ABSTRACT
Objective To explore the clinical characteristics of bronchial foreign bodies in children. Method The clinical data of 147 children with exogenous bronchial foreign body admitted between 2014 and 2016 were retrospectively analyzed, and the applications of rigid bronchoscopy and flexible bronchoscopy for foreign body extraction were compared. Results All 147 cases were diagnosed with bronchial foreign bodies by chest CT, chest X-ray or respiratory endoscopy. In these cases (104 boys and 43 girls) , 87.8％ of whom were aged 1-3 years, the most common types of bronchial foreign body were nuts. The common complications were bronchial mucosal granulation tissue hyperplasia (88 cases, 59.86％) , pneumonia (56 cases, 38.1％) , atelectasis (15 cases, 10.2％) , respiratory failure (14 cases, 9.52％) and bronchiectasis (4 cases, 2.72％) respectively. The foreign bodies were removed by soft bronchoscopy in 106 cases which were successfully removed at one time in 100 cases. Respiratory endoscopy was undergone in 141 cases to remove foreign bodies, and flexible bronchoscope was applied in 106 (72.11％) cases and foreign bodies were successfully removed in first attempt in 100 cases (94.34％) . Rigid bronchoscope was used in 35 cases (23.81％) and foreign bodies were successfully removed in first attempt in 28 cases (80.0％) . Conclusion The majority of children with bronchial foreign body are male. Both flexible and rigid bronchoscopes can remove exogenous foreign bodies in the lower respiratory tract.
ABSTRACT
Objective To investigate the lung function data from infants of bronchial foreign body and bronchiolitis,and to explore the diagnostic values of functional residual capacity plethysmograph(FRCp) in the two diseases.Methods During January 2016 to January 2018,forty-six infants diagnosed with bronchial foreign body were selected as subjects.As well as 50 children diagnosed with bronchiolitis were selected as control group.All of the children had completed tidal breath pulmonary function test,lung compliance measurements using interrupter technique and plethysmographic measurements of FRCp.The differential diagnostic values of FRCp for the two diseases were analyzed with the receiver operating characteristic curve.Results In the bronchial foreign body group,respiratory rate (RR) was 31 ± 7 times per minute,VT/kg was 7.7 ± 1.5ml/kg,TPTEF/TE was 24.3 (9.4％,VPEF/VE was 26.1％ ± 7.6％,Ti/Te was 0.66 ± 0.10,and FRCp was 280.6(208.4 ～ 396.1) ml.In bronchial foreign body infants,FRCp was obviously higher than that in control group (P ＜0.01),RR was higher than that in control group(P ＜0.05).There were no significant differences found in other indicators between the two groups.The optimal cut-off value of FRCp was 202.95 ml for the differentiation between the two groups,with a sensitivity of 85％ and a specificity of 54％.Conclusion Most bronchial foreign body infants have obstructive ventilation dysfunction with elevated FRCp.FRCp in bronchial foreign body infants were obviously higher than that in bronchiolitis infants.Measurements of FRCp may be useful in the differential diagnosis of infant bronchial foreign body and bronchiolitis.
ABSTRACT
Objective To explore the effectiveness and safety of fiberbronchoscope combined with cryotherapeatic equipment in treatment of bronchial foreign body in children.Methods 72 children with bronchial foreign body received fiberbronchoscope combined with cryotherapeatic equipment, then the complications were observed during and after the operation.Results Bronchial foreign bodies were successfully removed in all the patients. Among the 72 cases, transient hypoxia was the most common complication during the operation which happened in 37 cases and most occurred in the small age group, and decreased with the age increasing; cough or worsening of cough was the most common complication after the operation which happened in 20 cases; No serious complications were found during the follow-up.Conclusion Although it has some complications when bronchial foreign body received the fiberbronchoscope combined with cryotherapeatic equipment, but the operation time is short, and the complication is mild. It has great application value and security.
ABSTRACT
Introducción: Los cuerpos extraños en vía aérea (CEVA) continúan siendo un desafío clínico que genera un espectro de presentaciones, desde mínima sintomatología a compromiso respiratorio, falla respiratoria e incluso muerte. Objetivos: Describir y analizar las características epidemiológicas y clínicas de los pacientes con sospecha de CEVA evaluados en el Hospital Guillermo Grant Benavente. Material y método: Estudio retrospectivo y descriptivo de pacientes con diagnóstico de CEVA admitidos en nuestro servicio de urgencia, entre los años 1997 y 2015. Se analizaron diferentes variables, especialmente en relación a síntomas, signos, hallazgos radiológicos, complicaciones, tratamiento y resultados. Resultados: Se encontraron 117 broncoscopías rígidas, confirmándose CEVA en 94 (80,4%). La mayoría niños entre 1-3 años. Hubo más de una consulta previa al diagnóstico en el 29,8%, siendo la mayoría de las consultas precoces. La mayoría informó síndrome de penetración, pero esto no hizo la diferencia en el diagnóstico. El 80,9% de los casos confirmados tuvo alguna alteración radiológica (excluyendo cuerpos radio-opacos) (p <0,05). Se ubicó en árbol bronquial derecho mayormente, siendo de una naturaleza variada. Se extrajo en el primer intento sin incidentes el 91,5%. No hubo complicaciones reportadas en relación a las extracciones. Conclusiones: Un cuerpo extraño en el tracto respiratorio es una emergencia quirúrgica, pudiendo ser incluso fatal. Un alto índice de sospecha es fundamental para evitar complicaciones.
