Context:In today’s modern world, despite the multiple advances made in the field of medicine, hemorrhagic shock is still the main cause of battlefield mortality and the second most prevalent cause of mortality in civilian trauma. Hemostatic agents can play a key role in establishing hemostasis in prehospital situations and preventing hemorrhage-associated death. In this respect, this article aims to review different aspects of known hemostatic agents.Evidence Acquisition:A comprehensive search of the academic scientific databases for relevant keywords was conducted; relevant articles were compiled and assessed.Results:Hemostatic agents can establish hemostasis by means of different mechanisms, including concentrating coagulation factors, adhesion to the tissues, in which traumatic hemorrhage occurred, and delivering procoagulant factors to the hemorrhage site. Presently, these hemostatics have been significantly improved with regard to efficacy and in adverse consequences, resulting from their use. Several hemostatic dressings have been developed to the degree that they have received FDA approval and are being used practically on the battlefield. In addition, there are currently several case reports on the use of such hemostatics in the hospital setting, in conditions where commonly known approaches fail to stop life-threatening bleeding.Conclusions:The use of hemostatic dressings and agents is one of the main advancements achieved in recent decades. However, it can be claimed that the ideal hemostatic has not been recognized yet; therefore, this topic needs to be brought into focus and further addressed.

BackgroundInguinal hernia is one of the most common male diseases all over the world with an incidence rate of 18-24% throughout life. Chronic inguinal pain is one of the complications that prolong return to work time.ObjectivesThe main aim of this study was to determine the effect of ilioinguinal neurectomy on postoperative chronic pain (PCP) in patients that underwent open inguinal hernia repair via the Lichtenstein method.Materials and MethodsIn this randomised controlled clinical trial, male patients with unilateral inguinal hernia were randomized into two groups: 74 cases in the preserved-nerve group and 66 cases in the nerve-excised group. The method of herniorrhaphy was the classic Lichtenstein method. Pain and numbness were evaluated at 1 day, 1 week, 1 month, 6 months and 1 year after surgery via visual analogue scale (VAS) system. We used SPSS ver.16 for analysis.ResultsAll patients were male with mean age of 39.1 years (with a range of 18 to 68 years). The follow-up rate was 100% after 1 year. Pain severity was significantly lower in nerve-excised patients at 1 day, 1week, 1 month and 6 months after surgery; but it was not significant after one year, although overall pain severity was low. Numbness was significantly higher in excised patients at all endpoints (1 day, 1month, 3 months, 6 months and one year after surgery).ConclusionsIlioinguinal nerve excision at the time of inguinal hernia repair decreased post-surgical inguinal pain, and it can be used as a routine method in herniorrhaphy.

Administrated normal saline individually reduce the adhesion grade near cecum. Conversely, usage of methylene blue 1% may unpredictably increase risk of adhesion formation.

Administration of chitosan-gelatin films with higher than 25% weight of chitosan had no effect on reduction of adhesion formation in the rat cecum model.

Introduction: Planning for management of bleeding in trauma injuries is very important. The initial purpose in emergency situations should be immediate establishment of an efficient hemostasis, principally in its topical application. In this study, we aimed to review the major relevant articles in the case of application of cellulose hemostatic agent on trauma injuries. Methods: We searched the online databases such as PubMed, MEDLINE, Wiley, EMBASE, ISI Web of Knowledge, and Scopus. Two reviewers independently searched and assessed the titles and abstracts of all articles. Results: Upon screening the titles and abstracts, 24 studies were identified for full-text review. The oxidized cellulose had the best clotting times, while it demonstrated low absorption ability. Surgical and thermosensitive chitosan hemostatic could be valuable for managing hemorrhage from liver injuries in trauma patients. Conclusion: Recently, the application of cellulose hemostatic agents has been one of the main improvements obtained for controlling bleeding in trauma injuries. However, generally according to the literature review, the decision about using each agent should be made on a case-by-case basis. However, it can be mentioned that the perfect hemostatic agent has not been still identified.
