Prevention and Treatment of Laryngospasm in the Pediatric Patient: A Literature Review.

AANA J 2019 Apr;87(2):145-151

is on faculty in the nurse anesthesia program at Western Carolina University, Asheville, North Carolina.

Laryngospasm is an exaggeration of a protective reflex that prevents aspiration of foreign objects into the lower airway (eg, during swallowing). This results in complete or partial closure of the glottis, and impedance or total obstruction of airflow to the trachea and lungs. Often, the resulting hypoxia will by itself break a laryngospasm; however, if the spasm continues without relief, it can lead to pulmonary edema, cardiac dysrhythmias, cardiac arrest, and ultimately death.

Section of Allergy, Division of Pulmonary, Allergy and Critical Care Medicine, University of Pittsburgh Medical Center, Pittsburgh, PA, USA. Electronic address:

Vocal cord dysfunction (VCD) is an upper airway disorder characterized by exaggerated and transient glottic constriction causing respiratory and laryngeal symptoms. Although the origin of VCD symptoms is in the upper airway, it is frequently misdiagnosed as asthma resulting in significant morbidity. VCD can coexist with asthma or mimic allergic conditions affecting the upper airway. Read More

A Trigger Reduction Approach to Treatment of Paradoxical Vocal Fold Motion Disorder in the Pediatric Population.

J Voice 2019 Sep 16. Epub 2019 Sep 16.

Department of Otolaryngology, New York Medical College, School of Medicine, Valhalla, New York.

Objectives: Paradoxical vocal fold motion disorder (PVFMD), or induced laryngeal obstruction (ILO), is a clinical phenomenon characterized by inappropriate adduction of the true vocal folds during inspiration. The resultant episodes of acute respiratory distress marked by exercise-induced cough, inspiratory stridor, throat tightness, and shortness of breath are often misattributed to asthma despite normal pulmonary function testing results. Although the pathogenesis of the disease remains unclear, the etiology is likely multifactorial with an inflammatory, neurological, and psychiatric basis. Read More

Trauma-informed care improves management of paradoxical vocal fold movement patients.

Laryngoscope 2020 Jun 11;130(6):1508-1513. Epub 2019 Sep 11.

Department of Otolaryngology-Head & Neck Surgery, Chicago Institute for Voice Care, University of Illinois at Chicago, Chicago, Illinois.

Objectives: Vocal cord dysfunction (VCD) has been used by clinicians, primarily pulmonologists, to describe a variety of conditions in which the regulation and coordination of vocal fold movements are part of the explanation of cough or difficulty breathing, mainly paradoxical vocal fold motion disorder (PVFM). Prior studies show an intersection of mental health issues, primarily anxiety, and PVFM. We began incorporating mental health screening tools using the Life Events Checklist-5 (LEC-5) and the Posttraumatic Stress Disorder (PTSD) Checklist for Civilians (PCL-C) to assess symptomatology that may be related to traumatic life events.

Environmental Exposures and Asthma in Active Duty Service Members.

Curr Allergy Asthma Rep 2019 09 4;19(9):43. Epub 2019 Sep 4.

Division of Allergy/Immunology, Naval Medical Center Portsmouth, 620 John Paul Jones Circle, Portsmouth, VA, 23708, USA.

Purpose Of Review: Reports of respiratory symptoms, including asthma and hyper-reactive airway disease, have been more numerous in the media and medical literature since active duty service members (SM) began to support campaigns in South West Asia (SWA). Numerous environmental exposures have been reported and this review assesses the available evidence surrounding exposures, confounding conditions, and attempts to develop screening mechanisms.

Recent Findings: While particulate matter exposures and particularly exposure to burn pits have garnered much attention, a 2010 Armed Forces Health Surveillance Center report and 2011 Institute of Medicine publication did not identify a link between exposure to particulate matter with SM respiratory disease.

Buteyko Breathing Technique for Exertion-Induced Paradoxical Vocal Fold Motion (EI-PVFM).

J Voice 2019 Aug 12. Epub 2019 Aug 12.

Department of Communication Sciences and Disorders, University of Delaware, Newark, Delaware.

Purpose: The primary purpose of the current study was to determine the usefulness of Buteyko breathing technique (BBT) in reducing dyspnea in patients with one form of Paradoxical Vocal Fold Motion (PVFM), exertion-induced PVFM (EI-PVFM), concomitant with hyperventilation. The secondary purpose was to determine whether BBT had an effect on physiological markers of hyperventilation, as speculated by BBT theory: respiratory tidal minute volume (RTMV), end-tidal carbon dioxide (ETCO), and resting heart rate (HR).

Methods: Using a within-subjects, repeated measures group design, 12 participants with EI-PVFM and hyperventilation underwent 12 weeks of BBT, following an initial no-treatment control condition. Read More

Int J Pediatr Otorhinolaryngol 2019 Oct 18;125:199-200. Epub 2019 Jul 18.

Northwestern University Feinberg School of Medicine, Department of Otolaryngology - Head and Neck Surgery, 675 N St Clair Ct Suite 15-200, Chicago, IL, 60611, USA; Ann & Robert H. Lurie Children's Hospital of Chicago, Division of Otolaryngology - Head and Neck Surgery, 225 E. Chicago Ave., Chicago, IL, 60611, USA. Electronic address:

We present a unique case of intermittent paradoxical vocal fold motion (PVFM) as the presenting symptom of a rare underlying neuromuscular disorder in a neonate. Paramyotonia congenita (PC) is an autosomal dominant condition that typically presents in infancy with myotonic episodes affecting the skeletal muscles. Our patient developed intermittent episodes of stridor quickly progressing to apnea shortly after birth that were marked by PVFM on laryngoscopy, ultimately leading to the diagnosis of a previously unrecognized mutation in SCN4A, the gene responsible for PC.

Negative-pressure pulmonary edema (NPPE) is acute-onset bilateral pulmonary interstitial edema. This condition can be caused by significant negative intrathoracic pressure generated by large inspiratory effort against acute upper airway obstruction. Postoperative NPPE is rare but potentially life-threatening if not recognized and treated promptly. Read More
