Abstract
Objectives
Stillbirth is an important health problem, and in Mexico, only half of the stillbirths have an explainable cause. The aim of this study was to implement a multidisciplinary workup to identify the etiology and potential risk factors for stillbirth at the Hospital Universitario “Dr. José Eleuterio González”.
Methods
This is a prospective, descriptive, observational study that included stillbirths from the Obstetrics Service from October 1st, 2019 to May 25, 2020. Evaluation strategies included a complete maternal medical history, physical examination of the fetus, and a photographic medical record. For every stillbirth either a prenatal ultrasound, a postnatal x-ray, or a fetal autopsy, were needed. Multiplex Ligation Probe Amplification (MLPA) was performed with an umbilical cord sample.
Results
Thirty-three stillbirths were reported; 21 were included in the analysis. Eleven women (52.3%) had known risk factors for stillbirth, mainly elevated body mass index and diabetes. On physical examination, external birth defects were found in 8 fetuses (38%). X-ray was performed in 14 cases (66%), alterations were detected as a probable etiologic cause just in one. All cases underwent MLPA, which were reported negative. Three cases had criteria for autopsy. Findings were inconclusive to determine etiology.
Conclusions
The best tools for evaluation of stillbirth were the elaboration of clinical history, physical examination, and prenatal ultrasound. Diabetes and obesity were the most frequent risk factors found in our population. These factors are preventable by implementing strategies that lead to better prenatal care.
Significance
Stillbirth is a health problem whose causes are rarely evaluated and explained to the families that go through this situation. To completely explain the causes of stillbirth a complete workup should be performed, where a multidisciplinary participation is needed. Mainly these workups have been performed retrospectively, however we introduce a complete evaluation of stillbirth since the moment of arrival to obstetrics department and performing evaluations for fetal, maternal or combined causes, including genetic testing; detecting key health issues in our population, that can be prevented with an adequate prenatal care.
