Overview
Combining tegileridine PCIA with ICNB targeting peripheral nerves, may constitute an ideal analgesic model with complementary advantages. Thus potentially achieving the analgesic goal of "early pain relief, stable throughout the process, and rapid recovery," and may have a positive impact on reducing CPSP.
Description
Combining tegileridine PCIA with ICNB targeting peripheral nerves, may constitute an ideal analgesic model with complementary advantages. ICNB provides rapid and precise incision analgesia in the early postoperative period, effectively blocking the transmission of peripheral nociceptive stimuli to the central nervous system. tegileridine PCIA, on the other hand, enhances the function of the endogenous descending pain suppression system through its central G protein pathway activation, covering the pain period after the effect of ICNB wears off and components such as visceral referred pain. At the same time, it can effectively reduce side effects such as respiratory depression and nausea/vomiting, thus potentially achieving the analgesic goal of "early pain relief, stable throughout the process, and rapid recovery," and may have a positive impact on reducing CPSP.
