Abstract:

Background & Objectives: In the event that gynecologic cancer surgery (GC surgery) is going to be accompanied with extreme pain, many localized blocks will be provided. The quadratus lumborum block, often known as a QLB, is a fascial plane block that was developed relatively recently for the therapy of post-abdominal surgery discomfort. In the current study, a comparison is made between the effectiveness and safety of thoracic paravertebral block (TPVB) and quadratus lumborum block (QLB) in patients undergoing GC surgery.

Background Pain management is important for ensuring early mobilization after hip arthroplasty; however, the optimal components remain controversial. Recently, the quadratus lumborum block has been proposed as an analgesic option. The current study tested the hypothesis that the posterior quadratus lumborum block combined with multimodal analgesia decreases morphine consumption after hip arthroplasty.

Background: As strong analgesics, opioids provide the analgesic component of general anesthesia, but they have bidirectional effects on the immune system, promoting the production of pro-inflammatory factors. The idea of opioid-free anesthesia is to replace the analgesic effect of opioids in the treatment of acute pain with comparably effective drugs that do not affect the immune system and thereby decrease the production of inflammatory factors. Therefore, this study aims to observe the effect of opioid-free esketamine anesthesia based on quadratus lumborum block on inflammatory factors in pa
