What are the abnormal uterine action

abnormal uterine action are numerous and sometimes lead to confusion. There are basically two groups of abnormal uterine action that may cause dystocia. The resting uterine muscle tone may be poor (hypotonic) and result in feeble or no contractions, or the muscle tone may be high (hypertonic).

How do uterine contractions happen?

Labor contractions are the periodic tightening and relaxing of the uterine muscle, the largest muscle in a woman’s body. Something triggers the pituitary gland to release a hormone called oxytocin that stimulates the uterine tightening. It is difficult to predict when true labor contractions will begin.

Why does uterus contract?

Primary. The uterus contracts to expel menstrual blood; the force of the contractions can temporarily cause ischemia by occluding uterine blood supply. Excessive production of vasopressin causes contraction of the smooth muscle of the uterus and the small muscles within the blood vessels.

What is uterine contraction and retraction?

Contractions (tightening) and retraction (shortening) of myometrial muscle fibres increase in length, strength and frequency as labour progresses. The mucous plug (show) is expelled as the cervix opens and the membrane sac (amnion and chorion) often spontaneously ruptures, allowing amniotic fluid to drain.

What causes uterine contractions during pregnancy?

Contractions occur in pregnancy when you have a certain level of oxytocin flowing in your blood. 1 This can be very normal, like labor, when your body and your baby’s brain release oxytocin to stimulate contractions for labor.

Neither uterine size, shape or position is permanently fixed. Intermittent myometrial contractions and changes in uterine shape and position are normal during pregnancy.

What causes hypotonic uterine action?

Hypotonic contractions occur after administration of analgesia, bowel or bladder distention, if the uterus is overstretched due to multiple gestation, a large fetus, hydramnios, or a uterus that is lax from grand multiparity.

What is hypertonic uterine action?

Uterine hyperstimulation or hypertonic uterine dysfunction is a potential complication of labor induction. This is displayed as Uterine tachysystole- the contraction frequency numbering more than five in a 10-minute time frame or as contractions exceeding more than two minutes in duration.

How do you manage hypertonic uterine contractions?

Hypertonic uterine dysfunction is difficult to treat, but repositioning, short-acting tocolytics (eg, terbutaline 0.25 mg IV once), discontinuation of oxytocin if it is being used, and analgesics may help.
