Physicians, advanced practice nurses, nursing personnel, and midwives must be aware of what constitutes normal versus abnormal labor.
Without proper skills and strategies, appropriate management cannot occur, and poor outcomes become likely for birthing mothers and their neonates. Discerning different types of abnormal labor will allow for proper management.
This will decrease morbidity and mortality and improve patient outcomes. This activity characterizes normal versus abnormal labor and encourages the usage of protocols specific to the facility in which the labor is occurring. This activity highlights the critical role of the interprofessional birth team in providing optimal care and counseling to the birthing mother and her infant.
Objectives: Describe what happens in each state of normal labor. Identify the abnormalities that can be picked up on a fetal heart rate strip. Explain how the uterine activity is assessed and identify the target number of contractions and the target duration of each contraction during normal labor.
Normal labor is characterized by regular and painful uterine contractions that conclude in progressive labor. A discussion on abnormal labor patterns is reviewed as abnormalities of the first stage cervical dilation to complete cervical dilation and the second stage descent of the presenting part leading to delivery of the baby. The third stage of labor describes the expulsion of the placenta. First and second-stage abnormalities are described either as protraction disorders which means that delivery is progressing but is lower than normal or as arrest disorders complete cessation in progress.
Abnormal third-stage labor meriting intervention is placenta retention beyond 30 minutes, as most third stages are concluded within the first 10 to 20 minutes of delivery. Normal labor is characterized by regular and painful contractions that conclude in delivering the fetus and placenta.
Labor is divided into three stages and subsequent phases within each stage:. Abnormal labor patterns in the first and second stage are defined as either protraction or arrest disorders. Protracted labor stages indicate that labor is progressing but at a slower pace than expected. Arrest disorders indicate the complete cessation of the progress of labor. The following criteria should be kept in mind when labeling the labor as. There is no appropriate length defined for the diagnosis.
However, the following criteria can be utilized in the presence of favorable maternal and fetal condition:. The size of the fetus and the capacity of the maternal pelvis are tested as uterine contractions provide propulsion. However, labor abnormalities due to unfavorable fetal pelvic dynamics lead to true dystocia requiring a cesarean delivery.
The trend toward more cesarean sections in the developed countries has drawn attention to initiatives to minimize primary cesarean sections.
In this regard, guidelines have been developed to guide more conservative management of the first and second stages of labor abnormalities Obstetric care consensus: safe prevention of the primary cesarean delivery-ACOG and SMFM, March After delivery of the baby, the third stage of labor opens the risk for postpartum hemorrhage leading to blood transfusions and maternal morbidity.
Increased and appropriate use of blood transfusions, as well as surgical approaches such as peripartum hysterectomy and compression sutures, have contributed favorably to this statistic. Friedman originally established the labor curve for the first stage of labor; however, it has since been contemporized by Zhang et al.
It is best to defer amniotomy or neuraxial anesthesia, which brings a commitment to delivery and limits the scope of conservative management. In the second stage of labor, in the absence of neuraxial anesthesia, the nulliparous abdomen may be allowed to push for at least 3 hours. Additionally, voluntary pushing in the second stage in women with an epidural may be allowed when the station of the fetal head is at or below the ischial spines. Usually, histopathology is used for scenarios where postpartum hemorrhage has occurred.
When a hysterectomy is performed for postpartum hemorrhage, the histopathology may return consistent with morbidly adherent placenta such as placenta accreta, increta, or percreta.
On occasion, the placental histopathology may return as chorioamnionitis with our without funisitis , which may be associated with postpartum atony leading to hemorrhage.
Oxytocin is a key pharmacologic agent in the correction of abnormal labor patterns. Although oxytocin's first clinical usage was described in for postpartum hemorrhage, its molecular structure remained elusive until , and 1 year later, it became commercially available.
Exogenous oxytocin responsiveness typically commences at 20 weeks and improves with advancing gestational age until 34 weeks, when it appears to stabilize. During spontaneous labor, the blood oxytocin concentration remains stable; however, the responsiveness increases.
Oxytocin has a short plasma half-life between 3 to 6 minutes. It is shown that oxytocin takes approximately 40 minutes to reach a steady-state of plasma concentration; however, clinically, it could be adjusted every 30 minutes. Oxytocin is utilized as a continuous intravenous administration using an infusion pump.
This allows continuous, precise control of the dosage. Standard institutional protocols are required to minimize adverse oxytocin administration.
Of note, oxytocin-induced myometrial receptor desensitization has been demonstrated in animals; its clinical relevance is unknown. As placental perfusion occurs between contractions tachysystole six or more contractions in a minute window averaged over 10 minutes , it should be avoided as it may impact fetal condition if uncorrected.
Maternal hyponatremia occurs only in extended exposures to a high oxytocin dose, especially if administered in hypotonic solutions. This is based on its structure is similar to vasopressin in some regard, and thus oxytocin cross-reacts with the renal vasopressin receptors.
Hypotension has been shown to occur with bolus IV administrations. Symptoms for the onset of preterm labor are reviewed, including a history of contractions that are progressively stronger and any history of leakage of fluid or passage of a mucous plug. Asking about recent vaginal bleeding is always a significant inquiry to exclude concerns for placental abruption.
An abdominal examination is a key component of an obstetric exam as it provides an estimated fetal weight of the fetus and informs the provider of the fetal presentation and the descent of the presenting part into the pelvis. The continuous monitoring of the external fetal heart rate provides insight into fetal well-being.
A manual vaginal exam to evaluate maternal bony pelvis capacity and cervical dilation, as well as fetal pelvic dynamics, occurs at intervals. The uterine activity is assessed by external tocometry and targeted at 3 to 5 contractions in the minute window.
The contractions should last 30 to 40 seconds to be effective. Internal intrauterine pressure assessment using a catheter could be utilized, in which case marked medial units are used and targeted at more than Montevideo units in a minute window. The monitoring of uterine contractions should be continuous during labor. The assessment of the fetal heart rate could be performed utilizing external or internal fetal heart rate monitoring.
In the interpretation of the fetal heart rate strip millimeters considered are baseline viability, basal heart rate, cardiac accelerations or decelerations, endocrine activity.
Strip abnormalities are characterized based on consideration of the above parameters. The obstetric partogram is a composite graphic record of labor progress. The World Health Organization WHO recognizes this status as useful labor management that adequately draws attention to excessively prolonged labor. Most labor and delivery units will have an established protocol for the administration of oxytocin that entails the administration of the proper medication and dosage, as well as criteria for an incremental increase as clinically warranted.
Such protocols allow collaborative care between the nursing staff and the obstetrician. Abnormal labor can be a daunting experience for women, especially during the first birth.
As the labor progresses, the practitioners may advise rest and analgesia. During labor complications, cesarean deliveries can be a life-saving procedure and may become medically necessary. Cesarean section rates among the nulliparous, singleton, term gestation, and vertex presentation NSTV are currently trending in most institutions and states.
Diligent management of labor aspires to minimize variation between providers. As an example, California aspires to reach its target rate of Racial disparities such as non-Hispanic black women having disproportionately higher cesarean delivery also deserve an inquiry.
The best labor-management requires a coordinated interprofessional effort between trained obstetric nurses, midwives, and providers. Labor is a dynamic process and the decision of practitioners may change depending on the maternal and fetal factors.
Since there is always a gray zone in treatment options, t is mandatory to include the patients in their treatment planning. Psychological and emotional support should also be provided, as these women are likely to undergo post-partum blues. Team management may lower the average cesarean section rates and improve outcomes.

