A Case of Whistle as Foreign Body in Trachea

Background. Most of foreign body aspiration cases are found in children under the age of fifteen. Pediatric patients often presents with non-food foreign body aspiration, such as toys. The most common clinical manifestation are history of choking following foreign object insertion into the mouth (85%), paroxysmal cough (59%), wheezing (57%) and airway obstruction (5%). Case presentation. Main principle of airway foreign body extraction is to do it immediately in the most optimal condition with slightest possible trauma. Rigid bronchoscopy is a suitable choice for tracheal foreign body extraction. We reported a case of seven years old male with tracheal foreign body presented with history of whistle ingestion five hours prior to admission. This patient was discharged from hospital after third days of rigid bronchoscopy procedure. Conclusion. History of foreign body aspiration in children should be suspected as a tracheobronchial foreign body. Rigid bronchoscopy is preferred to extract foreign bodies present in the trachea. The prognosis for tracheobronchial foreign body aspiration is good if the foreign body is treated early and without complications.

Clinical analysis of tracheobronchial foreign body aspiration in children: a focus on external and intrinsic factors

Background Tracheobronchial foreign body aspiration (TFBA) is a critical disease in children and is extremely dangerous, even life-threatening. The factors affecting the occurrence and prognosis of TFBA are complex. The purpose of this study is to examine the external and intrinsic factors affecting clinical features of TFBA in West China and propose potential effective intervention measures. Methods We retrospectively analyzed the clinical data of pediatric patients diagnosed with TFBA with foreign bodies (FBs) removed by rigid bronchoscopy under general anesthesia at the otolaryngology department from December 2017 to November 2018. The data included age, sex, clinical symptoms, type and location of FB, guardians, prehospital duration and residence of these pediatric patients. Results The ratio of males (72) to females (53) was 1.4:1. Children aged from 1 to 3 years accounted for 76% (95/125) of patients. Cough, continuous fever and dyspnea were the primary symptoms. The right primary bronchus was the most common location of FB detection by rigid bronchoscopy (67 cases, 53.6%). Organic FBs were most common in our study. Guardians of patients significantly differed in the rural (parents 16, grandparents 31) and urban (parents 52, grandparents 26) groups (χ2 = 12.583, p = 0.000). More children in the rural group than in the urban group had a treatment delay longer than 72 h. More children in the group with no history of FB aspiration (12, 25%) than in the group with prior FB aspiration had a treatment delay longer than 72 h. Conclusion Pediatric TFBA is a common emergency in otolaryngology. Age, sex, tracheobronchial anatomy and other physiological elements were defined as intrinsic factors, while guardians, residence, FB species and prehospital time were defined as external factors of TFBA. External and intrinsic factors both influence the occurrence and progression of TFBA. It is extremely important to take effective measures to control external factors, which can decrease morbidity and mortality.

Challenges in Management of Tracheobronchial Foreign Bodies with Delayed Presentation: An Institutional Experience

Introduction Airway foreign bodies are emergencies involving multidisciplinary departments like Pediatrics, Aneasthesiology and Otorhinolaryngology. It is always a challenge to diagnose and manage patients who present late to our emergencies. Objective In the present study, we aim to analyze the various challenges faced during the management of tracheobronchial foreign bodies with delayed presentation. Methods A retrospective hospital record-based analysis of patients who presented to us with tracheobronchial foreign bodies from January 2017 to February 2020 was performed. All patients until the age of 16 years old were included in the present study. We assessed the demographics, preoperative, intraoperative and postoperative data of the patients. Results Seventeen patients were analyzed in the study. Among these, 44.4% of the patients had delayed presentation (> 1 month). The majority of the patients had an organic foreign body (Supari or betel nut). All patients underwent rigid bronchoscopy, followed by optical forceps-assisted removal of the foreign body. A total of 82% of the patients had granulations around the foreign body. Conclusion Management of delayed presentation tracheobronchial foreign body is a big challenge for Otorhinolaryngologists. The key factors for preventing complications in the definitive management of tracheobronchial foreign bodies are preoperative planning, multi-discipline teamwork, surgeon expertise and technique.

Risk factors for lower respiratory tract infection associated with tracheobronchial foreign body aspiration in children

Background: Tracheobronchial foreign body aspiration (TFBA) is a major cause of death in children. There are few reports about lower respiratory tract infection (LRTI) caused by TFBA. This study collected the TFBA in our hospital to analyze the LRTI and to determine its risk factors. Methods: A total of 194 children who were performed TFBA extraction in The Children’s Hospital of Zhejiang University School of Medicine between June 2019 and April 2020 were enrolled. The clinical data, cervicothoracic CT and operation records were collected. Chi-square test, rank sum test and multivariate logistics regression analysis were applied. Results: The incidence of LRTI was 46.6%, 68.6% and 68.6% respectively when retention time was within 24 hours, 1 week and more than 1 week. Cervicothoracic CT showed embedding site in and above trachea in 24 cases, in main bronchus in 134 cases, in segmental bronchus and below in 36 cases. Cervicothoracic CT showed no obvious abnormality in 60 cases, obstructive emphysema or atelectasis in 77 cases, obstructive pneumonia in 50 cases, and the rest in 7 cases. Cervicothoracic CT diagnosis and retention time of TFBA were different between LRTI group and non-LRTI group in univariate analysis. There was a correlation between the retention time of TFBA and LRTI in multivariate logistics regression analysis. Conclusionss: The incidence of LRTI caused by TFBA is high. There was no difference in the incidence of LRTI between organic and inorganic TFBA. The retention time of TFBA is an independent risk factor for LRTI.

