    Accuracy of Ultrasound in Fetal Sex and Weight Determination in the 2nd & 3rd Trimester When Performed By Radiology Residents & Recent Graduates: A Cross Sectional Facility Based Study
    (Addis Ababa University, 2015-10) Hashim, Yasmin; Kebede, Tesfaye(Associate professor)
    Background: Ultrasound is one of the non invasive methods for fetal sex determination and with its introduction visualization of the fetal genitalia has become possible. Although mainly fetal sex determination is done for parental curiosity it has also some clinical implication. Accurate prenatal EFW in late pregnancy and labor is extremely useful in management of labor, aiding in decision making about instrumental delivery, trial of labor after caesarean delivery and elective Cesarean section for patients suspected of having a macrosomic fetus. Objective: Purpose of this study was to assess the accuracy of ultrasound in fetal sex determination in 2nd & 3rd trimester & weight determination in those ≥ 38wks when it is performed by those with lesser experience and exposure Methods: Obstetric ultrasound and ultrasound of the perineal region of the fetus was done on 600 pregnant women to detect the sex of the fetus with gestational age from 16 weeks to term. Completer data and information was available in 55o of the study. There were 20 twins in the study making the overall fetuses in the study 570. For fetal weight accuracy study 235 mothers with gestational age of ≥38weeks were included. Ultrasound results were registered on pre-prepared form at the time of examination. The sex & weight was confirmed at the expected time of delivery through a phone call to the mothers and for some by revising their medical cards. Results: Out of 570 fetuses ultrasound was able to determine the sex for 527 (92.5%); 287 of whom were confirmed female and 240were male. Overall accuracy was 84.92%. Accuracy for females was 91.63% and for males was 92.08%. When the not sure cases are excluded and samples for which actual sex determination was done are analyzed the accuracy was found to be 92%. From the 235 samples with GA of ≥38 weeks the accuracy of ultrasound fetal weight estimation within 10% of actual birth weights was 85.5%. The mean absolute error of estimated fetal weight was 226.67gm. Ultrasound generally underestimated the birth weight. Specifically ultrasound overestimated the fetal weight in those <2500gm and underestimated in those>4000gm. Conclusion: Ultrasound is an accurate method to determine the fetal sex in the second and third trimesters with a sensitivity of 90% and specificity of 93.2% even when it is performed by those with less experience and exposure. In conclusion EFW by ultrasound in term pregnancies using the Hadlock formula was found to have a high accuracy rate when it is performed by those with less experience and exposure. So it can be applicable to make clinical decisions even when it is done by those with less experience. The over estimation of LBW and under estimation of macrosomia found in ultrasound weight estimation should be given due attention

    An Audit of Completion of Ultrasound Request form at BLH
    (Addis Ababa University, 2014-11) Berhane, Hailemariam; Kebede, Tesfaye(Associate professor); Teferi, Seife(Assistant Professor)
    Objective: To audit the adequacy of completion of ultrasound request formsreferred to the radiology department from the different wards /OPD of the hospital Design:Cross-sectional study Place and duration of study:Diagnostic Radiology Department of Addis Ababa University of medical faculty, from October 15, 2014 to October 30, 2012. Methods:A total of 218 ultrasound request form in study period were analyzed for completion using a blind ended questioner. The data were cleaned and entered in to SPSS-20 software package. Frequency and percentage were used for this categorical variable. Result:A total of 218 ultrasound requests forms were reviewed. All of them had the names of the patients filled, 218 (100%) and almost all had their father name filled except 5(2.3%). Only 168 (77.7%) of them had their ages filled, and 164 of 218 (75.2%) had their sex filled (Table-1).One hundred and eighty nine (86.7%) had hospital number while, 29(13.3%) did not haveinformation regarding hospital number.Detailed clinical data were filled in 184 (84.4%), and not mentioned at all in 34(15.6%) of them. Although 83.3% (181/218) of them had mentioned the requesting physician name, only 8 (3.7%) and 6 (2.8%) filled the relevant laboratory information and previous data respectively Conclusion: We conclude that radiological investigation forms are still incompletely and inadequately filled. This will have effect on the quality and the overall service provided by the radiologist and may have effect sometimes on clinical decisions and outcomes. There is need to encourage the managing clinician to complete and adequately fill all the required information into the request form and appreciate its importance to patient’s management. This can be achieved by increasing the awareness of referring clinicians through repeated continue medical education in conjunction with the radiologists and the need for a regular clinical-radiological meetings.
