BACKGROUND/AIM: The protective effects of prostaglandin (PG) analogs on ischemia-reperfusion (I/R) have been well documented; however, comparative studies are lacking. The aim of the present study was to determine whether iloprost or alprostadil is more effective in preventing muscle I/R injury. MATERIALS AND METHODS: Thirty-two rats were divided into four groups (n = 8): sham, control, IL (I/R + iloprost), and AL (I/R + alprostadil). I/R was induced by a tourniquet in the hindlimb for 3 h/3 h...

REVIEW
John F Kragh, Michael A Dubick
The purpose of this review is to summarize tourniquet science for possible translation to wilderness settings. Much combat casualty data has been studied since 2005, and use of tourniquets in the military has changed from a last resort to first aid. The US Government has made use of tourniquets a health policy aimed to improve public access to bleeding control items. International authorities believe that education in first aid should be universal, as all can and should learn first aid. The safety record of tourniquet use is mixed, but users are reliably safe if trained well...

REVIEW
Ronald Chang, Brian J Eastridge, John B Holcomb
Hemorrhage is the leading cause of preventable military and civilian trauma death. Damage control resuscitation with concomitant mechanical hemorrhage control has become the preferred in-hospital treatment of hemorrhagic shock. In particular, plasma-based resuscitation with decreased volumes of crystalloids and artificial colloids as part of damage control resuscitation has improved outcomes in the military and civilian sectors. However, translation of these principles and techniques to the prehospital, remote, and austere environments, known as remote damage control resuscitation, is challenging given the resource limitations in these settings...

BACKGROUND: Twenty years ago, the original Tactical Combat Casualty Care (TCCC) article was published in this journal. Since TCCC is essentially a set of bestpractice prehospital trauma care guidelines customized for use on the battlefield, the presence of a journal with a specific focus on military medicine was a profound benefit to the initial presentation of TCCC to the US Military. METHODS: In the two ensuing decades, which included the longest continuous period of armed conflict in our nation's history, TCCC steadily evolved as the prehospital trauma care evidence base was augmented and as feedback from user medics, corpsmen, and pararescuemen was obtained...

INTRODUCTION: While studies using various materials to overcome ischemia-reperfusion (IR) injury are becoming increasingly common, studies on the effects of botulinum toxin A (BoTA) on IR injury in musculocutaneous flaps are still limited. The purpose of this study was to examine our hypotheses that BoTA provide protection of musculocutaneous flap from ischemia-reperfusion injury. METHOD: Five days after pretreatment injection (BoTA versus normal saline), a right superior musculocutaneous flap (6 × 1...

OBJECTIVE: Vascular calcifications on the preoperative radiograph of patients scheduled for total knee arthroplasty (TKA) often give rise to concern, as their clinical relevance remains uncertain. The aim of this study was to investigate whether these vascular calcifications-especially medial artery calcifications (MACs), which increase arterial stiffness-were associated with tourniquet failure and thus with increased intraoperative blood loss. MATERIALS AND METHODS: A total of 765 patients who underwent primary TKA with a tourniquet (cuff pressure 350 mmHg) between 2009 and 2011 were screened for vascular calcifications on the preoperative radiograph...

OBJECTIVE: Arteriovenous fistulas and grafts may often be associated with localized complications related to aneurysms/pseudoaneurysms, buttonholes, or structural defects that require proper management to ensure continued access functionality for hemodialysis. Partial aneurysmectomy and repair (PAR) is a targeted surgical approach specifically designed for managing these complications. The basic concepts of PAR include resecting unhealthy or excessive tissue over an access, reconstructing the vascular access lumen using in situ vascular wall or tissue when possible, and closing overlying skin with healthy margins to promote reliable healing...

Our aim was to examine the effects of ischemic preconditioning (IPC) on the local periosteal and systemic inflammatory consequences of hindlimb ischemia-reperfusion (IR) in Sprague-Dawley rats with chronic estrogen deficiency (13 weeks after ovariectomy, OVX) in the presence and absence of chronic 17beta-estradiol supplementation (E2, 20 µg kg(-1) , 5 days/week for 5 weeks); sham-operated (non-OVX) animals served as controls. As assessed by intravital fluorescence microscopy, rolling and the firm adhesion of polymorphonuclear neutrophil leukocytes (PMNs) gave similar results in the Sham + IR and OVX + IR groups in the tibial periosteal microcirculation during the 3-h reperfusion period after a 60-min tourniquet ischemia...

