Summary
Microfibrillar collagen hemostat (MCH) effectively stops venous bleeding in endoscopic endonasal transsphenoidal surgery (EETS). A new syringe injection method improves MCH delivery, making hemostasis easier, faster, and more precise.
Area of Science:
- Neurosurgery
- Surgical Innovation
- Biomaterials
Background:
- Microfibrillar collagen hemostat (MCH) is a recognized topical agent for venous hemostasis during endoscopic endonasal transsphenoidal surgery (EETS).
- Current handling of MCH can be challenging due to its tendency to adhere to surgical gloves and instruments, potentially complicating its application.
- Effective hemostasis is critical in EETS to minimize operative time and reduce complications.
Purpose of the Study:
- To introduce and evaluate a novel method for applying MCH suspension via a syringe applicator during EETS.
- To demonstrate that this injection technique facilitates easier, more precise, and rapid delivery of MCH to bleeding sites.
- To assess the efficacy and practicality of the MCH injection method for achieving venous hemostasis.
Main Methods:
- A suspension of MCH was prepared for delivery through a syringe applicator.
- The MCH suspension was administered directly to bleeding points during EETS using the syringe technique.
- The ease of preparation, handling, and precision of delivery were qualitatively assessed by the surgical team.
Main Results:
- The syringe applicator method allowed for rapid and precise delivery of MCH suspension to targeted bleeding areas.
- Effective venous hemostasis was achieved using the injection technique.
- The method proved to be easy to prepare, inexpensive, and addressed the handling challenges associated with conventional MCH application.
Conclusions:
- The syringe injection technique offers a practical and effective solution for applying microfibrillar collagen hemostat during EETS.
- This method enhances the precision and speed of MCH delivery, improving the efficiency of venous hemostasis.
- The described technique is a valuable, cost-effective adjunct for surgeons performing EETS, simplifying MCH application and ensuring effective bleeding control.
