[Modern integrated approach to surgical treatment of patients with defects and deformations following high-voltage electrical injury]. / Sovremennyi kompleksnyi podkhod v khirurgicheskom lechenii patsientov s defektami i deformatsiyami v rezul'tate vysokovol'tnoi elektrotravmy.

OBJECTIVE: To develop the algorithm for correction of defects following high-voltage electrical trauma with revascularized autografts, to assess the incidence and risk factors of postoperative complications. MATERIAL AND METHODS: Surgical interventions were performed in 16 men. Autografts were selected considering localization of defect and preoperative ultrasound data on perfusion of donor and recipient areas. We applied a sample with temporary compression of the vessels and ultrasound scanning of arteries and veins (a small-sized Doppler sound indicator of blood flow velocity - MINIDOP, BIOSS). RESULTS: Nine patients underwent microsurgical transplantation of revascularized flaps. Six patients with electrical trauma of the upper extremities underwent transplantation of free skin autografts and transposition of flexor and extensor muscles of the fingers in various combinations. In 1 patient, simultaneous microsurgical graft transplantation and plasty with local tissues were carried out. Microsurgical transplantation of thoracodorsal flap was performed in 2 patients with maxillofacial defect (with preliminary deepidermization of the flap in one case). In 3 patients with traumatic amputation of the penis, 2 patients underwent phalloplasty with a thoracodorsal flap and prefabrication of a radial forearm graft at the first stage. At the next stage, urethroplasty with a prefabricated radial forearm graft was performed. In 1 patient, closure of the penis defect was carried out using scrotal flaps. CONCLUSION: An integrated surgical approach, the use of free revascularized autografts and adequate postoperative management ensure high-quality aesthetic and functional restoration, improvement of the quality of life and social adaptation of patients with defects and deformations following high-voltage electrical injury.

Thomas A. Swift's Electric Rifle Injuries to the Eye and Ocular Adnexa: The Management of Complex Trauma.

PURPOSE: To report the ocular and adnexal injuries sustained by patients with Thomas A. Swift's electric rifles (TASER; TASER International, Scottsdale, AZ), review the literature, and discuss the management of this complex trauma. DESIGN: Multicenter, retrospective case series and literature review. PARTICIPANTS: Seventeen eyes of 16 patients (5 eyes of 5 patients treated at 3 institutions, and 12 eyes of 11 previously reported cases). METHODS: The clinical data of 17 eyes were pooled. Spearman's correlation coefficient was used to assess the association between the extent of TASER injury and patient outcomes. MAIN OUTCOME MEASURES: Extent of TASER injury (zone of injury, penetrating vs. perforating) and association with patient outcomes (visual acuity [VA] and retinal detachment [RD]). RESULTS: In our cohort, 4 patients were transported by law enforcement and 1 was transferred from a community hospital. Four patients were taken to the operating room for TASER removal and globe repair; 1 patient underwent removal in the emergency room. Of 17 pooled cases, 12 (71%) involved open-globe injury. Of these, there was a high rate of zone 3 injuries (100%; n = 12) and a high incidence of RD (73%; 8 of 11, eviscerated eye excluded). Among patients with closed-globe injury (n = 5), 1 patient demonstrated exudative RD and 1 patient demonstrated retinal dialysis with RD. Of 10 patients with RD, 1 (10%) achieved resolution with monitoring (exudative RD); 1 (10%) underwent cryopexy and pneumatic retinopexy; 3 (30%) underwent vitrectomy, and 5 (50%) with poor prognosis did not undergo vitreoretinal surgery. In the 3 patients who underwent vitrectomy, all 3 (100%) demonstrated redetachment resulting from proliferative vitreoretinopathy and required additional surgery. Visual acuity on presentation was significantly correlated with final VA (ρ = 0.783; P = 0.02). Men (94%) were more likely than women (6%) to sustain TASER trauma. Median age was 26 years. There was a 50% rate of loss to follow-up. CONCLUSIONS: Thomas A. Swift's electric rifle injuries to the eyes or ocular adnexa represent complex trauma. Zone 3 injuries are common. The visual prognosis is guarded, and eyes may require multiple surgeries to preserve vision. Patients are at high risk for loss to follow-up by way of incarceration.

