Introduction Tracheostomy is the commonest surgical procedure in intensive care units (ICUs). It not only provides stable airway and facilitates pulmonary toilet and ventilator weaning, but also decreases the direct laryngeal injury of endotracheal intubation, and improves patient comfort and daily living activity. Objective The objective of this study is to assess the incidence, indications, timing, complications (early and late), and the outcome of tracheostomy on patients in the intensive care units (ICU) at a university hospital in a developing country...

Tuberculosis (TB) is among the top infectious causes of morbidity and mortality worldwide and is associated with frequent pulmonary damage despite microbiological cure. Patients with treated TB may remain lifelong sufferers of disabling structural and functional sequelae of the disease, which subsequently impair quality of life. Long-term follow-up studies have revealed that many patients with treated pulmonary TB show signs of permanent impairment of their lung function. Impairment is variable in pattern and severity, ranging from none to severe, and shows restrictive, obstructive, or mixed patterns...

We present a case of impassable subglottic stenosis scheduled for tracheal resection and reconstruction managed by establishing a supraglottic airway. Despite careful preoperative evaluation, the stenosis was localized higher than anticipated, rendering conventional intubation impossible. Laryngeal mask bridging to cross-field ventilation was feasible and jet ventilation and cardiopulmonary bypass were available as emergency strategies. Surgery and emergence went uneventful. Perioperative considerations are discussed in this report...

The rare and potentially fatal complication of asystole during direct laryngoscopy is linked to direct vagal stimulation. This case describes asystole in an 85-year-old female who underwent suspension microlaryngoscopy with tracheal dilation for subglottic stenosis. Quick recognition of this rare event with immediate cessation of laryngoscopy resulted in the return of normal sinus rhythm. This incident emphasizes the implications of continued vigilance during laryngoscopy and the importance of communication between the anesthesia and surgical staff to identify and treat this rare complication...

OBJECTIVE: To identify a safe approach to airway management during the endoscopic balloon dilation of subglottic stenosis BACKGROUND: Subglottic stenosis is an abnormal narrowing of the upper airway commonly managed by endoscopic technique performed on an unsecured airway. METHODS: Review of surgical treatment of subglottic stenosis cases by the senior author. TECHNIQUE: Following steroid injection and radial cuts performed either under jet anesthesia or mask ventilation with brief periods of apnea, a small endotracheal tube may be passed beyond the narrowing to permit adjacent balloon dilation with the airway secured...

A 23-day-old infant referred to the neonatal intensive care unit with difficulty breathing and inspiratory stridor increasing with exercise. Medical history included a cardiothoracic surgery for transposition of the great arteries, patent ductus arteriosus, atrial septal defect, and a history of intensive care unit from surgery. Flexible fiberoptic transnasal laryngoscopy revealed subglottic stenosis that was probably caused by prolonged intubation with a higher airway pressure. Computed tomographic scan of the neck showed a tiny stenosis without cartilage deformity and limited in subglottic region...

Surgery is the preferred treatment modality for benign tracheal stenosis. Interventional bronchoscopy is used as a bridge to surgery or in instances when surgery is not feasible or has failed. Stenosis in the subglottic trachea is particularly a treatment challenge, in view of its proximity to the vocal cords. Herein, we describe a patient with complete tracheal stenosis in the subglottic region, which developed after prolonged intubation and mechanical ventilation. The patient developed recurrent stenosis despite multiple surgical and endoscopic procedures...

A 59-year-old man presented to the emergency department with a chief complaint of sore throat after swallowing sodium picosulfate/magnesium citrate powder for bowel preparation, without first dissolving it in water. The initial evaluation showed significant mucosal injury involving the oral cavity, pharynx, and epiglottis. Endotracheal intubation was performed for airway protection in the emergency department, because the mucosal swelling resulted in upper airway compromise. After conservative treatment in the intensive care unit, he underwent tracheostomy because stenosis of the supraglottic and subglottic areas was not relieved...

IMPORTANCE: The etiology of recurrent croup is often anatomic. Currently there is no set criteria for determining who should undergo diagnostic bronchoscopy and which patients are at most risk for having a clinically significant finding. Few studies have addressed these questions. OBJECTIVE: To identify risk factors for clinically significant findings on bronchoscopy in children with recurrent croup and the frequency of bronchoscopy findings in general. DATA SOURCES: PUBMED, Ovid MEDLINE, EMBASE...

It is difficult to directly observe glottal airflow velocity just above the glottis due to sensor size requirements and limited accessibility. We developed a miniature hot-wire probe and flexible fiberscopic high-speed imaging system for human examinations. Simultaneous direct measurement of glottal airflow velocity, subglottal pressure, and vocal fold vibration was achieved in a patient who was treated with a T-tube for tracheal stenosis. Airflow velocity changes at the anterior midline of the vocal folds were synchronized with subglottal pressure changes during each phonation cycle...

OBJECTIVES: Awake Flexible Tracheobronchoscopy (FTB) is an alternative to rigid bronchoscopy or sedated flexible bronchoscopy and allows an awake examination of the tracheobronchial tree. We hypothesized that the ability to perform office bronchoscopy as the need arises during a clinic visit would lead to a high rate of previously undiagnosed and clinically relevant findings. This study reports the rate and nature of such findings for this procedure at our institution. STUDY DESIGN: Retrospective chart review...

Procedure of intubation of children is different to intubation in adults and requires specific considerations. Before intubation management of difficult airway problems should be anticipated. Risk of developing hypoxia is common in children usually due to a reduced apnea tolerance and demands skill of the medical team. Due to soft tissues of the upper airways and the V-shaped epiglottis several laryngoscopes are available. Attention should be kept on a physiological subglottic stenosis, which determines the size of the endotracheal tube...
