In the critical moments following a paediatric cardiac arrest, the quality of chest compressions is the single most important factor in determining a positive outcome. For those seeking professional training with Practical First Aid in London, understanding the nuances of various resuscitation methods is essential. One of the most effective, yet often misunderstood, methods is the encircling technique for infant CPR.
Whether you are a healthcare professional, a childcare provider, or a concerned parent, mastering this specific skill can significantly improve the efficacy of life-saving efforts. In this comprehensive guide, we will explore the mechanics, benefits, and clinical guidelines surrounding the two-thumb encircling hands technique, ensuring you have the knowledge required to act decisively in an emergency.
Understanding Infant Cardiopulmonary Resuscitation (CPR)
Before diving into the specifics of the encircling technique for infant CPR, it is vital to define what we mean by an ‘infant’ in a clinical context. According to the Resuscitation Council UK (RCUK), an infant is a child under the age of one year.
Resuscitating an infant requires a fundamentally different approach than resuscitating an adult or an older child. Their skeletal structures are more flexible, their heart rates are naturally higher, and the primary cause of cardiac arrest is often respiratory failure rather than a primary cardiac event.
Consequently, the technique used for chest compressions must be precise enough to provide adequate circulation without causing internal trauma.
What is the Encircling Technique for Infant CPR?
The encircling technique for infant CPR, formally known as the two-thumb encircling hands technique, is a method of performing chest compressions where the rescuer’s hands encompass the infant’s chest.
In this position, the rescuer places both thumbs on the lower half of the infant’s sternum (the breastbone), while the remaining fingers of both hands wrap around the infant’s torso, supporting the back. The compressions are delivered by pressing the thumbs into the chest while the fingers provide a stable platform against the spine.
The Mechanics of the Two-Thumb Encircling Hands Technique
To perform the technique correctly, follow these anatomical markers:
-
Hand Placement: Place your thumbs side-by-side on the lower third of the infant’s sternum. In very small neonates, the thumbs may need to overlap.
-
Encircling: Wrap your fingers around the infant’s ribcage. Your fingers should meet or overlap behind the infant’s back to provide firm support.
-
Compression Depth: Use your thumbs to depress the sternum by approximately one-third of the depth of the chest (roughly 4 cm or 1.5 inches).
-
Chest Recoil: After each compression, ensure you allow for full chest recoil. This means the chest should return to its original position without your thumbs losing contact with the skin. This allows the heart to refill with blood.
-
Rate: Maintain a steady rhythm of 100 to 120 compressions per minute.
Why Use the Encircling Technique? (The Benefits)
Medical research and clinical simulations consistently show that the encircling technique for infant CPR is superior to the traditional two-finger technique in several key areas:
1. Improved Coronary Perfusion Pressure
The encircling method generates higher blood pressure and better blood flow to the brain and heart. Because the fingers provide back support, the force of the compression is more concentrated and efficient, leading to better coronary perfusion.
2. Consistency of Depth
Rescuers often find it easier to maintain the required 4 cm depth using their thumbs and the leverage of their hands compared to using just two fingers. Consistency is vital during prolonged resuscitation efforts where rescuer fatigue sets in.
3. Reduced Physical Strain
The two-finger technique can lead to rapid fatigue in the fingers and wrist. The encircling technique allows the rescuer to use the stronger muscles of the hands and arms, making it more sustainable during an emergency.
4. Better Intrathoracic Pressure
By “squeezing” the chest from both sides (front and back), the technique creates a more uniform increase in intrathoracic pressure, which helps move blood through the circulatory system more effectively.
When to Use the 2 Thumb Encircling Technique?
The application of this technique depends on the number of rescuers available and the level of training.
-
Two-Rescuer CPR: The encircling technique for infant CPR is the “gold standard” for two-rescuer situations. One person manages the airway and performs rescue breaths, while the other performs compressions using the encircling method. This allows for a seamless transition between breaths and compressions.
