Randomized Controlled TrialEffect of intravenous dexamethasone on the duration of postoperative analgesia for popliteal sciatic nerve block: a randomized, double-blind, placebo-controlled study.
Intravenous (IV) dexamethasone prolongs the duration of a peripheral nerve block; however, there is little available information about its optimal effective dose. This study aimed to evaluate the effects of three different doses of IV dexamethasone on the duration of postoperative analgesia to determine the optimal effective dose for a sciatic nerve block. ⋯ This study demonstrated that compared to the controls, only IV dexamethasone 10 mg increased the duration of postoperative analgesia following a sciatic nerve block for foot and ankle surgery without the occurrence of adverse events.

Review Meta AnalysisDoes the addition of iPACK to adductor canal block in the presence or absence of periarticular local anesthetic infiltration improve analgesic and functional outcomes following total knee arthroplasty? A systematic review and meta-analysis.
When combined with adductor canal block (ACB), local anesthetic infiltration between popliteal artery and capsule of knee (iPACK) is purported to improve pain following total knee arthroplasty (TKA). However, the analgesic benefits of adding iPACK to ACB in the setting of surgeon-administered periarticular local infiltration analgesia (LIA) are unclear. ⋯ Adding iPACK to ACB in the setting of periarticular LIA does not improve analgesic outcomes following TKA. In the absence of LIA, adding iPACK to ACB reduces pain up to 24 hours and enhances functional recovery. Our findings do not support the addition of iPACK to ACB when LIA is routinely administered.

Meta AnalysisThe opioid sparing effect of erector spinae plane block for various surgeries: a meta-analysis of randomized-controlled trials.
The erector spinae plane block (ESPB) is a newer fascial plane block which has been broadly applied for postoperative analgesia after various surgeries, but the effectiveness in these populations is not well established. ⋯ ESPB may be a useful addition to the multimodal analgesic regimen for a variety of surgeries especially when the alternative is no block. Unanswered questions include determining of the mechanism of action, refining of the EPSB technique, and establishing recommended local anesthetic dose and volume.
