Guideline No. 441: Antenatal Fetal Health Surveillance
Kirsten M Niles1, Venu Jain2, Cynthia Chan3
1Surrey, British Columbia.
Summary
This guideline provides recommendations for antenatal fetal health surveillance (FHS) to detect fetal decompensation and prevent adverse perinatal outcomes. Optimizing FHS protocols can improve outcomes and reduce harm for high-risk pregnancies.
Area of Science:
- Obstetrics and Gynecology
- Maternal-Fetal Medicine
- Perinatal Medicine
Background:
- Current evidence on antenatal fetal health surveillance (FHS) is summarized to guide clinical practice.
- Identifies pregnant individuals at risk for antenatal fetal decompensation.
Framework:
- Utilizes basic and advanced antenatal testing modalities tailored to individual risk factors.
- Aims to detect perinatal risk factors and potential fetal decompensation early.
Implementation:
- Facilitates timely intervention to prevent perinatal morbidity and mortality.
- Recommendations are based on the Grading of Recommendations Assessment, Development and Evaluation (GRADE) approach.
Implications:
- Optimized FHS protocols can improve perinatal outcomes and reduce harm.
- Addresses potential harms of FHS, including unnecessary interventions and increased healthcare resource utilization.

Fetal Circulation
1.1K
Fetal circulation is a unique system that facilitates the exchange of gases, nutrients, and waste products between the developing fetus and the mother. This intricate process takes place through a special organ called the placenta.
Two umbilical arteries transport blood from the fetus to the placenta. At the placenta, the blood absorbs oxygen and nutrients while simultaneously eliminating waste products. This oxygen-enriched and nutrient-rich blood then returns to the fetus through one...

Teratogenicity
2.5K
The ability of a drug to produce structural deformations and functional abnormalities in the developing embryo or the fetus is called teratogenicity, and the drug producing this effect is known as a teratogen. Teratogenic effects include stillbirth, miscarriage, intrauterine growth restriction, and neurocognitive delay. A teratogen may affect the embryo at different stages of development, which is important in determining the type and extent of the damage. During blastocyst formation, the early...

Principles of Disease Surveillance
122
Disease surveillance is the systematic collection, analysis, and interpretation of health data essential to the planning, implementation, and evaluation of public health practice. This process integrates data dissemination to entities responsible for preventing and controlling disease, injury, and disability. Surveillance systems provide crucial information for action, helping public health authorities make informed decisions to manage and prevent outbreaks, ensure public safety, optimize...

Healthcare Associated Infections II: Preventive Measures
2.7K
Essential infection prevention measures are based on the knowledge of the infection chain, the modes of transmission in healthcare settings, and the use of the best practices in all healthcare settings. Compulsory public reporting of healthcare-associated infection rates is needed to allow individuals and the community to make informed choices regarding selecting a healthcare facility.
