Needle Decompression - Are we Teaching the Right Location?
- Tension pneumothorax frequently results in circulatory collapse and may lead to cardiopulmonary arrest.
- In the event that tube thoracostomy cannot be immediately performed, traditional teaching is to perform needle decompression in the second intercostal space, mid-clavicular line using a 5-cm angiocath needle.
- Recent literature, however, has challenged the traditional location for needle decompression. In fact, researchers found:
- Needles placed in the second intercostal space often failed to enter the chest cavity and relieve tension physiology.
- Needles placed in the fifth intercostal space in the anterior axillary line were more likely to enter the chest cavity with a lower failure rate.
- Take Home Point: It may be time to reconsider the optimal position for needle decompression of tension pneumothorax.
