Lidocaine and ropivacaine are routinely used for subcutaneous local anesthesia in pacemaker implantation, combined with fentanyl needle micropump to maintain injection. However, these simple local anesthesia methods often fail to produce sufficient analgesia in deeper subcutaneous areas. This study adopted ultrasound-guided precision nerve block anesthesia. Through contrast analysis, it was clear
