Unexpected negative-pressure pulmonary edema after tracheostomy: two case reports.
Article in JA clinical reports, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundNegative-pressure pulmonary edema (NPPE) often develops with upper airway obstruction, and is uncommon in secured airways, for example, after tracheostomy. Herein, we report two cases of NPPE post-tracheostomy. CASE PRESENTATION: Case 1: A 69-year-old man underwent prophylactic tracheotomy for possible airway obstruction secondary to glottic carcinoma. Two hours after awakening from general anesthesia, he had difficulty expectorating and developed NPPE due to airway secretions obstructing the tracheostomy tube. Case 2: An 11-year-old boy was admitted to the intensive care unit for continuous hemodiafiltration on a ventilator under sedation. On the 76th day, the day after the tracheostomy was performed, the patient developed patient-ventilator asynchrony due to sedative withdrawal syndrome. The postulated primary mechanism was functional airway obstruction due to patient-ventilator asynchrony.
conclusionThese cases highlight the need to consider NPPE, even in patients with an airway secured with a tracheostomy.
