Predictive value of fetal scalp pH and base excess for fetal acidosis and poor neonatal outcome

Caesarean section was the first obstetrical operation that saves the life of the baby when normal delivery fails. Spinal anaesthesia is the most appropriate method for caesarean section. But hypotension is the most common side effect of it in patient with pregnant uterus. To compare the vasopressor effects of ephedrine and phenylephrine in ameliorating hypotension in elective caesarean delivery receiving crystalloid coloading, during intrathecal bupivacaine injection.: Study participants were randomly divided into two groups of 50 patients each. After subarachnoid block, all the parturients were given rapid administration of ringer lactate solution 20ml/kg, during the initial 5 minutes of surgery the parameters such as oxygen saturation, blood pressure and pulse rate recorded for every one minute followed by every five minutes until the completion of the surgery. The incidence of hypotension, bradycardia, nausea/vomiting, block height and requirements of vasopressor (ephedrine and phenylephrine) were recorded. Apgar score, and blood sample from umbilical cord was taken and sent for blood gas analyses to determine the neonatal outcome.: Vasopressor consumption was more in phenylephrine group (92±112 µg) compared to ephedrine group (4.8±5.5 mg) which was statistically significant p=0.0001. The neonatal outcome was statistically significant regarding umbilical cord pH (Group E-7.2±0.06 and Group P-7.37±0.04 with p=0.002) but clinically no true fetal acidosis in either groups and no significant changes regarding Apgar score in the two groups.: Thus we conclude that that ephedrine 6 mg and phenylephrine 100 µg does not differ in their efficacy to manage hypotension during spinal anaesthesia for caesarean delivery. However, maternal bradycardia was more in the phenylephrine group with equal incidence of fetal acidosis in the study groups.

Background: Admission cardiotocography (CTG) is a test of fetal wellbeing performed during labor. A normal CTG is for 20-30 minutes and ranges from 110-160 bpm with beat to beat variability, two accelerations and no decelerations with two contractions (as per NICE 2018 guidelines). To study comparative efficacy of admission CTG in predicting neonatal out in high risk, low risk and universally in all pregnancy.Methods: All high risk as well as low risk patients coming to labor room in labor were included in the study. CTG print was taken, and neonatal outcome as NICU admission were noted after taking written consent.Results: 189 cases were taken.138 were high risk cases, CTG was taken: 91were reassuring, 47were abnormal (non-reassuring +abnormal). In terms of NICU admission, 21 and 26 neonates were admitted. Out of 51 low risk cases, 33 had reassuring CTG, and18 had abnormal; 7and 6 was the number of NICU admission, respectively. When compared, highest sensitivity, specificity and positive predictive value of 55.31%, 77% and 55.3% was seen in high risk pregnancy, whereas negative predictive value (78.8%) was slightly higher in low risk cases.Conclusions: Admission CTG is a good predictor of neonatal outcome. Its predictive efficacy is more in high risk cases. It’s practicality in revealing poor neonatal outcome is more.
