AbstractObjectiveTo determine a reference interval for maternal arterial blood values during vaginal delivery and to elucidate the effect of common maternal characteristics and obstetric interventions on maternal acid base values during vaginal and planned cesarean section (CS).DesignProspective, observational study of randomly selected women undergoing vaginal deliveries and planned CS at Skåne University Hospital, Malmö, Sweden.ResultsTwo hundred and fifty women undergoing vaginal delivery (VD) and fifty-eight women undergoing planned CS were recruited. We found significant differences for gestational age, parity, artery pH, pCO2, pO2, sO2 and cord venous pH, pCO2 and lactate between the two study groups (P < 0.005). For women undergoing vaginal delivery, we found significant changes in base deficit, hemoglobin, bilirubin, potassium, glucose and lactate values as compared to women with planned CS (P < 0.02). Maternal characteristics did not significantly affect acid base parameters however, multiple regression showed significant associations for the use of epidural anesthesia on maternal pH (P < 0.05) and pO2 (P < 0.01); and synthetic oxytocin on pCO2 (P = 0.08), glucose (P < 0.00) and lactate (P < 0.02) in maternal blood. Maternal arterial pH, pCO2 and lactate correlated significantly to values in venous umbilical cord blood (P < 0.000).ConclusionsReference values for maternal arterial blood gases in vaginal deliveries for term pregnancies were outlined and we found that most arterial blood gas parameters varied significantly according to mode of delivery. The use of different obstetrical interventions like epidural anesthesia or synthetic oxytocin, resulted in significant changes in blood gas values.

Fetal Acidosis

Background: The purpose of intrapartum fetal monitoring by cardiotocograph (CTG) is to identify early signs of developing hypoxia so that appropriate action can be taken to improve the perinatal outcome. Although CTG findings are well known to monitor the progress of the labor due to the paucity of recommendations, there has always been a clinical dilemma as the term fetuses respond differently than a preterm fetus. However, umbilical cord blood pH can distinguish the infant at high risk for asphyxia and related sequel. Therefore, because of differences in fetal physiology in term and preterm fetuses, CTG findings vary, and hence the validity of CTG to determine fetal acidosis should be different. Aims and Objectives: This study aimed to correlate abnormal intrapartum CTG findings with umbilical cord blood pH in term and preterm labor and thus evaluate the success of CTG in predicting fetal acidosis during labor. Methods: The present study included 210 women in labor (70 preterm and 140 term) with abnormal intrapartum CTG that was classified as per 2015 revised International Federation of Gynecologists and Obstetrician (FIGO) guidelines. Immediately after delivery 2 ml Umbilical artery cord blood sample was taken in a pre-heparinized syringe for analysis, pH <=7.2 was taken as acidosis and pH >7.2 was taken as normal. The measured data were maternal general characteristics which included gravida status, associated comorbidities, method of induction and character of liquor, the intrapartum CTG tracings recorded the cord arterial blood pH and the neonatal characteristics such as APGAR score and neonatal outcome. Results: Data from 70 preterm labor was compared with 140 term labor. In this study, 20.9 % of the babies had acidosis. Suspicious CTG due to decreased variability were more common in the preterm group than in the term group (21.4% vs. 8.6% p<0.05). Positive predictive value (PPV) of abnormal CTG for fetal acidosis in the preterm group was found to be higher than that in term group, PPV of pathological CTG being even higher than suspicious CTG. Women with suspicious CTG had 82 % less risk of fetal acidosis as compared to pathological CTG. Women with Bradycardia had 5.9 times the risk of fetal acidosis as compared with normal and tachycardia. Conclusion: Abnormal CTG should be managed appropriately without any delay to prevent acidosis and cord blood pH should be done in all labors with abnormal CTG. However, our findings of a higher incidence of lower cord blood pH and suspicious CTG due to decreased variability alone, highlight the limitation of criteria currently used for interpretation of CTG in preterm labors.

Fetal Acidosis

Background: Even in low risk mothers, fetal acidosis occurs as in high risk groups. Aim of fetal monitoring is to detect early response to intrauterine hypoxia and prevent irreversible neurological damage and death. Objective of this study was to correlate the intrapartum fetal distress with the help of cardiotocography CTG with umbilical cord blood sampling.Methods: A total 100 consecutive patients attending the labor ward were studied. Immediately at birth, before the baby’s first breath and before delivery of the placenta, the umbilical cord blood was collected as per the standard guidelines laid down in the standard textbooks. Fetal acidosis was assessed by umbilical cord arterial blood pH. Fetal acidosis was considered when umbilical artery pH <7.2. Cardiotocography features were used to clinically diagnose fetal distress.Results: Most of the mothers were multigravida. They belonged to the age group of 20-25 years. Only 18% had abnormal CTG. Out of 50 mothers with normal vaginal delivery, all had normal CTG. Out of 43 mothers who were delivered by LSCS, no one had normal CTG, 25 had indeterminate CTG and 18 had abnormal CTG. As CTG became abnormal, proportion of mothers with the thick meconium increased. NICU admission proportion increased as CTG changed from normal to the abnormal. There was a significant association between the abnormal CTG and the umbilical cord blood pH being acidic.Conclusions: CTG is a simple test, easy to perform and can alert obstetrician for necessary interventions in case of an abnormal CTG. It can detect fetal distress in labor thus helping to reduce neonatal morbidity by early intervention in cases of abnormal tracing.
