Changes in Maternal and Fetal Level
To do so leads to changes in maternal and fetal level, of which name a few:
Uterine contractions: are involuntary, are presented in 3 to 5 in 10 minutes on a regular basis during the progression of labor, lasting between 40 to 60 seconds and are accompanied by pain whose intensity is highly variable. The pain of contractions during labor is better tolerated by women who have good information and family support. During labor, the frequency, intensity and duration of contractions will be monitored clinically and / or by electronic monitoring.
Effacement and dilation: As a result of uterine contractions the cervix effaces (thins) and dilates (opens) to allow the fetal head descends gradually through the birth canal. Cervical dilatation defined the onset of labor when it is 3 cm or greater. When complete (10 cm) allows the passage of the fetus by the maternal pelvis. Cervical dilation is controlled by vaginal examination during labor progression in the opinion of professional acting.
Ovular membranes or bag of waters “are membranous structures that contain the fetus and amniotic fluid. Play the role of containment and protection of the fetus normally until they break spontaneously, occasionally artificially by the OB / to during labor. They are strained as a result of increased pressure to produce uterine contractions.
