The study is carried on 65 pregnant patients attending the outpatient clinics and
inpatient department of Obstetrics and Gynecology of Al Assad University Hospital from
February- 2013 until February- 2014. They were divided to three groups. The fir
st is
preterm labor with intact membranes (25 patients). The second is PROM (20 patients). The
third one is control group (20 patients). All of them were submitted to ultrasonography to
find cervical changes (cervical canal length and diameter of internal os in order to predict
preterm delivery. Cervical canal length has a sensitivity of 91.43%, a specificity of 100%,
a positive predictive value of 100%, a negative predictive value of 76.92%, and a relative
risk (95% CI) of 4.33 (1.61-11.69) among patients with short cervical canal length and
those with normal cervix.
Diameter of internal os as a predictor of preterm delivery has a sensitivity of 60%, a
specificity of 60%, a positive predictive value of 84%, a negative predictive value of 30%,
and a relative risk (95% CI) of 1.2 (0.86–1.68).
A Study was conducted on a random sample of (100) cases of pregnancies with preterm labour admitted to Al-Assad University Hospital Obstetrics and Gynecology section Lattakia during the period April 2012 until April 2013.
The efficiency of using ni
fedipine for inhibiting pre-term labour was studied together with the side effects during treatment and the cost of using nifedipine comparable to using another tocolysis.
The percentage of success in using nifedipine for inhibiting preterm labour by 60 m.g method during the first 24h was (78.5%) while it was (81.1%) by 90 m.g method for the same period.
The percentage of side effects was (19.7%) of which headaches were the most recurrent (50%).
Using oral nifedipine costs less than using intravenous Salbutamol used to inhibit preterm labour at Al-Assad University Hospital.
