Randomized Controlled Trial Comparative StudyComparison of migration rates between traditional and tunneled adductor canal block catheters: a randomized controlled trial.
Total knee arthroplasty is associated with significant postoperative pain. Continuous adductor canal blocks via an inserted adductor canal catheter are effective analgesia interventions with the advantage of decreasing quadriceps weakness and the potential of extending the analgesic effect. The classical adductor canal catheter insertion technique may have a high likelihood of catheter dislodgement out of the canal. The interfascial plane between the sartorius muscle and femoral artery (ISAFE) approach has the potential of decreasing the adductor canal catheter migration. The purpose of this study was to evaluate the incidence of catheter dislodgment to outside the adductor canal, for ISAFE and classical approaches. We hypothesized that ISAFE approach would result in a lower dislodgment rate. ⋯ ISAFE group had a significantly lower rate of dislodgement at 24 hours. The continuous adductor canal block analgesic benefit for knee arthroplasty depends on the position of the tip of the catheter inside the adductor canal.

Randomized Controlled Trial Comparative StudySerratus plane block versus standard of care for pain control after totally endoscopic aortic valve replacement: a double-blind, randomized controlled, superiority trial.
Serratus anterior plane block has been proposed to reduce opioid requirements after minimally invasive cardiac surgery, but high-quality evidence is lacking. ⋯ Combined deep and superficial single-injection serratus anterior plane block is superior to standard of care in reducing opioid requirements and postoperative pain intensity up to 24 hours after totally endoscopic aortic valve replacement.
