  Trauma is the leading cause of mortality in patients younger than 18 years, accounting for more than 5000 deaths annually. Although thoracic trauma accounts for only 5-12% of admissions to a trauma center, it is second only to head injury as the most common cause of death. Multisystem involvement is reported in more than 50% of children with thoracic trauma and portends a worse prognosis. The mortality for isolated thoracic trauma is 5% and approaches 20-35% with concomitant abdominal or head injuries, respectively (see Media file 1). SALIENT FEATURES OF PEDIATRIC THORACIC TRAUMASection 3 of 7
Unique features that differentiate childhood thoracic trauma from adult thoracic trauma are listed below and are discussed throughout the article. Key characteristics of childhood thoracic trauma include the following:
INITIAL ASSESSMENT PRIORITIES AND MANAGEMENTSection 4 of 7
An exhaustive review of the patient's airway, breathing, and circulation (ABCs) in childhood trauma resuscitation is beyond the scope of this article, but the principles of resuscitation do not change. Resuscitation of the child with thoracic trauma begins with a survey for immediate life-threatening injury. The most common immediate life-threatening thoracic injuries and potential life-threatening thoracic injuries include the following:
Perform the primary survey and identify the injuries as quickly as possible. The immediate recognition of whether the child is agonal and hemodynamically stable and the knowledge of the mechanism of injury are implicit in the ABCs of resuscitation.
A child who is unstable has vital signs but also has clear signs or symptoms of cardiac or respiratory compromise. Poor skin perfusion (ie, capillary refill >2 s), tachycardia, abnormal chest wall excursions, obvious mental status changes, and, possibly, hypotension all characterize instability in a child. A search for immediate life-threatening injuries is warranted. If injuries are undetected or if diagnosis is delayed, these children may become agonal. THE MANAGEMENT OF SPECIFIC INJURIESSection 5 of 7
Airway InjuryAirway injuries may be the result of oropharyngeal trauma, a foreign body, or pathology directly within the thorax that leads to a shift of the tracheobronchial tree. The 2 hallmarks of airway injury include obstruction and subcutaneous emphysema.Oropharyngeal trauma is typically the result of a crush injury or direct blow. The resulting tracheal mucosal edema may be insidious, and breath sounds must be closely monitored. Inspiratory stridor is the hallmark of airway obstruction at or above the level of the vocal cords. Blood, mucus, vomitus, teeth, or other foreign bodies may cause the stridor. This is a clinical diagnosis and must be emergently recognized and treated with removal of the obstruction. Other signs and symptoms of airway obstruction include agitation, diaphoresis, chest wall retractions, asymmetry of respirations, cyanosis, and, ultimately, bradycardia associated with severe hypoxemia. Expiratory stridor is typically the result of pathology below the cords. Children with blunt trauma who have expiratory stridor should be evaluated for a foreign body aspiration (see Media file 2). Diminished breath sounds, wheezing, and loss of volume depicted on plain chest radiography may not be present. A high index of suspicion is imperative. Objects may not be radiopaque, and bronchoscopy should be performed early to avoid pneumonia. Subcutaneous emphysema can result from tracheal disruption in the neck or thorax (see Media file 3). Any positive pressure during expiration makes subcutaneous emphysema progress. If subcutaneous emphysema is unrecognized after intubation, it can also be worsened by positive pressure from mechanical ventilation. Standard management begins with head positioning, suctioning, in-line cervical spine stabilization, and administration of supplemental oxygen. Obviously, obstruction above the vocal cords must be recognized and removed. Intubation may be necessary, and, if not possible, needle cricothyrotomy or tracheostomy is indicated. Control of the airway in patient who is unconscious must always be the first management step. Rupture of the tracheobronchial tree can be partial or complete, and is relatively uncommon in children because of the elasticity of the chest wall. Subcutaneous air solely in the neck may indicate pathology in the trachea. A persistent air leak after decompression of a pneumothorax is suggestive of a bronchial tear. Typical points of disruption include fixed points such as the carina or segmental branches of the bronchus. These injuries are commonly diagnosed with the aid of a bronchoscope, and the injury's location determines the subsequent treatment approach. However, bronchoscopy frequently leads to an underestimation of the magnitude of the injury. Delays in treatment can be life-threatening because both ventilation and oxygenation can be affected. Nonoperative management may be attempted for small injuries