Breast cancer affecting 2.1 million women per year. It causes the largest number of cancer-related deaths among women. It is estimated that 627,000 women died from breast cancer in 2018, which is around 15 percent of all female cancer deaths. While breast cancer rates are higher among women in more developed regions, rates are raising globally (Ryser et al., 2019).
A modified radical mastectomy is an extensive operation, manipulation and stretching of the pectoralis muscles act as a source of perioperative myofascial pain. One or 2 drains may be also placed through separate inferior-lateral incisions and can be additional sources of pain (Kirby and Helena, 2018).
Multimodal analgesia is recommended for all postoperative analgesic plans. This may require the administration, unless contraindicated, of basic analgesics, such as paracetamol, non-steroidal anti-inflammatory drugs and opioids which can cause a broad range of adverse effects in the postoperative period. In recent anesthetic practice, unconventional regional analgesic techniques like local anaesthetic infiltration, thoracic Epidural, Serratus Anterior Plane block, Paravertebral block and Pecs block should be considered because they lower the usage of opiates required and provide better pain relief. Recently, the use of ultrasound in anesthesia increases the success rate of the block and decreases the incidence of variable complications (Von Minckwitz et al., 2019).
The goal of this study is to compare the efficacy of the ultrasound guided paravertebral block and pectoral nerve block in decreasing the intensity of postoperative pain and to compare hemodynamics effect, safety, and side effects of the two blocks.
Our study showed that Pecs block performed in patients undergoing MRM is a safe, effective technique, resulted in significantly prolonged duration of postoperative analgesia, less intraoperative and postoperative opioids consumption, less pain intensity in comparison with TPVB. Therefore, the PECs block can be used safely for postoperative analgesia in patients undergoing breast surgeries with axillary dissection
