dc.description.abstractTo determine values of mid pregnancy cervical length and internal ostial diameter in a low risk population and correlate measurements with parity and gravidity. A cross sectional study of booked pregnant women at gestational age of 20 – 24 weeks with viable singleton pregnancy. Women with multiple pregnancies, cervical incompetence, cervical cerclage, previous history of cervical surgery, previous myomectomy, caesarean section scars, vaginal bleeding/low lying placenta, medical disorders in pregnancy were excluded. The transvaginal ultrasound scanning was performed with Aloka ultrasound machine at the frequency of 7.5MHz. The lubricated probe was inserted gently to a depth of 2-3 inches into the vagina. Cervical length was measured as distance between the internal and external cervical ostia along the endocervical canal. Internal Os was defined as the level where the cervical canal meets with the amniotic sac. Data were analyzed using Statistical Package for Social Sciences (SPSS) software package version 20. The results were expressed with descriptive statistics. P value of <0.05 was taken as significant. Percentiles, Pearson and Spearsman correlation tests were calculated and used. There were 159 participants. The mean age of the participants was 29.58±4.64 years and a range of 15- 39 years, primigravida were 37.7%, 57.2% w e r e m u l t i g r a v i d a s w h i l e ( 5 % ) w e r e grandmultiparous. The mean cervical length of the population was 39.72 ± 6.81mm and the range 25.00- 62.00mm.The mean Internal Os diameter was 3.06 ± 0.74 mm, range of 2.00- 5.00mm.In the study population 18.9% had internal Os diameter of < 3mm while 81.1% had internal Os diameter of 3-5 mm. The mean cervical length at 5th, 10th, 25th, 50th, 75th, 90th and 95th percentiles were 31mm, 32mm, 35mm, 39mm, 44mm 49mm and 52.00 mm respectively. Correlations between parity, gravidity and cervical parameters were not statistically significant as well as the relationship between cervical length and internal os diameter. The mean values of cervical length and internal os diameter at 20-24 weeks in singleton pregnancy with low risk for preterm delivery were found to be 39.72 ± 6.81mm and 3.06 ± 0.74 mm respectively. There was no significant correlation between the cervical parameters, parity and gravidity.en_US
