Brad L Bennett, John B Holcomb
For centuries, cold and wet weather has affected military combat operations leading to tremendous loss of manpower caused by cold-weather-related injuries including trench foot, frostbite, and hypothermia. The initial battlefield management of hypothermia in military personnel had not advanced significantly following many wars and conflicts until 2006. The aim of this review is to: 1) provide an overview of trauma-induced hypothermia (TIH); 2) highlight the Department of Defense strategy for the implementation of a hypothermia clinical management program for battlefield (prehospital) casualties; 3) highlight the research and development of the Hypothermia Prevention and Management Kit (HPMK) as the preferred field rewarming system for battlefield TIH; and 4) emphasize how the HPMK can be easily transitioned to the civilian sector for active rewarming of both accidental and TIH patients...

Deep frostbite is a thermal injury associated with significant morbidity. Historically, this has been associated with military personnel; however, increasingly it is becoming an injury that afflicts the civilian population. The use of intravenous iloprost or intra-arterial thrombolytics has led to promising tissue salvage. This article provides an up-to-date understanding of frostbite pathophysiology, classification, prevention, and management. It also highlights the role of telemedicine in optimizing patient outcomes...

This case study describes frostbite, a previously unreported complication following cryolipolysis, which resulted in substantial necrosis of the flank. Medical attention was not sought until one week after treatment. On examination, two distinct areas of significant frostbite in the left flank with surrounding erythema were revealed. Surgical intervention was avoided, as is recommended in cases of frostbite, and conservative treatment resulted in recovery of the affected area. Here, the authors highlight the adverse effects related to cryolipolysis, analysing the pathogenesis, clinical manifestations and management of this injury...

Frostbite is a localized cold thermal injury that results from tissue freezing. Frostbite injuries can have a substantial effect on long-term limb function and mobility if not promptly evaluated and treated. Imaging plays a critical role in initial evaluation of frostbite injuries and in monitoring response to treatment. A multimodality approach involving radiography, digital subtraction angiography (DSA), and/or multiphase bone scintigraphy with hybrid single photon emission computed tomography (SPECT)/computed tomography (CT) is often necessary for optimal guidance of frostbite care...

PURPOSE: To evaluate intraarterial catheter-directed thrombolysis for prediction and prevention of delayed surgical amputation as part of multidisciplinary management of frostbite injury. MATERIALS AND METHODS: A retrospective review was performed of 13 patients (11 men, 2 women; median age, 33.4 y; range, 8-62 y) at risk of tissue loss secondary to frostbite injury and treated with catheter-directed tissue plasminogen activator (t-PA) thrombolysis. Amputation data were assessed on follow-up (mean, 23 mo; range, 9-83 mo)...

Frostbite remains a challenging clinical scenario with multiple treatment algorithms and variable results. Currently, frostbite management often follows a conservative approach with rewarming followed by wound care and delayed amputation. We review seven patients where single-photon emission computed tomography (SPECT) fused with conventional computed tomography was used to evaluate tissue viability for earlier directed debridement and limb salvage. The goal of this report is to evaluate SPECT/CT as an appropriate modality for the screening of necrotic bone for earlier amputation in patients with frostbite...

An approximately 5-year-old female grey-headed parrot (Poicephalus fuscicollis suahelicus) was evaluated after exposure to outdoor temperatures below -20°C (-4°F) for approximately 22 hours. Severe frostbite affecting multiple digits, as well as dehydration and a depressed attitude, were diagnosed. Treatment included oral antibiotics, antifungals, nonsteroidal anti-inflammatories (NSAIDs), pentoxifylline, and topical aloe vera. Surgical amputation of the affected toes was not performed. Mild to moderate pododermatitis over the intertarsal joints developed because of a shift in weight bearing after the loss of most digits...

Despite advances in outdoor clothing and medical management of frostbite, individuals still experience catastrophic amputations. This is a particular risk for those in austere environments, due to resource limitations and delayed definitive treatment. The emerging best therapies for severe frostbite are thrombolytics and iloprost. However, they must be started within 24 hours after rewarming for recombinant tissue plasminogen activator (rt-PA) and within 48 hours for iloprost. Evacuation of individuals experiencing frostbite from remote environments within 24 to 48 hours is often impossible...

INTRODUCTION: The debilitating impact of cold weather on the human body is one of the world's oldest recorded injuries. The severe and life-changing damage which can be caused is now more commonly seen recreationally in extreme outdoor sports rather than in occupational settings such as the military. The diagnosis and treatment of these injuries need to be completed carefully but quickly to reduce the risk of loss of limb and possibly life. Therefore, we have conducted a systematic review of the literature surrounding cold weather injuries (CWIs) to ascertain the epidemiology and current management strategies...

BACKGROUND: Numerous studies have found appraisals of pain as a source of potential threat or tissue damage influence pain perception and coping. Conversely, causal effects of challenge appraisals reflecting potential future benefits of bearing pain have received little attention. This experiment was designed to elucidate effects of appraising laboratory pain as a source of potential threat and challenge on pain perception and coping. METHODS: Before engaging in a cold pressor test (CPT), young adult women (N = 112) and men (N = 49) were randomly assigned to one of three conditions: a higher threat group in which participants read an orienting passage describing symptoms and consequences of frostbite (pain as a signal for nociception), a lower threat group in which participants read about CPT safety (pain independent of nociception) or a challenge appraisal group in which participants read a passage describing how persistence in the face of discomfort predicts future life success and satisfaction...

For those at risk for cold-related injury, frostbite contributes significant morbidity through loss of limbs and digits. Frostbite injury generally affects distal extremities first and spreads proximally as the time of exposure increases. The Hennepin score is a tool to quantify injury and tissue loss of frostbite injury, similar to TBSA calculators in burn patients. Application of the Hennepin score allows for a clear picture of the effect of treatment through calculation of a salvage rate. The authors found high reliability between raters using the Hennepin score worksheet, suggesting consistency with applying the score to frostbite injury and outcomes (intraclass correlation, 0...

Frostbite injury in children can lead to abnormal growth and premature fusion of the epiphyseal cartilage with long-term sequela including, but not limited to, arthroses, deformity, and amputation of the phalanges. This was a retrospective chart review of pediatric frostbite identified in an in-house burn center registry from March 1999 to March 2014. Therapeutic management included negative pressure wound therapy (NPWT). Three patients (age 16-31 months) had frostbitten hands because they were outside in cold weather without gloves...

The authors present a case of deep frostbite treated with both hyperbaric oxygen and thrombolytic therapies. Both of these therapies are experimental and have not yet achieved widespread clinical use. The patient described in this paper sustained frostbite after becoming intoxicated and falling unconscious in a snowy field. He was treated acutely for hypothermia and came into the authors' care for wound management. Of his 6 digits with extensive, deep frostbite, 1 digit eventually required partial amputation, and another had protracted osteomyelitis treated with intravenous antibiotics...

Cold burns are still exceptional in sub-Saharan Africa. However, the promotion of a wider use of domestic gas (commercial butane) has led to the growth of petrochemical industries. As a consequence, there is an increased risk of the occurrence of such burns (referred to as frostbite). We report a case of a cold burn injury caused by liquefied petroleum gas (LPG) in the workplace. The diagnosis of severity and management later complicated the local evolution. Compliance with safety measures in factories remains the main means of preventing this rarely seen type of burn...
