However, subsequent scientific innovation has advanced the threshold of viability to 22 to 24 weeks’ gestation (Watkins, 2020). Moreover, the overall survival rate for preterm neonates <29 weeks’ gestation approaches 80 percent (Travers 2018). Still, the preterm newborn is susceptible to many serious medical complications both early and later in life (Table 34-1).
