Rehabilitation of severely injured children.

Injury is the leading cause of death and disability in childhood. Ideal systems of care integrate comprehensive management of acutely injured children with rehabilitation. We review the nature of childhood injury, its disabling consequences, and the best ways to manage the care of children with serious injuries.     

Optimal use of blood in trauma patients

Injury is rapidly becoming the leading cause of death worldwide, and uncontrolled hemorrhage is the leading cause of potentially preventable death. In addition to crystalloid and/or colloid based resuscitation, severely injured trauma patients are routinely transfused RBCs, plasma, platelets, and in some centers either cryoprecipitate or fibrinogen concentrates or whole blood. Optimal timing and quantity of these products in the treatment of hypothermic, coagulopathic and acidotic trauma patients is unclear. The immediate availability of these components is important, as most hemorrhagic deaths occur within the first 3–6 h of patient arrival. While there are strongly held opinions and longstanding traditions in their use, there are little data within which to logically guide resuscitation therapy. Many current recommendations are based on euvolemic elective surgery patients and incorporate laboratory data parameters not widely available in the first few minutes after patient arrival. Finally, blood components themselves have evolved over the last 30 years, with great attention paid to product safety and inventory management, yet there are surprisingly limited clinical outcome data describing the long term effects of these changes, or how the components have improved clinical outcomes compared to whole blood therapy. When focused on survival of the rapidly bleeding trauma patient, it is unclear if current component therapy is equivalent to whole blood transfusion. In fact data from the current war in Iraq and Afghanistan suggest otherwise. All of these factors have contributed to the current situation, whereby blood component therapy is highly variable and not driven by long term patient outcomes. This review will address the issues raised above and describe recent trauma patient outcome data utilizing predetermined plasma:platelet:RBC transfusion ratios and an ongoing prospective observational trauma transfusion study.     

Improving the care of patients with major trauma in the accident and emergency department.

OBJECTIVE--To determine whether improvement in the care of victims of major trauma could be made by using the revised trauma score as a triage tool to help junior accident and emergency doctors rapidly identify seriously injured patients and thereby call a senior accident and emergency specialist to supervise their resuscitation. DESIGN--Comparison of results of audit of management of all seriously injured patients before and after these measures were introduced. SETTING--Accident and emergency department in an urban hospital. PATIENTS--All seriously injured patients (injury severity score greater than 15) admitted to the department six months before and one year after introduction of the measures. RESULTS--Management errors were reduced from 58% (21/36) to 30% (16/54) (p less than 0.01). Correct treatment rather than improvement in diagnosis or investigation accounted for almost all the improvement. CONCLUSIONS--The management of seriously injured patients in the accident and emergency department can be improved by introducing two simple measures: using the revised trauma score as a triage tool to help junior doctors in the accident and emergency department rapidly identify seriously injured patients, and calling a senior accident and emergency specialist to supervise the resuscitation of all seriously injured patients. IMPLICATIONS--Care of patients in accident and emergency departments can be improved considerably at no additional expense by introducing two simple measures.     

Preliminary analysis of the care of injured patients in 33 British hospitals: first report of the United Kingdom major trauma outcome study.

OBJECTIVE--To measure the effectiveness of management of major trauma in the United Kingdom. DESIGN--Review of the care of all seriously injured patients seen over two years. SETTING--33 hospitals which receive patients who have sustained major trauma. SUBJECTS--14,648 injured patients admitted for more than three days, transferred or admitted into an intensive care bed, or dying from their injuries. MAIN OUTCOME MEASURE--Death or survival in hospital within three months of the injury. RESULTS--21% of seriously injured patients (1299) took longer than one hour to reach hospital. Time before arrival at hospital was not related to severity of injury. A senior house officer was in charge of initial hospital resuscitation in 57% (826/1445) of patients with an injury severity score > or = 16. More senior staff were commonly responsible for definitive operations, but only 46% (165/355) of patients judged to require early operation arrived in theatre within two hours. Mortality for 6111 patients sustaining blunt trauma and treated in the 14 busiest hospitals was significantly higher (actual 408, predicted 295.6, p < 0.001) than in a comparable North American dataset. Large differences in the 14 hospitals assessed could not be explained by variations in case load or facilities. In contrast, the outcome of the 4.1% (597) of patients with penetrating injuries was better than that of a comparable group in the United States. Analysis of the 415 penetrating injuries with complete data showed that 15 patients died (19.3 predicted; p = 0.04). CONCLUSIONS--The initial management of major trauma in the United Kingdom remains unsatisfactory. There are delays in providing experienced staff and timely operations. Mortality varies inexplicably between hospitals and, for blunt trauma, is generally higher than in the United States.     

