Randomized Controlled TrialMotor-sparing effect of iPACK (interspace between the popliteal artery and capsule of the posterior knee) block versus tibial nerve block after total knee arthroplasty: a randomized controlled trial.
An ultrasound-guided anesthetic technique targeting the interspace between the popliteal artery and capsule of the posterior knee (iPACK) can provide posterior knee analgesia with preserved motor function after total knee arthroplasty (TKA). This study compared the peroneal nerve motor-sparing effects of iPACK block and tibial nerve block (TNB) when combined with local infiltration analgesia (LIA) and continuous adductor canal block (CACB). ⋯ Compared with TNB, iPACK1 and iPACK2 preserved CPN and tibial nerve motor function to a greater extent. However, iPACK2 did not demonstrate complete CPN and tibial nerve motor blockade while maintaining effective posterior knee pain relief.

Randomized Controlled TrialEvaluation of ultrasound-guided rhomboid intercostal nerve block for postoperative analgesia in breast cancer surgery: a prospective, randomized controlled trial.
Mastectomy has many potential sources of pain. Rhomboid intercostal block (RIB) is a recently described plane block. The primary hypothesis of the study is that ultrasound-guided RIB combined with general anesthesia would accelerate global quality of recovery scores of patients following mastectomy surgery. Secondary hypothesis is that RIB would reduce postoperative opioid consumption, pain scores, and the need for rescue analgesia. ⋯ In the current study, ultrasound-guided RIB promoted enhanced recovery and decreased opioid consumption after mastectomy surgery.
