Introduction: The aim of our study was to evaluate the distribution of indications of termination of pregnancies in the 2,5-year period between the period May 2016-December 2018 at the Obstetric Clinic of Trakya University Medical Faculty and to compare the efficacy of 400 μg misoprostol administered intravaginally in every 4 hours to 600 μg misoprostol administered intravaginally in every 24 hours for pregnancy termination.
Methods: In our retrospective cohort study, indications for termination of pregnancies over 10 (ten) weeks and efficiency of misoprostol treatment protocols were investigated. A total of 128 women were included in the study between ages 18 and 45 that were hospitalized for pregnancy termination over 10 (ten) weeks. In 63 patients (Group 1), 400 μg misoprostol was administered intravaginally 4 hours apart. In 65 patients (Group 2), 600 μg misoprostol was administered intravaginally 24 hours apart. The dose was repeated until adequate uterine contraction was achieved in both groups. The method was considered to be unsuccessful in cases where abortion / delivery was not achieved after 48 hours.
Results: The termination indications of 128 patients in our study were determined. Indications for termination of pregnancy were: Missed Abort and IUGR (in utero mort fetus) 32 (%25), central nervous system anomalies 30(%23,4), anhydramnios 28(%21,8), chromosomal anomalies 11(%8,5), cardiac anomalies 7(%5,4), multiple system anomalies 6(%4,6), musculoskeletal anomalies 5(%3,9), gastrointestinal and genitourinary system anomalies 5 (%3,9). Group 1 abortus rate was %90,4 in 48 hours. Group 2 success rate was %92,3 in 48 hours.

Conclusion: Obstetric ultrasonography examination is the most important method in the diagnosis of fetal structural anomalies. When fetal anomalies are evaluated, central nervous system anomalies constitute the largest group in termination cases. In our hospital, the misoprostol protocols were found to be effective and reliable. But no consensus yet on what an effective and reliable route of administration and dosage should be for misoprostol.

Amaç: Çalışmamızın amacı Trakya Üniversitesi Tıp Fakültesi Doğum Kliniğinde Mayıs 2016 –Aralık  2018 tarihleri arasındaki 2,5 yıllık zaman aralığında terminasyon yapılan gebeliklerin endikasyonlarının dağılımını değerlendirmek ve 10 (on) hafta üzeri gebelik sonlandırmasında dört saatte bir intravajinal ve yirmi dört saatte bir vajinal yolla uygulanan sırasıyla 400 μg ve 600 μg mizoprostolün etkinliğini karşılaştırmak. 

Gereç ve Yöntem:Retrospektif dosya incelemesi şeklinde planlanan çalışmamızda kliniğimizde terminasyon kararı verilen 10 (on) hafta üzeri gebeliklerin sonlandırılma endikasyonları ve uygulanmakta olan mizoprostol tedavi protokollerinin etkinliği incelendi. 18-45 yaş arası, 10 (on) hafta ve üzeri olan gebeliklerin sonlandırılmasının planlandığı toplam 128 kadının dosyası değerlendirildi. 63 hastaya (Grup 1) 4 saat ara ile tekrarlanan 400 μg vajinal yolla mizoprostol uygulandı. 65 hastaya (Grup 2) 24 saat ara ile tekrarlanan 600 μg vajinal yolla mizoprostol uygulandı. Her iki grupta yeterli uterin kontraksiyon elde edilene kadar doz tekrarlanıp 48 saat sonrasında abortus/doğum gerçekleşmemesi halinde yöntem başarısız olarak kabul edildi. 

 

Bulgular: Çalışmamızda termine edilen 128 hastanın terminasyon endikasyonları belirlendi. Gebelik terminasyon endikasyonları: Missed Abort ve IUGR (in utero mort fetus) 32(%25), santral sinir sistemi anomalileri 30(%23,4), anhidramniyoz 28(%21,8), kromozal anomaliler 11(%8,5), kardiyak anomaliler 7(%5,4), çoklu sistem anomalileri 6(%4,6), kas iskelet anomalileri 5 (%3,9), gastrointestinal ve genitoüriner sistem anomalileri 5(%3,9), teratojen ilaç kullanımı ve radyasyona maruz kalma 4(%3,1) bulundu.  Grup 1 olgularda 48 saatte abortus oranı (%90.4) idi. Grup 2 olgularda 48 saatte başarı oranı ise (%92,3) bulundu.

Sonuç: İlk trimester ve ikinci trimesterde yapılan obstetrik ultrasonografi fetal yapısal anomalilerin tanısında tek yöntemdir. Santral sinir sistemi anomalileri fetal anomaliler içerisinde en büyük grubu oluşturmaktadır. Hastanemizde 10 (on) hafta ve üzeri gebelik sonlandırılmasında kullanılan mizoprostolün etkili ve güvenilir olduğu düşünülmektedir.
