Check for errors and try again. There are cases in which emergency interventions are needed, both in high-risk and low-risk pregnancies. Issues with the uterus or placenta have the same impact as problems with the umbilical cord compromising the flow of oxygen and nutrients will harm the baby. This should involve regularly-scheduled ultrasounds and other tests such as Doppler flow, weight checks, amniocentesis, non-stress tests, and biophysical profiles. There are often secondary effects of hypoxia on cardiac myocytes, causing reduced cardiac output and causing further secondary neurological injury.

Hypoxic-ischemic encephalopathyin adults and older children (i.e. Both of these carry risks of hyperstimulation, where the uterus contracts too hard or too fast, potentially restricting the flow of oxygen to the baby. If they are born not breathing at all, they are resuscitated, first with positive pressure ventilation (PPV), and then, if the procedure is not successful, with several alternatives in an attempt to get the baby breathing again. In babies, HIE most often results from a medical complication and/or medical malpractice around the time of birth. Hypoglycemia can occur due to: (when the baby is small for their gestational age), (due to oxygen deprivation or starvation), HIE From Placental or Uterine Complications, HIE from Oligohydramnios and Polyhydramnios, HIE from Infections in the Mother or Baby, HIE from Intrauterine Growth Restriction (IUGR), intellectual and developmental disabilities (I/DD). As the baby develops, the amount of amniotic fluid tends to increase until the later parts of pregnancy, helping with nutrition and lung development. (2018, July 26). There are also many treatments and therapies that can improve function and alleviate symptoms of HIE in older children and adults (long-term care is discussed in more detail here). This can pose a risk for HIE and other birth injuries because the amniotic fluid that protects the baby from infection is gone. In these situations, vaginal delivery carries a high risk of shoulder dystocia and traumatic birth. ADVERTISEMENT: Radiopaedia is free thanks to our supporters and advertisers. When the umbilical cord is abnormally short, it may restrict the babys movement and development, or cause the placenta to become detached from the uterine wall (placental abruption).

Usually, this is not a problem, but if a baby gestates for too long, it can be exposed to hypoxic (low-oxygen conditions) as the placenta continues to deteriorate, and the baby may develop. In reversible encephalopathy, such as from organ failure, metabolic conditions, or infections, symptoms usually go away when you fix the problem thats causing them, and you may be able to regain your previous mental abilities. During labor and delivery, these vessels may rupture, leading to fetal blood loss and oxygen deprivation. This type of lung injury can severely impact the babys ability to deliver oxygen to its tissues. This type of therapy helps children with cerebral palsy (as well as adults) help in becoming more dependent when it comes to daily needs.
