A 43-year-old white woman presented to the emergency department with confusion, agitation, and progressive dyspnea. Chest x-ray revealed pulmonary edema. ⋯ Her salicylate level was 92.6 mg/dL, and an arterial blood gas revealed a respiratory alkalosis and nonanion gap metabolic acidosis, consistent with salicylate poisoning. Noncardiogenic pulmonary edema is an atypical presentation of salicylate toxicity, and this case highlights the importance of an early toxicology screen to make a time-critical diagnosis and provide specific treatment.

There is controversy regarding needle aspiration for primary spontaneous pneumothorax (PSP), with contradictory recommendations between the American College of Chest Physicians consensus statement (2001), which suggests that needle aspiration has little place in the management of PSP, and the British Thoracic Society guidelines (2010), which recommend that needle aspiration be attempted first for all cases of PSP where drainage is deemed necessary. Studies have shown that there is no significant difference between needle aspiration and tube thoracostomy with regard to safety, rates of immediate success, and early failure and has the advantages of decreasing pain and reducing rates of hospital admission and duration of hospital stay compared with tube thoracostomy. Point-of-care ultrasound (US) can facilitate needle aspiration by decreasing the risk of complications and detect pneumothorax resolution during or re-expansion after the procedure. ⋯ This technique allows the determination of pneumothorax resolution or re-expansion in real time. Point-of-care US may assist in the evaluation and management of spontaneous pneumothorax in the pediatric ED. Ultrasound-assisted needle aspiration may be a safe and less painful option for pediatric ED patients with PSP.
