Maternal somatic support after brain death
According to Esmaelilzadeh, et al., "[a]t present, it seems that there is no clear lower limit to the gestational age which would restrict the physician's efforts to support the brain dead mother and her fetus." However, the older a fetus is when its mother becomes brain dead, the greater its chance for survival. Research into preterm births indicates that "a fetus born before 24 weeks of gestation has a limited chance of survival. At 24, 28 and 32 weeks, a fetus has approximately a 20–30%, 80% and 98% likelihood of survival with a 40%, 10% and less than 2% chance of suffering from a severe handicap, respectively."
