Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Apgar score | 32 weeks to 40 weeks gestation | Apgar score is assessed at 1 min and 5 minute after birth. |
| Gestational week of delivery | 32 weeks to 40 weeks gestation | The gestational age of delivery is determined according to the last menstruation and ultrasonic diagnosis. |
| mode of delivery | 32 weeks to 40 weeks gestation | The mode of delivery including vaginal delivery and cesarean section, is determined by the exact condition of pregnancy. |
| newborn birth weight | 32 weeks to 40 weeks gestation | Newborn weight is measured immediately after birth. |
| birth height | 32 weeks to 40 weeks gestation | Birth height is measured immediately after birth. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| placental weight | 32 weeks to 40 weeks gestation | Placental weight is measured after delivery of the placenta. |
| umbilical cord placental insertion point | 32 weeks to 40 weeks gestation | The placenta is observed after delivery to determine the insertion point of the umbilical cord in placenta. |
| umbilical cord length | 32 weeks to 40 weeks gestation | Umbilical cord length is measured after delivery of the neonate. |
| coagulation function | 32 weeks to 40 weeks gestation | Coagulation function including prothrombin time and activated partial thromboplastin time is measured just before delivery. |
