Research of the Effects of Pectoralis Nerve Block II and Erector Spina Plan Block in Breast Cancer Surgery
Research of the Effects of Pectoralis Nerve Block II and Erector Spina Plan Block in Breast Cancer Surgery
This study evaluates the analgesic effects of pectoralis nerve block (PECS II) and erector spinae plane block (ESP) in patients having segmental mastectomy and sentinel lymph node biopsy (SLNB). Each one-third of patients will have ESP block and pectoralis nerve block (PECS II) 30 min before general anesthesia , while other one-third of patients will have only general anesthesia.
It has been proven that PECS II and ESP both supply effective analgesia in the first 24 hours after mastectomy. But they do so by different mechanishms.
This study is to survey that ESP and PECS II may supply acute and chronic analgesia by reducing pain scores in the first 24 hours and 3 months after the surgery, also the comparison of the analgesic activity among themselves for acute / chronic pain and opioid consumption will be searched.
In this study patients are divided into three groups. Patients in PECS group will have PECS II block in a separate section from the operating rooms (PNB practice room). In addition, patient controlled analgesia (PCA) will be used in the first 24 hours postoperatively.
Patients in ESP group will have ESP block in a separate section from the operating rooms (PNB practice room). In addition, PCA will be used in the first 24 hours postoperatively.
Patients in control group will not be performed nerve block. Only general anesthesia (GA) will be performed in the operation room. In addition, PCA will be used in the first 24 hours postoperatively.
