Kuzu modeli için insan yenidoğan boyutunda karşılaştırılabilir ve invaziv hemodinamik değişkenler ölçmek kolay araçları sağlar. Fetal/yenidoğan kuzu model zengin transitioning dolaşım yanı sıra yeni doğmuş pulmoner ve kardiyovasküler Fizyoloji anlamak için katkıda bulunan bir çok değerli araştırma aracı olmuştur. Erken Doğum en iyi havalandırma stratejileri kuzular13,14,21, duktal bir kalıcı pul...

Perinatal asfiksili yaklaşık 1.000 terim doğumda 4 Amerika Birleşik Devletleri'nde ortaya çıkar ve 4 milyon yenidoğan ölüm dünya çapında1,2yaklaşık % 25 sorumludur. Fetus'ın doğal gelişim çeşitli uyarlamalar Doğum sırasında ve Doğum akciğerlerde gaz değişimi organı olarak plasenta rol alırken extrauterine ortamına içi-kesintisiz geçiş için izin vermek için yer almalıdır. Herhangi bir hata yeterince geçiş doğumda daha fazla Yenidoğan Reanimasyon çabaları ödün vermez. Fetal akciğer izni eksik veya gecikmiş3,4ve bir kalıcı yüksek pulmoner vasküler direnç (PVR)5 etki en kalır havalandırma etkinliği neden koşullar olduğunda örnekleri resüsitasyon mahallelerini yeni doğan6önemli müdahale. Buna ek olarak, hemen göbek kordonu ve düşük direnç plasenta kaldırılması sıkma miyokard disfonksiyonu7,8neden olabilir kardiyak çıkış ani değişikliklere yol açabilir.
Agresif resüsitasyon (gerek göğüs sıkıştırma ve/veya yönetim epinefrin)1,9seyrek gereksinimini nedeniyle büyük randomize klinik çalışmalar mevcut desteklemek için güçlü kanıt eksikliği var Neonatal resüsitasyon programı (Konumundan) yönergeleri. Neonatal resüsitasyon birçok translasyonel araştırma çalışmaları yeterli geçiş tasvir başarısız postnatal hayvan modelleri (özellikle domuz yavruları) kullanarak yapılmaktadır fetal dolaşım ve akciğerler teslimi için yenidoğan doğal sıvı dolu Oda. Fetal dolaşım yenidoğan dolaşım için geçiş ile ilgili benzersiz zorluklar göz önüne alındığında, perinatal mahallelerini kardiyak arrest fetal kuzu modeli yeni doğan Reanimasyon Fizyoloji eğitim idealdir.
Joseph Barcroft tarafından çalışmalar fetal üzerinde kuzular, 1930'lardan, gibi erken fetal ve neonatal Fizyoloji10için temeli atıldı. 20inci yüzyılın ikinci yarısında modelleri üzerinde fetal Geoffrey Dawes yenilikçi ve titiz deneyler kuzu ve daha sonra bu Abraham Rudolph tarafından muazzam kardiyovasküler ve pulmoner Fizyoloji fetus bilgisine katkıda bulunmuştur 11 , 12. son yıllarda çalışmalar fetal/yenidoğan kuzu modellerde daha iyi havalandırma hemodinami13,14, etkisini oksijenasyonu PVR15,16, etkilerini anlamak sağlanan 7,17sıkma kablosu sırasında oluşan dolaşım değişiklikleri yanı sıra. Son olarak, son bir yıl içinde yeni doğmuş kuzu resüsitasyon18,19,20sırasında hemodinamik etkileri çalışmaya yeni bir model olarak hizmet vermiştir. Ne hakkında adım adım bir anlatı bir kuzu deneme yanı sıra cerrahi cihazların ayrıntılı bir açıklamasını yürütülmesinde ilgilenmektedir ve deneysel yöntemler sunulacaktır.

the perinatal asphyxiated lamb model: a model for newborn resuscitation

Doğum boğulma her yıl yaklaşık bir milyon ölüm için dünya çapında hesapları ve erken neonatal morbidite ve mortalite birincil nedenlerinden biridir. Öngörülemeyen ihtiyacınız için kapsamlı resüsitasyon randomize klinik çalışmalar sayesinde seyrek ve sık sık yürütülmesi konusunda zorluklar verilen mevcut neonatal resüsitasyon kurallar birçok açıdan tartışmalı kalır. Gerçekten fizyolojik değişiklikleri yansıtacak şekilde başarısız manken modelleri veya bu onların akciğer sıvı temizlendiğini ve bu fetal geçiş için yenidoğan dolaşımını tamamlamış piglet modellerin çoğu çalışmalar neonatal resüsitasyon kaynaklanıyor. Mevcut iletişim kuralı perinatal mahallelerini fetal kuzu modeli oluşturma konusunda ayrıntılı adım adım açıklamasını sağlar. Önerilen model transitioning dolaşım ve hangi insan yenidoğan dır takip taklit eder ve, bu nedenle, yeni doğan Fizyoloji eğitim için mükemmel bir hayvan model sıvı dolu akciğerler vardır. Kuzu deneyler için önemli bir sınırlama daha yüksek ilişkili maliyetidir.

Araçları fetal Kuzuların, ardından hemodinamik değişkenler kaydedilen (Şekil 3 ve Şekil 4), daha sonra analiz ve (Şekil 5) yorumlanır. Sık kan örnekleri toplanır ve Şekil 6 pH ve PaCO2 veri birinden deneyler göstermektedir. Bazen, kateterler veya akış sondaları düzgün çalışmayabilir veya yerinden ve veri, bu nedenle, değil toplanan ve <...
