Abstract

Objective: To describe the clinical and paraclinical characteristics of stillbirth in the thirdtrimester at the National Hospital of Obstetrics and Gynecology. Subjects and methods:Retrospective study on 278 patients with stillbirth from 28 weeksof gestation or more using pre-designed medical records at the National Hospital of Obstetrics and Gynecologyfrom January, 1^st 2022 to December, 31^st 2024. Results: The average rate of stillbirth in the third trimester in the three years from 2022 to 2024 was 0.48%. The average age of the patients was 29.4 ± 5.7 years, most commonly found in the 20–34 age group with a rate of 74.8%. Nulliparous women accounted for 40.6%and history of stillbirth accounted for 9.35%. The average gestational age at the time of stillbirth was 33.9 ± 3.6 weeks, with cases under 38 weeks accounting for 79.1%. Most patients came to the hospital due to absent fetal movements, with a rate of 74.8%. Gestational hypertension accounted for 6.11%, including 2.51% with chronic hypertension and 3.6% with preeclampsia. Regarding blood tests: 99.3% had normal fibrinogen levels, and the rate of anemia with Hemoglobin <110g/l in our study was 13.3%. Conclusion: Third-trimester stillbirth mainly occurred in women of reproductive age and at preterm gestational age. Most patients were admitted due to the absence of fetal movement. Gestational hypertension is one of the key factors associated with third-trimester stillbirth.
