesia and hence achieving enhanced recovery after surgery (ERAS) .~Mastering the use of ultrasound encourages anesthetists on the frequent use of regional anesthesia . Fascial plane blocks are increasingly becoming a part of multimodal analgesia as an alternative pain management strategy in cardiac surgery. Various regional techniques especially paravertebral plane blocks have been recently described to reduce the postoperative pain in cardiac surgery with enhanced recovery . Ultrasound-guided erector spinae plane block is a recently introduced technique for regional analgesia in thoracic neuropathic pain, rib fractures, and breast surgeries. This study aims to compare between the two techniques regarding their peri-operative analgesic effect and their impact on enhanced recovery after surgery.
