Review Meta Analysis Comparative StudyPerineural Versus Intravenous Dexamethasone as an Adjuvant for Peripheral Nerve Blocks: A Systematic Review and Meta-Analysis.
Dexamethasone is a useful adjuvant in regional anesthesia that is used to prolong the duration of analgesia for peripheral nerve blocks. Recent randomized controlled trials (RCTs) have demonstrated conflicting results as to whether perineural versus intravenous (IV) administration is superior in this regard, and the perineural use of dexamethasone remains off-label. Therefore, we sought to perform a systematic review and meta-analysis of RCTs. ⋯ Perineural dexamethasone prolongs the duration of analgesia across the RCTs included in our meta-analysis. The magnitude of effect of 3.77 hours raises the question as to whether perineural dexamethasone should be administered routinely over its IV counterpart-or reserved for selected patients where such prolongation would be clinically important.

Randomized Controlled TrialA Longitudinal Supra-Inguinal Fascia Iliaca Compartment Block Reduces Morphine Consumption After Total Hip Arthroplasty.
The role of a fascia iliaca compartment block (FICB) for postoperative analgesia after total hip arthroplasty (THA) remains questionable. High-dose local anesthetics and a proximal injection site may be essential for successful analgesia. High-dose local anesthetics may pose a risk for local anesthetic systemic toxicity. We hypothesized that a high-dose longitudinal supra-inguinal FICB is safe and decreases postoperative morphine consumption after anterior approach THA. ⋯ We conclude that a high-dose longitudinal supra-inguinal FICB reduces postoperative morphine requirements after anterior approach THA.Clinical Trials Registry: EU Clinical Trials Register. www.clinicaltrialsregister.eu #2014-002122-12.