Posterior capsular rupture and spontaneous posterior dislocation of lens following electrical injury.

Lenticular changes are often seen following electrical injury. We report an unusual case of electrical injury with late spontaneous posterior dislocation of lens nucleus with intact anterior capsule with ruptured posterior capsule in the right eye and anterior subcapsular cataract in the left eye. The right eye was managed with pars plana vitrectomy with cortical matter removal with multipiece intraocular lens insertion in ciliary sulcus. This report adds posterior capsular rupture and posterior dislocation of lens to the usual ocular complications of electrical injury.

Early laparotomy and timely reconstruction for patients with abdominal electrical injury: Five Case Reports and Literature Review.

INTRODUCTION: High-tension electricity can cause devastating injuries that may result in abdominal wall loss, visceral damage, and sometimes major threat to life. The visceral organ may be exposed after debridement and require flap cover, but the tensile strength of abdominal wall may be lack even if flap transplanted. METHODS: From April 2007 through May 2015, 5 patients with severe abdominal electrical injury were treated at our hospital. Exploratory laparotomy was performed based on their clinical manifestations and debridement findings of abdominal wall at early stage, and decision regarding technique for reconstruction of abdominal wall was based on an assessment of the location and extent of the defect. Medical records were reviewed for these data. RESULTS: Clinical evaluation and debridement findings of the abdomen revealed 4 patients with suspicious visceral damage. Laparotomy was performed in 4 cases, and revealed obvious lesion in 3 cases, including segmental necrosis of small intestine, partial necrosis of diaphragm, left liver and gastric wall, and greater omentum. Five patients underwent abdominal wall reconstruction using island retrograde latissimus dorsi myocutaneous flap or free/island composite anterolateral thigh myocutaneous flap. All flaps survived, abdominal bulging occurred in 3 cases after follow-up of 12 to 36 months. CONCLUSIONS: The clinical manifestations and wound features of abdomen collectively suggest a possible requirement of laparotomy for severe abdominal electrical burns. Retrograde latissimus dorsi myocutaneous flap or composite anterolateral thigh myocutaneous flap is an effective option for reconstruction of abdominal wall loss, the long-term complication of abdominal bulging, however, remains a significant clinical challenge.

A 3-Phase Approach for the Management of Upper Extremity Electrical Injuries.

Upper extremity electrical injuries present with unique pathophysiologic considerations due to the differing mechanisms of injury produced by the electromagnetic field. The initial phase of treatment consists of recognition of other life-threatening injuries, stabilization of patients, and multisystem resuscitation. The second phase of treatment consists of excising devitalized tissue, appropriate wound care to prevent delayed infection, providing temporary and definitive coverage over vital structures, and preventing contracture and joint stiffness via aggressive therapy. The final phase of treatment consists of sensorimotor functional reconstruction via nerve grafting and tendon transfers available based on patients' deficits and available redundant sources.

Preliminary Investigation of Pain-Related Changes in Cerebral Blood Volume in Patients With Phantom Limb Pain.

