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.

Observational StudyInfluence of inpatient opioid consumption on persistent use following total knee arthroplasty.
Total knee arthroplasty (TKA) is associated with a high incidence of continued opioid use beyond the expected period of recovery. The aim of this study was to determine the influence of inpatient opioid consumption on the development of persistent use. ⋯ Larger amounts of opioid consumed in the hospital following uncomplicated, primary TKA may not be associated with an increased risk of persistent use at 6 weeks among opioid-naïve patients. Patients may have unique risk factors for prolonged opioid use that may not necessarily be apparent in the early postoperative period.

The world needs our science: broadening the research pipeline in anesthesiology.
Anesthesiologists are innovative and adaptable problem solvers. Despite these talents, our field is still working to consistently develop and support the translation of innovation and creativity into productive scientists. This article is focused on opening the discussion on identifying the gaps and move toward developing a sustainable and diverse research pipeline.
