background despite several studies investigating the pathophysiologic effects of tourniquet usage in extremity surgeries, there are not enough data about these effects in adhesion release surgeries of burn patients. in the light of numerous metabolic changes of burn tissues, we tried to determine whether there are any significant differences in metabolic responses of burn tissues to tourniquet ...

This paper describes the simulation of movement control of a one-degree-of-freedom articulated robot arm SCARA actuated by a pair of McKibben pneumatic artificial muscles. The pneumatic artificial muscle is the actuator and emulates the behavior of biological muscles; due to its nonlinear behavior, there is also a need to develop control systems for robot arms using this type of actuator. Resea...

In Japanese society, an important problem of providing nursing care for the elderly has occurred. As a result, it is necessary to develop systems to aid in nursing care. The actuators required for such a system need to be flexible so as not to injure the body. The purpose of our study is to develop a flexible and lightweight actuator which can be safe enough to be attached to the human body. We...

The modeling of pneumatic actuators, also known as artificial muscles, has been the main focus in several research papers in the past [1, 2, 3, 4, 5]. At the Center for Intelligent Systems (CIS) at Vanderbilt University, we have been using pneumatic actuators for our Intelligent Soft Arm Control (ISAC, Figure 1). For the position control of a joint, driven by two artificial muscles, a physical ...

We present a case of emergency tourniquet use of unusually long duration. The patient was wounded during combat operations, and the subsequent battle and evacuation caused a significant delay in surgical treatment of his wounds. Emergency tourniquets can be lifesaving, but are not benign interventions. In general, the extent of tourniquet injury increases with increasing time of application. De...

The 232 patients had 428 tourniquets applied on 309 injured limbs. The most effective tourniquets were the Emergency Medical Tourniquet (92%) and the Combat Application Tourniquet (79%). Four patients (1.7%) sustained transient nerve palsy at the level of the tourniquet, whereas six had palsies at the wound level. No association was seen between tourniquet time and morbidity. There was no appar...

Bleeding prevention and control by tourniquet use by out-of-hospital caregivers is a major breakthrough in military medicine of current wars. The present review documents developments in tourniquet practices since 2001 among the US military services for aid in improving doctrine, policy, and especially care in wars to come. Tourniquets are an adjunct for resuscitation in self-care and buddy aid...

BACKGROUND Previously we showed that tourniquets were lifesaving devices in the current war. Few studies, however, describe their actual morbidity in combat casualties. The purpose of this study was to measure tourniquet use and complications. METHODS A prospective survey of casualties who required tourniquets was performed at a combat support hospital in Baghdad during 7 months in 2006. Pati...
