Get immediate access, anytime, anywhere. In the first stage of labor, the diagnosis of dystocia can not be made unless the active phase of labor and adequate uterine contractile forces have been present. Most commonly, size discrepancy secondary to fetal macrosomia is associated with difficult shoulder delivery.

See My Options close. Fetal anomalies such as hydrocephaly, encephalocele, and soft tissue tumors may obstruct labor. No evidence supports routine use of intrauterine pressure catheters for labor management. Clinical pelvimetry can only be dhstocia to qualitatively identify the general architectural features of the pelvis. According to ACOG, a more practical classification is to categorize augmejtation abnormalities as slower-than-normal protraction disorders or complete cessation of progress arrest disorders.

The first stage of labor consists of the period from the onset of labor until complete cervical dilation 10 cm. The fetal forearm or hand is then grasped and the posterior arm delivered, followed by the anterior shoulder.

In multiparous women, the time limit is one hour without anesthesia and two hours if it was administered. This maneuver may be performed prophylactically in anticipation of lf difficult delivery.

The elbow is then swept across the chest, keeping the elbow flexed. Restricted physical activity can lower blood pressure. Maximum total dose administered-during-labor: Local administration of prostaglandins to the vagina or the augmentattion is the augjentation of choice because of fewer side effects and acceptable clinical response.


It is not harmful, and mobility may result in greater comfort and ability to tolerate labor. The time interval between the final dose and initiation of oxytocin should be 6 to 12 hours because of the potential for uterine hyperstimulation with concurrent oxytocin and prostaglandin administration. Ressel Am Fam Physician. Beta-blockers are generally considered to be safe, although they may impair fetal growth when used early in pregnancy, particularly atenolol. The dystocla of oxytocin administration is to stimulate uterine activity that is sufficient to produce cervical change and augmentatiob descent while avoiding uterine dysstocia and dysrocia compromise.

The active phase of labor is characterized by an increased rate of cervical dilation and by descent of the presenting fetal part. If oxytocin is being infused, it should be discontinued to achieve a reassuring fetal heart rate pattern.

The duration of the second stage of labor is unrelated to perinatal outcome in the absence of a nonreassuring fetal heart rate pattern as long as progress occurs.

Email Alerts Don’t miss a single issue. Dystocia should not be diagnosed until an adequate trial of labor has been achieved.

The urethra should be laterally displaced to minimize the risk of lower urinary tract injury. An assistant is requested to apply pressure downward, above the symphysis pubis.

According to ACOG, risk factors for dystocia include epidural analgesia, occiput posterior position, longer first stage of labor, nulliparity, short maternal stature, birth weight, and high station at complete cervical dilation.

Twin gestation does not preclude the use of oxytocin for labor augmentation. A ripening process should be considered prior to use of oxytocin zugmentation when the cervix is unfavorable.

More in Pubmed Citation Related Articles. Complications of labor induction. Removing the PGE2 vaginal insert will usually help reverse the effects of the hyperstimulation and tachysystole.

Immediate preparations should be made for cesarean delivery. Hyperstimulation and tachysystole augentation occur with use of prostaglandin compounds or oxytocin.

Dystocia and augmentation of labor.

Between andthe rate of labor induction doubled from 10 to 20 percent. Gentle upward rotational pressure is applied so that the posterior shoulder girdle rotates anteriorly, allowing it to be delivered first.


Short stature less than 5 ft [ cm]. Clinical criteria that confirm term gestation: Woman with mild, uncomplicated chronic hypertension can be allowed to go into spontaneous labor and deliver at term.

Dystocia and Augmentation of Labor

A cervical examination should be performed before initiating attempts at labor induction. Postpartum hemorrhage is defined as the loss of more than mL of blood following delivery. Labetalol is the preferred agent. Causal factors of macrosomia augmentstion maternal diabetes, postdates gestation, and obesity.

Dystocia is defined as difficult labor or childbirth resulting from abnormalities of the cervix and uterus, the fetus, the maternal pelvis, or a combination of these factors. 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. 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.

Dystocia and Augmentation of Labor

ACE inhibitors should not be augmentatioj in pregnancy. A long-acting calcium channel blocker eg, nifedipine or amlodipine can be added as either secondor third-line treatment. The uterine response to exogenous oxytocin administration is periodic uterine contractions.

This stage is divided into the latent phase and the active phase. Read the full article.

Continuous support augmentatioj labor from caregivers nurses, midwives, or lay persons has several benefits to the patients and newborns without any evidence of harmful effects. The minimal uterine contractile pattern of women in spontaneous labor consists of 3 to 5 contractions in a minute period.
