This scoping review investigates the optimal combination of motor-sparing analgesic interventions for patients undergoing total knee replacement (TKR). ⋯ The optimal analgesic strategy for TKR may include a combination of different analgesic modalities (periarticular infiltration, femoral triangle blocks, obturator nerve block). Future trials are required to investigate the incremental benefits provided by local anesthetic infiltration between the popliteal artery and the capsule of the knee (IPACK), popliteal plexus block and genicular nerve block.

The operating room (OR) is a busy environment with multiple opportunities for distraction. A well-trained anesthesiologist or certified registered nurse anesthetist (CRNA) should remain focused on providing excellent patient care despite these potential distractions. The purpose of this narrative review is to present the multiple types of OR distractions and evaluate each for their level of distraction and their likely impact on patient safety. ⋯ The impact of OR distractions on patient outcomes deserves more vigorous investigation. We must provide anesthesia trainees with the skills to remain vigilant despite numerous and varied OR distractions while also attempting to reduce such OR distractions to improve patient safety. Further research is needed to inform the institution of policies to lessen unnecessary OR distractions.

This narrative review discusses the anatomy, mechanism of action, techniques, pharmacology, indications, complications and substitutes for erector spinae plane (ESP) blocks. ⋯ In recent years, ESP blocks have become the topic of considerable clinical interest. Future trials are required to investigate their optimal technique, dose of local anesthetic and perineural adjuvants. Moreover, additional investigation should compare ESP blocks with robust multimodal analgesic regimens as well as truncal blocks such as thoracic epidural block, midpoint transverse process to pleura block, PECS block, quadratus lumborum block, and transversus abdominis plane block.

Meta Analysis
Perioperative intravenous S-ketamine for acute postoperative pain in adults: A systematic review and meta-analysis.
To evaluate the effectiveness and safety of S-ketamine for pain relief and analgesic consumption in surgical patients. ⋯ Intravenous S-ketamine as an adjunct to general anesthesia is effective for assisting analgesia and decreases the intensity of pain and opioid requirements in a short period of time after surgery, but it may increase the psychotomimetic adverse event rate. Overall, the level of certainty is moderate to low.

To review all randomized controlled trials (RCTs) comparing the analgesic efficacy of adductor canal block (ACB), periarticular infiltration (PAI), and any other mode of these treatments in analgesia, such as PAI with liposomal bupivacaine (LB), continuous adductor canal block (cACB) or ACB + PAI, after total knee arthroplasty (TKA). ⋯ PROSPERO (CRD 42020168102).
