Abstract:
In cesarean section under general anesthesia, inhalation anesthetics may compound fetal acidosis brought by maternal hypoxia or uteroplacental insufficiency. The chance af fetal distress may be increased with prolonged induction-delivery (ID) and uterine incision-delivery (UD) intervals in such cases. These studies were undertaken to evaluate the changes of fetal acid-base and blood-gas status according to these intervals in 58 parturients given cesarean section under general anesthesia. 58 neonates were divided into three groups according to their ID interval [group 1 (N=26): less than 6 minutes, group 2 (N=25): 6 to 10 minutes, group 3 (N=7): 10 to 15 minutes] and four groups according to their UD interval[group A (N=25): less than 60 seconds, group B (N=22): 60 to 90 seconds, group C (N=9): 90 to 120 seconds, group D (N=2): 120 to 180 seconds]. The pH, PCO2, PO2 and HCO3 values of the umbilical vein blood at delivery in the groups 1, 2, 3 divided according to ID intervals were 7.37+/-0.03, 7.36+/-0.04, 7.36+/-0.03; 39.75+/-4.83, 41.76+/- 4.03, 38.81+/-2.31; 34.35+/-745, 32.65+/-9.63, 30.89+/-11.28 (in mmHg); and 23.21+/-0.33, 23.30+/-0.26, 22.15+/-0.52 (in mEq/L), respectively, and in groups A, B, C, D divided according to UD intervals, they were 7.37+/-0.02, 7.37+/-0.02, 7.37+/-0.03, 7.36+/-0.06; 40.30+/-5.20, 40,63+/-3.11, 39.96+/-4.42, 40.03 +/-5.09; 32.35+/-8.23, 31.82+/-0.17, 35.67+/-8.35, 33.53+/-10.53 (in mmHg); and 23.14+0.26, 23.60+/-0.36, 22.88+/-0.67, 23.35+/-0.35 (in mEq/L), respectively. No significant differences in these values were present between these ID- or UD- based groups.
