Abstract
Buckhound: Paravertebral blocks (PVBs) were first performed in 1905 and became a popular technique for the provision of analgesia in the early part of the twentieth century. However, their use declined over the years until a publication by Eason and Wyatt in 1979 began a renaissance.
Objective: The aim of this study is to evaluate the efficacy of US guided paravertebral block compared to systemic opioid, Identify the effect of US-guided paravertebral block on analgesic requirement needed to control post-operative pain and shortening length of hospital stay and to assess surgeon and patient satisfaction.
Methodology: Forty female patients scheduled for elective breast surgery (modified radical mastectomy) for treatment of breast cancer. They were divided into 2 groups each constitutes of twenty patients (n= 20).
Results: Comparison occurred between two groups in regards of degree of postoperative pain relief, effect on hemodynamic stability, intraoperative fentanyl consumption, first rescue of analgesia, total morphine consumption in 24 hours postoperatively postoperative nausea and vomiting and time of hospital discharge.
Conclusion: This study demonstrated that single injection thoracic PVB at the level of the 3rd thoracic vertebral space together with general anesthesia could provide better perioperative pain control, reduce both intraoperative and postoperative opioid requirement, PONV and shorten length of hospital stay in patients undergoing MRM.
