Laryngospasm
Laryngospasm
Laryngospasm (/ˌlærɪŋˈɡoʊˌspæzəm/) is a sudden, involuntary muscular contraction of the laryngeal cords. The condition typically occurs in response to a stimulus such as smoke, dust or a foreign body in the throat.
Etymology
The term "laryngospasm" is derived from the Greek words "larynx", which means "throat", and "spasmos", which means "contraction".
Symptoms
Symptoms of laryngospasm include difficulty breathing, sudden coughing, a change in voice, and a sensation of choking or suffocation.
Causes
Laryngospasm can be caused by a variety of factors, including gastroesophageal reflux disease (GERD), asthma, allergies, exercise-induced bronchoconstriction, and certain medications. It can also occur during general anesthesia, particularly during induction or emergence.
Treatment
Treatment for laryngospasm typically involves addressing the underlying cause. This may include medication for conditions such as GERD or asthma, or changes in anesthesia technique for patients undergoing surgery. In severe cases, a procedure known as a tracheostomy may be necessary.