Introduction: Airway Foreign bodies (AFB) remain a clinical challenge, generate a spectrum of presentations, from minimal symptoms to respiratory distress, respiratory failure and even death. Aim: To describe and analyze the epidemiological and clinical characteristics of patients with suspected AFB. Material and methods: A retrospective and descriptive study of patients diagnosed with AFB admitted to our Emergency Service between 1997 and 2015. Different variables were analyzed, especiallytheir symptoms, signs, radiologic findings, complications, treatment and outcomes. Results: 117 rigid bronchoscopies associated with suspected AFB were found. The diagnosis was confirmed in 94 cases (80.4%). Most ofthem were children between 1-3 years. There was more than one consultation before the diagnosis in 29.85. Most of the patients reported penetration syndrome, but this made no difference on diagnosis. 80.9% ofthe confirmed cases had some radiological alteration (excluding radiopaque bodies) (p <0.05). Most of the cases were found in the right bronchial tree and were of a varied nature. They were extracted in the first attempt without incidents in 91.5% of the cases. There were no reported complications regarding extractions. Conclusions: A foreign body in the respiratory tract is a surgical emergency, and may even be fatal. A high index of suspicion is essential to avoid complications.

ABSTRACT
Objectives: To evaluate the utility of measuring lung radiodensity from chest X-ray for the diagnosis of foreign body aspiration Methods: Records of 59 children with foreign body aspiration were retrospectively reviewed. Lung radiodensity and radiodensity ratio (right/left lung radio density) before and after foreign body removal were measured. Radiodensity was calculated as the relative score compared with the tenth thoracic vertebra body (100 points) and the background (0 point). The change of radiodensity ratio (difference in radiodensity ratio of the second X-ray from that of first X-ray) was compared between 22 patients (foreign body group) and 22 normal subjects (control group). Results: In the group of foreign body in the left bronchus, the mean (SD) radiodensity of the left lung [53.5 (12.8)] was lower than that of the right lung [60.8 (7.7), P<0.01] and it increased after foreign body removal [60.0 (6.9), P=0.02]. The radiodensity ratio decreased from 1.20 (0.30) to 0.96 (0.09) (P<0.01) after foreign body removal. In the group with a foreign body in the right bronchus, the radiodensity of the right lung [51.8 (12.8)] was lower than that of left lung [62.0 (11.7), P=0.03], and it also increased after foreign body removal [58.4 (9.6), P=0.03]. The change of radiodensity ratio in the foreign body group [15.7 (17.8)%] was higher than the control group [5.4 (4.3)%, P=0.01] and the cutoff value was 7.5%. Conclusion: Radiodensity from chest X-ray could be a useful tool for diagnosing foreign body aspiration in children.
ABSTRACT
Objective To investigate the advantages of pediatric electronic fiber bronchoscope ( FBO) in the infant bronchial foreign body,discuss the clinical features of infant bronchial foreign body,lung imaging characteristics and the kinds of microscopically position,the change of airway mucosa after stimulation by for-eign body under local anesthesia in 30 cases of infant bronchial foreign body. Methods Thirty cases,aged 0 to 3 years,were collected from September to December,2014. All of them were with foreign bodies examined by FBO in pediatric bronchoscopy room in Shengjing Hospital of China Medical University. Results In all infants, 6 cases (20. 0%) without history of inhaled foreign bodies and 24 cases (80. 0%) with a record history of in-haled. In the aspects of signs:normal breath sounds with a history of no choking cough in children were 2 cases (6. 7%) ,wheezing sounds were 3 patients (10. 0%) and weakened side breath sound was 1 case (3. 3%);with a history of choking cough in children,6 cases(20. 0%) with normal breath sounds,12 cases(40. 0%) with wheez-ing,6 cases(20. 0%) with lateral breath sounds less. Lung imaging characteristics was lack of specific perform-ance:only a case of all(n=30)show foreign body directly. Otherwise,other 29 cases had no specificity. Lung em-physema in 13 cases (43. 3%) is the main characteristic,while normal imaging findings in 2 cases (6. 7%). For-eign bodies in 19 cases were in the left lung (63. 4%) and 21 cases(70. 0%) of foreign body stimulated granula-tion inside airway,necrosis sputum bolt in distal obstruction of airway occured in 5 cases (16. 7%). Inhalled time of foreign body in airway was 4. 5 [2. 8,12. 5] day and inhalled time of foreign body in airway correlation coefficient with granulation hyperplasia(r=0. 688,P=0. 000),there was a significant correlation. Main adverse reaction was low oxygen in 6 cases (16. 7%). Conclusion The diagnostic accuracy of FBO under local anesthesia on children is high-er than other methods,and the FBO bronchial foreign bodies under local anesthesia is a safe and effective method.
