A woman who is pregnant encounters various dangers throughout her pregnancy, labor, and delivery. Any unforeseen or unpredicted medical or obstetric issue associated with pregnancy that presents an actual or possible risk to the health or welfare of the mother or baby is considered a high-risk pregnancy. Approximately 20 million women worldwide experience high-risk pregnancies, with over 800 deaths occurring each day due to perinatal issues. In developing nations, maternal morbidity and mortality rates are still remarkably high, as many women suffer from both severe and ongoing obstetric complications. Women who survive serious acute maternal health issues, or near misses, share several similarities with circumstances that lead to maternal fatalities, especially concerning risk factors. Inadequate care can greatly contribute to rising rates of maternal morbidity and mortality. Moreover, the frequency of these incidents within a community often mirrors the quality of maternity care available to expectant mothers. The maternity nurse plays an essential role in improving maternal outcomes by identifying, anticipating, and reporting early warning signs of a mother's potential decline. In developing countries, roughly 75% of women with obstetric complications reach tertiary care in critical condition. Consequently, enhancing nurses' knowledge and practices is vital for providing effective care for high-risk pregnancies and maternal near-miss situations. This review article examines the dedication and commitment of nurses to deepen their understanding and practices related to high-risk pregnancies and maternal near-miss cases, with the ultimate goal of raising the standard of care for pregnant women.
