ReviewCognitive Aids in Obstetric Units: Design, Implementation, and Use.
Obstetrics has unique considerations for high stakes and dynamic clinical care of ≥2 patients. Obstetric crisis situations require efficient and coordinated responses from the entire multidisciplinary team. Actions that teams perform, or omit, can strongly impact peripartum and perinatal outcomes. ⋯ However, they are intended to be combined with clinician judgment and training, not as absolute or exhaustive standards of care for patient management. There is simulation-based evidence showing efficacy of cognitive aids for enhancing appropriate team management during crises, especially with a reader role, with growing literature supporting use in obstetric and nonobstetric clinical settings when combined with local customization and implementation efforts. The purpose of this article is to summarize current understanding and available resources for cognitive aid design, implementation, and use in obstetrics and to highlight existing gaps that can stimulate further enhancement in this field.

ReviewPerioperative Anemia: Prevention, Diagnosis, and Management Throughout the Spectrum of Perioperative Care.
Anemia is common in the perioperative period and is associated with poor patient outcomes. Remarkably, anemia is frequently ignored until hemoglobin levels drop low enough to warrant a red blood cell transfusion. This simplified transfusion-based approach has unfortunately shifted clinical focus away from strategies to adequately prevent, diagnose, and treat anemia through direct management of the underlying cause(s). ⋯ Rather, anemia must be actively addressed throughout the perioperative spectrum of patient care. This article provides practical information regarding the implementation of anemia management strategies in surgical patients throughout the perioperative period. This includes evidence-based recommendations for the prevention, diagnosis, and treatment of anemia, including the utility of iron supplementation and erythropoiesis-stimulating agents (ESAs).

Clinical TrialPreoperative Vancomycin Administration for Surgical Site Prophylaxis: Plasma and Soft-Tissue Concentrations in Pediatric Neurosurgical and Orthopedic Patients.
Vancomycin is used for antibiotic prophylaxis in pediatric surgical patients without a complete understanding of plasma and soft-tissue pharmacokinetics. Guidelines recommend incision within 60 minutes after administration; however, tissue vancomycin concentrations at that early time may not be therapeutic. We conducted a study of plasma and skin concentrations in pediatric neurosurgical and orthopedic patients to characterize intraoperative vancomycin pharmacokinetics. ⋯ Skin vancomycin concentrations immediately after a preoperative dose are relatively low compared with concentrations at the end of surgery. It may be advisable to extend the time between dose and incision if higher skin concentrations are desired at the start of surgery.

Randomized Controlled TrialEffects of Inhaled Iloprost on Lung Mechanics and Myocardial Function During One-Lung Ventilation in Chronic Obstructive Pulmonary Disease Patients Combined With Poor Lung Oxygenation.
The ventilation/perfusion mismatch in chronic obstructive pulmonary disease (COPD) patients can exacerbate cardiac function as well as pulmonary oxygenation. We hypothesized that inhaled iloprost can ameliorate pulmonary oxygenation with lung mechanics and myocardial function during one-lung ventilation (OLV) in COPD patients combined with poor lung oxygenation. ⋯ Inhaled iloprost improved pulmonary oxygenation, lung mechanics, and cardiac function simultaneously during OLV in COPD patients with poor lung oxygenation.
