Abnormal Uterine Contraction

Dystocia Uterine


Presentation

  • Brow presentationBrow presentations usually are transient fetal presentations with deflexion of the fetal head. 25 3. Face presentationIn face presentation, the fetal head is fully deflexed from the longitudinal axis. 4.[powershow.com]

Pelvic Mass
  • Other anatomic abnormalities of the reproductive tract may cause dystocia is soft tissue dystocia may be caused by uterine or vaginal congenital anomalies, scarring of the birth canal, pelvic masses, or low implantation of the placenta. 24 --Abnormalites[powershow.com]
  • Uterine myomas are the most common pelvic masses associated with dystocia. They may obstruct the birth canal or cause malpresentation of the fetus.[glowm.com]

Regular Uterine Contractions
  • uterine contractions in normal labor are expulsive power to deliver the fetus.[omicsonline.org]
  • Prolonged Latent Phase The latent phase of labor begins with the onset of regular uterine contractions and extends to the beginning of the active phase of cervical dilatation.[powershow.com]

Bladder Distention
  • Other possible causes of upper genital tract dystocia include ovarian tumors, bladder distention, a pelvic kidney, excess adipose tissue, uterine malposition, and cervical stenosis or neoplasm.[glowm.com]

  • DIFFERENTIALS Other Problems to be Considered: False labor Placental abruption Premature labor WORKUP Lab Studies: No specific laboratory studies are used to assess abnormal labor.[www1.cgmh.org.tw]

Treatment

Prognosis

  • In the absence of fetopelvic disproportion, conservative management, consisting of support and close observation, and therapy with oxytocin augmentation both carry a good prognosis for vaginal delivery. 14 3.[powershow.com]
  • In the developing nations pelvimetry, preferably by CT scan (if available), still has a place to enable the obstetrician to make a decision about a vaginal delivery, but this prognosis is not particularly accurate, as different observers attach different[clinicalgate.com]
  • Prognosis: The prognosis of subsequent pregnancies depends on the cause for abnormal labor. For example, if it occurs from macrosomia, the next infant may not be macrosomic.[www1.cgmh.org.tw]
  • Encephaloceles, which carry a poor prognosis, are usually fragile and may rupture during delivery. Potentially viable conjoined twins require delivery by cesarean section.[glowm.com]

Pathophysiology

  • Keywords: A fundamental problem in developing therapeutic interventions for uterine dysfunction is that the electrical profile of the myometrium, and how it changes in physiological, let alone pathophysiological, situations is unknown.[scitechnol.com]
