Abstract
Preterm laboris defined as the occurrence of regular uterine contractions after the age of viability and
before 37 completed weeks of gestations with intact membranes [1] . It is the leading cause of neonatal
mortality and a substantial portion of all birth-related morbidity. Preterm delivery accounts for 65% of
neonatal deaths and 50% of neurological disability in childhood. Prematurity rates have not changed in
recent decades [2]