encompass less than a third of the airway circumference. Short longitudinal tears of a single airway are particularly likely to be successfully managed in this manner. Nonoperative management should not be attempted, even if the injury is less than one third of the circumference of the airway, if the air leak is massive and ventilation is difficult. Injuries to the cervical tracheal should be approached via a transverse neck incision. If injury is to the distal trachea or right main-stem bronchus, it should be approached via a right thoracotomy, and localized injury to the left main-stem bronchus should be approached via the left chest. Few patients with complex injury that involves the carina or both main-stem bronchi require cardiopulmonary bypass. Most tracheobronchial injuries can be primarily repaired, provided that the suture line is tension free. Because of the mechanisms of these injuries, blast effect and reduced blood flow to the perimeter of the injury must be suspected, and, if necessary, a widened excision must be performed. After closure of the airway defect, the endotracheal tube should be positioned so that the cuff of the tube does not abut the repair. Moreover, a vascularized tissue flap of pleura, pericardium, or muscle should be used to reinforce the repair. Chest-Wall and Lung InjuriesCompared with adults, children have a greater content of cartilage in their ribs, leading to an elastic and highly compliant thorax. This compliance diffuses the force of impact, leading to fewer rib fractures than result of similar injuries in an adult. Although splitting from pain is common in children, atelectasis is less common due to the propensity of children to cry. Diagnosis of acute rib fractures is made with radiography. Multiple rib fractures in a child should always raise the suspicion of child abuse. Oral analgesics are usually sufficient for pain control. Rarely, an intercostal nerve block may be necessary.Flail segments are defined as 2 or more ribs fractured in 2 or more places. The flail segment results in ventilation-perfusion mismatch, atelectasis, and progressive shunting. In general, patients with an unstable chest wall should be treated with positive pressure and pain control. Bleeding from within the chest is rare in children, mainly because of the low incidence of rib fractures (see Media file 4). However, chest bleeding can be an insidious cause of life-threatening injury. Bleeding is typically from an intercostal vessel or lung parenchyma. Regardless of the source, a hemothorax must be evacuated to avoid atelectasis, ventilation-perfusion mismatch, fibrothorax, and a restrictive lung. Treatment involves tube decompression. Initial hemorrhage of more than 20 mL/kg or continued blood loss of more than 2-3 mL/kg/h for 3 consecutive hours may be an indication for open thoracotomy. Moreover, inability to adequately drain the chest and re-expand the lung is an additional criterion for thoracotomy. The pathology is typically an intercostal vessel or vessels, parenchyma, or chest wall. Lobectomy is far less common than stapling of bleeding or simple wedge resection. Recently, minimally invasive thoracoscopy for trauma has become more widespread. Video-assisted thoracic surgery (VATS) can be used as a diagnostic tool in an acute or subacute hemodynamically stable patient with hemothorax. In certain patients with a large initial drainage or continuing blood loss from chest injury, it may aid in avoiding thoracotomy by visualizing a nonbleeding injury, evacuating hematoma, and allowing tamponade by fully expanding lung or cauterizing or ligating bleeding vessels. Moreover, in patients with empyema after chest injury, thoracoscopy can be effective in completely draining the pleural space and in removal of any organizing peel from the lung.3 Pneumothorax Pneumothorax may result from puncture of the lung by a rib, a penetrating chest wall injury, disruption of the pulmonary parenchyma, or by injury to the tracheobronchial tree. Both simple and tension pneumothorax are not well tolerated in children because of the lack of fixation of the mediastinum. An untreated simple pneumothorax eventually leads to a tension phenomenon (see Media file 5). If the pressure in the pleural space with tension pneumothorax becomes high enough, both respiration and hemodynamics are impaired. Secondary to the increased intrapleural pressure, a shift of the mediastinum occurs. This, in turn, compromises venous return with an obligatory decrease in cardiac output. Pneumothorax is a clinical diagnosis and does not require radiographic confirmation for treatment. Performing needle decompression through the second intercostal space at the level of the midclavicular line followed by tube decompression, or simply proceeding to tube decompression, is the treatment of choice. Chest radiography should follow to confirm tube position and reinflation of the lung. An open pneumothorax associated with a sucking chest wound causes