The role of primary bone grafting in complex craniomaxillofacial trauma

The role of craniofacial surgical techniques and immediate bone grafting in the management of complex craniofacial trauma has been reviewed. Four hundred and one patients with complex facial injuries have been treated. Two hundred and forty-one primary bone and cartilage grafts have been performed in 66 patients. Complex facial injuries should be managed by direct exposure, reduction, and fixation of all fractures utilizing interfragmentary wiring. Very comminuted or absent bone is replaced by immediate bone grafting, producing a stable skeleton without the need for external fixation devices. Associated mandibular fractures are managed with rigid internal fixation utilizing A-O technique. Results of immediate bone grafting have been excellent, and complications are rare. All deformities should be corrected, whenever possible, during the initial operation. This one-stage reconstruction of even the most complex facial injuries will prevent severe postoperative traumatic deformity and disability that may be extremely difficult or impossible to correct secondarily.     

INJURIES OF THE HAND AND FOREARM—Treatment of Damaged Soft Tissues

Successful primary repair of soft tissue injuries of the hand and forearm holds the ultimate disability to a minimum. The kinds of trauma and the resultant soft tissue damage may be classified. Attention to details and technique in carrying out the primary reparative operation on the injured hand largely obviates a crippling deformity or the need for much reconstruction later.     

Injuries of the hand and forearm; treatment of damaged soft tissues

Successful primary repair of soft tissue injuries of the hand and forearm holds the ultimate disability to a minimum. The kinds of trauma and the resultant soft tissue damage may be classified. Attention to details and technique in carrying out the primary reparative operation on the injured hand largely obviates a crippling deformity or the need for much reconstruction later.     

Elevation of neutrophil-derived factors in patients after multiple trauma

Trauma represents one of the leading causes of death worldwide. Traumatic injuries elicit a dynamic inflammatory response with systemic release of inflammatory cytokines. Disbalance of this response can lead to systemic inflammatory response syndrome or compensatory anti-inflammatory response syndrome. As neutrophils play a major role in innate immune defence and are crucial in the injury-induced immunological response, we aimed to investigate systemic neutrophil-derived immunomodulators in trauma patients. Therefore, serum levels of neutrophil elastase (NE), myeloperoxidase (MPO) and citrullinated histone H3 (CitH3) were quantified in patients with injury severity scores above 15. Additionally, leukocyte, platelet, fibrinogen and CRP levels were assessed. Lastly, we analysed the association of neutrophil-derived factors with clinical severity scoring systems. Although the release of MPO, NE and CitH3 was not predictive of mortality, we found a remarkable increase in MPO and NE in trauma patients as compared with healthy controls. We also found significantly increased levels of MPO and NE on Days 1 and 5 after initial trauma in critically injured patients. Taken together, our data suggest a role for neutrophil activation in trauma. Targeting exacerbated neutrophil activation might represent a new therapeutic option for critically injured patients.     

Massive and recurrent hernias; use of dermal grafts in carrying out repair

Nonpenetrating abdominal injuries are commonly seen in a general hospital. High speed traffic accidents are responsible for the majority of these injuries. The mortality rate is high. Deaths were from associated injuries, failure to recognize abdominal trauma, hemorrhage and from acute renal insufficiency. Careful observation of every severely injured person, vigorous treatment of hemorrhagic shock with whole blood, and prompt surgical intervention when indicated will improve the mortality figures.     

Common injuries of the athlete's hand.

Hand injuries are among the most frequent accidents seen in sports medicine. All too commonly they are considered trivial since the athlete may continue to participate actively and neglect his injury. The consequent delay in diagnosis and proper treatment may result in long-standing or even permanent disability. This paper describes the more commonly encountered hand injuries, their diagnosis and their optimal treatment. Included are soft-tissue injuries, ligamentous injuries, fractures and tendon avulsions. The basic principles applicable to skeletal and soft-tissue trauma of the hand, which physicians at all levels of sports medicine may encounter, are stressed.     

The periodic health examination: 1. Introduction.

