356: 97: 1729: 266:. The mechanism of preeclampsia/eclampsia is unknown, but consequences if left untreated can include fetal growth restriction or death, as well as pose medical risks to the mother. Signs and symptoms of preeclampsia can include swelling, protein in the urine, headaches, vomiting, and abnormal labs that assess kidney and liver function, some of which may be considered severe preeclampsia or eclampsia. 247:
in their lungs when they are born, this prevents the pressure in their lungs from falling, which normally facilitates the transition to independent breathing. Since aspiration of meconium can lead to improper oxygenation due to obstruction and carries the potential risk for inflammatory pneumonitis,

If there is too little amniotic fluid around the baby in the uterus, the baby can have trouble moving around in the uterus and its growth and temperature can be impacted. Low amniotic fluid can be caused by placental issues, high gestational blood pressure, some medications, as well as problems with

Instead of referring to "fetal distress", current recommendations hold to look for more specific signs and symptoms, assess them, and take the appropriate steps to remedy the situation through the implementation of intrauterine resuscitation. Traditionally the diagnosis of "fetal distress" led the

Monitoring of the mother and fetus prior to birth is critical to avoid complications after birth. This is often done via electronic fetal heart rate (FHR) monitoring, which helps providers monitor the fetus' heart rate to ensure it is receiving enough oxygen, monitor the mother's contractions, and

Treatment primarily consists of intrauterine resuscitation, the goal of which is to restore oxygenation of the fetus. This can involve improving the position, hydration, and oxygenation of the mother, as well as

Specifically, heart rate decelerations detected on CTG can represent danger to the fetus and to delivery. 668: 383:. The order of these interventions is set, and each step is done for 30 seconds with heart rate monitoring and assessment of chest movement prior to escalating to the next step in the algorithm. 375:
An algorithm is used to treat/resuscitate babies in need of respiratory support post-birth. The algorithm steps include: clearing the airways and warming, stimulating, and drying the baby,
