Preparation and evaluation of porous starch / chitosan composite cross-linking hemostatic
Publication date: Available online 25 May 2019Source: European Polymer JournalAuthor(s): YanChen, JunQing Qian, ChangYan Zhao, LieChao Yang, Jing Ding, Hui GuoAbstractComposite porous starch (PS) with chitosan (CS) was easily cross-linked by sodium trimetaphosphate (STMP) to obtain a hemostat called STMP/PS/CS(SPC) with ideal hemostatic effect. The water absorption ratio and swelling ratio of SPC reach up to 150.8%, 355.0% respectively and it was observed by scanning electron microscopy (SEM) that a large amount of CS was combined with PS, which indicated the composite effect was ideal. Synergistic hemostatic effect of SPC...

N-Alkylated Chitosan/Graphene Oxide Porous Sponge for Rapid and Effective Hemostasis in Emergency Situations
Publication date: Available online 9 May 2019Source: Carbohydrate PolymersAuthor(s): Ying Zhang, Jing Guan, Jimin Wu, Sheng Ding, Jian Yang, Jianhua Zhang, Anjie Dong, Liandong DengAbstractN-alkylated chitosan (AC) sponges and graphene oxide (GO) sponges are promising candidates for emergency hemostat. However, AC sponges have weak mechanical strength and GO sponges may induce toxicity. To overcome these problems, a series of AC/GO composite spongs (ACGS) were prepared with various ratios (GO/AC, 0%, 5%, 10%, and 20%) using a dilute solution freeze phase separation and drying process. The sponges exhibit excellent absorpti...

Innovative use of a bangle as a hemostat during hair transplantation
During the procedure of hair transplantation, it is common practice to make slits at the recipient area before the implantation of extracted hair follicle units. This process is commonly associated with heavy bleeding, which obscures the operative field. This not only increases the procedure time but also makes it difficult to create uniform slits. Using tumescence is a solution to decrease the bleeding, but the efficacy of this is limited. We suggest the use of a readily available steel bangle or bracelet while making slits to decrease operative site bleeding (Fig 1).

Lymphostasis and Hemostasis in Body-Contouring Surgery Using a Polysaccharide Based Hemostat (4DryField PH)
Conclusions:
This is the first prospective, monocentric, randomized study on 4DF in body-contouring surgery. The use of 4DF did not lead to a better postoperative outcome regarding hemostasis and lymphostasis. Potential benefits need further evaluation in high-volume studies.

Effects of Ankaferd Hemostat on Helicobacter pylori strains and antibiotic resistance
Conclusion: Our present study indicated, for the first time, that ABS could act against H. pylori. ABS is clinically used for the management of GI bleeding due to benign and malignant GI lesions. Thus, the possible anti-H. pylori effect of ABS shall expand the therapeutic spectrum of the drug in GI lesions in relation to H. pylori infection such as peptic ulser disease (PUD) and lymphoid tissue (MALT) lymphomagenesis.

Effects of Ankaferd Hemostat on red blood cell aggregation: a hemorheological study
Conclusion: ABS has antierythroid aggregation effect. ABS inhibits pathological aggregation of red blood cells. Antithrombotic clinical effects of ABS may be ascribed to the antierythroid aggregan actions of the drug.

A modified endovascular treatment protocol for iatrogenic internal carotid artery injuries following endoscopic endonasal surgery.
CONCLUSIONSThe endovascular treatment protocol used in this study for ICA injuries during EES was helpful in the management of this rare complication. Willis stent placement improved the preservation rate of injured ICA during EES. It would be highly advantageous to manage this complication in a hybrid OR or by a mobile C-arm to get a clear intraoperative angiogram.

Enhancement of Hemostatic Property of Plant Derived Oxidized Nanocellulose-Silk Fibroin Based Scaffolds by Thrombin Loading
Publication date: Available online 19 December 2018Source: Carbohydrate PolymersAuthor(s): Anha Afrin Shefa, Mirana Taz, Sun Young Lee, Byong-Taek LeeAbstractTo combat post-surgical and traumatic bleeding conditions effective hemostasis is of great importance. The study was designed to investigate the effect of thrombin (Th) loading on hemostatic performance of TEMPO-oxidized cellulose nanofiber (TOCN)-silk fibroin (SF) scaffolds. Addition of SF with TOCN significantly (***P < 0.001) increased blood absorption capacity and improved biocompatibility of TOCN. Thrombin loading potentiated platelet activation and hemostati...

Investigation of efficiency of a novel, zinc oxide loaded TEMPO-oxidized cellulose nanofiber based hemostat for topical bleeding.
Abstract
Lethal bleeding due to street accidents, natural calamities, orthopedic/dental surgeries, organ transplantation and household injuries, is the leading cause of morbidity and mortality. In the current study, zinc oxide (ZnO) was incorporated in TEMPO-oxidized cellulose nanofiber (TOCN) and polyethylene glycol (PEG) polymer system for hemorrhage control by freeze drying method. SEM and XRD data showed the presence of ZnO in the porous structure. FT-IR analysis showed that, successful conjugation occurs among the TOCN and PEG. The results revealed that, the incorporation of ZnO and higher concentrations of P...
