OBJECTIVES: To determine the clinical presentations and management of patients with acute laryngeal obstruction. [ncbi.nlm.nih.gov]

• Cough

  The hemorrhagic lesions appeared to be induced by coughing due to bronchitis for which the penicillin was given. [ncbi.nlm.nih.gov]

  […] experience the following symptoms: Shortness of breath Chest and/or throat tightness Feeling they are "breathing through a straw" Stridor/wheezing Difficulty with inhalation and/or exhalation Frequent throat clearing Intermittent hoarseness Chronic cough [nationaljewish.org]

  The result is symptoms such as: Coughing with asthma Tightening of the chest Wheezing Unusual fatigue while exercising Shortness of breath when exercising The other interesting condition that turned up in my research is Exercise-Induced Laryngeal Obstruction [runningwithfaith.com]

  20 to 30 minutes after stopping exercise or with a bronchodilator Spontaneous resolution within minutes of stopping exercise Chest tightness Throat tightness Difficulty during expiration Visible tension in sternocleidomastoid and/or scalenes Wheeze, cough [healio.com]

• Dyspnea

  But slight inspiratory dyspnea and stridor may occur during crying or on exertion 5 Laryngeal obstruction classification: Ⅱ slight inspiratory dyspnea during quiet respiration, and exaggeration on exertion. [slideplayer.com]

  Exercise-induced laryngeal obstruction is a cause of exercise-induced dyspnea. [healio.com]

  KEYWORDS: Athlete; dyspnea; exercise; larynx; swimming [ncbi.nlm.nih.gov]

• Hoarseness

  A boy with junctional epidermolysis bullosa died from acute laryngeal obstruction at the age of 29 months, having been hoarse since early infancy. [ncbi.nlm.nih.gov]

  Although their usual presenting symptom is hoarseness, acute airway obstruction from laryngeal polyps is uncommon. [academic.oup.com]

  […] with VCD and EILO may experience the following symptoms: Shortness of breath Chest and/or throat tightness Feeling they are "breathing through a straw" Stridor/wheezing Difficulty with inhalation and/or exhalation Frequent throat clearing Intermittent hoarseness [nationaljewish.org]

• Pursed-Lip Breathing

  Pursed lip breathing slows respiration overall (12 to 16 breaths per minute). [healio.com]

• Gagging

  Cannot be used in awake patients, as it causes them to gag and potentially vomit. [learnpicu.com]

  There may also be paroxysmal coughing, gagging or choking, hoarseness, wheezing, tachycardia and other signs of respiratory distress. Patients are usually anxious and distressed. Narrowing above the larynx causes stridor. [patient.info]

  […] relieved within 2-5 minutes of the onset partial UAO: stable, or progressive deterioration signs and symptoms may be mild but as they worsen include coughing, inspiratory stridor, crowing or noisy respiration, dysphonia, aphonia, choking, drooling and gagging [aic.cuhk.edu.hk]

• Pachyonychia

  A 2-year-old girl presented with typical clinical features of pachyonychia congenita shortly after birth. [ncbi.nlm.nih.gov]

• Distractibility

  In addition, one must also reinforce the tenets of motor learning in that these skills are taught and practiced with increasing levels of distraction or stress. [healio.com]

  Any method, such as speech therapy, that focuses attention away from the larynx ( e.g. nasal breathing, diaphragmatic breathing) may have an effect through distracting the attention away from breathing problems and refocusing attention to a specific task [erj.ersjournals.com]

• Impulsivity

  Health care providers should advocate for objective testing, including bronchoprovocation, spirometry, and/or impulse oscillometry to identify exercise-induced laryngeal obstruction. [healio.com]

  Vocal cord dysfunction as demonstrated by impulse oscillometry. J Allergy Clin Immunol Pract (2013) 1(4):387–93. doi:10.1016/j.jaip.2013.05.005 PubMed Abstract CrossRef Full Text Google Scholar 4. [journal.frontiersin.org]

• Generalized Tonic-Clonic Seizure

  We present the case of a 78-year-old woman who was treated with phenytoin for generalized tonic-clonic seizures for 4 months and who subsequently developed lingual hyperplasia that caused laryngeal obstruction eventually requiring a tracheotomy. [ncbi.nlm.nih.gov]

RESULTS: Of 88 athletes who completed a full workup, 31 (35.2%) had EILO and 38 (43.2%) had a positive bronchoprovocation or bronchodilator reversibility test. [ncbi.nlm.nih.gov]

