RISK FACTORS OF BIRTH INJURY
Aim. To identify the risk factors of birth injury. Materials and Methods. I retrospectively assessed 262 case histories of labor including 131 cases of birth injury occurred in Omsk during 2008-2016. The control group was formed as a sample of 131 healthy childbirths. Results. Birth injury frequently occurred in patients with pregnancy complications, i.e. intrauterine infection (32.1%), placental abruption (14.5%), intrauterine hypoxia (9.2%), placental insufficiency (19.1%), pre-eclampsia (16.0%), preterm birth (45.0%), postterm pregnancy (6.1%), long anhydrous period (18.3%), premature rupture of membranes (42.0%), labor abnormalities (11.5%), and chronic iron deficiency anemia (15.3%). Conclusions. Risk factors contributing to birth injury are complications of pregnancy (intrauterine infection, placental abruption, intrauterine hypoxia, placental insufficiency, pre-eclampsia, preterm birth, postterm pregnancy), delivery (long anhydrous period, premature rupture of membranes, labor abnormalities), and concomitant disorders (chronic iron deficiency anemia).
