A quicker preparation method for autologous fibrin glue

Area of Science:

• Biochemistry
• Hematology
• Medical Technology

Background:

• Cryoprecipitate (Cryo) is utilized as fibrin glue in surgical applications.
• Current preparation methods for autologous Cryo can be time-consuming.
• Enhancing the yield of coagulation factors in Cryo is crucial for its efficacy.

Purpose of the Study:

• To develop a faster method for preparing autologous cryoprecipitate.
• To investigate the impact of different preparation conditions on coagulation factor concentrations and yields in Cryo.
• To optimize Cryo preparation for use as fibrin glue.

Main Methods:

• Human plasma from healthy volunteers was subjected to various freezing, shaking, and thawing conditions.
• Cryoprecipitate was isolated from treated plasma samples.
• Concentrations of fibrinogen, plasminogen, fibronectin, and factor XIII in Cryo were quantified.

Main Results:

• Cryoprecipitate derived from plasma stored at -20°C exhibited significantly higher concentrations and yields of plasma components compared to plasma stored at -80°C.
• Incorporating shaking at 70 cycles/min during the freezing process positively influenced coagulation factor concentrations and yields.
• A shaking thaw process in a cold water bath proved to be an efficient method for achieving adequate coagulation factor yields.
• Shaking during the defrosting phase did not significantly alter coagulation factor yields.

Conclusions:

• High-concentration cryoprecipitate can be rapidly prepared from autologous plasma within 4-5 hours.
• Optimized freezing and thawing protocols enhance the yield of essential coagulation factors.
• This streamlined preparation procedure facilitates the efficient production of cryoprecipitate for fibrin glue applications.
