Management of the choking child

PEANUTS: a national survey on the management of pediatric tracheobronchial foreign bodies

To assess the different types of management of pediatric foreign body aspirations in order to help define guidelines, depending on clinical presentation. A national survey in France was emailed to all 30 university-affiliated departments of otolaryngology-head and neck surgery and pediatric pulmonologists in France. Data concerning the center and the experience of each participant were collected in order to define an "senior expert" group with experience of extracting more than 10 foreign bodies and a "junior/non-expert" group. Both groups answered questions concerning five clinical cases of foreign body aspiration of different severities. Ninety-eight participants answered this survey (75 otolaryngologists and 23 pulmonologists), representing 28 of the 30 university-affiliated departments in France with a completion rate of 89%. Responses of the senior expert group were similar for clear-cut situations, such as an asymptomatic child with a low probability of foreign body aspiration and for a symptomatic child with respiratory distress. However, for intermediate situations, management varied significantly according to the physician when considering clinical, radiological, and surgical management. In comparison to the senior expert group, the junior non-expert group seemed more precautious in the management of foreign body aspiration for intermediate cases, in particular, concerning the time at which extraction was performed.  Conclusion: The management of foreign body aspiration depends on the physician's experience and the center's habits. In order to optimize patient care for foreign body aspiration, we suggested a management algorithm based on the senior expert group responses. What is Known: • Foreign body aspirations (FBA) are dreaded by pediatricians, pediatric otolaryngologists, and pulmonologists particularly because of the potential fatal outcome. • However, consensus concerning their management is not clearly defined in the literature. What is New: • This study is the first to evaluate the management of foreign body aspirations (FBA) from the clinical assessment by the emergency medicine physician to the extraction of the foreign body. • A management algorithm was designed and secondarily validated by the SE group to help to emergency medicine physician and specialist to manage FBA.

Flexible Fiberoptic Bronchoscopy in the Intensive Care Unit

For the past 20 years, flexible fiberoptic bronchoscopy (FOB) has been shown to be an important procedure in the diagnosis and management of patients in intensive care units (ICU). In adults, FOB is used therapeutically to remove retained secretions and to correct atelectasis not improved by conservative means. In the pediatric population, however, FOB is mainly used to diagnose tracheal disease in critically ill children. The principal risks of FOB are hypoxemia and dysrhythmias; hemor rhage and pneumothorax may occur as a result of biopsy procedures. In competent hands, these adverse compli cations of FOB are minimal. Although rigid bronchos copy remains pivotal in most pediatric bronchoscopic procedures, massive hemoptysis, foreign body removal, and laser therapy for occluding tumors of the upper airway, flexible FOB has an increasingly important role in the diagnosis and management of these disorders.

Suspected foreign body inhalation in children: what are the indications for bronchoscopy?

OBJECTIVE

To define the criteria for bronchoscopy in children with suspected foreign body (FB) inhalation.

STUDY DESIGN

Health history, physical examination, and radiologic examination were performed before bronchoscopy in all children referred for suspected FB inhalation between 2003 and 2005.

RESULTS

A total of 142 children, ranging in age from 3 months to 14 years (median age, 20 months), were referred with a history of suspected FB inhalation. An FB was found in 42 children with abnormal physical and radiologic findings, in 17 children with abnormal physical or radiologic findings, and in 2 children with normal physical and radiologic finding but persistent cough. Bronchoscopy revealed no FB in the children with normal physical and radiologic examinations and no symptoms (n = 16).

CONCLUSION

In children with a history of choking, bronchoscopy is mandatory in the presence of persistent symptoms, such as cough, dyspnea, and fever, or any abnormal physical or chest radiography findings. Bronchoscopy is not necessary in asymptomatic children with normal physical and radiographic examinations.

Deaths Associated with Choking in San Diego County

Death from choking is the fourth most common cause of unintentional-injury mortality, but little data are published on causes or locations of these episodes. These deaths typically are peaked at the extremes of age, with young children and the elderly having the greatest rate of fatal choking. Our objective was to characterize the causes of fatal airway obstruction in adults. The San Diego County Medical Examiner's database was searched for deaths attributed to choking in decedents 18 years and older during the 10-year period from 1994 to 2004. Data were abstracted regarding the underlying medical conditions, items choked on, location of the choking, and treatments involved in the individual cases. We found 133 victims who died from choking, with 14% having using alcohol or other sedatives and 55% having a documented neurological deficit or anatomic difficulty with swallowing. The most common specified food objects that victims choked on were meat products, and 45% occurred at home, followed by 26% at supervised facilities, and 14% at restaurants. Of the 19 choking episodes occurring in restaurants, only one employee was documented to attempt a resuscitative effort. Most victims who choked to death had an underlying neurological deficit, and occurred at home or supervised facilities appear to have an appropriate initial-response intervention.

Lower respiratory tract foreign bodies: a retrospective review of morbidity, mortality and first aid management

OBJECTIVES

The authors describe 28 pediatric cases of foreign body inhalation requiring treatment in intensive care units between 1987 and 1999. The purpose of this study was: (1) to analyze the circumstances, diagnostic difficulties and initial treatment of serious foreign bodies and (2) to compare our series with other literature descriptions and define principles for optimal prevention and initial treatment.

METHODS

Twenty-one children presented a penetration syndrome, which was responsible in 13 cases for asphyxia with cardiorespiratory arrest. All these children died, regardless of the initial treatment. Seven children were hospitalized for apparent asthmatic symptoms that did not respond to traditional treatment.

RESULTS

The inefficiency of external extraction methods like the Heimlich maneuver and the mean delay between clinical signs and initial treatment lead us to propose a new strategy for the emergency treatment of foreign bodies with asphyxia.

