Comparative study of clinical methods versus ultrasound methods for accurate gestational age determination in different trimesters of pregnancy, Ndop District Hospital, North west region, Cameroon
Abstract
Introduction: gestational age is the estimated age of gestation from a fetus during its development and this is very important for the mother who wants to know when to expect the birth of her baby and for the health care provider so they can chose the time at which to perform various assessment. However, from the information outlined in this research, it can be seen that last menstrual period (LMP) and follicle-stimulating hormone (FSH) are used to assess gestational age. While GSD, CRL, BPD, HC, AC and FL are biometric parameters that can be measured on a fetus in order to estimate gestational age. Many clinicians and ultrasonologists feel that if they are unable to obtain an accurate measurement at the time, they have sometimes failed to do an adequate job.
Methods: the study was a comparative study on clinical method versus ultrasound method for accurate gestational age determination and also to determine the significance of fetal biometric parameter in GA determination. The study was an observational, cross sectional and participatory study for a period of 5 weeks from the 22nd of January to the 22nd of February 2018. A total of 72(74.2%) ANC cases were sampled during ultrasonography. Gestational ages from their clinic card were recorded. Twenty five questionnaires were given out to 25(26.8%) health care personnel to assess clinical method. Data was analyzed using SPSS version 16 plus and Microsoft Excel 2010.
Results: results showed the best clinical method used was LMP with 9(36%) but when compared to ultrasound, ultrasound presented with greater accuracy of 15(60%) and clinical method 10(40%).
Conclusion: based on the findings, it could be concluded that compared to the physical examination and clinical methods, ultrasound examination of the fetus provided the physician and health care professionals with greater accuracy for gestational age.
