General Purpose: To determine the effect of antenatal steroid before Elective C/S on prevention of respiratory morbidity of term neonates.
Study design: Randomized, clinical trial without placebo in two centers. The population of the study are babies born to pregnant women admitted to hospital for elective cesarean section in Yahyanejad and Babol Clinic Hospital due to repetitive C/S , in summer till winter 2015. Inclusion criteria for the mothers; Gestational age ≥39 weeks (based on ultrasound examination) and maternal cesarean section indications only because of repetitive C/S.
Exclusion criteria for the mothers; mothers with premature delivery, infection, diabetes, premature rupture of membranes and the use of steroids before birth and also C/s because of other reasons( other than the repeated C/S, such as medical or obstetric underlying disease, for example cephalopelvic disproportion, retinal detachment, and macrosomia. Inclusion criteria for neonates; All infants with gestational age of ≥39 weeks (which is based on ultrasound examination and also by the researcher’s physical examination after birth by the New Ballard Scoring system.).
Exclusion criteria for neonates; Undelying diseases such as IUGR, macrosomia , perinatal infection, congenital anomalies (Congenital heart diseases, etc.).Mothers are randomly divided into two groups. In this study, for each group of 50 samples were taken. The first groups of mothers’ were given Betamethasone (12 mg, daily ,IM, for tow days) within the at least 48 hours before the C/S, but the second groups of mothers’ were given nothing ,took only the usual routine care before the C/S. The neonates in both groups after birth were observed for any respiratory problems, including tachypnea, retraction, grunting and cyanosis and also for the requiring any resuscitations immediately after birth. Data like need to be admitted to the neonatal unit, or NICU and doing diagnostic and therapeutic studies were gathered. The incidence of respiratory problems after birth, the diagnosis of the underlying cause of distress, need for hospitalization, length of hospital stay and the need for oxygen administration in the two groups are compared. Data were collected by a questionnaire.