Acute lower extremity ischemia is a limb-and life-threatening problem. The timing of clinical intervention is critical to achieving optimal outcomes. However, there has been a lack of effective techniques capable of evaluating muscle and limb damage. Microcirculatory injury is the initial pathological change during ischemic muscle injury. Here, we performed photoacoustic imaging (PAI) in real time to quantitatively detect the degree of microcirculatory injury of ischemic muscles in a rat model in which Evans blue (EB), which strongly binds to albumin in blood, was used as a nontoxic molecular PA probe...

BACKGROUND: Torso hemorrhage constitutes a leading cause of battlefield mortality. The Abdominal Aortic and Junctional Tourniquet (AAJT) uses a pneumatic bladder to compress the aorta reducing pelvic and lower extremity perfusion; however, concern exists over the risk of caval compression exacerbating hypotension after application. METHODS: Male swine (70-90 kg) were randomized into four groups of 10: presence or absence of hemorrhage and AAJT placement. After a 40% hemorrhage, a 15-min period of hypovolemia was observed before the AAJT application...

The regulation of skin blood flow (SBF) is primarily mediated by the sympathetic nervous system, but the effects of electrical stimulation (ES) of one limb on SBF in the other limbs remain unknown. The present study investigated the effects of unilateral forelimb ES on SBF in the bilateral hindlimbs in anesthetized rats. Bilateral hindlimb ischemia was induced by tourniquet application for 60min. After reperfusion for 24h, ES (3 or 125Hz) was applied to the upper one-fourth of the triceps brachii muscle of the left or right forelimb for 30min...

In the absence of a specific laboratory test of envenomation, there is a need for an alternative mechanism for the early recognition of envenomation following hematotoxic snake-bite in tropical countries. Abnormalities of clotting are commonly associated with hematotoxic snake bite either due to systemic envenomation or due to the release of an inappropriate tourniquet applied as 'first-aid' often by the rural people before presentation to the hospital. Thromboelastography (TEG) has been used to monitor the coagulation abnormalities in various clinical scenarios...

Traumatic hemorrhage has been identified as the leading cause of battlefield death in recent conflicts. Although injury patterns are not directly reproducible to the civilian world, treatment advancements can be used to provide care to patients worldwide. Long-standing dogma regarding the use of tourniquets has been disproved, and there is now recognition of the critical role that tourniquets play in trauma care. The history and evolution of tourniquets, including the identification of previous faults in application, will lead to an examination of the current devices in use along with evidence-based recommendations for use...

BACKGROUND: Surgical flaps have become reliable tools in the microsurgical armamentarium, but are still faced with tissue loss due to impaired perfusion which can lead to complete flap failure. Remote Ischemic Conditioning (RIC) has been demonstrated to be an effective way to improve microcirculation in surgical flaps in humans. However, little is known about the optimal amount and length of RIC cycles. OBJECTIVE: Determination of a superior protocol for RIC of cutaneous microcirculation in humans...

BACKGROUND: A physiological oxygen transport through a circulatory and microcirculatory system is essential for execution of cellular functions. Several pathological conditions e.g. infections, ischemia, cancer, diabetes, hypertension or chronic wounds show a change of oxygen distribution and oxygen tension in cellular microenvironment. Additionally complex operative procedures in order to reconstruct tissue defects require a reliable monitoring of microcirculation. OBJECTIVE: Target of this study was to evaluate skin oxygenation during an ischemia-reperfusion experiment using transepidermal oxygen flux imaging...

Placenta previa accreta (PPA) can result in severe obstetric hemorrhage, which usually necessitates hysterectomy. The median blood loss for placenta accreta has been reported to range from 2000 to 7800 mL [1]. It is a severe and life-threatening obstetric complication in most countries. The present article reports a conservative, simple method-the two-tourniquet sequential blocking technique-to control severe bleeding during cesarean delivery in the event of PPA.
