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.

ReviewAnalgesia and anesthesia using the pericapsular nerve group block in hip surgery and hip fracture: a scoping review.
Pericapsular nerve group (PENG) block is a novel regional analgesia technique to reduce pain after hip surgery and hip fractures. This review was conducted to summarize current literature. ⋯ Current evidence of using PENG block for hip surgery or hip pain is limited to case reports and case series only. PENG block is a promising regional analgesia technique as an alternative to other regional nerve blocks such as femoral nerve block or iliac fascia nerve block. Observational and experimental studies are required to determine the effectiveness, efficacy and safety of the PENG block.

Randomized Controlled TrialClinical effect of normal saline injectate into interscalene nerve block catheters given within one hour of local anesthetic bolus on analgesia and hemidiaphragmatic paralysis.
Previous case reports describe the reversal of phrenic nerve blockade from the interscalene nerve block using normal saline injectate washout. This randomized clinical trial aimed to evaluate whether using normal saline injectate to wash out local anesthetic from an interscalene nerve block catheter would restore phrenic nerve and diaphragm function, while preserving analgesia. ⋯ NCT03677778.

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.