-
Healthcare Provider Standard: Most medical professionals are taught this as the primary method for infant resuscitation because of its clinical efficacy.
-
Practical First Aid Training: During our courses in London, we teach this technique to those who may be working in environments where multiple trained staff members are present, such as nurseries, schools, or clinical settings.
Note: If you are a lone rescuer and your hands are too small to encircle the infant’s chest while also maintaining an open airway, the two-finger technique may still be used. However, whenever possible, the encircling technique is preferred.
What is the New CPR Technique for Infants?
The term “new” often refers to the shift in preference within international guidelines. Historically, the two-finger technique (using the index and middle fingers) was taught as the primary method for everyone.
However, recent updates from the Resuscitation Council UK and the International Liaison Committee on Resuscitation (ILCOR) have placed a much heavier emphasis on the two-thumb encircling hands technique.
The “newness” lies in the recommendation that even for single rescuers, if they can successfully perform the encircling technique while managing the infant’s position, it is the preferred method due to the superior physiological outcomes it produces.
Step-by-Step Guide: Performing Infant CPR in the UK
If you encounter an unresponsive infant who is not breathing normally, follow these steps as taught in our Practical First Aid courses:
-
Check the Scene: Ensure the area is safe for you and the infant.
-
Check Responsiveness: Gently tap the infant’s foot and call their name. Do not shake an infant.
-
Shout for Help: If you are alone, shout to attract attention. If someone is with you, ask them to call 999 or 112 and locate an AED (Automated External Defibrillator).
-
Open the Airway: Place one hand on the forehead and very gently tilt the head back into a “neutral” position. Do not overextend the neck.
-
Check Breathing: Look, listen, and feel for normal breathing for no more than 10 seconds.
-
Give 5 Initial Rescue Breaths: This is a crucial step in paediatric CPR. Cover the infant’s nose and mouth with your mouth and deliver five gentle breaths, each lasting about one second.
-
Start Compressions (Encircling Technique):
-
Place your thumbs on the lower third of the sternum.
-
Encircle the chest with your fingers.
-
Perform 30 compressions (if you are a layperson) or 15 compressions (if you are a healthcare professional/advanced rescuer).
-
-
Continue CPR: Follow a ratio of 30 compressions to 2 rescue breaths (standard) or 15:2 (advanced/professional) until help arrives or the infant shows signs of life.
Common Pitfalls and How to Avoid Them
Even with the best intentions, errors can occur during high-stress situations. Here is how to ensure your encircling technique for infant CPR remains effective:
-
Avoid “Leaning”: Do not rest your weight on the infant’s chest between compressions. Full recoil is essential for the heart to fill with blood.
-
Finger Placement: Ensure your fingers are not squeezing the sides of the ribs too hard; the pressure should be directed from the thumbs toward the spine.
-
Depth vs. Force: Do not be afraid to compress the chest. Many people fail to compress deeply enough (4 cm) out of fear of hurting the infant. Remember, CPR is a life-saving intervention.
-
Hand Position: Ensure your thumbs are not too high (on the upper sternum) or too low (on the xiphoid process/abdomen). Aim for the lower half of the breastbone.
FAQs: Encircling for Infant CPR
What is the encircling technique for CPR?
It is a method used specifically for infants where the rescuer wraps their hands around the infant’s torso, using both thumbs to compress the breastbone while the fingers support the back.
What is the correct technique for CPR on an infant?
The correct technique involves starting with 5 rescue breaths, followed by chest compressions at a depth of 4 cm. For the best results, the two-thumb encircling hands technique is recommended, especially with two rescuers.
When to use the 2 thumb encircling technique?
It should be used whenever you are performing CPR on an infant (under 1 year old), particularly when there are two rescuers or when the rescuer’s hands are large enough to safely encircle the chest.
What is the new CPR technique for infants?
The “new” standard emphasises the two-thumb encircling hands technique over the two-finger method due to its ability to provide better blood flow and more consistent compression depth.
