Postpartum Kanama Tespiti ve Tanı
Özet
Postpartum kanama (PPK), dünya genelinde anne ölümlerinin en önemli ve önlenebilir nedenlerinden biridir. Erken tanı ve etkin tedavi maternal mortaliteyi azaltmada kritik rol oynar. Geleneksel olarak kan kaybı çoğunlukla görsel tahminle değerlendirilmekte, ancak bu yöntem %30–50 oranında yetersiz kalmaktadır. Bu nedenle kantitatif yöntemler (gravimetri, volümetri, fotometri, kolorimetri, yapay zekâ tabanlı analizler) klinik uygulamalara entegre edilmiştir. Gravimetri, kanlı materyallerin tartılmasıyla yapılırken; volümetri kalibreli örtüler ve kanisterlerle doğrudan hacim ölçümünü sağlar. Fotometri ve kolorimetri daha doğru olsa da maliyetli ve erişilebilirliği düşüktür. Yapay zekâ destekli sistemler hızlı ve objektif sonuç vermektedir. Görsel yardımcı materyaller, eğitim ve farkındalık artırmada önemlidir, ancak tek başına yeterli değildir. Erken tanıda vital bulgular ve özellikle şok indeksi (≥ 0.9–1.0) değerli göstergelerdir. WHO ve FIGO gibi kurumlar, MEOWS gibi erken uyarı sistemlerinin kullanılmasını önermektedir. Erken tanı, multidisipliner ekip yaklaşımı, objektif ölçüm yöntemlerinin rutin entegrasyonu ve vital bulguların dikkatli takibi ile maternal morbidite ve mortalite anlamlı şekilde azaltılabilir.
