Antenatal Care: A Comparative Review of Guidelines.

Importance: Antenatal care plays a crucial role in safely monitoring and ensuring the well-being of both the mother and the fetus during pregnancy, ultimately leading to the best possible perinatal outcomes.

Objective: The aim of this study was to review and compare the most recently published guidelines on antenatal care.

Evidence acquisition: A descriptive review of guidelines from the National Institute for Health and Care Excellence, the Public Health Agency of Canada, the World Health Organization, and the Royal Australian and New Zealand College of Obstetricians and Gynaecologists regarding antenatal care was conducted.

Results: There is a consensus among the reviewed guidelines regarding the necessary appointments during the antenatal period, the proper timing for induction of labor, the number and frequency of laboratory examinations for the assessment of mother's well-being, and management strategies for common physiological problems during pregnancy, such as nausea and vomiting, heartburn, pelvic pain, leg cramps, and symptomatic vaginal discharge. In addition, special consideration should be given for mental health issues and timely referral to a specialist, reassurance of complete maternal vaccination, counseling for safe use of medical agents, and advice for cessation of substance, alcohol, and tobacco use during pregnancy. Controversy surrounds clinical evaluation during the antenatal period, particularly when it comes to the routine use of an oral glucose tolerance test and symphysis-fundal height measurement for assessing fetal growth, whereas routine cardiotocography and fetal movement counting are suggested practices only by Royal Australian and New Zealand College of Obstetricians and Gynaecologists. Of note, recommendations on nutritional interventions and supplementation are offered only by Public Health Agency of Canada and World Health Organization, with some minor discrepancies in the optimal dosage.

Conclusions: Antenatal care remains a critical factor in achieving positive outcomes, but there are variations depending on the socioeconomic status of each country. Therefore, the establishment of consistent international protocols for optimal antenatal care is of utmost importance. This can help provide safe guidance for healthcare providers and, consequently, improve both maternal and fetal outcomes.
