title: [The assessment of the safety of vacuum extraction deliveries under routine epidural block].
abstract: To assess the safety of vacuum extraction (V.E.) deliveries under continuous lumbar epidural block (E.B.) with Bupivacain, the modified Krebs score in CTG, Apgar score, cord arterial blood acid-base balance, hypoxanthine, CPK, CPK-BB, Neuron specific enolase and c-AMP were examined. A total of 74 full term oxytocin-induced labors were divided into three groups: A) 21 cases by V.E. under E.B., B) 34 cases under E.B. only, and C) 19 cases without V.E. or E.B. There was no difference in age, gestational weeks in the three groups. However, the incidence of primiparas was highest in group A. Though CTG showed a temporary low Krebs score in group A within 30 minutes after the initiation of E.B., it was found that there was no significant difference between the three groups 30 minutes before parturition. The apgar score, cord arterial blood pH, PO2 and B.E. were also found to be similar in all three groups. Among various kinds of substances in the cord blood, both CPK-BB and c-AMP showed a striking rise in group A, compared to groups B and C. Therefore, the use of V.E. under E.B. might be hazardous to the well-being of the newborn infant.
