Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
As a core technique in multimodal analgesia, peripheral nerve block plays an important role in controlling acute postoperative pain in breast cancer patients; it may also prevent the occurrence of CPSP. In our previous trial, use of paravertebral block reduced CPSP at six months after breast cancer surgery; the effect was more prominent in the subgroup of patients following mastectomy. But conclusions can not be achieved until now. Regional anesthesia is also supposed to produce favorable effects on long-term oncological outcomes, possibly by relieving surgery-related stress response and immunosuppression. But, again, available evidences are conflicting regarding regional block and long-term cancer outcomes.
The erector spinae plane block (ESPB) was first described by Forero in 2016 and provides excellent perioperative analgesia with minimal side effect in patients undergoing thoracic, breast, and spinal surgeries. As one of the interfacial plane block techniques, the ESPB targets dorsal and ventral rami of the spinal nerves from T2-T7; it may produce effect by diffusing into the paravertebral and intercostal spaces and spreading in both cephalic and caudal directions.
Dexmedetomidine is a highly selective α2-adrenoceptor agonist with sedative, analgesic and anti-anxiety properties. When used as an adjuvant to local anesthetics, dexmedetomidine prolongs the duration nerve block and decreased the requirement of postoperative analgesia.
The investigators hypothesize that, for breast cancer patients undergoing mastectomy, ESPB (with 0.5% ropivacaine 35 ml combined with dexmedetomidine 1 microgram/kg) can reduce the occurrence of CPSP. The purpose of this randomized controlled trial is to investigate the impact of ESPB with adjuvant dexmedetomidine on the incidence of CPSP in breast cancer patients after mastectomy. We will also observe the effect of ESPB on long-term prognosis in this patient population.
