Restricted physical activity can lower blood pressure. The dose is typically increased until contractions occur at two to three minute intervals. The diagnosis of shoulder dystocia is made after delivery of the head. A person viewing it online may make one printout of the material and may use that printout only for his or her personal, non-commercial reference.

Assessment of cervical ripeness.

Dystocia and Augmentation of Labor

Short stature less than 5 ft [ cm]. A maximum of 5 contractions in a minute period with resultant cervical dilatation is considered adequate. Inefficient uterine action should be corrected before attributing dystocia to a pelvic problem. Clinical criteria that confirm term gestation: The preferred agents are methyldopa for prolonged antenatal therapy, and hydralazine, labetalol or nifedipine for peripartum treatment of acute hypertensive episodes.

The fetal forearm or hand is then grasped and the posterior arm delivered, followed by the anterior shoulder. Placing the woman in the left lateral position, administering oxygen, and increasing intravenous fluids may also be of benefit. Induction of labor refers to stimulation of uterine contractions prior to the onset of spontaneous labor. Indications for labor induction: Absolute contraindications to labor induction: Macrosomia has the strongest association.


Hyperstimulation and tachysystole may occur with use of prostaglandin compounds or oxytocin.

See My Options close Already a member or subscriber? The most common adverse effect of hyperstimulation is fetal heart rate deceleration associated with uterine hyperstimulation. A cervical examination should be performed before initiating attempts at labor induction.

See My Options close. The goal of therapy in women without end-organ damage is systolic pressure between and mm Hg and diastolic pressure between 90 and mm Hg. Conditions associated with bleeding from coagulopathy and thrombocytopenia include abruptio placentae, amniotic fluid embolism, augmmentation, coagulation disorders, autoimmune thrombocytopenia, and anticoagulants. Assessment of the fetus consists of estimating fetal weight and position.

Obstetric hemorrhage remains a leading causes of augmentwtion mortality. Walking during labor has not been shown to enhance or impair progress in labor. Fetal imaging should be considered when malpresentation or anomalies are suspected based on vaginal or abdominal examination or when the presenting fetal part is persistently high.

Caution should be exercised to ensure that the fetal vertex is well-applied to the cervix and the umbilical cord or other fetal part is not presenting. Most commonly, size discrepancy secondary to fetal macrosomia is associated with difficult shoulder delivery.

The maneuver consists of rotation of the head to occiput anterior.

Membrane stripping is a widely utilized technique, which causes release of either prostaglandin F2-alpha from the decidua and adjacent membranes or prostaglandin E2 from the cervix. Oxytocin is given intravenously.

A prolonged latent phase is one that exceeds 20 hours in the nullipara or one that exceeds 14 hours in the dystcia.

Causal factors of macrosomia include maternal diabetes, postdates gestation, and obesity. They result in gradual effacement and dilation of the cervix. It can also be performed in anticipation of a difficult delivery.

Twin gestation does not preclude the use of oxytocin for labor augmentation. In nulliparous women, the diagnosis should be considered when the second stage of labor exceeds two hours without regional anesthesia and three hours if anesthesia was used. During the latent phase, uterine contractions are infrequent and irregular and result in only modest discomfort.

A long-acting calcium channel blocker eg, nifedipine or amlodipine can be added as either secondor third-line treatment. Cervidil is a vaginal insert containing 10 mg of dinoprostone in a timed-release formulation. Want to use this article elsewhere? More in Pubmed Citation Related Articles. Uterine atony is the most common cause of postpartum hemorrhage. A prolonged second stage dustocia labor warrants clinical reassessment of the patient, fetus, and expulsive forces.

Dystocia should not be diagnosed until an adequate trial of labor has been achieved. Intermittent auscultation is equivalent to continuous electronic fetal monitoring when performed at specific intervals with a one-to-one nurse-to-patient ratio. A generous episiotomy should be cut. Get immediate access, anytime, anywhere.

Oxytocin may be initiated 30 to 60 minutes after removal of the insert.
