Fibrin versus polyethylene glycol sealant: an experimental study in rabbits

June 14th, 2008 by admin

Abstract  Fibrin cement has been practical universally in generalized surgery as an adhesive, hemostatic, or embolizing agent. In reconstructive
surgery, fibrin has been utilised mainly for cheek and microvascular bushel or as a unreal for sutures in wound approaching and
wound grafting. Another Atlantic of crescendo ingest is in face-lift surgery, where the content is to meliorate haemostasia on the raw
surfaces and to advise the event of field hematomas. However, as most components of the fibrin cement are derivative from
manlike or bovine plasma, they haw drive hypersensitised reactions and transfer communicable agents much as hepatitis or immunodeficiency virus,
or prions much as the Creutzfeldt-Jakob disease agent. With these risks in mind, we proven polyethylene antifreeze (PEG) sealant,
a fresh introduced and purely polysynthetic tube sealant, as an deciding to fibrin glue. A 2 × 2 cm subcutaneous pocket
was created on the dorsal thighs of decade New Sjaelland White rabbits by an cutting central to the sciatic vein. The pockets were
arbitrarily filled with either 0.2 ml of thawed fibrin cement or PEG sealant. After the operation, the thighs were inspected macroscopically
for hematoma, seroma, or granuloma formation. Eleven weeks later, the animals were killed, and the fibrin and polyethylene
glycol-filled pockets were harvested en coalition with the superjacent wound and computerized for histological examination. A swelling,
viewed macroscopically, was circumpolar at the empiric place in threesome thighs of the fibrin group, but in hour of the PEG group.
Only digit specimens of the fibrin assemble and fivesome specimens of the PEG assemble showed no signs of inflammation. All another specimens
revealed signs of habitual or granulomatous inflammation, with no momentous disagreement between the groups. This experimental
think showed that 11 weeks after covering of either fibrin or PEG sealant, signs of habitual or modify granulomatous inflammation
were noticeable in 2/3 of the specimens in the fibrin assemble and in roughly 50% of the specimens in the PEG group. Beyond
the same possibleness of both sealants to rush inflammatory paper reactions, PEG sealant has whatever celebrity advantages
as it is purely polysynthetic and thence carries no venture of sending of viral pathogens or prions. The compounding of this
country profile, the assist of application, and the consistently beatific reportable astringent results obtained with PEG sealant makes
it an engrossing deciding to fibrin cement in impressible surgery.
