Fibrin polymerization is essential for stable clot formation in trauma, and hypofibrinogenemia reduces hemostasis in trauma. This review considers fibrinogen biology, the changes that fibrinogen undergoes after major trauma, and current evidence for lab testing and treatment. ⋯ Hypofibrinogenemia is an important cause of nonanatomic bleeding in trauma. Despite multiple pathologic causes, the cornerstone of treatment remains fibrinogen replacement with cryoprecipitate or fibrinogen concentrates.

ReviewCoagulation management and transfusion in massive postpartum hemorrhage.
Excessive bleeding during and following childbirth remains one of the leading causes of maternal mortality. ⋯ Factor deficiency is uncommon at the beginning of most etiologies of PPH but will eventually develop from consumption and depletion in the absence of bleeding control. The sensitivity of point-of-care tests for fibrinolysis is too low and may delay treatment, therefore tranexamic acid should be started early at diagnosis even without signs for hyperfibrinolysis. Transfusion management may be initiated empirically, but is best to be guided by laboratory and viscoelastic assay results as soon as possible. Hypofibrinogenemia is well detected by point-of-care tests, thus substitution may be tailored to individual needs, while reliable thresholds for fresh frozen plasma (FFP) and specific components are yet to be defined. In case of factor deficiency, prothrombin complex concentrate or lyophilized plasma allow for a more rapid restoration of coagulation than FFP. If bleeding and hemostasis are under control, a timely anticoagulation may be necessary.

ReviewCurrent concepts in preoperative anemia management in obstetrics.
The purpose of this article is to provide an overview of currently recommended treatment approaches for anemia during pregnancy, with a special focus on iron deficiency and iron deficiency anemia (IDA). ⋯ The treatment of anemia, and more specifically iron deficiency anemia during pregnancy, holds many possibilities for improvement. The fact that the period of risk is known well in advance and thus there is a long optimization phase is per se an ideal prerequisite for the best possible therapy of treatable causes of anemia. Standardization of recommendations and guidelines for screening and treatment of IDA in obstetrics is required for the future. In any case, a multidisciplinary consent is the precondition for a successfully implementation of anemia management in obstetrics to establish an approved algorithm easily enabling detection and treatment of IDA during pregnancy.

Learning from errors has been the main objective of patient safety initiatives for the last decades. The different tools have played a role in the evolution of the safety culture to a nonpunitive system-centered one. The model has shown its limits, and resilience and learning from success have been advocated as the key strategies to deal with healthcare complexity. We intend to review the recent experiences in applying these to learn about patient safety. ⋯ As part of the evolution in patient safety science, learning from errors has its function to open the mindset for the next step: implementing learning strategies beyond the error. The tools for it are ready to be adopted.

ReviewForeign body aspiration in children - being safe and flexible.
Anesthesia for foreign body removal in children can be quite challenging. Even though rigid bronchoscopy is considered the gold standard for foreign body removal, there is increasing evidence for successful foreign body removal using flexible bronchoscopy. This review discusses the recent implications for flexible bronchoscopy for the purpose of foreign body removal and will compare these findings to rigid bronchoscopy. ⋯ Flexible bronchoscopy is a feasible and safe method for removing aspirated foreign bodies in children. In order to improve patient safety during the procedure, it is necessary for a pediatric anesthetist and a pediatric pulmonologist to work closely together. The anesthetist can take care of the administration of the anesthetic and maintenance of the vital functions, and the pulmonologist can carry out a safe and fast bronchoscopy. In the case of foreign body removal by flexible bronchoscopy, the anesthesiological procedure of choice should be general anesthesia with controlled ventilation via a laryngeal mask.
