Upper limb nerve injuries caused by intramuscular injection or routine venipuncture

ABSTRACT

The reported cases of upper limb nerve injury followed by needle procedure such as intramuscular injection or routine venipuncture are rare. However, it should not be overlooked, because neurological injury may cause not only minor transient pain but also severe sensory disturbance, hand deformity and motor dysfunction with poor recovery. Recognizing competent level of anatomy and adept skill of needle placement are crucial in order to prevent this complication. If a patient notices any experience of abnormal pain or paresthesia during the needle procedures, an administrator should be alert to the possibility of nerve injury and should withdraw the needle immediately. Careful monitoring of the injection site for hours is required for early detection of nerve injury.
