Observational Study
Association between plasma tau and postoperative delirium incidence and severity: a prospective observational study.
Postoperative delirium is associated with increases in the neuronal injury biomarker, neurofilament light (NfL). Here we tested whether two other biomarkers, glial fibrillary acidic protein (GFAP) and tau, are associated with postoperative delirium. ⋯ NCT02926417 and NCT03124303.

Perioperative cannabis use: a longitudinal study of associated clinical characteristics and surgical outcomes.
Despite increases in cannabis use generally and for pain management, data regarding cannabis use in patients undergoing surgery are lacking. This study examined the prevalence of cannabis use among patients undergoing elective surgery and explored differences in clinical characteristics and surgical outcomes between cannabis users and non-cannabis users. ⋯ Cannabis use is relatively low in this surgical population, yet cannabis users have higher clinical pain, poorer scores on quality of life indicators, and higher opioid use before and after surgery. Cannabis users reported similar surgical outcomes, suggesting that cannabis use did not impede recovery.

Randomized Controlled TrialQuadratus lumborum block type 3 versus lumbar plexus block in hip replacement surgery: a randomized, prospective, non-inferiority study.
The posterior lumbar plexus block (LPB) has been used for decades to provide acute pain management after hip surgery. Unfamiliarity with the technique and its perceived difficulty, potential risks, and possible adverse effects such as quadriceps weakness have limited broader use. The quadratus lumborum block (QLB) has been reported to be effective for postoperative pain control following hip surgery and may thus offer another regional alternative for practitioners. This study hypothesized that the QLB type 3 (QLB3) can produce a non-inferior analgesic effect compared with LPB for primary hip replacement. ⋯ This trial supported the hypothesis that the QLB3 yields non-inferior analgesia compared with LPB for hip replacement surgery.

Effective pain management for patients undergoing orthopedic surgery, using pharmacological and nonpharmacological strategies, is essential. This pilot study evaluated music as an adjuvant therapy with prescribed analgesics to reduce acute pain and analgesic use among patients undergoing arthroplasty surgery. ⋯ Study findings provide further evidence for the effectiveness of music listening, combined with analgesics, for reducing postsurgical pain, and extend the literature by examining music listening postdischarge. Music listening is an effective adjuvant pain management strategy. It is easy to administer, accessible, and affordable. Patient education is needed to encourage patients to continue to use music to reduce pain at home during the postoperative recovery period.