Labor is a sequence of uterine contractions that results in effacement and dilatation of the cervix and voluntary bearing-down efforts, leading to the expulsion per vagina of the products of conception. Delivery is the mode of expulsion of the fetus and placenta. Labor and delivery is a normal physiologic process that most women experience without complications.
This means your cervix has opened completely in preparation for childbirth. The second stage is the active stage, during which you begin to push downward. It starts with complete dilation of the cervix and ends with the birth of your baby. The third stage is also known as the placental stage. This stage begins with the birth of your baby and ends with the completed delivery of the placenta. Most pregnant women go through theses stages without experiencing any problems. Some women, however, may experience abnormal labor during one of the three stages of labor.

Background: Modified WHO partograph is graphical record of maternal and foetal data during progress of labour entered against time on single paper sheet. Entire labour can be interpreted in a glance on the photograph. It helps to detect abnormal progress of labour. It guides obstetrician to decide about the need for augmentation of labour or termination of pregnancy either by instrumental delivery or LSCS and avoids prolong labour before obstruction. The objectives were to study the course of normal and abnormal labour and to evaluate the maternal and perinatal outcome in normal and abnormal labour.
The anterior wall at the pubic symphysis measures approximately 5 cm, and the posterior wall measures approximately 10 cm. The pelvic inlet is bounded laterally by the iliopectineal lines, which can be traced anteriorly along the pectineal eminence and pubic crest to the symphysis. The posterior boundary is composed of the sacrum at the level of the iliopectineal lines.

Беккер обернулся как во сне. - Senor Becker? - прозвучал жуткий голос. Беккер как завороженный смотрел на человека, входящего в туалетную комнату. Он показался ему смутно знакомым. - Soy Hulohot, - произнес убийца. - Моя фамилия Халохот. - Его голос доносился как будто из его чрева.
Он немного постоял, наслаждаясь ярким солнцем и тонким ароматом цветущих апельсиновых деревьев, а потом медленно зашагал к выходу на площадь. В этот момент рядом резко притормозил мини-автобус. Из него выпрыгнули двое мужчин, оба молодые, в военной форме. Они приближались к Беккеру с неумолимостью хорошо отлаженных механизмов. - Дэвид Беккер? - спросил один из .
Это девушка. Она стояла у второй входной двери, что была в некотором отдалении, прижимая сумку к груди. Она казалось напуганной еще сильнее, чем раньше.
Или это его подвинули. Голос все звал его, а он безучастно смотрел на светящуюся картинку. Он видел ее на крошечном экране. Эту женщину, которая смотрела на него из другого мира.
Заметано. - Ну вот и хорошо. Девушка, которую я ищу, может быть. У нее красно-бело-синие волосы.

Obstructed labour , also known as labour dystocia , is when the baby does not exit the pelvis during childbirth due to being physically blocked, despite the uterus contracting normally.