pathophysiology because a path of less resistance is created for tracheobronchial air. To prevent this airflow, the wound must be covered and tube decompression must follow. Pulmonary contusion Pulmonary contusion is the most common thoracic injury in children and represents a defining contrast between children and adults. In contrast to rib fractures in adults after blunt trauma, the kinetic energy of blunt chest trauma is transmitted to the compliant chest wall in children. Thus, both pulmonary contusion and hemorrhage are far more common than pneumothorax.4. Typical chest radiographic findings include multiple opacifications corresponding to intraparenchymal hemorrhage (see Media file 6). Hypoxia from shunting and ventilation perfusion mismatch, in addition to radiographic findings, is characteristic of pulmonary contusion. Successful treatment involves aggressive pulmonary toilet and pain management. Resolution of the contusion within a few days is not uncommon (see Media file 8). Sequelae of pulmonary contusion include pneumonia and posttraumatic pseudocysts, both of which should resolve with antibiotics and time. Pulmonary contusion from a car or truck rollover injury in children is a common phenomenon. Pulmonary injury secondary to penetrating trauma Pulmonary injury secondary to penetrating trauma can vary from small pleural or parenchymal lacerations from a stab wound to massive pulmonary injury secondary to a gunshot wound. The basics of ABCs remain paramount. If the patient has sustained a penetrating missile injury and injury to mediastinal structures is suspected, evaluation of the tracheobronchial tree, esophagus, and great vessels should be performed. Asymptomatic patients with normal chest radiography findings can be safely observed and discharged after an appropriate time interval (minimum of 6 h). Wound exploration of thoracic wounds is not recommended due to the potential to cause pneumothorax and contaminate the pleural space. Most pulmonary lacerations do not require surgery and can be treated with tube thoracostomy. Drainage of pleural space with reapposition of pleural surfaces often tamponades low pressure venous bleeding and seals small air leaks. Absolute indications for surgery include exsanguination and uncontrollable air leak from the chest cavity. If thoracotomy is necessary, parenchymal sparing techniques and nonanatomic resections are preferable. A posterolateral thoracotomy is used to gain access to the hilum of the lung. Lung isolation is obtained with a double-lumen tube or bronchial blocker. As with all thoracotomies for penetrating thoracic trauma, the hilum and pulmonary vessels are controlled early to allow rapid vascular control, should a unsuspected central injury be present. The use of stapling devices with a generous margin around the area of injury should be performed. Persistent bleeding from deep missile injuries can be opened and exposed by inserting the anvil of the linear stapler into the tract and firing the device to perform a tractotomy.5 If extensive tissue loss is apparent, anatomical resection of the injured lobe may be necessary. Air embolism is a potential complication of penetrating lung injury. Seizures and sudden cardiac arrest may be the only clues to this near fatal event. Treatment involves thoracotomy, clamping the hilum, and aspiration of air from the left ventricle and aorta. Penetrating injury to the mediastinum can occur without a pneumothorax. Therefore, a stab wound between the nipples can injure the heart or great vessels without damaging either pleural space. Moreover, because the abdomen begins at the nipple line, pathology below the diaphragm should be ruled out when a stab wound occurs at this level. Traumatic asphyxia Traumatic asphyxia is an entity observed in children because of a flexible thoracic and absence of valves in the venous system of the inferior and superior vena cava. Direct compression of the chest wall may be sustained when a child is involved in a motor vehicle collision or crush injury. At the time of injury, if the glottis is closed and the thoracoabdominal muscles are tensed, the increased intrathoracic pressure is transmitted through the central venous system to organs such as the brain, liver, spleen, and kidneys. Children typically present with subconjunctival hemorrhage and petechiae of the chest, shoulders, and head, which cause them to have a bronzed discoloration (see Media file 7). CNS and pulmonary dysfunction can be associated with traumatic asphyxia, but this is a rare occurrence. These children should be monitored in the ICU for 24 hours because of the potential for airway obstruction secondary to venous hypertension and petechiae generated under the tongue and oropharynx (see Media file 7). Despite the cutaneous manifestations, most of the petechiae disappear in a few weeks. Widened Mediastinum and Aortic DisruptionBlunt trauma can injure the aorta or branches of the aortic arch. Approximately 95% of patients with