Summary

compare between ultrasound guided erector spinae plane block and ultrasound guided paravertebral block on acute and chronic post mastectomy pain

Detailed description

Management of postoperative analgesia following breast surgery extending beyond a simple lumpectomy can sometimes be a challenge, especially when such surgery is being performed as a day-case procedure. Patients undergoing mastectomy have a very high possibility of developing postsurgical pain syndrome, as high as 20% to 50%.There has been some evidence to suggest regional analgesia techniques reduce the incidence of postsurgical pain in patients undergoing mastectomy. This underlines the importance of performing regional anaesthetic and analgesic techniques for postoperative analgesia following breast surgery.There are many techniques of regional analgesia as thorasic epidural block , paravertebral block , PECS1 block ,PECS2 block , and recently erector spinae plan block.Paravertebral blocks have superseded thoracic epidurals when it comes to choice of a regional anaesthesia technique to provide analgesia for breast surgery.The injection of local anaesthetic solution in the paravertebral space results in a unilateral block, which is sensory, motor, and sympathetic. The uptake of the local anaesthetic solution is enhanced due to the absence of fascial sheaths binding the spinal nerves.TPVB produces ipsilateral somatic and sympathetic nerve blockade due to a direct effect of the local anesthetic on the somatic and sympathetic nerves in the TPVS, extension into the intercostal space laterally, and the epidural space medially. Ultrasound-guided erector spinae plane (US-ESP) block is a novel analgesic technique, in which local anaesthetic is injected into fascial plane deep to erector spinae muscle. It is possible to block the dorsal and ventral rami of the spinal nerve depending on the level of injection and amount of local anaesthetic injected. Erector spinae block (ESP) leads to effective post-operative analgesia where it is performed at T4-5 level for breast cancer and thoracic surgery , when performed bilaterally it has been reported to be as effective as thoracic epidural analgesia.The drug spreads in craniocaudal fashion over several levels as the erector spinae fascia extends from nuchal fascia cranially to the sacrum caudally. Forero et al. recently described US-ESP block for thoracic neuropathic pain. This block could be effective in both acute post-operative thoracic and abdominal surgeries and also neuropathic pain in these regions.
