ABSTRACT: Introduction: NST is a non invasive method used to evaluate foetal well-being. This test is a part of cardiotocography(CTG) used within at least 20 minutes after admission of patient, if it is the only screening test, for evaluation of foetal well being during delivery. Important component of NST are baseline foetal heart rate (FHR), baseline variability. Objectives: To measure and compare maternal and fetal biophysiological parameters among antenatal mothers in different positions before and during non-stress test [NST] at 0 min, 8th min, and 16th min. To find the association between antenatal mothers demographic variables and feto-maternal biophysiological parameters. Methodology: Descriptive research was adapted to carry out the study. 30 antenatal mothers who were selected using convenient sampling technique who admitted for delivery, as well as the mothers come for regular check up at OPD, SPMCW hospital, Tirupati. The observational schedule was prepared for assessing maternal and fetal physiological parameters under the three positions supine, left lateral and semi-fowler’s, were provided to assess the parameters before and during non stress test for 0 min, 8th min, 16th min. Results: the study findings revealed that There was no much difference in physiological changes (pulse, respiration, systolic and diastolic blood pressure) in maternal while changing the mothers in different positions ( supine, left lateral and semi-fowler’s) but normal in left lateral position. The significant findings for pulse at 0 min f = 4.189 with p <0.05, at 8th min f =14.122 with p < 0.01 and at 16th min f = 8.567 with p < 0.01. The association between demographic variables vs systolic blood pressure in position wise f=16.864 at p<0.01 and for diastolic blood pressure in position wise f=13.032 at p<0.05. There was no association between demographic variables vs pulse, respiration. In all the three positions (supine, left lateral and semi-fowler’s) the mother had normal fetal heart rate ranging from 120-160. And fetal movements were more in supine and left lateral position. The significant findings for fetal heart rate f = 6.229 at p < 0.01, f =3.613 at p < 0.05, f = 3.815 at p < 0.05. For acceleration at 8th min f = 8.713 at p < 0.01, at 16th min f =13.109 at p < 0.01. The association between demographic variables vs fetal heart rate in position wise f=19.114 at p<0.01 and fetal movements with educational status of the mother f=13.520 at p<0.05, in position wise f=14.119 at p<0.01. And acceleration in position wise f=28.654 at p<0.01. Conclusion: The findings of the study shows that left lateral position seems to be most comfortable position to the mothers during non stress test. Similarly semi-fowler’s position seemed to be mild discomfort and acceleration shown. Supine position during NST reported physical complaints as dyspnea and drowsiness. Recommendation: A descriptive study can be conducted on knowledge of non stress test among pregnant mothers.