ABSTRACT
Objective Comparing the effect of different anesthetic inductions in pediatric pa-tients undergoing bronchial foreign body removal.Methods Thirty pediatric patients,aged 9-58 months,undergoing emergency bronchial foreign body removal,were randomly into 3 groups (n=10 each):group sevoflurane (group S),group propofol (group P),and group ketamine (group K).Pa-tients in group S were inducted with sevoflurane 8% inhalation,group P with propofol 2.5 mg/kg in-travenous injection,group K with ketamine 5 mg/kg intramuscular injection.Three groups of pa-tients breathed spontaneously during operative period and received topical anesthesia of lidocaine be-fore the placement of rigid bronchoscopy.Combination of intravenous target-controlled infusion of propofol (target plasma concentration of 3-3.5 μg/ml)and remifentanil (target plasma concentration of 2-3 ng/ml)was used for maintenance of anesthesia.The rigid bronchoscopy was inserted after pre-oxygenation for 3 min.Rigid bronchoscopy was performed and the placement time,the first place-ment successfully rate,hypoxemia and side effects as well as postoperative awaking time were recor-ded.Results The first placement successfully rate,group S 90%,group P 70%,group K 40%,with significant difference among three groups (P<0.05).The incidence of side effects were not signifi-cant difference in three groups;In group S and group P,the placement time and the anesthesia awa-king time was significant shorter than that in group K (P<0.05).Conclusion Compared with propo-fol intravenous induction and ketamine intramuscular induction,the high concentration sevoflurane in-duction can provide faster induction,shorter waking time,and reduceside effects in childen undergo-ing bronchial foreign body removal.
ABSTRACT
Foreign body inhalation is a clinical emergency requiring prompt action to ensure speedy recovery and minimize the complications. This is common in children rather than in adults. We hereby report a case of a neglected foreign body which remained in the bronchus of a child for years before the diagnosis was made and appropriate treatment was given.
ABSTRACT
Foreign body in the airway could be a life-threatening risk, especially for young pediatric patients. A 6-day old male patient with foreign body, which was located deep in the right main bronchus was being admitted. Although we tried three times to remove it with rigid bronchoscopic forceps under the general anesthesia, we failed. Before switching to surgical treatment, we changed the Trendelenburg position and tapped his back several times in order to alter the foreign body toward the forcep. Finally we were able to catch and extract the foreign body successfully. We suggest that back percussion with the Trendelenburg position is a useful solution to remove a foreign body within a deep airway.

PURPOSE: The purpose of this study was to investigate the diagnostic value of spiral computed tomography (CT) using contiguous slices with partially thin sections around the hilar level in the bronchial foreign bodies of children with a vague history of aspiration. METHODS: Fourteen children were identified to be examined with spiral CT due to obscure histories of aspiration episodes. A retrospective analysis of the medical records provided information concerning the clinical and radiological findings. RESULTS: Of the 14 patients examined with spiral CT, there were no significant differences among the clinical and initial radiological findings with the exception of gender distribution. However, the spiral CT scans allowed accurate discrimination among patients with a vague history of aspiration episodes, in which seven were identified with bronchial foreign body aspiration and seven with bronchiolitis, asthma, tracheobronchitis and/or pneumonia. CONCLUSION: We found that spiral CT using contiguous slices with partially thin sections around the hilar level are a useful non-invasive method in the early diagnosis of bronchial foreign bodies in children with a vague history of aspiration.

We report a premature neonate who suffered from bronchial foreign body. The neonate was delivered at 34 weeks of gestational age, 1,850 g of birth weight, through Cesarean section. After birth the baby showed respiratory distress and received surfactant therapy on the first hospital day. After extubation on the 10th hospital day, the baby experienced 2 episodes of pneumonia in the right upper lung field. On the 27th day after birth, a chest X-ray revealed a feeding tube-shaped foreign body which was located from right main bronchus to trachea, about 4.5 cm long and 2.0 mm wide. The patient was too small to remove the foreign body by even the smallest-diametered fibroptic bronchoscopy. We rotated the baby to a nearly 90 degree head-down position and percussed on the back. After confirming the movement of foreign body in to the trachea, we intubated 3.0 Fr. endotracheal tube under fluoroscopic observation. We found that a tip of foreign body was inserted into the ET tube innerside. We sucked out the foreign body by mechanical suction with central-holed rubber suction tip. Forced expiration with cough reflex and intubation with mechanical suction allowed for the successful removal of the foreign body.

Bronchial foreign body is not a rare disease in children and it is urgently necessary to remove this foreign body from the airway to relive life or to prevent further damages and complications. But the innate small size of airways in infants makes it difficult to access by interventional methods such as intubation or bronchoscopy and etc. Laryngeal mask airway is a new way of method of airway management which is relatively recently introduced into medical practice. It gives way to access to airways without reducing the size of airway or incresing airway pressure during procedure through it and have many other advantages compared to the previous traditional endotracheal intubation, especially in infants. We successfully removed a case of bronchial foreign body, peanut, via laryngeal mask airway during fiberoptic bronchoscopy and by this method we can avoid the unnecessary tracheostomy in this 1 year old infant.
