Popis: To determine the factors that influence caesarean operative time and operative time effects on pregnancy outcomes.Prospective observational study of women undergoing a caesarean delivery (CD). Multiple antepartum, intrapartum and neonatal outcomes were assessed for their influence on the time of the CD and the time effect of CD on pregnancy outcomes.There were 386 (23%) caesarean deliveries performedor = 30 min, 1070 (65%) between 31 and 60 min, and 200 deliveriesor = 60 min. Women younger than 18 years (P= 0.004) and who had caesarean for fetal labor intolerance were associated with shorter operation time (P0.001). Factors associated with an increased operation time were age35 years (P = 0.049), body mass index (BMI)or = 30 (P0.001), pre-existing hypertension (P = 0.001), prior low segment transverse scar (P0.001), uterus incision other than transverse (P0.001), first-year resident as primary surgeon (P0.001) and accompanying sterilisation procedure (P0.001). Operation time was significantly related to blood loss (P0.001), likelihood of umbilical artery cord gas pH7.1 (P0.001) and Apgar scores at five minutes7 (P= 0.009).Operative time is shortened by age18 and delivery for fetal labor intolerance, lengthened by age35, BMI30, prior caesarean, uterine incision, operating surgeon inexperience and accompanying sterilisation. Increased operative time was linked with an increased blood loss, low five-minute Apgar scores and umbilical arterial pH7.1.
