What is the most common intervention for hypertonic uterine dysfunction?
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.
What are the characteristics of hypertonic uterine dysfunction?
Hypertonic uterine dysfunction refers to a labor with uterine contractions of poor quality that are painful, are out of proportion to their intensity, do not cause cervical dilation or effacement, and are usually uncoordinated and frequent (see Table 14-4).
What causes hypertonic uterine dysfunction?
Inappropriately high concentrations of oxytocin can cause uterine hypertonus, when the uterus does not relax between contractions, and fetal distress can occur.
What are the signs and symptoms of hypotonic uterine contractions?
- The number of uterine contractions in hypotonic contractions is unusually slow or infrequent.
- There are only two or three contractions occurring within a 10-minute period.
- The strength of contractions does not rise above 10 mmHg, and they occur mostly during the active phase of labor.
What medication might be used to treat hypotonic dysfunction in labor?
Oxytocin is the medication of choice for augmenting contractions.
How is hypotonic uterine dysfunction treated?
The diagnosis is made by palpation and timing the length of contractions. Repeated vaginal examination will demonstrate a cervix which fails to dilate. Contractions may be strengthened by rehydration, relaxation (e.g. by epidural anaesthesia), rupture of the membranes and the use of intravenous syntocinon.
How do you manage hypertonic uterine contractions?
What problems can result from uterine hyperstimulation?
Uterine hyperstimulation may result in fetal heart rate abnormalities, uterine rupture, or placental abruption. It is usually treated by administering terbutaline.
What is hypotonic uterine dysfunction?
Hypotonic labor is a dysfunction in the propulsive power of the uterus that presents as an abnormal labor pattern resulting in prolonged or protracted delivery, which is a common indication for primary cesarean section. Management options include supportive measures, medical treatment, and surgical interventions.
What are the 4 abnormalities of labor in relation to power?
The diagnosis of abnormal labor (dystocia) has four major etiologic categories: (1) the “passage,” or pelvic architecture; (2) the “passenger,” or fetal size, presentation, and position; (3) the “powers,” or uterine action and cervical resistance; and (4) the “patient” and “provider.”
Is uterine rupture painful?
The primary symptoms of a ruptured uterus are acute pain in the abdominal area (from the location of the rupture) and sudden, excessive vaginal bleeding from internal hemorrhaging caused by the rupture. When the rupture occurs during labor it may cause contractions to slow down or lose intensity.
What is the cause of hypotonic uterine dysfunction?
Hypotonic labor is an abnormal labor pattern, notable especially during the active phase of labor, characterized by poor and inadequate uterine contractions that are ineffective to cause cervical dilation, effacement, and fetal descent, leading to a prolonged or protracted delivery.
Does uterine prolapse affect sexual function?
Uterine prolapse can affect sexual function. One way it can do this is by causing pain during intercourse. It can also interfere with sexual function by causing decreased tone of the vaginal canal and by limiting penetration.
What is definition of hypotonic uterine contraction?
Hypotonic uterine contraction (inertia): Hypotonic labour is defined as less than 3 contractions of mild to moderate intensity occurring in a 10 minute period during the active phase of labour. Cervical dilatation and descent of the fetus slow greatly or stop.
What is hypotonic dysfunction?
Hypotonic Uterine Dysfunction. Uterine dysfunction that typically occurs during the active phase of labor, after the cervix has dilated to more than 4 cm. Contractions are usually irregular and are not forceful enough to dilate cervix at a satisfactory rate, which will lead to prolonged labor.
What is abnormal uterine contractions?
This condition is often called irritable uterus (IU). IU contractions are much like Braxton-Hicks, but they can be stronger, occur more frequently, and don’t respond to rest or hydration. These contractions are not necessarily normal, but they also aren’t necessarily harmful.
