Closed glottis pushing is a technique commonly used in childbirth to help a laboring individual expel the baby during the second stage of labor. This method involves taking a deep breath, closing the glottis, and bearing down to increase intra-abdominal pressure. While it can be effective in certain situations, it also carries potential risks and requires proper guidance from healthcare professionals. Understanding the mechanics, benefits, and potential complications of closed glottis pushing is essential for expecting parents, doulas, midwives, and medical students who wish to make informed decisions about labor management and delivery.
What is Closed Glottis Pushing?
Closed glottis pushing, also known as Valsalva maneuver pushing, is a technique in which the laboring individual holds their breath and bears down during a contraction. By closing the glottis-the opening between the vocal cords-the person generates significant intra-abdominal and intra-thoracic pressure. This pressure is transmitted to the uterus, aiding in the downward movement of the baby through the birth canal. The technique contrasts with open glottis pushing, where the laboring person exhales while bearing down, often resulting in more controlled and sustained expulsive efforts.
How Closed Glottis Pushing Works
The mechanics of closed glottis pushing rely on coordinated efforts between breathing, abdominal muscles, and pelvic floor muscles. When the glottis is closed, pressure builds in the chest and abdominal cavity. The diaphragm and abdominal muscles contract, creating a force that helps push the baby downward. This technique can be particularly useful when the baby is in a favorable position and labor is progressing efficiently. However, maintaining the breath hold for too long or pushing excessively can lead to complications for both the birthing person and the baby.
Benefits of Closed Glottis Pushing
Closed glottis pushing can offer certain advantages during the second stage of labor, especially under medical supervision. These benefits include
Effective Force Generation
The Valsalva maneuver produces a strong, short burst of intra-abdominal pressure that can help move the baby more quickly through the birth canal. In cases where labor has slowed or the fetal head is low, this method can sometimes expedite delivery and reduce overall labor duration.
Enhanced Focus During Contractions
Some individuals find that holding their breath and concentrating on bearing down allows them to focus more effectively on the contraction and pushing process. This can provide a sense of control and intentionality, which may reduce anxiety during labor.
Assistance in Instrumental Deliveries
In certain cases, closed glottis pushing may be used in combination with assisted deliveries, such as vacuum or forceps, to provide additional expulsive force. This technique can help healthcare providers manage deliveries where extra effort is needed while maintaining coordination with medical interventions.
Potential Risks and Considerations
Despite its benefits, closed glottis pushing carries potential risks that should be carefully considered. Healthcare providers often weigh these factors before recommending this technique to laboring individuals.
Increased Blood Pressure
Holding the breath and bearing down can cause a temporary spike in blood pressure. For individuals with hypertension or cardiovascular concerns, this increase may be risky and could lead to complications such as fainting, dizziness, or cardiac stress.
Reduced Oxygen Supply
Because the breath is held during closed glottis pushing, oxygen levels in both the birthing person and the baby can decrease temporarily. In some cases, this may contribute to fetal distress or decreased maternal energy, particularly if pushing efforts are prolonged.
Pelvic Floor Stress
Excessive or prolonged Valsalva pushing can increase the strain on pelvic floor muscles, potentially contributing to long-term issues such as incontinence or pelvic organ prolapse. Proper guidance and technique are important to minimize these risks.
Alternative Methods
Open glottis pushing, coached pushing, and spontaneous pushing are alternatives that may reduce some of the risks associated with closed glottis pushing. These methods encourage exhaling while pushing, often resulting in more sustainable effort and improved oxygenation for both mother and baby.
When Closed Glottis Pushing is Recommended
Closed glottis pushing may be recommended in specific scenarios where short, forceful efforts are needed to advance labor. Common situations include
- When labor is prolonged and the baby’s descent has slowed.
- During second stage labor in hospitals where monitoring and support are readily available.
- When an assisted delivery is anticipated, requiring additional pressure for safe extraction.
- For individuals who feel confident and can safely perform the technique under guidance.
Healthcare providers typically evaluate the mother’s health, fetal status, and labor progression before recommending closed glottis pushing to ensure safety and effectiveness.
Tips for Safe Closed Glottis Pushing
To minimize risks and maximize effectiveness, laboring individuals and their support teams should follow several key tips when using closed glottis pushing
Follow Professional Guidance
Closed glottis pushing should always be performed under the supervision of trained medical personnel, such as obstetricians, midwives, or labor nurses. Professionals can provide real-time feedback, monitor the baby’s heart rate, and ensure that pushing is safe.
Use Short, Controlled Pushes
Instead of holding the breath and bearing down for extended periods, it is recommended to use short, controlled pushes during contractions. This approach reduces strain on the cardiovascular system and improves oxygen delivery to both mother and baby.
Stay Hydrated and Rested
Labor can be physically demanding, and closed glottis pushing requires energy and focus. Maintaining hydration and resting between contractions when possible helps sustain strength and reduces fatigue during pushing.
Combine with Breathing Techniques
Integrating proper breathing techniques, such as inhaling deeply before each push and exhaling gradually afterward, can enhance the effectiveness of closed glottis pushing while reducing the risk of oxygen deprivation or excessive pressure.
Closed glottis pushing is a widely recognized technique used during the second stage of labor to assist with the delivery of the baby. By closing the glottis and bearing down, laboring individuals generate significant intra-abdominal pressure to help move the baby through the birth canal. While the technique can be effective, it carries potential risks, including increased blood pressure, reduced oxygen supply, and pelvic floor strain. Safe application requires guidance from medical professionals, short and controlled pushing efforts, and integration with proper breathing strategies. Understanding the mechanics, benefits, and precautions associated with closed glottis pushing empowers expecting parents and their support teams to make informed decisions about labor and delivery, promoting a safer and more positive birth experience.
