[Relationship between cervical dilatation and fetal descent in the first 2 hours of active labor with method of delivery in term nulliparous women]

Diagnosing parturients in risk of cesarean section early in the beginning of active phase of labor, is very important. This may let take necessary action to accelernate labor [delivery] and prevent maternal mortality and morbidity due to late cesarean section. During a period of 8 months from July 2004 to March 2005, 216 primiparous women, with term pregnancy and cephalic single fetus, referred to Imam Reza hospital in [during] active phase of labor, were studied. Changes of cervical dilatation and descent of the conceptus were observed. Parturients were devided to two groups, vaginal delivery and cesurean section. Protraction or arrest disorders were the indications of cesarean deliveries. Findings were analysed through using T-Test, unilateral variance and Chi square test. The more change in cervical dilatation in the first 2 hours of active phase of labor, the less possibility of cesarean delivery [p< 0.001]. Also the more rate of the conceptus descent in the first 2 hours of active phase of labor, the less rate of cesarean section [p< 0.001]. There was no significant statistical relationship between condition of membranes at the onset of active labor and method of delivery, however there was a significant relationship between oxytocin augmentation and method of delivery [p< 0.001]. In primiparous women with term pregnancy, vaginal delivery would be fairly predictable by observing changes of cervical dilatation and conceptus descent during the first 2 hours of active phase of labor

Association between reproductive factors with breast Cancer risk

Introduction Purpose: unengaged vertex in nulliparous in active labor, as confirmed by some studies is considered as a risk factor in cesarean section Considering the increasing rate of cesarean section in recent years and higher marbidity of cesarean section compared to vaginal delivery we tried to verify the relation between unengaged in vertex nulliparous in active labor and methods of delivery

Material and Methodes: This research was conducted between June 22 1999 to oct 22 2000 in delivery ward in IMAM Reza and HAZRAT ZAYNAB hospital . 100 nulliparous patient with unengaged vertex at the biginning of active labor were considered as the case group 100 other nulliparous patient with engaged vertex were chosen as control group. All the patient were singletons with the fetus between 37 to 42 week . They did not have pelvic contraction and the fetuses were not macrosomic for every patient was filled a questionnaire from the biginning of the active labor to the time of the delivery . The data obtained were analyzed using the fisher test and T test

Results: Of 100 cases of engaged vertex, there were 8 cases of cesarean section and 92 cases of vaginal delivery [Five cases due to fetal distress and three cases due to arrest and protraction disorders]

Of 100 cases of unengaged vertex there were 21 cases of cesarean section and 7 cases of vaginal delivery [9 cases due to fetal distress and 12 cases due to arrest and protraction disorders]

Conclusion: In nulliparous with unengaged vertex the risk of cesarean section increases. In such cases, therefore the need for conscious seach is clearly felt
