Childbirth is a miraculous journey filled with anticipation and excitement, but sometimes nature needs a little nudge.
Enter the deep transverse arrest technique, a fascinating method that holds the power to manipulate the position of the precious fetal head.
Let’s venture into the realm of this mystical yet effective technique, where four fingers without a thumb become the catalyst for a beautiful birth.
deep transverse arrest
Deep transverse arrest refers to a situation during childbirth where the fetal head becomes lodged in the transverse position, obstructing its descent through the birth canal.
To address this issue, a technique involving the use of four fingers of one hand is employed, with the thumb not inserted.
In cases of right occipitoposterior (ROP) or right occipitotransverse (ROT) positions where the fetal head is anterior, pressure is applied by the ulnar border of the hand.
On the other hand, in left occipitoposterior (LOP) or left occipitotransverse (LOT) positions where the fetal head is posterior, pressure is applied on the parietal bone using the radial border of the hand.
By manipulating the position of the fetal head using these specific pressure points, deep transverse arrest can potentially be resolved, allowing for a smoother progression of childbirth.
Key Points:
- Deep transverse arrest is when the fetal head is stuck in a transverse position during childbirth.
- A technique involving the use of four fingers of one hand is used to address this issue.
- Pressure is applied by the ulnar border of the hand in cases of right occipitoposterior or right occipitotransverse positions.

Deep Transverse Arrest Technique
Deep transverse arrest is a condition that occurs during childbirth when the fetal head fails to descend properly through the birth canal. This can result in prolonged labor and a range of complications for both mother and baby. However, there is a technique that can be employed to address deep transverse arrest and facilitate the safe delivery of the baby. This technique involves using four fingers of one hand, with the thumb not inserted, to manipulate the position of the fetal head.
Using Four Fingers Of One Hand
When facing deep transverse arrest, it is crucial for the obstetrician to utilize the technique of using four fingers of one hand. This enables the obstetrician to position their hand carefully around the fetal head, allowing for the application of gentle pressure and manipulation of the baby’s position. By doing so, the obstetrician can exert greater control and precision in guiding the baby’s descent through the birth canal, thus facilitating a safe and efficient delivery.
The use of four fingers ensures that the pressure is evenly distributed and prevents the application of excessive force. Additionally, it grants the obstetrician the necessary flexibility to adapt to the specific needs of each individual case. This technique effectively addresses various positions of deep transverse arrest, such as right occipitoposterior (ROP) and right occipitotransverse (ROT), as well as left occipitoposterior (LOP) and left occipitotransverse (LOT).
Thumb Not Inserted During Technique
During the deep transverse arrest technique, it is essential for the obstetrician to avoid inserting the thumb into the birth canal. The thumb can disrupt the delicate positioning and lead to further complications. Instead, the four fingers of one hand should be used for the necessary pressure and manipulation.
Excluding the thumb from the technique ensures precise and careful execution. It enables the obstetrician to concentrate solely on the accurate positioning of the fetal head, minimizing the risk of accidental damage to both the mother and baby. By adhering to this guideline, obstetricians can effectively manage deep transverse arrest while promoting favorable outcomes and reducing risks.
Dealing With Right Occipitoposterior (ROP)
Right occipitoposterior (ROP) is a position where the baby’s head is facing the mother’s right side while the baby’s occiput is positioned posteriorly. In cases when ROP and deep transverse arrest are present, the deep transverse arrest technique can be applied to manipulate and guide the baby’s head through the birth canal.
To perform this technique, the obstetrician utilizes the four fingers of one hand to carefully apply pressure anterior to the fetal head. The pressure is directed with the ulnar border of the hand to encourage the proper descent and rotation of the baby’s head. This maneuver facilitates a safer and more efficient delivery.
Improvements:
- The position known as right occipitoposterior (ROP) is characterized by the baby’s head facing the mother’s right side and the baby’s occiput positioned posteriorly.
- In instances where ROP and deep transverse arrest occur, the deep transverse arrest technique is employed to manipulate and guide the baby’s head through the birth canal.
- During the technique, the obstetrician uses the four fingers of one hand to apply careful pressure anterior to the fetal head.
- The pressure is directed using the ulnar border of the hand to facilitate the appropriate descent and rotation of the baby’s head, leading to a safer and more efficient delivery.

