[Effects of acid-base balance and Apgar score on fibrinopeptide A and fibrinopeptide B beta 15-42 in umbilical cord blood].

Previous studies on asphyxia neonatorum show that the infant's blood is in a state of hypercoagulability at such a time. In the present study, we determined the amount of fibrinopeptide A (FPA) and fibrinopeptide B beta 15-42 (FPB beta), new sensitive indicators of the coagulation-fibrinolytic system, in the newborn, and examined their relationship to the acid-base balance in umbilical artery blood in elective cesarean section and vaginal delivery, as well as to the Apgar score (Ap. S). In addition, the findings in umbilical cord blood were then compared with those in the blood of normal adults. The results were as follows: In vaginal delivery, infants with Ap. S at 5-7, pH, had significantly lower HCO-3 and BE readings lower while PCO2 was significantly increased, which indicated respiratory and metabolic acidosis. In the vaginal delivery group, FPA was significantly increased in infants with pH under 7.24, PCO2 over 50 mmHg, BE under -8 and Ap. S at 5-7, and as well as in infants in the elective cesarean section group with Ap. S at 5-7. This suggests that the production of thrombin is accelerated if the fetus is asphyxiated. FPB beta was not significantly different among groups. However, FPB beta was significantly higher in various vaginal delivery groups than in the elective cesarean section group (Ap. S greater than or equal to 8), which implies acceleration of the production of plasmin and fibrinolysis in vaginal delivery. FPA and FPB beta were markedly increased in umbilical cord blood as compared with the blood of normal adults. This suggests that blood coagulation and fibrinolysis were accelerated in umbilical cord blood.

Birth weight, Apgar scores, labor and delivery complications and prenatal characteristics of Southeast Asian adolescents and older mothers.

The study population included 337 adolescents and 876 mothers who delivered live-born, singleton infants in the Maternity and Infant Care Program at the Minneapolis Health Department between 1980-1982. Whites and blacks on the average experienced menarche 1-2 years earlier than the Southeast Asians although age of first pregnancy was 2 years later for the Southeast Asians. In spite of the significantly later ages of entry into prenatal care, lower weight gains, and hematocrits among the Southeast Asians, compared to the white and black populations, overall height-weight status on admission compared favorably with whites and blacks. The virtual absence of alcohol and tobacco consumption among the Southeast Asians may in fact contribute to the generally favorable Apgar scores, length of gestation, and birth weights. The high frequencies of alcohol and tobacco consumption among white adolescents during pregnancy suggest the need for more intervention to discourage smoking in this population. Further, the potential adoption of these substances needs to be discouraged among the Southeast Asian adolescents. While 2-4% of the whites, blacks and Hmong adolescents experienced eclampsia, 1% of the older Hmong mothers and none of the other Southeast Asians experienced eclampsia. The most frequent complication for all groups was perineal laceration.

Phenylephrine in treating maternal hypotension due to spinal anaesthesia for caesarean delivery: effects on neonatal catecholamine concentrations, acid base status and Apgar scores.

Maternal and neonatal catecholamine concentrations, following the use of either phenylephrine or ephedrine to treat a drop in maternal blood pressure after spinal anaesthesia for caesarean delivery, were compared. Patients were randomly assigned to one of two groups: Group 1 patients (n = 20) were treated with ephedrine given as 5 mg intravenous bolus injections; Group 2 patients (n = 20) were treated with phenylephrine given as 40 micrograms intravenous bolus injections, for decreases in maternal systolic blood pressure to maintain maternal systolic blood pressure above 100 mmHg. Maternal vein (MV), umbilical vein (UV), and umbilical artery (UA) blood samples were taken at the time of delivery. Samples were analyzed for catecholamine concentrations and blood gas values. Noradrenaline concentrations in UA, UV and MV (at delivery) samples were significantly higher in group 1 compared to group 2; they were 6858 +/- 3689 vs 1674 +/- 944 pg.ml-1 (P < 0.0001), 1265 +/- 758 vs 395 +/- 470 pg.ml-1 (P < 0.001) and 239 +/- 165 vs 103 +/- 93 pg.ml-1 (P < 0.01), respectively. Comparing blood gas values between groups 1 and 2, statistically significant differences were observed in UA pH (7.28 +/- 0.01 and 7.32 +/- 0.01 pH units, P = 0.01), UA pCO2 (7.32 +/- 0.24 and 6.68 +/- 0.21 kPa, P = 0.03), UA base excess (2.2 +/- 0.4 and 0.9 +/- 0.4 mmol.1-1, P = 0.04) and UV base excess (2.0 +/- 0.3 and 0.7 +/- 0.3 mmol.1-1, P = 0.004). No significant differences in maternal characteristics, acid base values, incidence of nausea and vomiting, and Apgar scores were observed between groups. Phenylephrine appears to be as safe and effective as ephedrine in treatment of drop in blood pressure in healthy non-labouring parturients undergoing caesarean delivery. The use of phenylephrine was also associated with significantly lower noradrenaline concentrations in both mother and neonate.
