Study Notes

HEMOBLAST Application in Cardiac Procedures

HEMOBLAST is a novel hemostatic powder consisting of porcine collagen, bovine chondroitin sulfate, and human pooled plasma thrombin.
This study aimed to describe application techniques of HEMOBLAST.
This study was a prospective, randomized controlled trial.
HEMOBLAST was used in 24 initial cardiac procedures including LVAD insertions, lung transplants, heart transplants, aortic valve replacements, coronary artery bypass grafting and mitral valve repair.
Hemostasis was achieved in all 24 cases.
There were no instances of mediastinitis, sternal infections, allergic reactions, or 30-day mortality.
HEMOBLAST was used successfully for treating mediastinal bleeding in a re-operative procedure in a patient on antiplatelet agents and sternal bleeding during an LVAD insertion.
HEMOBLAST is easy to use, can cover large or small surgical areas, and does not require additional applicators or pressured gases.
HEMOBLAST is applied by rapidly blotting excess blood with a dry pad, sponge, or suction, then applying the powder to the target site to ensure complete coverage.
After HEMOBLAST application, a wet lap pad is applied for 3 minutes to exert pressure.
HEMOBLAST was used in various cardiac procedures to reduce bleeding and improve outcomes.
This study provides a description of the best practices for applying HEMOBLAST.
More studies are planned to determine the effectiveness of HEMOBLAST on surgical blood loss, morbidity, and blood conservation.

HEMOBLAST: Mechanism of Action

HEMOBLAST's main components (collagen, chondroitin sulfate, and thrombin) promote hemostasis through various mechanisms.
Collagen acts as a scaffold, attracting platelets, and triggering the coagulation cascade.
Chondroitin sulfate helps to maintain the structural integrity of the hemostatic plug and may also have anti-inflammatory properties.
Thrombin directly activates clotting factors and accelerates the formation of fibrin clots.

HEMOBLAST: Clinical Applications

HEMOBLAST can be used in various surgical specialties.
HEMOBLAST can be applied to focal bleeding areas, such as a peripheral vessel, or large diffuse bleeding fields like the mediastinum.
HEMOBLAST is suitable for use in high-risk patients prone to bleeding, such as those undergoing cardiac surgery revisions, LVAD patients, or patients on platelet inhibitors.
While promising, further research is needed to assess its effectiveness in clinical settings.

HEMOBLAST: Safety and Efficacy

This study showed no evidence of mediastinitis, sternal infections, allergic reactions, or 30-day mortality.
HEMOBLAST is an effective hemostatic agent in the treatment of surgical bleeding.
This study was conducted at a single institution with a small sample size, further research with larger cohorts is needed to validate the findings and confirm safety and efficacy.

HEMOBLAST: Limitations

This study was a single-center study, limiting generalizability.
Researchers have limited data on large-scale clinical impact, long-term effects, and cost-effectiveness.
This study had no control group, making it difficult to determine the efficacy of this treatment approach.
The effects of HEMOBLAST on different types of surgical bleeding (e.g., venous vs. arterial) are not yet established.

HEMOBLAST: Future Directions

The future of HEMOBLAST is promising, but additional research is needed.
Future studies should focus on larger-scale clinical trials to evaluate the long-term efficacy, safety, and cost-effectiveness of HEMOBLAST.
Future studies should explore the various clinical applications of HEMOBLAST in different specialties to optimize its use.
The development of HEMOBLAST could lead to improvements in surgical outcomes, reduced blood transfusions, and faster recovery time for patients.