CONCLUSIONS

We recommend that emergency teams promote the use of a laryngoscope and Magill forceps. Flexible endoscopy is still recommended as the appropriate diagnostic tool to eliminate doubt in the case of a first severe asthma attack.

Teaching teachers about school health emergencies

The passage of laws requiring that all children receive appropriate public education in the least restrictive environment means children with special health care needs who are at increased risk for health emergencies have entered regular public classrooms. Therefore, teachers must deal not only with health emergencies of normal children, but with emergencies of children with special health care needs. The purpose of this study was to evaluate the effectiveness of a nurse-led educational intervention for 324 teachers on their knowledge of and anxiety about management of children having health emergencies. The intervention resulted in increased knowledge and decreased anxiety about emergency response. This study demonstrated the feasibility and value of nurses educating teachers about school emergencies and in placing the individual health care plan into action.

Spontaneous expulsion of unusual tracheobronchial foreign body

An extremely rare case of long, thin and sharp pin in a young boy which was inhaled initially and defied removal at branchoscopy was eventually recovered in stool after a long and variable course through alimentary tract has been reported.

Tracheobronchial foreign bodies in relation to feeding practices in young children

Tracheobronchial foreign bodies, which are common in children, are a leading cause of accidental deaths in children under four years of age. Three cases of tracheobronchial foreign bodies in children less than two years old are described. One of the foreign bodies was unsuspected; the other two were probably related to food habits. All three cases improved without sequelae following prompt bronchoscopic intervention. Young children should not be given food containing bones or hard chitinous shells.

Pediatric tracheobronchial foreign bodies: historical review from the Johns Hopkins Hospital

We investigated changing trends in pediatric tracheobronchial foreign body removal and resident experience from 1939 to 1991. We retrieved the records of 234 cases of tracheobronchial foreign body removal at Johns Hopkins. The mean number of cases per year was 5.9. The most common foreign bodies removed were peanuts, accounting for 38.9%. The average yearly incidence of pediatric tracheobronchial foreign bodies remained relatively constant during the period studied. Our data suggested little change in outcome or complications with the advent of optical telescopes in the mid-1970s, despite their great value in improved visualization. Resident experience and training were evaluated by the number of cases attended by each resident during his or her training. The number varied from 1 to 8 cases, not including experience acquired at our sister institutions. Although complete data could not be obtained in many of the older medical records, our review suggests that despite the advantage offered by the optical forceps technology, proper training and experience in traditional rigid endoscopic techniques is still crucial to optimize outcome and minimize the risk of complications in pediatric tracheobronchial foreign body removal. Chevalier Jackson's recommendation that residency training include an animal laboratory course in foreign body removal still applies.

Aspirated foreign bodies in the respiratory tract of children: eleven years experience with 127 patients

During 10 years, 127 children were admitted to the pediatric ward because of aspiration of foreign bodies (0.56% of all admissions). Eighty-one percent of the children were under 3 years of age. One hundred and one children (80%) had a positive history of foreign body aspiration. Vegetable substances, particularly peanuts and grains, were the commonest type of foreign body removed. Clinical signs and radiological studies were, in most children, pathognomonic, but sometimes not conclusive. Chest X-rays were normal in 18%; fluoroscopy was diagnostic in 92%. Rigid bronchoscopy and subsequent removal of the foreign body was the treatment instituted. Pneumonia (the commonest complication) developed before and after bronchoscopy in 28% of the children. Pneumomediastinum and subcutaneous emphysema were present on admission in 2 children. Cardiac arrhythmias, bronchospasm, and cardiac arrest were recorded during bronchoscopy. Bronchiectasis developed in one, and persistent intractable pneumonia, requiring lobectomy, developed in another patient. One death occurred.

Foreign body aspiration in children. The diagnostic value of signs, symptoms and pre-operative examination

One hundred and fifteen patients, between 6 months and 12 years of age, had bronchoscopy on suspicion of foreign body aspiration. The histories of these patients were studied to examine the diagnostic value of signs, symptoms and examinations, and to determine the time that passed between aspiration and removal of the foreign body. The sensitivity of the symptoms choking and coughing was fairly high (81 and 78%), but the specificity was poor. The sensitivity of a chest radiograph was 82%, the specificity 44%. The sensitivity of radiographs on inspiration and expiration was 80%, the specificity 55%. The patients had been referred with the initial diagnosis foreign body aspiration (80), pneumonia (34), or subglottic laryngitis (1). In 85 patients a foreign body was identified and extracted. The other 30 patients had respiratory tract infections. The initial diagnosis of foreign body aspiration was correct in 61 out of 85 patients. In these cases, the period between aspiration and extraction of the foreign body was a mean 6 days, compared with 55 days, if the initial diagnosis was pneumonia or sub-glottic laryngitis. We conclude that the diagnosis of foreign body aspiration is too often missed, and that, apart from bronchoscopy, diagnostic tools are of little value.

Wheezing as a sign of foreign-body aspiration in infants and children

Airway obstruction from aspiration of a foreign body should be suspected in all infants and children who have swallowing or respiratory difficulties. If the patient is unable to clear the airway by coughing, the Heimlich maneuver should be attempted. Parents can help to prevent airway obstruction by keeping small objects away from infants and children and by teaching them to chew food thoroughly.

Inhalation of foreign bodies by children: review of experience with 74 cases from Dubai

Seventy four out of 94 cases of bronchoscopy carried out over a five year period are reviewed. The clinical history of choking followed by recurrent spasmodic cough were found to be the most important element in making the diagnosis and proceeding to diagnostic and therapeutic bronchoscopy. Radiology was inferior as a diagnostic aid although radioactive scanning may be helpful in difficult cases.
