A low-cost and simple method to stop intraoperative leakage-type bleeding: use of the vancomycin-oxidized regenerated cellulose (ORC) sandwich.

Intraoperative bleeding may cause life-threatening complications in patients if such bleeding cannot be brought under control. Various materials are available for stopping such bleeding. However, there are some difficulties in the acquisition and application of these materials. The aim of this study was to investigate the efficiency of the low-cost and simple-to-prepare vancomycin-oxidized regenerated cellulose (ORC) sandwich in surgical bleeding control. Thirty New Zealand rabbits were used for this purpose. The animals were separated into three groups as group 1 (n = 10), control group; group 2 (n = 10), oxidized regenerated cellulose (ORC) group; and group 3 (n = 10), vancomycin-ORC sandwich group. Left thoracotomies were performed on the rabbits under general anesthesia, and bleeding was created in the parietal pleura. The amount of bleeding in the groups was measured and compared. The amount of bleeding in the group in which the vancomycin-ORC sandwich was used was found to be less, compared to the other two groups. According to these results, we conclude that the vancomycin-ORC sandwich can be used safely in the control of intraoperative leakage-type bleeding, as the vancomycin-ORC sandwich is a low-cost, easily applied, and easily acquired material.
