Study summary

Dexmedetomidine used as an Additive for Ipack Block in Knee Surgery

Read the detailed description

Many types of analgesia used but multimodal analgesia showed best results The interspace between the popliteal artery and capsule of the posterior knee (IPACK) block aims to blockade of sciatic nerve terminal branches for analgesia without motor affection

. (IPACK) block is a motor power sparing procedure that involves injecting local anesthetic into the space between the popliteal artery and the posterior capsule of the knee in order to treat posterior knee pain
