• Primaire PPH binnen 24u na de bevalling ~19%

– >500 mL vaginale partus of

– >1000 mL sectio of

– verandering vitale parameters

• met >15 % of HF ≥110 /min, RR ≤85/45 mmHg, Saturatie <95%

– Gravimetric measurement

• Risk assessment (incl. coagulation testing)

– Fibrinogen, platelet count

Tempoh-1 resultaten

• 2011-2013 n=1312 women

– n=463 (35%) developed a combined end point

– n=7 died (0.5%)

• The incidence of a fibrinogen level<2 g/L was 26%

• Low fibrinogen and prolonged aPTT during the first 2 L

PPH were associated with a subsequent composite

adverse outcome

– Median fibrinogen 1.5 g/L [IQR 1.0-1.9] vs. 2.7 g/L [IQR

1.9-3.4]

– Median APTT 39 s [IQR 30-47] vs. 32 s [IQR, 28-36]
