The wound healing process following acute inflammation after surgery is impaired in diabetes. Altered macrophage functions are linked to delayed tissue repair and pain development in diabetes. Although peroxisome proliferator-activated receptor (PPAR)-γ agonists are used to treat diabetes, their postoperative analgesic effects in diabetes have not been evaluated. ⋯ In diabetes, exogenous administration of RvD1 is essential for PPARγ-mediated analgesia during development of postincisional pain. Resolution of inflammation accelerated by RvD1 might promote PPARγ-mediated macrophage polarization to the M2 phenotype.

An Expedited Care Pathway with Ambulatory Brachial Plexus Analgesia Is a Cost-effective Alternative to Standard Inpatient Care after Complex Arthroscopic Elbow Surgery: A Randomized, Single-blinded Study.
Common standard practice after complex arthroscopic elbow surgery includes hospital admission for 72 h. The authors hypothesized that an expedited care pathway, with 24 h of hospital admission and ambulatory brachial plexus analgesia and continuous passive motion at home, results in equivalent elbow range of motion (ROM) 2 weeks after surgery compared with standard 72-h hospital admission. ⋯ The results suggest that an expedited care pathway with early hospital discharge followed by ambulatory brachial plexus analgesia and continuous passive motion at home is a cost-effective alternative to 72 h of hospital admission after complex arthroscopic elbow surgery.

Psychiatric Disorders and Psychopharmacologic Treatment as Risk Factors in Elective Fast-track Total Hip and Knee Arthroplasty.
Psychiatric disorder (PsD) is rarely considered when evaluating perioperative risk factors. Studies on PsD are often limited by use of administrative coding, incomplete follow-up, and lack of preoperative data on psychopharmacological treatment. ⋯ Psychopharmacologically treated PsD is a risk factor for postoperative morbidity after fast-track arthroplasty, regardless of treatment type. This may be due to PsD per se and/or drug-related side effects.

Randomized Controlled Trial
Nitrous Oxide and Serious Long-term Morbidity and Mortality in the Evaluation of Nitrous Oxide in the Gas Mixture for Anaesthesia (ENIGMA)-II Trial.
The Evaluation of Nitrous Oxide in the Gas Mixture for Anaesthesia (ENIGMA)-II trial randomly assigned 7,112 noncardiac surgery patients at risk of perioperative cardiovascular events to 70% N2O or 70% N2 groups. The aim of this follow-up study was to determine the effect of nitrous oxide on a composite primary outcome of death and major cardiovascular events at 1 yr after surgery. ⋯ These results support the long-term safety of nitrous oxide administration in noncardiac surgical patients with known or suspected cardiovascular disease.
