Shape and Type of Uterine Contractions at Premature Detachment: Uterine Behavior Abruption Placenta
نویسنده
چکیده مقاله:
Although premature separation of normally implanted placenta is considered the most serious complication of pregnancy, knowledge of uterine behaviour during this condition is meager, on the basis of electronic recording of intra-uterine pressure two type of contraction pattern has been identified. In type I uterine tonus has values below 30mmHg with a frequency of 4-9 contractions per 10 minutes. In type II uterine tonus has a value of 30 mm Hg or more and a higher frequency. Cases falling in type I react to the administration of oxytocin, while those in type II do not. So uterine tonus and contraction frequency appear to be a good indicator of the functional status of uterine mmcle in abruptic placenta and its reactivity to oxytocic agents.

The Shape of Uterine Contractions and Labor Progress in the Spontaneous Active Labor
Background: Dystocia is the most common indication of primary cesarean section. The most common cause of dystocia is uterine dysfunction. In prolonged labor, more attention is usually paid to the fetus and pelvis rather than to the role of uterine contractions in a delivery. Therefore, we decided to determine the relationship between the labor progress and uterine contractions shapes.Methods: I...

Presently, there is no effective treatment for preterm labor. The most obvious reason for this anomaly is that there is no objective manner to evaluate the progression of pregnancy through steps leading to labor, either at term or preterm. Several techniques have been adopted to monitor labor, and/or to diagnose labor, but they are either subjective or indirect, and they do not provide an accur...
