Psychology of birthPsychology of birth

The progress of labor and birth can be adversely affected maternal fear and tension

Norepinephrine and epinephrine may stimulate both alpha and beta receptors of the myometrium and interfere with the rhythmic nature of labor

Anxiety can also increase pain perception and lead to an increased need for analgesia amp anesthesia

The progress of labor and birth can be adversely affected maternal fear and tension

Norepinephrine and epinephrine may stimulate both alpha and beta receptors of the myometrium and interfere with the rhythmic nature of labor

Anxiety can also increase pain perception and lead to an increased need for analgesia amp anesthesia

Measuring diagonal conjugate

Insert two fingers into the vagina until they reach the sacral promontory

The distance from the sacral promontory to the exterior portion of the symphysis is the diagonal conjugate and should be greater than 115 cm

Unengaged fetal head

bull Feel the ischial spines for their relative prominence or flatness

bull Ischial prominence narrows the transverse diameter of the pelvis

bull Feel the pelvic sidewalls to determine whether they are parallel (OK) diverging (even better) or converging (bad)

bull Narrow sacrosciatic notch

Measure the bony outlet by pressing your closed fist against the perineum

The progress of labor and birth can be adversely affected maternal fear and tension

Norepinephrine and epinephrine may stimulate both alpha and beta receptors of the myometrium and interfere with the rhythmic nature of labor

Anxiety can also increase pain perception and lead to an increased need for analgesia amp anesthesia

Insert two fingers into the vagina until they reach the sacral promontory

The distance from the sacral promontory to the exterior portion of the symphysis is the diagonal conjugate and should be greater than 115 cm

Psychology of birthPsychology of birth

The progress of labor and birth can be adversely affected maternal fear and tension

Norepinephrine and epinephrine may stimulate both alpha and beta receptors of the myometrium and interfere with the rhythmic nature of labor

Anxiety can also increase pain perception and lead to an increased need for analgesia amp anesthesia