Most cervical spine injuries are due to motor vehicle accidents. Proper extrication of the victims is vital; the ideal device should be easily assembled and applied, should facilitate removal of victims from automobile seats without changing the body''s position, must not hinder airway access or the performance of cardiopulmonary resuscitation, must accommodate all types of patients, including children and obese or pregnant patients, and must completely immobilize the patient, especially if hyperextension is suspected. Current methods of immobilization, such as the use of a soft collar and sandbags, allow neck extension; the short board protects against extension but interferes with airway access. Newer devices are discussed in this article. Injuries of the upper cervical spine are less common but more serious than those of the lower portion and usually involve the vertebral arch. Radiologic examination of the first and second cervical vertebrae and the seventh cervical and first thoracic vertebrae should be emphasized. If lateral and anteroposterior views do not reveal abnormal findings and injury is still suspected, oblique views and computed or conventional tomography should be used. Cervical spinal cord injuries can be minimized or prevented if proper early management is applied.     

2. Newer aids in the diagnosis of blunt abdominal trauma.

The assessment of a case of blunt abdominal trauma can be complicated by many factors, and the resultant inaccurate or delayed diagnoses have contributed to the unacceptable mortality for this type of injury. Recently several useful diagnostic techniques have been developed that, if applied intelligently, may be instrumental in decreasing the high mortality among patients who present with ambiguous abdominal signs after sustaining blunt trauma. Although hematologic investigation and routine radiography have facilitated detection of intraperitoneal injury, peritoneal lavage has become the single most helpful aid. Scanning procedures are sometimes useful in recognizing splenic and hepatic defects especially; these may be confirmed or clarified by angiography. Although ultrasonography may be no more valuable than scintigraphy in outlining splenic and hepatic abnormalities, it is an important technique, especially in the diagnosis of retroperitoneal masses of traumatic origin. Laparoscopy also may be helpful in investigation if surgeons become more familiar with the procedure.     

Resuscitation and coagulation in the severely injured trauma patient

Developments in the resuscitation of the severely injured trauma patient in the last decade have been through the increased understanding of the early pathophysiological consequences of injury together with some observations and experiences of recent casualties of conflict. In particular, the recognition of early derangements of haemostasis with hypocoagulopathy being associated with increased mortality and morbidity and the prime importance of tissue hypoperfusion as a central driver to this process in this population of patients has led to new resuscitation strategies. These strategies have focused on haemostatic resuscitation and the development of the ideas of damage control resuscitation and damage control surgery continuum. This in turn has led to a requirement to be able to more closely monitor the physiological status, of major trauma patients, including their coagulation status, and react in an anticipatory fashion.     

Current concepts in trauma: 1. Principles and directions for development.

Despite considerable advances in treatment in the last 20 years, trauma continues to be the main cause of disability and death for people under the age of 40 years. The outcome after injury has been improved by the introduction of advanced prehospital life support, early transfer and the establishment of specialized programs. Trauma care is governed by two underlying principles: early definitive management and a continuum of treatment from the time of injury to the return to the activities of daily life. Most important, a team approach is necessary in the treatment of the trauma patient. This requires the cooperation and participation of prehospital emergency personnel and referring hospitals as well as multidisciplinary collaboration within each trauma centre. There continue to be areas of neglect that prevent optimal trauma care and must be addressed.     

Lower urinary tract injuries following blunt trauma: a review of contemporary management

Lower urinary tract trauma, although relatively uncommon in blunt trauma, can lead to significant morbidity when diagnosed late or left untreated; urologists may only encounter a handful of these injuries in their career. This article reviews the literature and reports on the management of these injuries, highlighting the issues facing clinicians in this subspecialty. Also presented is a structured review detailing the mechanisms, classification, diagnosis, management, and complications of blunt trauma to the bladder and urethra. The prognosis for bladder rupture is excellent when treated. Significant intraperitoneal rupture or involvement of the bladder neck mandates surgical repair, whereas smaller extraperitoneal lacerations may be managed with catheterization alone. With the push for management of trauma patients in larger centers, urologists in these hospitals are seeing increasing numbers of lower urinary tract injuries. Prospective analysis may be achieved in these centers to address the current lack of Level 1 evidence.

