Obstetrical complications during delivery

Further study has suggested that environmental factors must play a very important role. These factors and their impact are poorly understood at the present time, but they include the possibility of maternal intrauterine viral infections during the gestational period, obstetrical complications during delivery, and perinatal conditions during the early days or months of the patient s life. Essentially, it would appear that schizophrenic patients have a genetic vulnerability to develop the disorder, which is manifested later in life if and when certain environmental conditions occur. 

Mothers of preterm infants were also more likely than mothers of full-term infants to have obstetrical complications at the time of delivery. Eighty percent of mothers of preterm infants had three or more obstetrical complications. Possible complications included premature labor, oremature rupture of membranes, prolonged rupture of membranes, Caesarean section, chorioamnionitis, and marginal placenta abruption. In contrast, only one mother of a full-term infant developed obstetrical complications during the perinatal period. 

Obstetrics. Most pregnancies progress uneventfully through delivery however, complications can arise suddenly. The majority of women deliver vagi-nally some of these deliveries are assisted by the use of forceps or a vacuum extractor (a suction device applied to the fetal head). Some deliveries are conducted via a cesarean section (operative delivery) because of problems that arise during labor or the intrapartum period. Common reasons for cesarean sections include lack of progress during labor or the development of fetal distress.