blunt tears of the thoracic aorta die before reaching the hospital. These are exceedingly rare injuries in children. The typical mechanism, as in adults, is a rapid deceleration injury sustained in a motor vehicle accident, an auto-pedestrian accident, or secondary to a fall from a height. Suspicion of this injury in a stable patient may only come from chest radiography depicting a widened mediastinum (see Media file 8).Criterion for mediastinal pathology includes straightening of the mediastinal borders, with loss of the anteroposterior (AP) window, a mediastinum greater than the diameter of the hemithorax, and a right shift of an orogastric tube off the vertebral column. Radiographic signs of disruption of the aorta, typically at the ligamentum arteriosum, include widened mediastinum, left pleural effusion, apical capping, depression of the left main bronchus, rightward shift of an orogastric tube (off the vertebral column), and fractures of the first or second rib or scapula. Upper-extremity hypertension, interscapular murmurs, and diminished or absent pulses in upper or lower extremities are common physical signs. Aortography is the diagnostic procedure of choice (see Media file 9). CT scanning is an alternative in that it can be rapidly performed in concert with imaging the brain, abdomen, and pelvis. If a contained hematoma is identified, open repair via left posterolateral thoracotomy, either with primary anastomosis or placement of synthetic grafts, is the standard of care. In the acute setting, this is associated with significant morbidity and mortality due to multisystem injury. Delaying intervention with the use of beta-blockers and anti-hypertensive agents until the patient is more stable has improved results, but complications remain high.6. Successful surgical intervention is predicated on achieving proximal and distal control of the aorta. Historically, the "clamp-and-sew" technique was favored. However, due to the potential for ischemic injury to the spinal cord, several adjuncts have been developed to maintain distal aortic perfusion during surgical repair. A heparin-bonded Gott shunt may be used to shunt blood from the proximal aorta to the distal aorta or femoral artery without the use of a pump. Partial left-heart bypass uses a centrifugal pump that draws oxygenated blood from the left atrium, which is reinfused to the distal thoracic aorta or femoral artery. Like the Gott shunt, this technique avoids full systemic heparinization. Nevertheless, both of these techniques require that cannulae be present in the operative field, which often prevents adequate visualization in smaller children. Femoral-femoral cardiopulmonary bypass using an oxygenator maintains lower body perfusion, allows for systemic cooling with spinal cord protection, and allows for easy control hypertension proximal to the aortic cross-clamp. The major disadvantage with this approach is the need for systemic heparinization, which may be a relative contraindication in patients with major associated abdominal injuries or intracranial hemorrhage. Recently, the safety and efficacy of endovascular techniques has been established in adolescents and children. Endovascular stenting allows for definitive treatment of the vascular injury without the need for bypass and reduces the recovery time that is associated with a thoracotomy. Currently, long-term follow-up is required.7 A diagnostic dilemma may result when clinicians encounter a stable transected aorta and associated life-threatening abdominal pathology. In patients with a stable thoracic hematoma, treatment includes evaluation and repair of the abdominal injuries first, followed by a left thoracotomy for management of the transected aorta. As an alternative, the child with a rapidly expanding hematoma of the chest and concomitant abdominal pathology should undergo a thoracotomy before anything else. Cardiac InjuryBlunt injuries of the myocardium range from mild asymptomatic contusion to cardiac rupture.Myocardial contusion Myocardial contusion is the most common injury. The pathology involves reduction in blood flow to a contused cardiac muscle, followed by ischemia. The hallmark of myocardial contusion includes ischemic changes or atrial or ventricular premature contractions or wall motion abnormalities during echocardiography. Sequelae of myocardial contusion are uncommon in patients who demonstrate hemodynamic and cardiac stability upon admission. No reliable standards for diagnosis are known. Other than the presence of dysrhythmias, studies such as creatine kinase–MB (CK-MB) fractions, troponin I, and echocardiography are generally not helpful in either diagnosis or treatment planning. Patients with ectopy or ischemic changes require monitoring in the ICU for 24 hours after injury. Echocardiography is required for any new onset of a murmur. Repair is indicated if ischemia and myocardial dysfunction are severe and salvageable myocardium is found. Myocardial rupture Most patients