title: [Caesarean section by vertical incision of lower uterine segment].
abstract: OBJECTIVE
  The aim of the study is to analyze the use of vertical incision of the lower uterine segment when performing Caesarean section (CS).
  
  
  METHODS
  The study includes 89 pregnant women who delivered by CS. The main group includes 40 cases with vertical incision in lower uterine segment (preliminary intention, but final decision made during surgery) and controls--49 cases with transversal incision of lower uterus segment with difficulties/complications of fetus extraction (30 with uterine lacerations and 19 with T-form incision). The mean gestational age in the main group is 32 g.w. (range 26-39) vs. 31 in control group (27-39). RESULTS. Vertical incision of the uterus is performed in 57.5% due to prematurity and lack of enough space for transversal incision (lower uterine segment not yet formed), in 25 % the cause is situs transverses of the foetus and the rest of the cases are related with technical difficulties in isthmicotransversal approach (myoma praevia, anomalies of the uterus, adhesions of the omentum). C.S. is performed for mean 66 min. in the main group vs. 74 min. with controls (p < 0.05). Time to extraction of the foetus is less than a minute in main group vs more than a minute with controls. No lacerations are found with vertical incision of uterus. Blood loss in main group is 664 ml, vs. 884 ml in control group (p < 0.05). Mean values of pH from umbilical artery of the newborn is 7.257 in main group vs. 7.19 in controls (p < 0.05), resp. Apgar scores atb 5-th min. is 7 vs 6. CONCLUSIONS. Vertical incision of lower uterine segment before the formation of the latter, with situs transversus of the foetus and difficult approach renders the option for less lacerations intra operationem, less birth trauma with better final outcome for the newborn.
