ABSTRACT
Background: Routine and continuous electronic monitoring of Fetal Heart Rate (FHR) in labour has become an established obstetric practice in high-risk pregnancies in developed countries. However, the same may not be possible in developing countries where antenatal care is inadequate with a large number of high-risk pregnancies and inadequate health care provider to patient ratios.
Aim: The objective of this study was to evaluate the admission cardiotocogram (CTG) in detecting fetal hypoxia at the time of admission in labour and to correlate the results of the admission CTG with the perinatal outcome in high-risk obstetric cases.
Materials and Methods: This was a prospective observational study was conducted in the labour from January 2018 to June 2018. The study included high-risk pregnant women, the emergency or outpatient department with a period of gestation ≥36 weeks, in first stage of labour with foetus in the cephalic presentation. All women were subjected to an admission CTG, which included a 20 minute recording of FHR and uterine contractions.
Results: Sixty patients were recruited in the study. The majority of women were primigravida in the 21-30 years age group. Pregnancy-Induced Hypertension (PIH) (5.6%), Oligohydramnious (8.3%) and Premature Rupture Of Membranes (PROM) (3.3%) were the major risk factors. The admission CTG were ‘reactive’ in 71.6%, ‘equivocal’ in 21.6% and ‘ominous’ in 6.6% women. Incidence of foetal distress, moderate-thick meconium stained liquor and Neonatal Intensive Care Unit (NICU) admission was significantly more frequent among patients with ominous test results compared with equivocal or reactive test results on admission. Incidence of vaginal delivery was more common when the test was reactive.
ery was more common when the test was reactive.
Conclusion: The admission CTG appears to be a simple non-invasive test that can serve as a screening tool in ‘triaging’ foetuses of high-risk obstetric patients in developing countries with a heavy workload and limited resources.