• Ventricular Hypertrophy

  In addition, right ventricular hypertrophy and pulmonary artery atherosclerosis were found. [peertechz.com]

In case of severe supraglottic collapse and pronounced symptoms during strenuous exertion, surgical treatment (supraglottoplasty) has been suggested. [ncbi.nlm.nih.gov]

Finally circulatory collapse may occur or may die of asphyxia or cardiac failure. 8 Laryngeal obstruction Treatment Ⅰ ：etiological treatment, antibiotics and corticosteroid. 9 Laryngeal obstruction Treatment Ⅱ ：etiological treatment. in case of tumors [slideplayer.com]

The patients reported a better ability to breathe while exercising, after surgical treatment, as revealed by VAS scores. [bora.uib.no]

Overall prognosis is considered considered generally poor 6. tracheal atresia Promoted articles (advertising) [radiopaedia.org]

The prognosis is poor with squamous cell carcinoma of the trachea, which carries a 5-year survival of approximately 40% when resectable and 7% when unresectable. [clinicaladvisor.com]

[…] especially when being prepared for children Consume food slowly and fully chew food before swallowing, which is an effective preventative method Closely watch very young children while they play with toys and small play items (toy parts) What is the Prognosis [dovemed.com]

Prognosis of EILO It has been suggested that laryngeal growth and maturation during puberty should make the larynx more robust to inward forces at high minute ventilation [ 61 ]. [link.springer.com]

CONCLUSIONS: In athletes with unexplained respiratory symptoms, EILO is an important differential diagnosis not discerned from other etiologies by clinical features. [ncbi.nlm.nih.gov]

Finally circulatory collapse may occur or may die of asphyxia or cardiac failure. 8 Laryngeal obstruction Treatment Ⅰ ：etiological treatment, antibiotics and corticosteroid. 9 Laryngeal obstruction Treatment Ⅱ ：etiological treatment. in case of tumors [slideplayer.com]

The etiology is unknown, although sporadic, genetic (3) and vascular causes (4) have all been proposed. [fetalultrasound.com]

This review of the literature provides an overview of the current understanding of the definition, epidemiology, diagnosis and management of EILO. [ncbi.nlm.nih.gov]

Epidemiology The reported epidemiology of ILO varies considerably, depending on the diagnostic criteria employed ( table 2 ). [erj.ersjournals.com]

Biphasic stridor suggests subglottic or glottic obstruction. [ 1 ] Epidemiology The detailed epidemiology of stridor depends on the cause, but it is worth noting the following patterns of disease: Stridor is common in younger children with smaller airways [patient.info]

Specifically, our understanding of the aetiology and pathophysiology remain poor and despite considerable technological advances, robust, validated, diagnostic and treatment algorithms are yet to be established. [erj.ersjournals.com]

See Figure 2 for a comparison of what 1 mm of circumferential edema does in terms of airway resistance to an infant and an adult Pathophysiology Upper airway obstruction can occur for a variety of causes, but fundamentally, leads to increased airway resistance [learnpicu.com]

Gavin Joynt Pathophysiology - obstruction is likely to occur at sites of anatomic narrowing such as the hypopharynx at the base of the tongue and the false and true vocal cords at the laryngeal opening. - sites of airway obstruction are referred to as [aic.cuhk.edu.hk]

Palliative interventions for patients with chronic upper airway obstruction include: balloon dilatation airway stenting laser therapy electrocautery and argon plasma coagulation cryotherapy nocturnal, noninvasive, positive-pressure ventilation Pathophysiology [clinicaladvisor.com]

The primary physician must know when and where to send these children in order to prevent the fatalities so frequent in previous years. [ncbi.nlm.nih.gov]

Airway secretions, edema, and downward folding of the epiglottis cause complete laryngeal obstruction, preventing endotracheal intubation. [anatomicaljustice.com]

The American Thoracic Society and the European Respiratory Society define refractory asthma as asthma that requires treatment with high-dose inhaled corticosteroids (ICS) plus a second controller and/or systemic corticosteroids to prevent it from becoming [figshare.com]

Prompt evaluation and management of suspected UAO may prevent subsequent complications including cardiac arrest, anoxic brain injury, and negative pressure pulmonary edema. [accessmedicine.mhmedical.com]

There are no definitive methods to prevent Acute Upper Airway Obstruction. However, proper precautions may be taken to reduce risks. [dovemed.com]
