Doğum İndüksiyonunda Bașarıyı Etkileyen Faktörler ve Doğum İndüksiyonu Yöntemleri

Doğum indüksiyonu, spontan doğum eylemi bașlamadan önce vajinal doğumu gerçekleștirmek amacıyla uterin kontraksiyonların iyatrojenik olarak uyarılmasıdır. Genel olarak, doğum indüksiyonu kararı anne veya fetüs için doğumun hemen gerçekleștirilmesinin yararı gebeliğin devamının getireceği risklerden fazla ise verilmelidir. Son zamanlarda, dünyada doğum indüksiyonunun kullanımı, özellikle de elektif doğum indüksiyonu, belirgin olarak artıș göstermiștir ve aslında ciddi morbidite riskini de beraberinde getirmektedir. Doğum indüksiyonu yapılan gebelerin üçte ikisinden azı ileri bir girișim gerektirmeden doğurmaktadır ve indüksiyon ile operatif doğum ve sezaryen oranları, postpartum kanama miktarı, kan transfüzyonu gereksinimi, uterotonik ajanların kullanımı ve histerektomi olasılığı artabilmektedir. Bu nedenle de, doğum indüksiyonunun bașarılı olup olmayacağının öngörülmesi, bașarılı bir doğum indüksiyonunu etkileyen faktörlerin ve doğum indüksiyonu yöntemlerinin iyi bilinmesi morbiditeyi en aza indirgemek açısından önem tașımaktadır. Bu derlemede, doğum indüksiyonu bașarısını etkileyen faktörlerin ve doğum indüksiyonu yöntemlerinin son rehberler ıșığında yeniden gözden geçirilmesi amaçlanmıștır

Doğum İndüksiyonunda Bașarıyı Etkileyen Faktörler ve Doğum İndüksiyonu Yöntemleri

Induction of labor is the iatrogenic stimulation of uterine contractions before the onset of spontaneous labor to achieve vaginal delivery. It must be generally decided when the benefits of immediate delivery outweigh the risks of continuing the pregnancy for fetal and maternal health. In the recent years, the rate of elective induction of labour has risen dramatically throughout the world and, in fact, brings significant morbidity for both the mother and the fetus. Fewer than two thirds of women in whom labour induction is performed give birth without further interventions and, labour induction increases operative vaginal delivery and cesarean section rates, the possibility of postpartum bleeding, the need for blood transfusions, use of uterotonic agents and hysterectomy. Thus, predicting the success of labour induction and gaining precise knowledge about methods of labour induction is important in minimising associated morbidity. This review focuses on factors associated with the success of labour induction and methods of labour induction in light of recent guides
