What is the recommended management for retained needle fragments in soft tissue?
Three-dimensional CT scanning to identify the location of the retained needle fragment, followed by removal by an Oral and Maxillofacial surgeon in the operating theater under general anesthesia.
What are the preventive measures recommended to avoid needle breakage during local anesthesia administration?
- Do not use short needles for inferior alveolar nerve block in adults or larger children. 2) Do not use 30-gauge needles for inferior alveolar nerve block in adults or children. 3) Do not bend needles when inserting them into soft tissue. 4) Do not insert a needle into soft tissue to its hub, unless it is absolutely essential for the success of the injection.
What is the significance of needle breakage during local anesthesia administration?
Needle breakage per se is not a significant problem if the needle can be removed without surgical intervention. However, the needle fragment remaining in the tissue poses a risk of serious damage being inflicted on the soft tissues for as long as the fragment remains.
Why should short needles not be used for inferior alveolar nerve block in adults or larger children?
Short needles should not be used for inferior alveolar nerve block in adults or larger children to prevent needle breakage and the risk of retained needle fragments in the soft tissue.
What imaging technique has been recommended for identifying the location of retained needle fragments?
Three-dimensional CT scanning has been recommended to identify the location of the retained needle fragment.