Anesthesia during rigid bronchoscopy for tracheobronchial foreign body removal in children：A Systematic Review and Meta-analysis of Comparative Studies

Background: There is no consensus regarding the optimal anesthetic approach to rigid bronchoscopy in children suffering from tracheobronchial FBA. We performed this meta-analysis to assess the efficacy and safety of the different anesthesia agents and ventilation modes for tracheobronchial foreign body removal via rigid bronchoscopy in young children. Methods: A systematic search of three major databases for all relevant articles. A meta-analysis was performed to analyze the data. Results: Four trials for evaluating different anesthetics and six trials for evaluating two kinds of ventilation modes were found. Compared with the sevoflurane-based volatile anesthesia group , the rate of perioperative complications included hypoxemia (OR, 2.07; 95% CI, 1.38–3.11; P=0.0004; I2 = 0%), apnea (OR, 2.74; 95% CI, 1.11–6.78; P = 0.03; I2 = 60%), laryngospasm (OR, 2.89; 95% CI, 1.67–4.98; P=0.0001; I2 = 0%), cough/bucking (OR, 2.93; 95% CI, 1.86–4.63; P<0.00001; I2 = 0%), and body movement (OR, 3.51; 95% CI, 2.03–6.09; P<0.00001; I2 = 0%) were significantly increased in the propofol-based total intravenous anesthesia and the duration of operation were longer in the Group Prop. Compared with the control ventilation group , the incidences of laryngospasm (OR, 0.16; 95% CI, 0.05–0.56; P=0.004; I2 = 54%), apnea (OR, 0.21; 95% CI, 0.09–0.50; P=0.0004; I2 = 0%), and cough/bucking (OR, 0.03; 95% CI, 0.01–0.10; P<0.00001; I2 = 41%) increased in the spontaneous ventilation group and the duration of operationand emergence from anesthesia significantly prolonged in the Group SV. Conclusions: Our meta-analysis suggests that sevoflurane-based volatile anesthesia was superior to propofol-based total intravenous anesthesia for the management of foreign body aspiration in children. There is still no strong evidence indicated that one ventilation technique was superio

Our Anesthesia Experiences in the Tracheobronchial Foreign Body Aspirations of Pediatric Patients During Rigid Bronchoscopy

Objective: Bronchoscopy is the gold standard in the diagnosis and treatment of tracheobronchial foreign body aspiration (TBFBA) in children. Rigid bronchoscopy (RB) under general anesthesia is generally preferred in children. In this article, our anesthesia experiences during rigid bronchoscopy performed for tracheobronchial foreign body aspiration and removal of foreign bodies in children are shared. Methods: The medical records of all patients aged between 0-18 years who underwent RB under general anesthesia due to suspicion of TBFBA between January 1, 2014 and December 31, 2018 were retrospectively analyzed. Results: TBFBA was more common in boys and organic foreign body aspiration was significantly higher in patients between 13-36 months of age. Patients most frequently presented with cough and wheezing. Most of them were operated between 8 am and 4 pm. TFBs were localized in the right and left main bronchi at a similar rate. Anesthesia induction was usually achieved with iv. propofol, total intravenous anesthesia and sevoflurane inhalation was administered for maintenance of anesthesia. Except for proximally located TBFBs, intermediate-or short-acting muscle relaxants were applied to most of the cases depending on the duration of the procedure. Three patients were intubated postoperatively and transferred to intensive care unit. Respiratory distress responded to medical treatment in 25 patients. No cardiac arrest or death occurred during the procedure. Conclusion: RB and anesthesia procedure for TBYCA requires experience. There is no clear recommendation about premedication, the use of muscle relaxants should be evaluated according to the localization of TBYC. In anesthesia management, intravenous or inhalation anesthetics can be used.

ROLE OF RIGID BRONCHOSCOPY IN MANAGEMENT OF TRACHEOBRONCHIAL FOREIGN BODY ASPIRATION

Objective: To determine the role of Rigid Bronchoscopy in Management of Tracheobronchial Foreign Body Aspiration. Material and Methods: This study was conducted in otolaryngology department, Khyber teaching hospital, Peshawar of one year duration from January 2018 to December 2019. Total 90 Patients of age 4 months to 14 years on clinical suspicion of foreign body bronchus were included, while patients with history of bronchial asthma, pulmonary tuberculosis and radio opaque foreign body bronchus were excluded. Results: Total number of patients was 90 in which male patients were 60 (66.67 %) and female patients were 30 (33.33 %), patients with foreign body bronchus were 80 (88.89%). Male patients with foreign body bronchus was 53 (58.89%) and female 27 (30.00%). In age range from 4 months to 3 years, 35(39%) Patients underwent bronchoscopy in which foreign body bronchus retrieved in 30(37.5%) patients. Conclusion: Patients with history of repeated chest infection, relieved by medicines for some time should not be over look, as vegetative foreign body bronchus are radiolucent and patients usually present late in respiratory compromised state, the clinician must urge, for prompt treatment as rigid bronchoscopy.
