Utility of Microporous Polysaccharide Hemospheres in Severe Hepatic Trauma: Experimental Study of Hemostatic Strength and Ease of Use.

Published:November 19, 2022DOI:



      Animal studies confirm the utility of hemostatics against standard packing following severe liver injury. We investigated the efficacy and ease of use of novel microporous polysaccharide hemosphere (MPH) compounds (Perclot®, Baxter) in the treatment of severe hepatic hemorrhage in pig.


      Pigs were randomized to one of two equal treatment groups: MPH compounds (n=12) and Standard Packing (n=12). All animals underwent standardized surgical devascularization of the suprahepatic veins (grade V) to induce severe hepatic injury. Measures relating to the hemostatic success were monitored at 12, 60, 120 minutes and 24 hours post injury.


      Animals allocated to treatment with MPH compounds were associated with higher survival rates at 24 hours than those undergoing standard packing: 66.7% vs, 0%, respectively (p=0.001). At 120 minutes MPH compounds were also associated with reduced blood loss, median (IQR) 1.16 (0.60) vs. 10.19 (5.77) mL/Kg, respectively: p<0.001) as well as higher invasive mean arterial pressures (iMAP) median (IQR) 39.12 (11.29) vs. 25.75 (14.28) mmHg, respectively: p=0.14) and hemoglobin levels median (IQR) 5.45 (2.50) vs. 6.45 (1.73) g/dL, respectively p=0.127). Overall, the application of MPH compounds required nearly half the time of standard packing median (IQR) 32.92 (6.51) vs. 67.75 (14.66) sec, respectively: p<0.001).


      The data suggests that the use of MPH works in a severe hemorrhage in the liver of pigs, improving many variables in comparison to standard packing, including survival, blood loss and speed of application and we conclude that this offers a potential alternative for the treatment of hepatic injury. Further work is needed to corroborate these findings.
