Clinical characteristics of women captured by extending the definition of severe postpartum haemorrhage with 'refractoriness to treatment': a cohort study
Background: The absence of a uniform and clinically relevant definition of severe postpartum haemorrhage
hampers comparative studies and optimization of clinical management. The concept of persistent postpartum
haemorrhage, based on refractoriness to initial first-line treatment, was proposed as an alternative to common
definitions that are either based on estimations of blood loss or transfused units of packed red blood cells
(RBC). We compared characteristics and outcomes of women with severe postpartum haemorrhage captured
by these three types of definitions.
Methods: In this large retrospective cohort study in 61 hospitals in the Netherlands we included 1391 consecutive
women with postpartum haemorrhage who received either â„4 units of RBC or a multicomponent transfusion. Clinical
characteristics and outcomes of women with severe postpartum haemorrhage defined as persistent postpartum
haemorrhage were compared to definitions based on estimated blood loss or transfused units of RBC within 24 h
following birth. Adverse maternal outcome was a composite of maternal mortality, hysterectomy, arterial embolisation
and intensive care unit admission.
Results: One thousand two hundred sixty out of 1391 women (90.6%) with postpartum haemorrhage fulfilled the
definition of persistent postpartum haemorrhage. The majority, 820/1260 (65.1%), fulfilled this definition within 1 h
following birth, compared to 819/1391 (58.7%) applying the definition of â„1 L blood loss and 37/845 (4.4%) applying
the definition of â„4 units of RBC. The definition persistent postpartum haemorrhage captured 430/471 adverse maternal
outcomes (91.3%), compared to 471/471 (100%) for â„1 L blood loss and 383/471 (81.3%) for â„4 units of RBC. Persistent
postpartum haemorrhage did not capture all adverse outcomes because of missing data on timing of initial, first-line
treatment.
Conclusion: The definition persistent postpartum haemo
Strategies and tactics in deductive reasoning
This book offers one of the first systematic attempts to discuss the role of strategies for deductive reasoning. After a review of the different proposals, we introduce an operational definition of strategies: A strategy is a set of explicit, systematic cognitive processes, which are used when solving a deduction problem in order to simplify the problem or to come as quickly/easily as possible to a conclusion. A strategy is composed of smaller steps, which we call tactics. These tactics are largely unconscious. With this definition, one can discuss much easier the different observations mentioned in the book. In the last part of the chapter, we discuss more extensively the relation between the mental model theory and strategies
Autologous Fat Transfer: An Aesthetic and Functional Refinement for Parotidectomy
Parotidectomy is a surgical procedure associated to functional (Freyâs syndrome) as well as aesthetic (facial asymmetry) complications that can be very disturbing for the patient. Several procedures have been described to primarily avoid or secondarily reconstruct the facial defect and treat the neurological iatrogenic syndrome.
Autologous fat transfer was primarily used in 10 cases to avoid such complications. It is an easy technique widely used in cosmetic and reconstructive surgery. This technique gives very satisfying long-term results on the cosmetic as well as on the physiological point of view
