ABSTRACT

BACKGROUND: Many topical hemostatics are widely applied for bleeding control. They can be classified into two categories according to their mechanism of action on the clotting cascade in a biologically active or passive manner. Passive hemostatics include cellulose and gelatin. We performed an experimental study to compare the effect of passive hemostatics in wound healing by applying them to a rectus abdominis muscle defect of white mice. METHODS: Surgicel is a sterile absorbable knitted fabric prepared by the controlled oxidation of regenerated cellulose. Spongostan is an absorbable hemostatic gelatin sponge. In 30 mice, a 1x1 cm defect was created on the rectus abdominis muscle and the materials were applied in three ways: control group, cellulose (Surgicel) group, gelatin (Spongostan) group. For the histologic analysis, biopsies were performed at 3 and 28 days. RESULTS: After 3 days, the cellulose group showed limited granulation formation with acute inflammatory reactions similar to the control group. At the 28th day, moderate amounts of granulation tissue formation was observed with milder inflammatory reactions than the control group. In the gelatin group, after 3 days, gelatin remnants were observed surrounded by severe inflammatory changes. After 28 days, the same quantity of gelatin remnants could be still observed. CONCLUSIONS: This study suggests that cellulose is associated with minimal morbidity in wound healing, while the use of gelatin shows severe adverse tissue reactions with delayed wound healing. Consequently, cellulose is better than gelatin when considering wound healing.

ABSTRACT

Objetivo: Verificar por meio de análise histológica os efeitos de agentes hemostáticos na reparação óssea, colocados em defeitos ósseos nas tíbias direita e esquerda de ratos jovens. Métodos: Foram utilizados 32 ratos machos (Holtzman). Após assepsia e anestesia, foi realizada incisão de 1cm em cada perna, expondo a região anterior da tíbia. Utilizando um micromotor e broca esférica, foram preparadas cavidades, expondo a medula óssea, as quais foram irrigadas com ácido épsilon-aminocapróico (EACA) ou preenchidas com gelatina absorvível Gelfoam. Nos períodos de sete, 14, 30, 45 dias, os animais foram sacrificados segundo o protocolo bioético, as tíbias removidas e fixadas em formol a 10% para inclusão em parafina e análise em microscopia de luz. Resultados: A análise dos cortes histológicos demonstrou que em todos os grupos (controle e tratados) os fenômenos biológicos da reparação óssea estiveram presentes, com diferença apenas na cronologia. As reações da reparação óssea confirmaram a biocompatibilidade dos materiais; o grupo tratado com Gelfoam apresentou discreta aceleração no processo de reparação tecidual em relação aos demais grupos, principalmente nos períodos de 14, 30 e 45 dias pós-cirurgia. O Gelfoam foi totalmente reabsorvido; a remoção dos agentes hemostáticos das lojas cirúrgicas acelera o processo de reparação tecidual. Conclusão: Em todos os grupos experimentais, a seqüência de fenômenos biológicos que compõem a reparação óssea esteve presente, havendo diferença na cronologia. As reações apresentadas no reparo ósseo confirmaram a biocompatibilidade dos materiais. A remoção total dos agentes hemostáticos nas lojas cirúrgicas acelera o processo de reparação tecidual...

ABSTRACT

We report the computed tomographic and angiographic findings in the case of a recently obtained successful clinical outcome after embolization of the hepatic artery in the case of a snakebite causing hemoperitoneum associated with hepatic necrosis and rupture with active bleeding.

ABSTRACT

The purpose of this study to compare the use of Autogenous Fibrin Glue [A.F.G.] with the use of Gelfoam in myringoplasty.50 patients with dry central perforations were selected from ENT outpatient clinic in El-Minia University Hospital. In 25 patients we used the prepared autogenous fibrin glue [A.F.G.] in myringoplasty while the gelfoam balls were used in the another 25 cases. The results of autogenous fibrin glue [A.F.G.] group were better than the results of gelfoam group. We concluded that the results of this study recommend the use of autogenous fibrin glue [A.F.G.] in myringoplasty as it improves grafts take, does not transmit any infectious diseases and does not impose any change in technique

ABSTRACT

Os autores estudaram histologicamente o implante de esponja de fibrina ("Fibrinol") em alvéolos dentais de ratos. Dois grupos de 30 animais foram utilizados, sendo seus incisivos superiores direitos extraídos e a esponja de fibrina implantada nos alvéolos dos animais de um dos grupos. Seis animais foram sacrificados aos 3, 6, 9, 15 e 21 dias pós-operatórios, e as peças obtidas coradas por hematoxilina e eosina para estudo histológico. Os resultados obtidos permitiram concluir que: 1) a esponja de fibrina mostrou-se clinicamente eficiente nas hemorragias intra-alveolares; 2) o material é gradualmente absorvido ao longo da reparação alveolar, cedendo lugar ao coágulo sangüíneo; 3) o implante de esponja de fibrina em alvéolos dentais de ratos provocou retardo no processo de reparo
