简要总结
Effect of perineurial dexamethasone and dexmedetomidine on popliteal nerve block duration for pediatric, ankle or foot surgery
详细描述
This study is proposed to explore the effect of perineurial Dexamethasone and Dexmedetomidine on erector spinal plane block duration for pediatric, idiopathic scoliosis surgery.
After scoliosis surgery, children need good analgesia. Peripheral nerve blocks have provided a safe, effective method to control early postoperative pain when symptoms are most severe.
The safety of local anesthesia is essential in children due to the much lower toxicity threshold of local anesthetics. An effective adjuvant, such as Dexamethasone or Dexmedetomidine, could allow for a higher dilution of local anesthetics while maintaining and enhancing their analgesic effect.
There is considerable research where intravenous and perineural dexamethasone and Dexmedetomidine use has been compared in adults. However, there is a massive lack of research regarding children.
In this study, investigators compare perineural Dexamethasone and Dexmedetomidine. Group 2 has dexamethasone doses of 0.1mg/kg, and group 3 has 0,1ug/kg Dexmedetomidine added to the local anesthetic.
