title: Meralgia paresthetica: an unusual complication of post-cesarean analgesia.
abstract: Intramuscular (IM) injections may be associated with nerve injury, classically the sciatic nerve after intragluteal injection. We describe an unusual injury of the lateral femoral cutaneous nerve following an IM injection of 100 mg meperidine and 25 mg promethazine in the anterolateral right thigh. Although the thigh is advocated as a relatively safe site for IM injection, iatrogenic neuropathy may result. Awareness of the anatomy of the lateral femoral cutaneous nerve and avoiding injections into a partially anesthetized extremity may decrease the likelihood of recurrences.
