aIntroduction: Metritis is one of the causes of maternal morbidity and there are many risk factors for it. Because of the importance of possible association of meconium-stained AMNIOTIC FLUID and maternal metritis the present study was done to determine whether meconium stained AMNIOTIC FLUID (MSAF) is associated with puerperal infection.Methods: In this case-control study 150 women with MSAF and 150 women with clear AMNIOTIC FLUID (gestational age > 37 weeks) were compared for puerperal metritis.Results: Subjects’ educational level, gestational age, gravida, mean vaginal exams, route of delivery and mean neonatal weight were not significantly different between the two groups. But mean maternal age and neonatal Apgar were significantly different in the two groups. That is, post partum metritis in women with clear AMNIOTIC FLUID occured less than women with MSAF (2.7% vs 10%, P<0.014).Conclusion: Since meconium stained AMNIOTIC FLUID is associated with metritis, special care in this regard is recommended.

AMNIOTIC FLUID volume (AFV) is one of the important parameters in the assessment of fetal well-being. The ability of ultrasound measurements to represent the actual AFV is unproven. This study was undertaken to compare correlation of conventional AMNIOTIC FLUID index (AFI) and radial AMNIOTIC FLUID index (RAFI) as a new method with actual FLUID volume on phantom. As an experimental study, 10 to 100 ml of water with 5 ml intervals was injected to a rubber bladder as a uterus phantom containing a 15 week gestational age fetus. The vertical diameter was measured in largest FLUID pouch at each quadrant. Four diameters were summed as conventional AFI. The largest radial diameter perpendicular to uterus and fetus was measured at four quadrants and were summed as RAFI. Databases were analyzed based on correlation and regression methods. RAFI and conventional AFI predicted 91.6% and 65% of variations of FLUID volume, respectively (P < 0.001). In conclusion, RAFI is more accurate and reliable than conventional AFI in the prediction of injected FLUID volume.      

Background and Aim: Puerperal infection describes any bacterial infection of the genital tract after delivery. It is the cause of 13% of pregnancy related deaths and the fifth leading cause of death. Some studies have addressed the role of meconium-stained AMNIOTIC FLUID in puerperal infection. The aim of this study was to evaluate the association between meconium-stained AMNIOTIC FLUID and puerperal infection. Materials and Methods: In this cohort study 300 pregnant women with gestational age≥37 weeks were divided in two groups. In case group AMNIOTIC FLUID was meconium-stained and in control group AMNIOTIC FLUID was clear. All patients were delivered by cesarean section and received prophylactic preoperative antibiotics. Patients were checked for puerperal infection within 40 days. All data was analyzed with SPSS. Results: Among 150 patients in case group 2 women (1.3%) developed a fever but none in the control group showed any signs of infection. There was no significant statistical difference between case and control groups (P>0.05). Conclusion: Although this study, revealed no relation between meconium-stained AMNIOTIC FLUID and puerperal infection, but, since both groups had received antibiotics, further comprehensive studies are needed to elucidate the role of meconium-staining of the AMNIOTIC FLUID in the occurrence of post-partum sepsis.
