ReviewCurrent concepts in the evaluation and management of preoperative anemia.
In the past years, patient blood management (PBM) has evolved to improve patient's care and safety. Anemia is one of the most common medical diseases in the world and is an independent risk factor for morbidity and mortality. Iron deficiency is the main cause for anemia and constitutes a potentially preventable condition with a great impact on surgical outcome. However, preoperative anemia management is not yet established in most hospitals. Changing workflows and re-thinking is challenging. Numerous published studies confirmed the positive effect of preoperative anemia diagnosis and treatment recently. ⋯ Since the introduction of PBM programs, important movements towards early detection and therapy of preoperative anemia have been observed. However, preoperative anemia management is not implemented on a large scale as many healthcare professionals are not aware of the most recent findings in the field. Preoperative anemia management, particularly iron supplementation in IDA patients, has proven to be highly effective and has a tremendous effect on patient safety and outcome.

Surgery remains integral to treating solid cancers. However, the surgical stress response, characterized by physiologic perturbation of the adrenergic, inflammatory, and immune systems, may promote procancerous pathways. Anesthetic technique per se may attenuate/enhance these pathways and thereby could be implicated in long-term cancer outcomes. ⋯ The biologic perturbation of the perioperative period, compounded by the effects of anesthetic agents, renders patients with cancer particularly vulnerable to enhanced viability of minimal residual disease, with long-term outcome consequences. However, low level and often conflicting clinical evidence equipoise currently exists with regards to optimal oncoanesthesia techniques. Large, prospective, randomized control trials are urgently needed to inform evidence-based clinical practice guidelines.

ReviewHow new biomarkers aid the anesthetist to detect and prevent perioperative acute kidney injury.
Acute kidney injury (AKI) is underestimated but common in the perioperative setting. Although the association of this syndrome with an increased morbidity and mortality has been well established, little progress has been made in the diagnosis or prevention of AKI in recent years. This is partly due to the late detection of AKI by conventional criteria based of functional biomarkers, serum creatinine, and urine output. In addition, conceptually AKI is now recognized as being part of a continuum, in which preventive intervention is time critical. This review will summarize the current best available evidence and explain why timely perioperative management does have impact on the development of AKI and overall outcomes for patients. ⋯ AKI is a time critical syndrome that requires timely detection and damage biomarkers can help to adjust the perioperative management to prevent further injury.

ReviewAnesthetic management for robotic hysterectomy in obese women.
Obesity is a major health epidemic, with the prevalence reaching ∼40% in the United States in recent years. It is associated with increased risk of hypertension, diabetes, heart disease, stroke, obstructive sleep apnea (OSA), and gynecologic conditions requiring surgery. Those comorbidities, in addition to the physiologic changes associated with obesity, lead to increased risk of perioperative complications. The purpose of this review is to highlight the anesthetic considerations for robotic assisted hysterectomy in obese patients. ⋯ Anesthesia for obese patients undergoing robotic hysterectomy is challenging and must take into consideration the anatomic and physiologic changes associated with obesity.

ReviewAdvances in anesthetic and obstetric management of patients with placenta accreta spectrum.
The incidence of placenta accreta spectrum is increasing and it is a leading cause of peripartum hysterectomy and massive postpartum hemorrhage. The purpose of the present article is to provide a contemporary overview of placenta accreta spectrum pertinent to the obstetric anesthesiologist. ⋯ Accurate diagnosis and early antenatal planning among team members are essential. Obstetric anesthesiologists should be prepared to manage a massive hemorrhage, transfusion, and associated coagulopathy. Increasingly, viscoelastic tests are being used to assess coagulation status and the ability to interpret these results is required to guide the transfusion regimen. Balloon occlusion of the abdominal aorta has been proposed as an intervention that could improve outcomes in women with placenta accreta spectrum, but high-quality safety and efficacy data are lacking.
