“…Atul K Sood did a study in 500 AN women on evaluation of non-stress test in low risk pregnancy. 19,20 They found that 5 mins. APGAR score < 7 and neonatal admissions were more commonly associated with non-reactive tracings than reactive tracings (p < 0.005).…”

BACKGROUND Non-stress test is a non-invasive test, most commonly used for the antepartum evaluation of foetal well-being. Admission cardiotocogram is usually a 20 mins. recording of foetal heart rate immediately after admission to labour ward. Abnormal tracing might indicate and identify potential foetal compromise at an early stage and allow early intervention. Admission test enable the obstetrician to concentrate more on those foetuses having abnormal tracings than those with reactive tracings. MATERIALS AND METHODS It is a prospective study of assessing the validity of admission test as a screening test to differentiate high and low observational antenatal women. The study was conducted at Institute of Social Obstetrics and Govt. Kasturba Gandhi Hospital, Triplicane, Chennai during the period of April 2007 to April 2008; 800 number of antenatal women who were admitted through casualty were taken for the study based on the inclusion and exclusion criteria. After eliciting the history and complete clinical examination of the patient, the admission test is performed on each patient for 20 minutes. The admission test tracings were typed into-(i) Reactive, (ii) Suspicious, (iii) Ominous. Depending on the type of tracings, the mode of management varies. Patient can be divided into low and high observational status depending upon the tracings. RESULTS In this study, the number of patients in the age group between 18 to 20 years were 80 (10%), 21 to 29 years were 600 patients (75%) and the patients in 30 to 35 years were 120 (15%). In this study, the patients in primi were 496 (62%) and second gravida were 304 patients (38%). Highest number of patients were primi. Among them 784 patients were booked ones and 16 were unbooked. The admission test tracing pattern was such as reassuring pattern in 481 patients, suspicious in 267 patients and ominous in 52 patients. CTG observational status was low in 481 (60.13%) patients and it was high in 319 patients (39.87%). Spontaneous labour occurs in 624 patients (78%) and induced labour in 176 patients (22%). Since "p" value is less than 0.05, there is a significant correlation between type of tracings and mode of delivery. Among the total of 800 patients in this study, 380 (47.5%) number of the patients had the spontaneous labour in the primi gravida and 116 (14.5%) patients had the induced labour. In second gravida, it was about 244 patients (30.5%) in spontaneous labour and 304 (38%) were in induced labour; P value-0.226; statistically no significant relationship exists between Gravida and type of Labour. In this study, APGAR score more than 7 patients were 561 number (70.1%) and foetal outcome was good in 561 patients and it is poor in 239 patients. In this study the highest number of patients, 361 had the babies with birth weight of 2.4 to 2.7 Kgs. CONCLUSION The study shows that there is a good correlation between reactive tracings and good foetal outcome even with less frequent monitoring. Hence, the admission test can be used as a useful tool to differentiate between thes...

Summary. Calculation of the product of crown‐rump length and trunk area (CRLxTA), as measured by ultrasound between 34 and 36 weeks and combined with accurate assessment of gestational age in early pregnancy, was previously shown to be highly effective in detecting the small‐for‐dates fetus in a largely unselected series of patients. To assess the value of this two‐stage schedule in high‐risk pregnancies, 202 patients with singleton pregnancies at risk of fetal growth retardation were studied. Of the 53 babies that were small‐for‐dates at birth, 49 (92%) were identified in advance by CRLxTA measurement. In contrast to previous findings, measurement of trunk area (TA) alone was similarly effective, identifying in advance 48 (91%) of these small‐for‐dates babies.

Between 1981 and 1986, 9,840 women were monitored by antepartum nonstressed cardiotocography (CTG). A satisfactory fetal reserve pattern was detected in 91%, a reduced reserve pattern in 8% and a critical reserve pattern in 1%. The incidences of fetal growth retardation, Apgar score less than 6 at 1 minute, perinatal mortality and Caesarean section all increased significantly (p less than 0.001) as the degree of cardiotocographic fetal reserve worsened. Intrauterine growth retardation and/or low urinary oestriol excretion was associated with a highly significantly increased incidence of abnormal CTG traces (14.2%, p less than 0.001). A satisfactory fetal reserve pattern on cardiotocography was a reliable predictor of fetal well-being, since after exclusion of lethal malformations, the perinatal mortality rate in those patients monitored within 7 days of delivery was 3/1,000.