with rupture of the myocardium do not reach the hospital alive. However, the injury is occasionally contained by the pericardium, and the child presents in shock from a combination of hemorrhage and cardiac tamponade.8. The mechanism of injury is likely sudden severe compression of the chest at the end of diastole. The right ventricle is most frequently involved (46%), followed by the left ventricle (35%), right atrium (26%), and left atrium (6%). The prognosis of left-atrial and right-sided injuries is intermediate, whereas very few survive rupture of the left ventricle. Blunt cardiac rupture is treated surgically via sternotomy or left thoracotomy for isolated left atrial rupture. Penetrating heart wound Penetrating wounds of the heart usually result in 2 pathophysiologic events. Blood may leak from the heart into the pleural space and cause a hemothorax. The diagnosis should be suspected in patients with hemodynamic instability from hemorrhagic shock or persistent bleeding from the chest tube. The other scenario occurs when blood accumulates in the pericardial space. Often the traumatic wound may occlude due pressure in the pericardial space, preventing frank exsanguination. However, the ongoing accumulation of blood more commonly leads to pericardial tamponade. Penetrating wounds can involve any of the 4 chambers of the heart but are most common in the right ventricle due to its anterior location. The presence of hemopericardium on transthoracic echo or subxiphoid pericardial window mandates urgent sternotomy or thoracotomy for repair of cardiac injury. Sternotomy is advantageous because it allows access to all cardiac chambers and, if necessary, institution of cardiopulmonary bypass. Repair should be performed using nonabsorbable sutures with atraumatic needles and pledgets to prevent sutures from pulling through myocardium. Nonmyocardial cardiac injuries are also possible. Rupture of the pericardium can occur with or without associated cardiac injury. Laceration or thrombosis of the coronary arteries from blunt trauma is rare but possible. Diagnosis is made via electrocardiogram and cardiac catheterization. Cardiac tamponade Muffled heart sounds, distended neck veins, and hypotension comprise the diagnostic triad (ie, Beck triad) that defines cardiac tamponade. Subxiphoid needle pericardiocentesis is the treatment of choice. Directing a catheter at a 45° angle toward the left scapula and using a Seldinger technique to maintain the catheter in the pericardial space facilitates continued aspiration of the pericardial sac before emergency left thoracotomy or median sternotomy (depending on the associated pathology). Aspiration of as little as 5 mL of nonclotted blood relieves the tamponade in infants. Time constraints often do not permit application of an alligator clip to avoid puncture of the heart muscle. Radiographic or echocardiographic testing is not needed to make the diagnosis. Commotio cordis Commotio cordis results from a sudden impact to the anterior chest wall that results in cessation of normal cardiac function. The precordial blow that triggers commotion cordis is not usually perceived of a significant magnitude to cause death. The typical scenario is a child who collapses after sustaining a chest blow during a sporting event. Because of the heightened compliance of the pediatric chest, transmission of kinetic energy from the blow to the myocardium occurs. Survival rates have been as low as 15%; however, with the awareness of this condition and increased availability of automatic external defibrillators at schools and athletic facilities, survival for athletes who sustain such injuries should be improved. Specific Injuries and Surgical Strategies for the Heart and Great VesselsOperative approaches to treat specific thoracic injuries are as follows:
Ruptured DiaphragmAn elevated left hemidiaphragm indicates a ruptured diaphragm until proven otherwise. Aids to this diagnosis include the position of an orogastric tube on plain radiograph (see Media file 10). In addition, bowel sounds in the chest are suggestive of the injury. Diaphragm injuries are far more common on the left than on the right because of the protection of the liver; they can go unnoticed, especially in an intubated patient. Moreover, relatively common injuries to the liver obscure suspected diaphragmatic injuries on the right side.9 The diaphragm can rupture in any location, but ruptures of the central tendon and the lateral attachments of the torso wall are the most common.An important lesson for management of a ruptured diaphragm is the possibility of associated abdominal pathology. The abdomen begins at nipple level in children. Therefore, a high index of suspicion is warranted after blunt or penetrating injury. For penetrating injuries at or below the nipple and no apparent pathology on CT scanning of the abdomen, laparoscopy is helpful. Diaphragmatic rupture that results from blunt trauma should be approached through a laparotomy