Premature delivery  (PREMATURE delivery)


Confinements (603-4) and deliveries (603-4*) are said to occur at term1 when the pregnancy has lasted for the normal period of about nine months. If pregnancy ends before the normal period (but after six months) there is a premature delivery2 or premature confinement2 or premature birth2 and the product of conception is called a premature baby4. Births which are not premature are called births at term3 or full-term births3. The word prematurity5 is sometimes used to refer to phenomena connected with premature delivery. A classification of births by stage of development that does not depend upon an estimate of the period of gestation is used in many countries. In this classification a live-born infant with a birth weight6 of 5,5 lb. (2,500 grammes) or less is said to be immature7.
