Uterin Atoni Algoritmaları
Özet
Uterin atoni, doğum sonrasında uterusun yeterince kasılamamasıyla ortaya çıkan ve anne hayatını tehdit eden ciddi bir postpartum kanama nedenidir. Postpartum kanamaların en yaygın sebebi uterin atoni olup, anne ölümlerinin de başlıca nedenlerinden biridir. Normal şartlarda, doğumdan hemen sonra uterus kontrakte olarak plasental yataktan oluşan kanamayı durdurur; ancak atoni durumunda bu hayati kontraksiyon mekanizması yetersiz kalır. Atoni risk faktörleri arasında, uterusun aşırı gerilmesine yol açan durumlar, myometriyal disfonksiyon, oksitosin reseptörlerinin duyarsızlaşması, enfeksiyonlar ve bazı anestezik ilaçlar yer alır. Uterin atoninin önlenmesi için doğumun üçüncü evresinde aktif yönetim ve profilaktik oksitosin kullanımı kritik önem taşır. Atoni tanısı, klinik muayenede uterusun gevşek ve yumuşak olarak palpe edilmesiyle konulur. Tedavide ilk adım, kanama durana kadar uygulanan bimanual uterin masaj, kavitedeki pıhtıların temizlenmesi ve oksitosin gibi uterotonik ilaçlardır. Eğer bu tedaviler yetersiz kalırsa, balon tamponad veya cerrahi müdahaleler uygulanabilir. Tüm hastalar için risk değerlendirmesi antenatal dönemde, doğum için başvuruda ve her yeni gelişen durumda yapılmalıdır. Her doğum kliniği oluşabilecek uterin atoni ve postpartum kanama durumunu yönetebilecek donanıma, ekipmana ve eğitimli personele sahip olmalıdır. Uterin atoniye yönelik hazırlıklı olmak, acil durumlarda hızlı ve etkili müdahale edebilmek için hayati önem taşır.
