Using Tocolytics such as magnesium sulphate is one of the regular treatments to prevent preterm labor due to PPROM. However، there is a little clinical evidence about its beneficial effects on improving pregnancy outcomes، but however، in many centers it is used as first-line therapy. This study was performed with aim to investigate the effects of magnesium sulfate in delaying labor in women with PROM and prevention of its subsequent fetal complications. This two-blind clinical trial was conducted in the Mahdieh Medical Centre، Tehran between March 2010 and August 2012. Patients were allocated into two groups; intervention (magnesium sulphate، n=46) and control (placebo، n=46). Logistic regression analysis with Backward Stepwise method was used to evaluate the effect of independent variables on maternal and neonatal outcomes. The SPSS software version 20 was used for data analysis. Administration of magnesium sulfate has not been seen to associate with adverse effects in pregnancy outcomes. Also، the positive effect of this drug has been seen in relation to the increased duration of delay in delivery (P<0. 001) in women with premature rupture of membrane and reducing respiratory distress syndrome in their neonates (P<0. 002). Considering the affecting variables on active phase of labor، the logistic regression test showed that delay in the onset of the active phase of labor because of magnesium sulfate in the intervention group was 7. 2 times that of the control group (OR=7. 2، 95% CI: 2. 45-10. 1). Also، administration of this drug has no effect on the incidence of fetal mortality، sepsis، intraventricular hemorrhage، and need for NICU in the studied subjects. magnesium sulphate increased the delay duration in reaching active phase in mothers with premature rupture of membrane and no evidence of adverse foetal outcomes was not observed.

Postpartum hemorrhage is a major cause of maternal mortality especially in developing country. To estimate the rate of postpartum hemorrhage، visual estimation is the most common method used by staff، however، numerous studies have shown that it is incorrect، but it is an easy method and requires no tools. This study was performed with the aim to compare the visual estimation (without using criteria) and visual estimation using national guideline of vaginal delivery. This cross-sectional and descriptive study was performed on 112 women who had referred to Mashhad Omolbanin hospital for vaginal delivery in 2012-2013. After completion of the third stage of labor، the rate of bleeding was estimated by a midwife in the visual method and an interval of 1 and 2 hours after delivery. Also، at the same intervals، the rate of bleeding was estimated using a national guideline for vaginal delivery by one of the midwives working in the shift، then، a comparison between these two estimation methods was performed. Statistical analysis was performed using SPSS software and dependent t test. P The estimation of postpartum hemorrhage with visual estimation and national guideline estimation was significantly different (Visual estimation 37. 57 ± 12. 39 cc vs. National Guideline 45. 31 ± 13. 48cc) that this difference in estimation of bleeding was more observed in the first hour (P=0. 000). Simulation of the conditions of postpartum hemorrhage and training using national guideline of vaginal delivery can increase the accuracy of the estimation، therefore، training of personnel using this guideline is recommended.

Back pain is one of the most common musculoskeletal disorders that majority of women experience first episode of back pain during pregnancy. Back pain during pregnancy can reduce quality of life and cause disability in pregnant women. Exercise is one of options for back pain prevention and treatment during pregnancy that seems it does not have side effects and limitations of other treatment options. The aim of this review article was the evaluation of the effects of exercise on back pain during pregnancy.

the databases as ISI، Pubmed، Proquest، Ovid، Scopus، Cochran، Science direct، and sets of Springer، Sage، and search motor of Google with different combination of keywords related to the topic of the study were searched. Iran medex، magiran SID، and Irandoc were also used to find the related articles performed in Iran. Some keywords was used for searching including «pregnancy back pain»، «back pain»، «pregnancy»، and «exercise». This search was carried out in the period of 2001-2014. In addition، a manual search of the literature and the resources used in the literature was performed.

The results of literature searching showed that the performed studies about this field are very scattered and due to different designs of these studies، we cannot provide a definitively sum about the effect of certain exercise program on improvement of back pain during pregnancy. However، generally، the majority of studies show positive effect of exercise on reducing back pain during pregnancy.

Exercise has positive effect on treatment of back pain during pregnancy. Therefore، we suggest that healthy pregnant women who don’t have contraindication for physical exercise to use a standard exercise program during pregnancy for prevention and treatment of pregnancy related back pain.
