Premature Birth

Premature birth (before the deadline) is birth that occurs before the 37th week of amenorrhea (after last menstrual period).
Pregnancy lasts an average of 266 days from the date of fertilization. But, in obstetrical practice, early pregnancy is fixed on the first day of last normal menstrual flow, fertilization is considered to be held in approximately 14 days after the beginning of the last menstruation. So the average length of pregnancy is 280 days or 40 weeks of amenorrhea (absence of menstruation).
Premature baby is born between the 22nd and 37th week of amenorrhea (absence of menstruation). Instead, the child born after 41 weeks and 3 days is called postmatur. As prematurity is more important, so the baby is more fragile, and its possibilities to survive birth without medical care are low.
If a birth that occurs before the 32nd week (a critical gestational age), perinatal mortality is common, and neurological or psychomotor sequelae are possible.
For these reasons, it is very important that premature birth can be avoided by knowing the risk factors and their control as far as possible. Multiple Pregnancy, urinary or genital infections, placenta previa, diabetes, gestational hypertension (during pregnancy), age, lifestyle habits too strenuous, weight gain, or on the contrary, weak sharp ... all these factors must be considered during pregnancy .
Pre term newborn pathologies will present more or less important depending on the stage of pregnancy. For example, pulmonary immaturity may prevent the infant to breathe spontaneously and will require ventilatory assistance. If the body does not adapt to ambient temperature, the risk of hypothermia, and pre term newborn will be placed in an incubator. Will be given infusions of glucose solution because of the risk of hypoglycaemia. Immaturity of the digestive tract can cause metabolic and nutritional disorders.
