Summary
A new gelatin hemostatic sponge rapidly stops bleeding, outperforming existing devices. This biocompatible and resorbable sponge shows promise for managing surgical bleeding and acute injuries.
Area of Science:
- Biomaterials Science
- Surgical Innovation
- Hemostasis Research
Background:
- Managing substantial surgical bleeding in oto-rhino-laryngology (ENT) requires effective hemostatic agents.
- Existing hemostatic devices have limitations in speed and efficacy.
Observation:
- A novel hemostatic sponge composed of chemically cross-linked gelatin was developed.
- The sponge features high pore density, reduced ligaments, and nanoscale surface roughness.
Findings:
- In vitro blood uptake was 2-3 times faster than comparative devices.
- The gelatin sponge induced hemostasis in an in vitro vein model in under a minute.
- Rapid hemostasis was achieved in a patient with pharyngeal angiofibroma bleeding, despite anticoagulant therapy.
Implications:
- The novel gelatin sponge demonstrates superior hemostatic performance, potentially due to enhanced capillary action and fibrinogen anchoring.
- Its biocompatibility and resorbability (within 2 weeks) allow it to be left in situ.
- This hemostatic matrix offers a promising solution for patients with epistaxis and other severe bleeding conditions.
