modified pectoral nerves block
serratus plane block
Modified pectoral nerves block with general anesthesia. Using the ultrasound, 10 ml of bupivacaine 0.25% with epinephrine 5 ug/ml will be injected in the plane between the pectoralis major and minor muscles. And another 20 ml of bupivacaine 0.25% with epinephrine 5 ug/ml will be injected in the plane between the pectoralis minor and the serratus anterior muscles.
Serratus plane block with general anesthesia. Using the ultrasound, 0.4 ml of bupivacaine 0.25% with epinephrine 5 ug/ml will be injected in the plane between the serratus anterior muscle and the underlying ribs.