Handling Right Occipitotransverse (ROT) Position
Right occipitotransverse (ROT) is a position during childbirth that can lead to deep transverse arrest. It occurs when the baby’s head is facing the mother’s right side, with the occiput positioned transversely. To address ROT and facilitate delivery, the deep transverse arrest technique can be employed.
In this instance, instead of applying pressure anterior to the fetal head, the obstetrician focuses on applying pressure on the parietal bone using the radial border of the hand. Skillfully manipulating the position of the baby’s head allows the obstetrician to guide it through the birth canal and mitigate deep transverse arrest.
- The right occipitotransverse (ROT) position can cause deep transverse arrest during childbirth.
- The deep transverse arrest technique is used to address ROT and facilitate delivery.
- Rather than applying pressure anterior to the fetal head, the obstetrician applies pressure on the parietal bone using the radial border of the hand.
- Skillful manipulation of the baby’s head helps guide it through the birth canal and mitigate deep transverse arrest.
Applying Pressure Anterior To The Fetal Head
Applying pressure anterior to the fetal head is a crucial aspect of the deep transverse arrest technique. This pressure helps to reshape the baby’s head and promotes its proper descent through the birth canal. By exerting careful and controlled pressure, the obstetrician can significantly improve the chances of a successful and safe delivery.
The pressure applied anterior to the fetal head is a crucial step in managing deep transverse arrest. It aids in overcoming obstructions and allows the baby’s head to align correctly within the birth canal. Through skillful manipulation of the position, the obstetrician paves the way for a smoother childbirth experience.
Using Ulnar Border Of Hand For Pressure
During the deep transverse arrest technique, the ulnar border of the hand is the preferred point of contact for applying pressure. This part of the hand provides the necessary stability and control to exert the desired force without causing harm to the mother or baby.
By using the ulnar border of the hand, the obstetrician can effectively distribute the pressure evenly around the fetal head. This approach mitigates the risk of inadvertently applying excessive or uneven pressure, ensuring a more precise manipulation of the baby’s position.
Managing Left Occipitoposterior (LOP) Presentation
Left occipitoposterior (LOP) presentation occurs when the baby’s head is facing the mother’s left side, with the occiput positioned posteriorly. This position can also lead to deep transverse arrest and requires specific techniques to address it.
The deep transverse arrest technique, similar to the technique used for ROP, can be successfully applied in these cases.
Using the four fingers of one hand and gentle pressure applied anterior to the fetal head, the obstetrician can encourage the proper rotation and descent of the baby’s head. This technique aims to reposition the baby into a more favorable position for a successful delivery.
- LOP presentation: baby’s head facing left side, occiput positioned posteriorly
- Deep transverse arrest: potential complication
- Technique similar to ROP
- Four fingers, gentle pressure applied anteriorly to fetal head
- Goal: promote proper rotation and descent for successful delivery
Addressing Left Occipitotransverse (LOT) Position
In the left occipitotransverse (LOT) position, the baby’s head is facing the mother’s left side, with the occiput positioned transversely. To address deep transverse arrest in this position, the obstetrician can utilize the deep transverse arrest technique.
In this technique, the obstetrician applies pressure to the parietal bone by using the radial border of the hand. This manipulation helps in repositioning the baby’s head and facilitates a safe passage through the birth canal. By employing the deep transverse arrest technique, obstetricians can effectively overcome the challenges presented by deep transverse arrest.
Some key points about the LOT position and deep transverse arrest technique are:
- LOT position involves the baby’s head facing the mother’s left side, with transverse occiput positioning.
- Deep transverse arrest is a condition that can occur in the LOT position during childbirth.
- The deep transverse arrest technique involves applying pressure to the parietal bone using the radial border of the hand.
- This technique helps reposition the baby’s head and navigate it safely through the birth canal.
“The deep transverse arrest technique enables obstetricians to guide the baby through the birth canal safely, mitigating the challenges posed by deep transverse arrest.”
Pressuring Posterior To The Fetal Head
In instances of deep transverse arrest, the baby’s head may present posteriorly. To address this situation, the obstetrician can apply pressure posterior to the fetal head. By skillfully manipulating the position with the appropriate amount of pressure, the obstetrician guides the baby’s head through the birth canal.
Managing deep transverse arrest and a posterior presentation requires delicate yet confident application of pressure. With the correct guidance, the baby can be maneuvered into a more favorable position for a smoother and safer delivery.

You may need to know these questions about deep transverse arrest
How do you manage deep transverse arrest?
Deep transverse arrest is a challenging situation that requires careful management. When a contracted pelvis is the underlying cause, the safest approach is to opt for a cesarean delivery. This surgical intervention ensures the well-being of both the mother and the baby. However, if the pelvis is deemed to be adequate, an alternative to consider is a forceps rotation. Careful and skilled maneuvering of the forceps may assist in repositioning the baby for a successful vaginal delivery.
In cases of transverse arrest, oxytocin can be a valuable tool. It can aid in stimulating uterine contractions, addressing uterine inertia that may contribute to the arrest. Additionally, oxytocin may help strengthen the compromised pelvic floor muscles, which can be another cause of transverse arrest. Employing an individualized approach considering the specific circumstances can increase the likelihood of a positive outcome for both mother and baby.
What type of pelvis is deep transverse arrest?
Deep transverse arrest is a condition in which the baby’s head gets stuck at the level of the ischial spines during labor. It is often associated with an Android pelvis, which is the most frequently encountered type of abnormal pelvis. The Android pelvis is characterized by a narrow anterior-posterior diameter, resulting in difficulty for the baby’s head to descend through the birth canal. This type of pelvis can lead to prolonged or obstructed labor, requiring medical intervention to ensure a safe delivery.
What is DTA in Labour?
DTA in Labour refers to deep transverse arrest, a condition where the head only rotates anteriorly by 1/8th of a circle during childbirth, resulting in difficulty in delivery. When faced with this situation, healthcare providers can opt to manually or mechanically rotate the head using rotational forceps such as Kielland Forceps. Following the rotation, delivery of the head can be facilitated either by vacuum extraction or by forceps application. This intervention aims to overcome the obstruction caused by DTA and ensure a safe and successful delivery.
Does deep transverse arrest occur in the pelvis?
Deep transverse arrest can indeed occur in the pelvis when labor is obstructed and the fetal head reaches the level of the ischial spines with the sagittal suture positioned in the transverse diameter of the pelvis. This particular scenario involves the occiput being situated on one side of the pelvis and the sinciput on the other side, with the head poorly flexed. This condition can pose challenges for the progress of labor and may require interventions to assist in the safe delivery of the baby. Understanding and effectively managing deep transverse arrest is crucial to ensure the well-being of both the mother and the baby during childbirth.
