简要总结
Adequate pain management following modified radical mastectomy (MRM) is crucial for early ambulation and patient satisfaction. Breast cancer is the most common malignancy in females, with an increasing incidence in recent years. Surgery is one of the mainstays of therapy for breast cancer, and modified radical mastectomy (MRM) is the most effective and common type of invasive surgical treatment. Post-mastectomy pain syndrome (PMPS) is a surgical complication of breast surgery characterized by chronic neuropathic pain. The aim of this study is to investigate the efficacy and safety of single injection CTB versus SAPB on post-operative acute pain as a part of a multimodal analgesia plan in patients undergoing MRM.
详细描述
Patients will be divided randomly by the computer into three groups, group (A): will receive serratus anterior plane block, group (B): will receive costotransverse block and group(C): patient controlled analgesia group (PCA).
Group (A) (SAPB):
SAPB will be performed using an ultrasound machine with a high-frequency linear probe . All patients will be in lateral position to perform the block. At the level of the fourth rib with 45-degree angle, targeting the plane between the latissimus dorsi and serratus muscles, SAPB block will be performed unilaterally on the ipsilateral side of surgery.
Group (B) (CTB):
CTB will be performed using an ultrasound machine with a high-frequency linear probe. All patients will be in lateral position to perform the block. CTB block will be performed unilaterally on the ipsilateral side of surgery at the level of fourth rib.

结局指标
主要结局
Visual Analogue Scale score at 0,6,12 and 24 hour post-operatively. visual analogue scale is a scale from 0 to 10, 0 represent no pain at all and 10 represent the worst pain
时间窗: 24 hour post-operative
Visual Analogue Scale score will be assessed at both rest and arm elevation
次要结局
