The recent case of a brain-dead woman in Georgia who has been kept alive on life support for the last three months, not for her own survival, but to allow her unborn baby to reach viability, has stirred online debates.
Adriana Smith, 30, was nine weeks pregnant when she visited a hospital after suffering from intense headaches. However, no tests were performed and the next morning, she turned unresponsive as her condition deteriorated. A CT scan performed later revealed several blood clots in her brain, reported 11Alive.
Declared brain dead, Adriana would be receiving life support, till she gives birth, due to Georgia’s Heartbeat Bill that bans abortion once embryonic cardiac activity is detected, typically around six weeks gestation.
Her mother April Newkirk doesn't have a choice legally and is heartbroken to see her daughter 'breathing', but unresponsive. She fears for her unborn grandson's survival and is concerned about his health.
“She’s pregnant with my grandson. But he may be blind, may not be able to walk, may not survive once he’s born,” she told 11Alive.
Adriana's case has sparked questions about what science knows, what the law dictates, and what happens to babies born under such extraordinary circumstances. While rare, cases like these have occurred before, and the outcomes, both medical and emotional, are far from simple.
Brain death during pregnancy
There have been past cases where families and doctors faced a choice between discontinuing life support or continuing full medical intervention to keep a brain-dead woman alive in hopes of allowing the fetus to reach maturity.
According to a study published in International Journal of Critical Illness & Injury Science, 30 cases between 1982 and 2010 of brain dead pregnant women have been reported where the body functions were maintained to
allow the baby to develop in the womb.
However, only 12 viable infants were born and survived the neonatal period, as per the
study.
Based on earlier reports, doctors used to consider the fetus's age a key factor when deciding whether to keep a brain-dead woman on life support. But with advances in life-support technology and critical care, it's now possible to maintain the mother's vital functions regardless of how far along the pregnancy is, making gestational age less of a deciding factor.
A success story
This
case detailed in journal Cureus involves a 31-year-old woman who was 22 weeks pregnant when she was declared brain-dead due to intracranial and subarachnoid hemorrhage.
A multidisciplinary medical team carefully evaluated the situation and decided to continue somatic support — keeping her body functioning — to allow the baby to grow until it was developed enough to survive outside the womb. After 11 weeks of life support, at 33 weeks of pregnancy, a cesarean section was performed. The result: the successful birth of a live infant.
A case reported in the American Journal of Case Reports describes a brain-dead woman at 16 weeks gestation who was maintained on life support for 117 days, resulting in the birth of a healthy child with good one-year outcomes.
Similarly, a systematic review in the American Journal of Obstetrics and Gynecology analyzed multiple cases and found that with appropriate medical management, the majority of infants born under such circumstances had favorable outcomes.
What happens to the baby
The gestational age at which the mother becomes brain-dead is a critical factor. The survival rates of infants increase with gestational age: approximately 20–30% at 24 weeks, 80% at 28 weeks, and 98% at 32 weeks.
However, maintaining somatic support in brain-dead pregnant women presents significant challenges. Complications such as infections, hormonal imbalances, and cardiovascular instability can arise, potentially affecting fetal development.
There could be problem maintaining adequate blood pressure and oxygen levels which can lead to fetal hypoxia (low oxygen levels) and ischemia (reduced blood flow). This may cause long-term neurological damage.
The child may not receive adequate nutrition as a brain dead mother may not be able to digest and absorb nutrients.
The mother's body may not be able to sustain a pregnancy for the full term due to the complications associated with brain death. This can result in premature delivery, raising risk of complications.
