Postpartum hemorrhage PPH is the leading cause of maternal death worldwide, accounting for one in four maternal deaths. Despite efforts in public health policy, the what is the causal-relationship of an experiment to a theory of massive PPH has increased in recent years even in first world countries.

In Colombia, PPH is the second leading cause of maternal death. Multiple observational studies have provided evidence about the association between the concentration levels of fibrinogen in blood plasma and the severity of PPH, proposing the systematic use of fibrinogen concentrates as od prophylactic or therapeutic measure in patients with obstetric hemorrhage.

However, the statistical relationship demonstrated in such studies should not necessarily be what are some chemical effects of electric current as a cause-effect relationship. Traditionally, we have used the criteria postulated by Sir Arthur Bradford Hill to establish a causal relationship. Therefore, the most pragmatic way to evaluate a possible causal relationship is through a randomized placebo-controlled experiment.

Experiments of this kind available to date have methodological deficiencies or have been criticized for internal validity. As a result, the statistical relationship association between low levels of fibrinogen and PPH cannot be certainly interpreted as a cause-effect relationship and the use of fibrinogen concentrates may only be justified in the expdriment of new clinical trials. La hemorragia posparto HPP es la primera causa de muerte materna en el mundo, siendo responsable de una de causal-realtionship muertes maternas.

En Colombia, la HPP es la segunda causa de muerte materna. Sin embargo, la relación estadística demostrada en este tipo de estudios no necesariamente se debe interpretar como una relación causa-efecto. Los experimentos de esto tipo disponibles a la fecha poseen deficiencias metodológicas o se ha criticado su validez interna. Postpartum hemorrhage PPH is the leading cause of maternal death in the world defined as maternal death during gestation, delivery or during the first 42 days after birth.

PPH along with hypertensive disorders of pregnancy and maternal sepsis are the cause of more than half of the maternal deaths in the world. In Colombia, regional analyses of deaths from PPH have causal-relationshup some aspects that are likely to have a favorable impact on the incidence of maternal mortality due to PPH, for example, the implementation of active management of labor, early diagnosis and aggressive treatment of shock and resuscitation.

These concentrations increase progressively during pregnancy reaching their highest level in the third trimester. For this reason it has been proposed that tranexamic acid a synthetic derivative of lysine through its antifibrinolytic action may reduce the risk of PPH. The criteria postulated in by Sir Austin Bradford Hill have been used traditionally to establish a what is the causal-relationship of an experiment to a theory relationship: strength of association, temporality, consistency, theoretical plausibility, coherency, specificity, what you mean by linear function relationship, experimental evidence, and analogy.

In a systematic review, which what is the causal-relationship of an experiment to a theory six experimental studies and studied a total of non-obstetric patients, it was found that the administration of fibrinogen concentrate decreased the need for allogeneic transfusion, although all the studies analyzed had methodological deficiencies. The need for transfusion from inclusion to study and up to 42 days postpartum was In light of the evidence accumulated in experimental studies, the cause-effect relationship between plasma fibrinogen concentration and the incidence or severity of PPH cannot yet be established or dismissed.

For the time being, it can be theorized that blood fibrinogen levels could be lowered as a consequence of the severity of bleeding and as such could represent an objective measure of the magnitude of bleeding. In conclusion, the statistical relationship association between low levels of fibrinogen and PPH can not be certainly interpreted as a cause-effect relationship in which the natural conclusion would be the widespread and systematic use of fibrinogen concentrates as a prophylactic or therapeutic measure in patients with obstetric hemorrhage.

Possibly the use of such interventions would only be justified in the context of new clinical trials.
