Uncontrolled bleeding from traumatic wounds is a major factor in deaths resulting from military conflict, accidents, disasters and crime. Self-assembling peptide nanofibers have shown superior hemostatic activity, and herein, we elucidate their mechanism by visualizing the formation of nanofiber-based clots that aggregate blood components with a similar morphology to fibrin-based clots. Further...

Considering that vaginal delivery is a painful process, the present study investigated the effects of Citrus aurantium on the severity of first-stage labor pain in primiparous women. This study was a randomized clinical trial conducted with 126 eligible primiparous patients. The pain severity of patients was measured at the time of enrolling in the study. In the intervention group, (aromatherap...

BACKGROUND Vapor-based fumigant systems for disinfection of health care surfaces and spaces is an evolving technology. A new system (AsepticSure) uses an ozone-based process to create a highly reactive oxidative vapor with broad and high-level antimicrobial properties. METHODS Ozone gas at 50-500 ppm was combined with 3% hydrogen peroxide vapor in a test chamber and upscaled in rooms measurin...

Using the physiology of moist wound healing as the framework, this nonexperimental, retrospective chart review compared the rate of wound healing and cost of wound care associated with wet-to-dry normal saline gauze dressings to the rate of wound healing and cost of wound care associated with amorphous hydrogel dressings for patients with infrainguinal arterial disease and diabetes. These patie...

Hemostat has been a crucial focus since human body is unable to control massive blood loss, and collagen proves to be an effective hemostat in previous studies. In this study, collagen was isolated from the mesoglea of jellyfish Rhopilema esculentum Kishinouye and its hemostatic property was studied. The yields of acid-soluble collagen (ASC) and pepsin-soluble (PSC) were 0.12% and 0.28% respect...

Dear Editor, Bleeding following tooth extraction is of concern to patients. Bleeding due to tooth extraction causes discomfort for patients. Proper control of bleeding is thus important. Postextraction oozing is common. However, bleeding usually stops after gauze is placed over the socket and compressed by biting down on the gauze for 30-60 min. In some patients oozing persists. A combination o...

Using a scintigraphic technique based on an autologous injection of 99mTc-labelled erythrocytes, we have evaluated the efficiency of different exsanguination procedures in the upper limb of ten healthy male volunteers. The methods were elevation alone, the use of the Esmarch bandage or a gauze bandage, the Pomidor roll-cuff, the squeeze method and the Urias bag. The various procedures gave the ...

OBJECTIVE To test the tensile properties of knotted suture made of 4 different suture materials and exposed to petroleum gauze. STUDY DESIGN We tested the tensile strength of United States Pharmacopeia size 0-0 gauge polydioxanone, polyglyconate, glycolide/lactide copolymer, and silk when exposed to petroleum packing or saline. Suture materials were randomized, and knots were tied and then ev...

This study evaluated the influence of tooth embedding media on the accuracy ofan electronic apex locator. The root canal length of 20 human mandibular canines was measured by inserting a 15 K-file into the root canal up to the apical foramen. The distance was measured with a digital caliper. The embedding media evaluated were alginate, saline, floral foam or gauze soaked in saline. Electronic r...
