Abstract
This study demonstrate that, ultrasound guided thoracic paravertebral block (TPVB) is an effective intraoperative and postoperative technique for surgical anaesthesia and analgesia for breast surgery (e.g. MRM). It offers a long-lasting effective analgesia with a significant decrease in anaesthetic and analgesic consumption, and with a high degree of patient satisfaction, decrease the incidence of PONV and shorten length of hospital stay. Ultrasound guidance helps identifying the paravertebral space (PVS), needle placement, and to real time monitor the spread of the local anesthetic around nerves which increase the efficacy of the block and minimize the risk of complications
