Introduction
Symptoms of fetal hypoxia at 26 weeks of gestation include frequent fetal movements, slowed fetal movements, and disappearance of fetal movements. In the early stage of hypoxia, the fetus may exhibit a stress response due to transient oxygen deficiency. When persistent hypoxia occurs, the fetus's physical activity becomes restricted and movements slow down compared to normal. In cases of acute fetal hypoxia, fetal movements may rapidly cease within a short period.
At 26 weeks of gestation, manifestations of fetal hypoxia mainly include increased fetal movements, slowed fetal movements, and disappearance of fetal movements.
1. Increased fetal movements: Generally, maternal bodies do not exhibit obvious discomfort symptoms when the fetus is experiencing hypoxia; fetal health can only be assessed through monitoring fetal movements. In the early stages of fetal hypoxia, due to transient oxygen deficiency, the fetus may have a stress response, leading to intense fetal activity and noticeably frequent movements.
2. Slowed fetal movements: When fetal hypoxia becomes persistent, the fetus's physical activity becomes restricted, resulting in reduced movement compared to normal. Timely oxygen supplementation is required to alleviate this condition; otherwise, prolonged hypoxia may impair fetal brain development and, in severe cases, lead to fetal distress in utero, causing adverse outcomes.
3. Disappearance of fetal movements: In acute hypoxic events such as umbilical cord torsion or prolapse, fetal movements may rapidly cease within a short period. If the mother fails to detect this promptly and the fetus is not delivered and resuscitated immediately, intrauterine fetal death may occur, potentially endangering the mother's safety as well.
