ReviewNational and International Guidelines for Patient Blood Management in Obstetrics: A Qualitative Review.
In developed countries, rates of postpartum hemorrhage (PPH) requiring transfusion have been increasing. As a result, anesthesiologists are being increasingly called upon to assist with the management of patients with severe PPH. First responders, including anesthesiologists, may adopt Patient Blood Management (PBM) recommendations of national societies or other agencies. ⋯ On the basis of our review, we identified important differences in national and international societies' recommendations for transfusion and PBM. In the light of PBM advances in the nonobstetric setting, obstetric societies should determine the applicability of these recommendations in the obstetric setting. Partnerships among medical, obstetric, and anesthetic societies may also help standardize transfusion and PBM guidelines in obstetrics.

ReviewUnderstanding Phenotypes of Obstructive Sleep Apnea: Applications in Anesthesia, Surgery, and Perioperative Medicine.
Obstructive sleep apnea (OSA) is a prevalent sleep-disordered breathing with potential long-term major neurocognitive and cardiovascular sequelae. The pathophysiology of OSA varies between individuals and is composed of different underlying mechanisms. Several components including the upper airway anatomy, effectiveness of the upper airway dilator muscles such as the genioglossus, arousal threshold of the individual, and inherent stability of the respiratory control system determine the pathogenesis of OSA. ⋯ In this review, the clinically relevant endotypes and phenotypes of OSA are described. Continuous positive airway pressure (CPAP) therapy is the treatment of choice for most patients with OSA but tolerance and adherence can be a problem. Patient-centered individualized approaches to OSA management will be the focus of future research into developing potential treatment options that will help decrease the disease burden and improve treatment effectiveness.

Review Practice GuidelineConsensus Bundle on Prevention of Surgical Site Infections After Major Gynecologic Surgery.
Surgical site infections are the most common complication of surgery in the United States. Of surgeries in women of reproductive age, hysterectomy is one of the most frequently performed, second only to cesarean birth. Therefore, prevention of surgical site infections in women undergoing gynecologic surgery is an ideal topic for a patient safety bundle. ⋯ The bundle is organized into four domains: Readiness, Recognition and Prevention, Response, and Reporting and Systems Learning. In addition to recommendations for practice, each of the domains stresses communication and teamwork between all members of the surgical team. Although the bundle components are designed to be adaptable to work in a variety of clinical settings, standardization within institutions is encouraged.

ReviewAnesthetic Considerations for Patients With Congenital Central Hypoventilation Syndrome: A Systematic Review of the Literature.
Congenital central hypoventilation syndrome (CCHS) is a form of sleep-disordered breathing characterized by a diminished drive to breathe during sleep, despite progressive hypercapnia and hypoxia. The condition results from mutations in the paired-like homeobox 2B (PHOX2B) gene. The aim of this review was to conduct a systematic search of the current data on CCHS as it relates to perioperative considerations and to discuss the classification, prevalence, pathophysiology, presentation, genetics, and management of the condition. ⋯ There appeared to be few postoperative complications in patients with known CCHS. Anesthesiologists need to be aware of undiagnosed late-onset CCHS and include this condition in the differential diagnosis of patients with unexplained postoperative respiratory depression. Anesthetic techniques should minimize the use of agents that further depress respiration postprocedure and ensure adequate monitoring to detect postoperative apneas.

Sporadic Zika virus infections had only occurred in Africa and Asia until an outbreak in Micronesia (Oceania) in 2007. In 2013 to 2014, several outer Pacific Islands reported local outbreaks. Soon thereafter, the virus was likely introduced in Brazil from competing athletes from French Polynesia and other countries that participated in a competition there. ⋯ In this report, we review the potentially devastating effects of Zika virus infection during pregnancy and its implication in cases of Guillain-Barre syndrome in adults. Furthermore, we urge hospital-based clinicians and transfusion medicine specialists to implement perisurgical patient blood management strategies to avoid blood component transfusions with their potential risks of emerging pathogens, illustrated here by the Zika virus. Ultimately, this current global threat, as described by the World Health Organization, will inevitably be followed by future outbreaks of other bloodborne pathogens; the principles and practices of perioperative patient blood management will reduce the risks from not only known, but also unknown risks of blood transfusion for our patients.