OBJECTIVE: To investigate changes in the pain network associated with phantom limb pain, magnetic resonance imaging (MRI) was used to measure cerebral blood volume (CBV) in patients who had undergone unilateral arm amputation after electrical injury. DESIGN: Case-controlled exploratory MRI study of CBV via MRI. SETTING: University hospital. PARTICIPANTS: Participants (N=26) comprised patients with phantom limb pain after unilateral arm amputation (n=10) and healthy, age-matched persons (n=16). INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: The intensity of phantom limb pain was measured using the visual analog scale (VAS). Depressive mood was assessed using the Hamilton Depression Rating Scale, and cognitive function was assessed using the Korean version of the Mini-Mental State Examination. Voxel-wise comparisons of relative CBV maps were made between amputees and controls over the entire brain volume. The relationship between individual participant CBV (measured in voxels) and VAS score was also examined. RESULTS: Compared with control participants, amputees exhibited greater degrees of depression; significantly higher CBV in the bilateral medial frontal area (orbitofrontal cortex [OFC] and pregenual anterior cingulate cortex [pACC]); and significantly lower CBV in the right midcingulate cortex, posterior cingulate cortex, and primary somatosensory cortex. CBV increased in the contralateral and ipsilateral hemispheres of the amputated arm, regardless of the amputation side. This CBV increase in the OFC and pACC was strongly correlated with pain intensity in all amputees. CONCLUSIONS: We observed increased CBV in regions associated with emotion in the cerebral pain network of patients who had undergone unilateral arm amputation after electrical injury. This study suggests that CBV changes were related to neuroplasticity associated with phantom limb pain.

[Cataract development after electrical injury]. / Kataraktentwicklung nach Stromverletzung.

Cataract development is one of the most common complications of ocular electrical injury. Our patient reported an electrical injury of his face 13 years ago that affected both eyes. Since that time he noticed progressive visual impairment of both eyes. At the time of first presentation in 2014, slit lamp examination showed characteristic opacities within the anterior and posterior subcapsular area of the lens. Cataract surgery led to full recovery of visual acuity.

Bilateral ultrasound-guided supraclavicular block in a patient with severe electrocution injuries of the upper extremities.

The performance of bilateral supraclavicular brachial plexus nerve blocks is controversial. We present the challenging case of a 29-year-old male who suffered bilateral high-voltage electrocution injuries to the upper extremities, resulting in severe tissue damage, sensory and motor deficits, and wounds in both axillae. This injury necessitated bilateral below-elbow amputations. His postoperative course was complicated by pain refractory to intravenous narcotics. The decision was made to attempt bilateral supraclavicular brachial plexus blocks. Our concerns with this approach included the risks of pneumothorax and respiratory failure due to phrenic nerve block. Initial attempts at brachial plexus blockade using nerve stimulation were unsuccessful; therefore, ultrasound guidance was employed. With vigilant monitoring in an intensive care unit setting, we were able to safely perform bilateral continuous supraclavicular brachial plexus nerve blocks with an excellent analgesic response and no noted complications.

Understanding the burden and outcome of trauma care drives a new trauma systems model.

BACKGROUND: The Pietermaritzburg Metropolitan Trauma Service (PMTS) attempts to provide care for a whole city and hence is referred to as a service rather than a center. As part of a multifaceted quality improvement program, the PMTS has developed and implemented a robust electronic surgical registry (ESR). This review of the first year's data from the ESR forms part of a situational analysis to assess the burden of trauma managed by the service and the quality of care delivered within the constraints of the available resources. METHODS: Formal ethical approval was obtained prior to design and development of this study, and appropriate commercial software was sourced. The exercise of data capture was integrated into the process of service delivery and was accomplished at the endpoint of patient care. 12 months after implementation of the registry, the data were extracted and audited. RESULTS: A total of 2,733 patients were admitted over the 12 month study period. The average patient age was 28.3 years. There were 2,255 (82.5 %) male patients and 478 (17.5 %) female patients. The average monthly admission rate was 228 patients, with a peak of 354 admissions over the December period. The mean injury severity score (ISS) was 12 [interquartile range (IQR) 6.7-23.2]. A quarter (24.8 %) of all new emergency admissions had an ISS > 15. The average duration of stay for patients was 5.12 days (IQR 2.3-13.2 days). Some 2,432 (92.1 %) patients survived, and 208 (7.9 %) died. A total of 333 (13 %) patients required admission to either the intensive care unit (ICU) or the high dependency unit. From the city mortuary data a further 362 deaths were identified. These included 290 deaths that occurred on scene and 72 that occurred within Pietermaritzburg hospitals other than Greys and Edendale. The total trauma-related mortality for the entire city in 2012 was 570 (51 % on-scene deaths and 49 % in-hospital deaths). Blunt trauma accounted for 62 % of deaths. CONCLUSIONS: The PMTS treats a significant volume and spectrum of trauma. Despite significant resource limitations, we have managed to implement a functional and sustainable trauma service across multiple hospitals. We believe the major resource deficits limiting our service could be ameliorated by the development of an additional trauma facility, adequately equipped with dedicated trauma operating slates and trauma ICU beds. The adoption of our current model of trauma care came out of a need to work within our resource constraints, and it differs from the traditional model. Within the aforementioned limits, our data suggest that this model of delivering care is feasible, practical, and successful. Considering the universal burden of trauma and the all-too-common imbalance between resource demand and supply among many health-care institutions, it is our hope that this report will contribute to the ongoing academic debate around the topic of optimal systems of providing global trauma care.

