Review Meta Analysis
Effects of Volatile Anesthetics on Mortality and Postoperative Pulmonary and Other Complications in Patients Undergoing Surgery: A Systematic Review and Meta-analysis.
It is not known whether modern volatile anesthetics are associated with less mortality and postoperative pulmonary or other complications in patients undergoing general anesthesia for surgery. ⋯ In cardiac, but not in noncardiac, surgery, when compared to total IV anesthesia, general anesthesia with volatile anesthetics was associated with major benefits in outcome, including reduced mortality, as well as lower incidence of pulmonary and other complications. Further studies are warranted to address the impact of volatile anesthetics on outcome in noncardiac surgery.

Randomized Controlled Trial Comparative Study
Postoperative Urinary Catheterization Thresholds of 500 versus 800 ml after Fast-track Total Hip and Knee Arthroplasty: A Randomized, Open-label, Controlled Trial.
No evidence-based threshold exists for postoperative urinary bladder catheterization. The authors hypothesized that a catheterization threshold of 800 ml was superior to 500 ml in reducing postoperative urinary catheterization and urological complications after fast-track total hip arthroplasty (THA) and total knee arthroplasty (TKA). ⋯ In fast-track THA and TKA, a catheterization threshold of 800 ml significantly reduced the need for postoperative urinary catheterization, without increasing urological complications. This large randomized, controlled trial may serve as a basis for evidence-based guidelines on perioperative urinary bladder management.

Randomized Controlled Trial Multicenter Study
Liposome Bupivacaine Femoral Nerve Block for Postsurgical Analgesia after Total Knee Arthroplasty.
The authors evaluated the efficacy of liposome bupivacaine in a femoral nerve block (FNB) after total knee arthroplasty. ⋯ FNB with liposome bupivacaine (266 mg) resulted in modestly lower pain scores and reduced opioid requirements after surgery, with an adverse event profile similar to placebo.

Due to an increase in implantable device-related anesthesia pain medicine claims, the authors investigated anesthesia liability associated with these devices. ⋯ Half of IDDS maintenance claims were associated with death or permanent severe injury, most commonly from medication errors or failure to recognize progressive neurologic deterioration. Practitioners implanting or managing devices for chronic pain should exercise caution in these areas to minimize patient harm.