A model of hemorrhagic shock and acute lung injury in Landrace-Large White Swine

Traumatic injury is a leading cause of death worldwide for people between 5 and 44 y of age, and it accounts for 10% of all deaths. The incidence of acute lung injury, a life-threatening complication in severely injured trauma patients remains between 30% and 50%. This study describes an experimental protocol of volume-controlled hemorrhage in Landrace-Large White swine. The experimental approach simulated the clinical situation associated with hemorrhagic shock in the trauma patient while providing controlled conditions to maximize reproducibility. The duration of the protocol was 8 h and was divided into 5 distinct phases-stabilization, hemorrhage, maintenance, resuscitation, and observation-after which the swine were euthanized. Lung tissue samples were analyzed histologically. All swine survived the protocol. The hemodynamic responses accurately reflected those seen in humans, and the development of acute lung injury was consistent among all swine. This experimental protocol of hemorrhagic shock and fluid resuscitation in Landrace-Large White swine may be useful for future study of hemorrhagic shock and acute lung injury.     

Accuracy of single-pass whole-body computed tomography for detection of injuries in patients with major blunt trauma

Background:

Contrast-enhanced whole-body computed tomography (also called “pan-scanning”) is considered to be a conclusive diagnostic tool for major trauma. We sought to determine the accuracy of this method, focusing on the reliability of negative results.

Methods:

Between July 2006 and December 2008, a total of 982 patients with suspected severe injuries underwent single-pass pan-scanning at a metropolitan trauma centre. The findings of the scan were independently evaluated by two reviewers who analyzed the injuries to five body regions and compared the results to a synopsis of hospital charts, subsequent imaging and interventional procedures. We calculated the sensitivity and specificity of the pan-scan for each body region, and we assessed the residual risk of missed injuries that required surgery or critical care.

Results:

A total of 1756 injuries were detected in the 982 patients scanned. Of these, 360 patients had an Injury Severity Score greater than 15. The median length of follow-up was 39 (interquartile range 7–490) days, and 474 patients underwent a definitive reference test. The sensitivity of the initial pan-scan was 84.6% for head and neck injuries, 79.6% for facial injuries, 86.7% for thoracic injuries, 85.7% for abdominal injuries and 86.2% for pelvic injuries. Specificity was 98.9% for head and neck injuries, 99.1% for facial injuries, 98.9% for thoracic injuries, 97.5% for abdominal injuries and 99.8% for pelvic injuries. In total, 62 patients had 70 missed injuries, indicating a residual risk of 6.3% (95% confidence interval 4.9%–8.0%).

Interpretation:

We found that the positive results of trauma pan-scans are conclusive but negative results require subsequent confirmation. The pan-scan algorithms reduce, but do not eliminate, the risk of missed injuries, and they should not replace close monitoring and clinical follow-up of patients with major trauma.Severe trauma is one of the 10 leading causes of burden of disease in North America and Europe.¹ According to a report from the Canadian National Trauma Registry, 14 065 major injuries with an Injury Severity Score above 12 occurred between 2008 and 2009 in the eight provinces that contribute to the National Trauma Registry.² Of these, there were 1605 (11%) deaths, and 212 098 hospital-days resulted.Priority-oriented management requires accurate imaging during resuscitation to avoid missed injuries.^3,4 Standardized algorithms, such as Advanced Trauma Life Support (ATLS), typically comprise physical examination, focused thoracoabdominal ultrasonography and plain radiography of the chest, spine and pelvis, followed by computed tomography (CT) of the head and other selected body areas. The effectiveness of this staged diagnostic approach, however, has been called into question in recent years.^5–9Contrast-enhanced whole-body CT scanning, often referred to as “pan-scanning,” was first proposed in the late 1990s as an alternative to sequential radiologic imaging in trauma settings.¹⁰ Pan-scan algorithms have been shown to accelerate diagnostic work-up, but their effect on survival is controversial.^11–14 Opponents have voiced concerns about the overexposure of patients to radiation with the increasing and often uncritical use of CT scanning.¹⁵We designed the PATRES (Pan-Scan for Trauma Resuscitation) study to assess the accuracy of the pan-scan in detecting injuries to different body regions in patients with suspected major blunt trauma.     

Early Management of the Critically Injured

A plan for the early management of the critically injured patient is described with emphasis on the priorities of management of injuries to certain organ-systems. The most important priorities are the establishment and maintenance of adequate ventilation and adequate circulation. The general surgeon is best qualified to assume full responsibility for the proper care of the critically injured, of patients with multiple injuries, and of patients in traumatic shock. He must assume the risk of transfusing unmatched whole blood and of deferring non-essential radiographs. The emergency and radiology departments may have to be by-passed to save the life of the critically injured patient. The measures required to establish a clear airway, to treat complications which can impair ventilation, to manage shock and hemorrhage and the possible complications of massive transfusions of blood are reviewed.
