AI Article Synopsis
- The bilayer gelatin sealing sheet is a low-cost and effective hemostatic agent developed for surgical use.
- In a study using dogs, both the gelatin and fibrin glue sealing sheets successfully stopped bleeding from femoral arteries, but the gelatin sheet showed superior results in reducing postoperative adhesions and inflammation.
- The findings suggest that gelatin sealing sheets can serve as an effective alternative to fibrin glue in surgical procedures.
Article Abstract
Background: The bilayer gelatin sealing sheet was developed as a safe, effective, easy-to-handle and low-cost hemostatic agent.
Objective: To examine the feasibility of gelatin sealing sheets using a canine arterial hemorrhage model.
Methods: In vivo degradation of gelatin sealing sheets was examined by implanting subcutaneously in rats. For the hemostatic and anti-adhesion efficacy investigations, femoral arteries of dogs were pricked with syringe needle to make a small hole and a gelatin (i.e. experimental group) or fibrin glue sealing sheet (i.e. control group) was applied on the hole to stop bleeding (n=8). After discontinuation of the bleeding, the skin incisions were closed and re-examined 4 weeks postoperatively.
Results: From the degradation study, 4 h thermally treated gelatin sheet which degraded within 3 weeks in vivo was chosen for the further hemostatic study. In all cases of gelatin and fibrin glue sealing sheets, bleeding from the needle hole on canine femoral arteries was effectively stopped. Postoperative adhesions and inflammation at the site in the experimental group were significantly less than those in the control group (P<0.01 for adhesion scores).
Conclusions: The gelatin sealing sheet was found to be as effective as the fibrin glue sealing sheet as a surgical hemostatic agent, and more effective in preventing postoperative adhesions.

Tissue adhesives have attracted significant interest in the field of hemostasis. However, challenges including weak tissue adhesion, inadequate biocompatibility, and instability limit their clinical applications. Here, we have developed a gelatin-DOPA-knob/fibrinogen hydrogel inspired by the fibrin polymerization and mussel adhesion, resulting in a biocompatible bioadhesive with outstanding adhesion performance and great storage stability.

This systematic review assessed the comparative effectiveness of surgical drainage techniques and postoperative interventions in reducing complications across various surgical fields. We conducted a comprehensive search across multiple databases, including PubMed, MEDLINE, Embase, the Cochrane Library, and CINAHL, covering studies from January 2019 to September 2024. Ten randomized controlled trials met our inclusion criteria, focusing on human surgical patients and comparing outcomes such as seroma, hematoma, infection rates, and postoperative pain.

With increasing clinical demands for painless and easy administration of medications, such as for hair loss, microneedles (MNs) have been widely exploited for facilitating drug permeation in a minimally invasive manner. However, precise dose control and long-term drug delivery without the infection risk through punctured holes have remained unresolved. Herein, we developed swellable microneedles (MNs) with an air-pocket structure, enabling shear-induced implantation inside the skin.

Context: Mineral Trioxide Aggregate (MTA) is a calcium silicate-based cement that potentially exhibits improved washout resistance when carboxymethyl chitosan or gelatin is incorporated. Gel-form MTA is a novel mineral trioxide aggregate formulated using construction industry-based technology. The present study was conducted to comparatively evaluate the sealing ability and adaptation to dentinal walls of gel-form MTA.
