“…History of prematurity may indicate increase risk, since factors such as abnormalities of uterus, or cervical incompetence can cause repeated preterm labor. 27 Unlike in our study, other researchers found that oligohydramnios increased the risk for impending preterm delivery and intra-amniotic in ammation. Patients with oligohydramnios had a higher frequency of amniotic uid infection and/or in ammation than those without oligohydramnios.…”

Background: Preterm birth is a significant cause of perinatal morbidity and mortality and that becomes a major challenge in perinatal health care. Various pharmacological agents that inhibit uterine contractions are used in clinical practice to prevent preterm delivery. The maternal and fetal side-effect profiles of tocolytic agents are becoming an important consideration in selecting the drug of choice. Nifedipine, a dihydropyridine calcium entry blocker, is an effective tocolytic agent with low toxicity and teratogenicity, while carrying potential maternal as well as fetal vascular side effects due to its action on vascular smooth muscle. This study was performed to asses nifedipine use as tocolytic agent in preventing preterm birth, and assesing maternal as well as fetal vascular side effects.Methods: This experimental study with one-group pretest-posttest design was performed in 30 pregnant women undergoing nifedipine as tocolytic. Doppler assessment of uterine, umbilical and fetal middle cerebral arteries, ductus venosus, and cerebroplacental ratio was performed before and 48 hours after nifedipine therapy. Wilcoxon's signed ranks test was used to analyze the difference between the two variables. A P-value of < 0.05 was considered significant.Results: The result of the study showed nifedipine was associated with a significant decreased of pulsatility index uterine artery (p = 0.016; p-value<0.05) and umbilical artery (p = 0.037; p-value<0.05) after 48 hours therapy, while pulsatility index of fetal middle cerebral arteries, ductus venosus, and cerebroplacental ratio did not change significantly.Conclusion: The study concluded that nifedipine as tocolytic increased blood flow of uterine artery and umbilical artery after 48 hours therapy.

Background Preterm birth is one of the most common causes of mortality in infants. Despite advances in health care and better access to health services in many countries, preterm birth has increased over the past two decades. Methods This case control study was conducted on two groups with 100 participants including 100 preterm infants (case) and 100 term infants (control) with gender match in Kurdistan Province-Iran in 2018. The required information was collected from medical files and interviewing the mothers as to demographical information, midwifery specifications, background diseases, disease over pregnancy term, and infants’ information. Conditional logistic regression test was used to estimate the final model and compute the risk ratio. Results Multivariate regression analysis showed that the risk of preterm birth in individual with AB blood type was higher (OR=5.04; 95% CI 1.40-18.08). In addition, the risk of preterm birth was higher in the mothers with a history of stillbirth (OR=13.63; 95% CI 1.39-133.5). Preterm birth was significantly related to the history of birth diseases, history of pregnancy diseases, and using medicine for specific diseases during pregnancy. Conclusions Blood type of mother, history of still birth, history of birth disease, history of pregnancy diseases, using medicines for specific diseases, and history of preterm birth were the risk factors of preterm birth. These factors need to be taken into account before and during pregnancy. Paying more attention to these factors attenuates the rate of preterm birth and premature infants and in turn the mortality rate of infants and mothers.
