Topical hemostatic powder is a mineral powder that forms an adherent barrier and coagulates active bleeding in the gastrointestinal (GI) tract. Hemospray is the first hemostatic powder approved by the Food and Drug Administration (FDA) in the United States. Hemospray has been increasingly used to manage GI bleeding. However, data on the adverse events of hemostatic powders are lacking. Therefore, we aim to report and analyze adverse events associated with Hemospray using the FDA's "Manufacturer and User Facility Device Experience" database.
We analyzed the postmarketing surveillance data from the FDA's Manufacturer and User Facility Device Experience database for Hemospray, initially known as TC-325, from June 2018 through April 2022. Results of the search were classified into device-related technical issues, patient-related adverse events and health care staff-related adverse events.
Five hundred two medical device reporting claims were identified from June 2018 through April 2022. Seven duplicate claims were identified, and some claims included more than one event type. Therefore, there were 558 device-related problems, 28 patient-related adverse events, and 2 adverse events in health care staff members. The most common device-related problems were activation failure or failure to fire (n = 385, 70.0%) and obstruction of carbon dioxide flow (n = 121, 21.7). The most common patient-related adverse events included tissue injury or bleeding (n = 21) and perforation (n = 5).
Although Hemospray is a valuable tool in the armamentarium for endoscopists in managing GI bleeding, endoscopists must be mindful of deice-related problems and potential patient-related adverse events.
