Clinical Trial Summary

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.

Description:

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.

Intervention

Procedure:
• Thoracic erector spinae plane block
After induction of general Anaesthesia,a high frequency ultrasound probe will be placed in a longitudinal orientation 3 cm from the midline. Once the erector spinal muscle and the transverse processes are identified, spinal needle will be inserted after standard skin disinfection in a caudal to cephalad direction using a sterile probe cover until the tip lay in the interfacial plane deep to the erector spinal muscle. After hydrolocalization with ml normal saline, this plane will be opened and 20 ml of 0.25 %bupivacaine will be administered for block performance
• Thoracic paravertebral plane block
After induction of general Anaesthesia ,with the probe in the longitudinal paramedian position, it is then moved from medial to lateral direction to appreciate the saw tooth appearance of the facet joints close to the midline which changes to long finger-like shadow of the transverse process as the probe is moved slightly laterally. Repositioning the probe over the transverse process ensuring the space of interest is in the middle of the probe once again one should appreciate the intercostal muscles and the dense bright white line of the pleura in between the shadows of the transverse processes. The needle is then introduced at the caudal end of the probe in plane in a caudal to cranial direction aiming for the angle between the bottom of the transverse process and the pleura. Once position is confirmed, 20 ml of 0.25% bupivacaine will be administered for the block performance.
