Daytime delivery and induced labor (Created page with "Labour can be induced, i.e. forced to start earlier than it would physiologically, with the help of certain medications and procedures.

Intrapartum management of preterm delivery (Created page with "Preterm infants are much more susceptible to hypoxia and obstetrical trauma, partly due to the foetal skull being less resistant to pressure, immature cerebral vasoregulation, and decreased production of lung surfactant.