because of the high incidence of intraabdominal solid organ injuries. Occasionally, the diagnosis of blunt rupture of the diaphragm can be initially missed. If the patient is symptomatic and visceral ischemia is a possibility, the approach should always be through the abdomen. A thoracotomy approach may be advantageous for injury or hernias that present in a delayed fashion, especially of the right hemidiaphragm. This approach provides excellent exposure to allow for division of adhesions between trapped viscera and lung parenchyma. When the tear is located, any herniated viscera should be returned to the abdomen and inspected for bleeding or ischemia. The rupture should be repaired with either monofilament nonabsorbable or absorbable sutures. In the event that a tension-free repair cannot be primarily performed, a pedicled intercostal muscle flap can be used to bridge the defect in children.10. Other alternatives include fascia lata, bovine pericardium, or synthetic material such as Gore-Tex or Marlex. If not already present, a chest tube should be placed on the affected side Esophageal PerforationEsophageal injuries can be due to various mechanisms. The most common cause is endoscopic trauma from esophagoscopy, dilation, or transesophageal echocardiography. Other causes include blunt trauma, barometric trauma (eg, Boerhaave syndrome, air-pressure injury), penetrating trauma, caustic injury, or foreign body. Patients with cervical perforations can present with neck pain, cervical dysphagia, dysphonia, or bloody regurgitation. Intrathoracic perforations can rapidly contaminate the mediastinum, leading to chest pain, tachycardia, tachypnea, fever, and leukocytosis.Expeditious diagnosis of esophageal injury is warranted because early diagnosis significantly reduces the rate of complication and mortality. Diagnosis of cervical esophageal perforation is aided by lateral roentgenography, which may reveal air in the prevertebral fascial planes. Plain radiography may reveal mediastinal widening with or without an air-fluid level, subcutaneous emphysema, and a pleural fluid collection. When a leak is suspected, a contrast study should be performed. Water-soluble contrast agents, such as Gastrografin, are advocated for first-line screening. If no perforation is initially detected with a water-soluble agent, the examination should be repeated with dilute barium sulfate. A broad clinical spectrum of esophageal trauma is recognized, ranging from contained small leaks that are recognized early to large leaks with severe mediastinal infection. The general principles of management are directed toward limiting contamination, encouraging healing of the perforation by repair or drainage, and maintaining nutrition of the patient. The treatment algorithm centers on whether preexisting esophageal disease is present and if the perforation is contained or not contained. Rarely, a well-contained leak can be managed with careful observation, nothing by mouth (NPO), broad-spectrum antibiotics, and intravenous feeding. The barium swallow is repeated at weekly intervals. If the leak is not contained, the site of perforation dictates further management. Esophageal injury in the neck, if seen early, is repaired and reinforced with adjacent muscle or tissue and drained. If the leak is seen late, only the abscess is drained without an attempt to repair the injury. Esophageal leaks into the chest are managed by thoracotomy and repair, whether discovered early or late. This is a paradigm shift, in that it was previously felt that late repair was associated with failure and increased mortality. In general, the upper and mid esophagus are best approached through the right side of the chest, whereas the lower third of the esophagus and the esophagogastric junction are best approached through the left side of the chest. Some pleural or intercostal muscular covering should accompany debridement and primary repair. Wide drainage of both the mediastinum and pleural space is mandatory. If inflammation is substantial and if the injury is extensive, cervical esophagostomy is necessary, followed by eventual esophageal replacement. Surgeons should attempt to use the native esophagus in a growing child by all means possible. Recently, video-assisted thoracoscopic drainage for esophageal perforation with mediastinitis in children was demonstrated to be feasible and effective.11. In this study, no mortality was reported in 8 children treated with thoracoscopic mediastinal debridement, with a mean hospital length of stay of 34 days. Delay between onset of primary perforation and hospitalization ranged from 2-12 days (median length, 5.2 d). All patients had a localized collection on contrast study. The authors suggest that the ability of children to heal is stronger than is seen in adults and conclude that perforations in children heal with debridement and drainage alone. Although these data are encouraging, they have not been validated. MULTIMEDIASection 6 of 7
