Case Reports
Decreased Clinical Toxicity and Two-Phase Elimination Kinetics Observed After Intravenous Iron Sucrose Overdose.
Management of oral iron overdoses is well-established, but there is limited literature regarding intravenous iron sucrose overdoses. Indications for administering deferoxamine after oral iron overdoses include clinical signs and symptoms of toxicity, along with a serum iron concentration ≥ 500 μg/dL. Reported signs and symptoms of iron sucrose overdose do not appear to correlate with those of oral iron overdoses. ⋯ We present a case of intravenous iron sucrose overdose in a clinically well-appearing patient with a presenting serum iron concentration that was several times higher than the usual threshold concentration for initiating deferoxamine treatment. A 21-year-old woman presented to the emergency department after an accidental intravenous iron sucrose overdose. The patient received a home infusion of 1000 mg iron sucrose, which was five times the prescribed dose. Her presenting serum iron concentration was 1799 μg/dL, with bicarbonate and anion gap both within normal limits and an unremarkable physical examination. Because she did not have evidence of severe iron toxicity, she was treated supportively and deferoxamine was not administered. Her serum iron concentration decreased below the toxic range over the next 14 h, and she was discharged home the next day. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: This patient was managed successfully with expectant care alone, suggesting that iron sucrose overdose has much lower toxicity than oral iron salt overdose. This discrepancy between measured iron concentrations and clinical presentation may be explained by the elimination kinetics of iron sucrose having separate redistribution and elimination phases.

Distal forearm fractures are a commonly encountered injury in the emergency department (ED), accounting for 500,000 to 1.5 million visits and 17% of ED fractures. The evaluation and management of these fractures frequently employs x-ray studies, conscious sedation, closed reduction, and splinting. Point-of-care ultrasound (POCUS) can offer significant benefit in the diagnosis and management of these common injuries. ⋯ Distal forearm fractures are common, and the emergency physician should be adept with the evaluation and management of these injuries. POCUS can be a reliable modality in the detection of these fractures and can be used to facilitate analgesia and augment success of reduction attempts. These techniques may decrease length of stay, improve patient pain, and decrease reduction attempts.

Focused transesophageal echocardiogram (TEE) can be a valuable tool for emergency physicians (EP) during cardiac arrest. ⋯ This simplified flipped conference curriculum can train EM residents to competently perform TEE in a simulated environment.

Case Reports
Trocar site hernia after laparoscopy: Early recognition prevents catastrophic sequelae.
Trocar site hernia is a rare but potentially serious complication of laparoscopic surgery that may lead to bowel incarceration and strangulation. Prompt diagnosis by emergency physicians facilitates timely intervention that prevents bowel necrosis. We report a case of trocar site hernia presenting to the emergency department (ED) with abdominal pain that was correctly diagnosed and promptly managed. ⋯ A 25-year-old woman, gravida 2, abortion 2, underwent outpatient surgery and laparoscopic removal of a ruptured right-sided tubal pregnancy without any intraoperative difficulties. However, 48 h later, she presented to the ED complaining of acute abdominal pain and nausea. Computed tomography revealed a loop of small bowel herniating through a 12-mm right lower quadrant trocar site defect in the fascia. She was taken back to the operating room, where the computed tomography findings were confirmed and the entrapped bowel was successfully reduced and the fascial defect repaired. The patient was discharged home feeling much improved. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: Trocar site hernia is a rare but potentially dangerous complication that can present with acute symptoms or be asymptomatic if late in onset. Intestinal necrosis begins as soon as 6 h after constriction of blood flow to entrapped bowel, so timely intervention is critically important. Therefore, trocar site hernias should be considered in patients presenting with abdominal complaints after laparoscopic surgery and included in the differential diagnosis of bowel obstruction.
