Randomized Controlled Trial
Ferric carboxymaltose with or without phosphate substitution in iron deficiency or iron deficiency anemia before elective surgery - The DeFICIT trial.
Iron deficiency anemia in the perioperative setting is treated predominantly with intravenous iron formulation, of which ferric carboxymaltose may induce hypophosphatemia by modulating fibroblast growth factor 23. ⋯ Co-administration of oral phosphate supplementation to ferric carboxymaltose cannot prevent hypophosphatemia. However, hypophosphatemia occurs in fewer patients. Phosphate co-administration did not impede the treatment of iron deficiency anemia with ferric carboxymaltose.

Randomized Controlled Trial Comparative Study
Volume of intraoperative normal saline versus lactated Ringer's solution on acute kidney injury: A secondary analysis of the SOLAR trial.
Postoperative acute kidney injury (AKI) is common after non-cardiac surgery. Normal saline and lactated Ringer's solution are both used for volume replacement during surgery. Normal saline decreases renal blood flow and causes hyperchloremic acidosis whereas lactated Ringer's does not. The incidence of AKI is similar with modest volumes of each fluid. But it remains unclear whether larger volumes of normal saline provoke AKI. ⋯ While saline administration clearly causes volume-dependent hyperchloremia, we found no evidence to support the theory that large volumes of saline provoke AKI. Therefore, either fluid seems reasonable for intraoperative use.

Cognitive impairment following surgery is a significant complication, affecting multiple neurocognitive domains. The term "perioperative neurocognitive disorders" (PND) is recommended to encompass this entity. Individuals who develop PND are typically older and have increases in serum and brain pro-inflammatory cytokines notwithstanding the type of surgery undergone. ⋯ Bromo-epi-androsterone (BEA) is a potent synthetic analog of DHEA; unlike DHEA, it is non-androgenic, non-anabolic and is an effective modulator of immune dysregulation. In a randomized, placebo-controlled clinical trial, BEA effected significant and sustained decreases in IL-1β, TNFα and IL-6. This article presents BEA as a potential candidate for clinical trials targeting PND and further suggests the use of BEA in elective total hip arthroplasty as a well-documented surgical entity relevant to the management of PND.

Randomized Controlled Trial Observational Study
Ultrasound-assisted middle thoracic epidural catheter placement utilizing the most dorsal sites of bilateral transverse process roots as anatomical landmarks: A cadaveric observational study and a clinical randomized controlled trial.
We developed an innovative method for ultrasound-assisted thoracic epidural catheter placement and assessed its potential to reduce procedural duration for trainees. ⋯ Our novel technique for thoracic epidural catheter placement resulted in expedited needling and enhanced success rates among trainees, although there was no significant difference between total procedure time when using ultrasound guidance and that when using conventional palpation.