Electrocutions--treatment strategy (case presentation).

Electrical injuries are a form of trauma with extreme gravity and a unique pathophysiology: they affect the entire organism. A wide range of voltages may cause electrical accidents. Complications should be anticipated and prevented in order to minimize the complication risk and assure a vital, functional and esthetic prognosis as good as possible. The article presents a case treated in our clinic together with the unique particular clinical situation and algorithm that led to a favorable result.

Secuelas posquemaduras en un paciente doble conductor de la electricidad industrial / Post burn sequels in a patient who is double conductor of industrial electricity

Paciente del sexo masculino de 43 años de edad, con antecedentes de hipertensión arterial, que hace contacto con los cables de alta tensión (33 000 V); el sitio de entrada de la electricidad se produjo por dos regiones, lo cual causó lesiones del 30,80 por ciento de superficie corporal quemada y pronóstico de vida crítico; las zonas de salida fueron ambos calcáneos. Se decidió ingreso del paciente en Terapia Intensiva de Caumatología. Por la complejidad de las lesiones de las puertas de entrada, se amputó de urgencia la mano izquierda y a las 48 h el dedo pulgar de la mano derecha. Por la profundidad de las quemaduras, se requirió varias intervenciones: amputaciones, necrectomías y autoinjertos de piel. La estadía hospitalaria fue de 125 días. Hubo daño irreversible de todos los nervios de la mano derecha, con impotencia funcional total. La inmediatez de la atención especializada por un equipo interdisciplinario salva la vida del paciente, con secuelas estéticas y funcionales. La electricidad produce lesiones severas que requieren de un manejo integral y cuando la puerta de entrada es múltiple, se incrementa la complejidad del caso(AU)

A 43 years old male patient with antecedents of high blood pressure that makes contact with high voltage cables (33 000 V) was taken to hospital. The input site of electricity was produced in two regions of the body, causing lesions of a 30,80 percent of burned body surface and a critical prognosis for his life; being the calcanei the output sites. It was decided to admit the patient to the Intensive Care Burn Unit. Due to the complexity of the lesions in the input sites, his left hand was amputated as an emergency treatment and 48 hours later, the thumb of his right hand was amputated, too. Because of the depth of burns, several interventions were required: amputations, necrectomies, and skin autografts. He was in hospital for 125 days. He had irreversible damage of all the nerves of the right hand, with total functional impotence. The immediacy of the specialized attention given by a multidisciplinary staff can save a patient's life, leaving functional and aesthetic sequels. Electricity produces severe lesions that require a comprehensive management and, when the input site is multiple, the complexity of the case is higher(AU)

Bilateral four-part anterior fracture dislocation of the shoulder--a case report and review of literature.

Although bilateral anterior dislocation of shoulder is not that uncommon, there have been only 12 published reports on bilateral anterior fracture dislocation of shoulder. The associated fractures have mostly been greater tuberosity fractures with bilateral three part fractures being reported in only two cases. To our knowledge, a bilateral four part anterior fracture dislocation of the shoulder has not yet been reported in the English literature. We here report a case of bilateral anterior fracture dislocation with four part fracture of both proximal humeri in a 60-year-old male due to electrocution. Considering the comparatively old age of the patient and excessive comminution of both the fractures, a bilateral hemiarthroplasty was done. At the last follow-up after more than 2 years, the patient was pain free with ability to comfortably carry out most of the activities of daily life. Through our case report, we highlight the rarity of the condition and review the available literature on the subject. We also emphasize the importance of meticulous perioperative planning when dealing with such cases to ensure a satisfactory long-term outcome.

Missed posterior shoulder dislocation and McLaughlin lesion after an electrocution accident.

Posterior shoulder dislocation is a rare event that may occur after a direct trauma, an epileptic seizure, electric shock or electroconvulsive therapy. In more than 50% of the cases, posterior dislocations are missed on initial evaluation and often misdiagnosed as frozen shoulders with unfortunate consequences. We present the case of a missed posterior subluxation and reverse Hill Sachs lesion (McLaughlin lesion) in a 40-year-old woman caused by anelectric shock of 240 V. The patient underwent surgery in our institute two weeks after the injury. The humeral head was reduced and the reverse Hill Sachs lesion was filled by demineralized bone matrix allograft with osteoinductive factors. Tendons were repaired and a temporaneous artrodesis was performed. At the final follow up of 12 months, we obtained a Costant Score of 93 and the patient returned to her previous daily activities.

Renal artery thrombosis following an inappropriate implantable cardioverter defibrillator shock.

In spite of technological advances, the incidence of inappropriate therapies continues being high. Usually, the most direct consequence of inappropriate shocks is impairment on quality of life parameters, but in some cases the consequences may be unpredictable. We report on a case of renal artery thrombosis, following an inappropriate implantable cardioverter defibrillator shock.

Thoracoscopic patch insulation to correct phrenic nerve stimulation secondary to cardiac resynchronization therapy.

AIMS: Cardiac resynchronization therapy is an established therapy for heart failure, improving quality of life and prognosis. Despite advances in technique, available leads and delivery systems, trans-venous left ventricular (LV) lead positioning remains dependent on the patient's underlying venous anatomy. The left phrenic nerve courses over the surface of the pericardium laterally and may be stimulated by the LV pacing lead, causing uncomfortable diaphragmatic twitch. This paper describes a video-assisted thoracoscopic (VATS) procedure to correct phrenic nerve stimulation secondary to cardiac resynchronization therapy. METHODS AND RESULTS: Most current ways of avoiding phrenic stimulation involve either electronic reprogramming to distance the phrenic nerve from the stimulation circuit or repositioning the lead. We describe a case where the phrenic nerve was surgically insulated from the stimulating current by insinuating a patch of bovine pericardium between the epicardium and native pericardium of the heart thus completely resolving previously intolerable and incessant diaphragmatic twitch. The procedure was performed under general anaesthesia with single-lung ventilation and minimal use of neuromuscular blocking agents. Surgical patch insulation of the phrenic nerve was performed using minimally invasive VATS surgery, as a short-stay procedure, with no complications. No diaphragmatic twitch occurred post-surgery and the patient continued to gain symptomatic benefit from cardiac synchronization therapy (New York Heart Association Class III to II), enabling return to work. CONCLUSIONS: In cases where the trans-venous position of a LV lead is limited by troublesome phrenic nerve stimulation, thoracoscopic surgical patch insulation of the phrenic nerve could be considered to allow beneficial cardiac resynchronization therapy.

Intensity and localization of trauma in non-fatal electrical injuries.

BACKGROUND: Electrical injuries currently remain a worldwide problem. In Turkey, burns are relatively small in number among injuries overall, but they continue to be a major public health problem. Electrical injuries may occur due to high- or low-voltage contact. Injuries due to low voltage usually occur at home. High-voltage injuries are usually work-related and result from a shorter contact, but may cause serious tissue destruction and secondary injuries. METHODS: The objective of this study was to review a medical institution's experience with electrical injuries between 1997-2005. The institution admitted 55 electrical injury cases throughout this period. A computerized burns registry was used for data collection and analysis. RESULTS: The burn causes differed among age groups and between the sexes, with males constituting 89.1% of the electrical burn patients. Forty-one of the injuries were due to high voltage whereas 14 injuries were due to low voltage. Complications were most common in the high-voltage group. Mean length of stay was longest in this group, at 33.69+/-21.13 days, and the patients in this group also required the most operations. CONCLUSION: Work-related activity was responsible for the majority of these high-voltage injuries, with the most common occupations being linemen and electricians. These patients tended to be younger men in the prime of their working lives. Our study underlines the need for stronger efforts aimed at prevention, such as better public education and strict regulations regarding the distribution and use of electricity.

Microsurgical reconstruction of the burned hand.

Although most thermal injuries to the hand can be successfully managed with excision and grafting, deeper injuries may require microsurgical techniques to provide stable, durable coverage and the optimal functional result. In delayed reconstruction, thin pliable flaps can be used to resurface the hand or allow for contracture releases. Proper patient and procedure selection are critical to the success of microsurgical reconstruction.

Humane killers, human injury: functional outcome of vole captive bolt injuries.

BACKGROUND: High-pressure blast injuries to the hand due to vole captive bolt devices are serious injuries that are to a great extent unknown to emergency care operators and trauma surgeons. There is no study on the functional outcome of these patients. METHODS: We assessed the functional outcome of patients with injuries inflicted by vole captive bolt devices. Therefore, a protocol consisting of a physical examination and an assessment of static muscle power (grip and pinch strength) was performed. To capture the subjective experience of patients regarding their injury related disability and impairment, the DASH follow-up questionnaire was used. Based on clinical/radiologic findings and outcome, a classification of this unique subgroup of blast injuries was developed. RESULTS: The functional outcome of 34 patients suffering hand injuries due to captive bolt devices between 2004 and 2007 was assessed. A significant reduction of static muscle testing parameters compared with the uninjured hand was revealed. Fourteen patients lost a digit. Average time lost from work was 5.4 weeks. CONCLUSION: Vole captive bolt device-related hand injuries are followed by deterioration of hand function. The present observations alarmed national authorities. The manufacturers were required to take engineering and teaching measures to rule out handling errors that were identified as leading cause of injury.

[Ten years of hand transplantation experiment or routine?]. / Zehn Jahre Handtransplantation Experiment oder Routine?

In the 20th century the legend of Cosmas and Damian - an extremity being transferred from one person to another - became reality. The first hand transplantation was carried out in 1964 in Ecuador but the hand had to be removed again within three weeks due to rejection. Although he was the first one to be treated with more modern immunosuppressants, the same fate overtook another patient who received a hand from a brain-dead donor in 1998 in Lyon. Since then only 32 persons worldwide have been provided with parts of the upper extremity. The partly published histories of three patients who have had both hands transplanted will be summarised and indication critically assessed once again. It is also stressed how difficult, multi-layered and complex the patient's education is. The patient has to be informed in many conversations beforehand about every stage of therapy but also about possible complications and even rejection. Can the psychological burden/stress while waiting for a donor, the difficult post-operative period, lifelong adherence to a rigorous drug-regimen, the complexity of the whole procedure be made comprehensible to a layman? To replace same with same is the goal of the best-possible reconstructive surgery. It is to hope that through future innovations in the immunosuppressing therapy patients can be offered transplantation of one or both hands as a routine-operation. Until then indication has to be strict and the operation can possibly only be performed in a few centres. Long-time prospects, disadvantages and complications, as well as side effects have to be presented openly.
