What is a common complication associated with local anesthetic injections?

• A. Hematoma formation
• B. Acute allergic reactions
• C. Severe neuropathy
• D. Thrombosis

Answer: (A)

Hematoma formation is indeed a common complication associated with local anesthetic injections. This condition occurs when there is bleeding into the tissues surrounding the injection site, often due to the puncture of a blood vessel during the injection process. Hematomas can cause swelling, pain, and bruising, which may be more pronounced depending on the location and extent of the injury. In most cases, they resolve on their own without requiring specific treatment, but they can be uncomfortable for patients and may require observation to ensure no further complications arise. Other potential complications, while significant, are less common in the context of routine local anesthetic procedures. Acute allergic reactions can occur but are rare, and the prevalence of such reactions is generally less than that of localized hematoma formation. Severe neuropathy can happen due to direct nerve trauma or prolonged pressure from swelling, yet it is more unusual. Thrombosis, while a serious concern in certain clinical contexts, is not typically associated with local anesthetic injections as a direct complication. Thus, the occurrence of hematoma formation makes it a more frequent and recognizable complication in practice.
