THE INCIDENCE OF PREMATURITY IN THE HOSPITAL OF SHIRAZ UNIVERSITY OF MEDICAL SCIENCES AND HEALTH SERVICES, 1999

Premature labor is one of the great difficulties endangering the health of the society and undoubtedly one of the tragedies of the world since many people suffer from the consequenccs of prematurity. An analytic research. was performed from the records of all premature infants (gestational agc less than 37 weeks) who were admitted to hospital of Shiraz Medical university (Zeinabieh and Hafez) in 1999. 160 neonates were chosen randomly as a control group. The clinical characteristics recorded included: Motherʹs age, route of delivery, parity, motherʹs difficulties and diseases, prenatal care, sex. apgar, birth weight, gestational age, neonatal diseases and outcome. Among 9743 neonantes who were born at the above mentioned hospitals in one year, 522 newborns were prematurc infants: an incidence of 53.5 pcr 1000 deliveries. There was a reverse relation between weight and gestational age with neonatal death (P<0.000001).The numbcr of alive infants in normal vaginal delivery (87%) was more than infants born cesarian sections (71.6%) (P<0.0005). Thcre was no significant relationship between gender and outcome, or the routc of delivery and gestational age. In comparison to neonates in the case group, the control group had the highest apgar scores in the first and fifth minutc, 22.5% versus 72.5% and %0.6 versus 10.9%respcctively (P<0.0002). Regarding prenatal care, the control group enjoyed morc care (78.1%) as compared to the case group (50.3%) The most prevalent discases of premature infants were: respiratory distress syndrome, .jaundice, and scpsis. In 78.7% of these neonates, their mothers had problems at delivery time such as: premature rupture of membrane, premature labor pain. and preecclampcia. It is certain that, increasing thc motherʹs knowledge and information, especially in young mothers, about the dangers of prematurity, the importance of prcnatal care and avoidance of premature labor is very imporant factors in decreasing the incidence of prcmaturity.
