Rare Tracheal Condition Can Mimic Asthma, Prompting Call for Vigilance After Intubation
SUZHOU, China — A recent case is highlighting the importance of vigilance in recognizing a rare but perhaps deadly complication following endotracheal intubation, particularly in patients with chronic obstructive pulmonary disease (COPD). Post-intubation tracheal stenosis (PITS), a narrowing of the trachea (windpipe) after intubation, can sometimes be misdiagnosed as asthma, leading to delayed treatment and potentially fatal consequences.
The case, detailed by doctors, involved a COPD patient who developed tracheal stenosis after just 28 hours of intubation for an acute exacerbation of their condition. While intubation lasting more than 48 hours is a well-known risk factor for PITS, this case underscores the possibility of the condition developing even after shorter periods. This patient was successfully treated with bronchoscopic cryotherapy, a procedure that uses extreme cold to destroy abnormal tissue.
“Tracheal stenosis following intubation in the ICU is a rare but serious problem,” researchers noted, adding that emergency intubation, undersedation, and cuff pressure have all been associated with PITS.
The patient in this report had routine daily monitoring of cuff pressure and endotracheal tube position conducted in the RICU. “So, light sedation during mechanical ventilation, emergency intubation and inflammatory response around the cuff may be the primary risk factor for the short-term development of PITS in this patient.”
According to the National Institutes of Health, the incidence of post-intubation laryngotracheal stenosis in adults has been documented at a rate of 4.9 cases per million per year. The agency also explains that tracheal stenosis primarily results from long-term granulation and scar formation,but it can also be caused by short-term edema,ischemic necrosis,inflammation,and other complex acute mucosal lesions in the cuff area,leading to acute airway stenosis.The patient developed severe wheezing four days after extubation. It was initially misdiagnosed as another acute exacerbation of COPD (AECOPD),delaying crucial CT scans and bronchoscopy by nearly seven hours. “Despite the patient’s wheezing being refractory to both intravenous steroids and inhaled bronchodilators, ultimately leading to respiratory failure,” doctors continued to treat the patient for AECOPD before recognizing their actual affliction.
This near miss highlights a critical point. “The exacerbation of severe wheezing in COPD patients may not always indicate AECOPD, particularly in those with a recent history of emergency endotracheal intubation,” the authors cautioned. “PITS in COPD patients should be recognized as an emergency and need early identification.”
Interventional bronchoscopy, where a thin, flexible tube with a camera is inserted into the airways, is frequently used as the frist-line treatment. Laser therapy and dilatation (widening the airway) are common methods. In this particular case, bronchoscopic cryotherapy proved successful. Tissue samples of necrosis and inflammatory exudate from the stenotic area within the tracheal lumen were obtained using bronchoscopic cryotechnology. Histopathological examination revealed inflammatory exudate and necrotic material.
While prolonged intubation remains the most significant risk factor, cases like this emphasize the need for increased awareness and prompt action even after short intubation periods.
One potential counterargument to the emphasis on short-term PITS is its rarity. Critics might argue that focusing on such uncommon occurrences could lead to unnecessary testing and anxiety. However, proponents stress that the severe consequences of a missed diagnosis outweigh the risk of occasional over-testing. A delayed diagnosis can lead to respiratory failure, the need for more invasive procedures, and even death. More recent studies are confirming the effectiveness of prompt bronchoscopic intervention in improving patient outcomes.
FAQ: Post-Intubation Tracheal Stenosis (PITS)
What is post-intubation tracheal stenosis (PITS)? PITS is a narrowing of the trachea that occurs as a complication after a patient has been intubated (had a breathing tube placed in their windpipe).
How common is PITS? PITS is relatively rare, with an incidence of about 4.9 cases per million adults per year.
What are the symptoms of PITS? Symptoms can include wheezing, shortness of breath, difficulty breathing, stridor (a high-pitched breathing sound), and a persistent cough. How is PITS diagnosed? PITS is typically diagnosed through a combination of imaging tests (such as CT scans) and bronchoscopy.
* How is PITS treated? Treatment options include bronchoscopic procedures (such as dilatation or cryotherapy) to widen the airway, and in severe cases, surgery.
This case serves as a reminder that vigilance and a high index of suspicion are crucial for healthcare professionals to provide the best possible care for intubated patients,especially those with underlying conditions like COPD.

Interview: Shining a Light on Post-Intubation Tracheal Stenosis – An Expert’s Insight
archyde News Editor: Welcome,Dr. Anya Sharma, to Archyde News. We appreciate you taking the time to discuss this critical issue of Post-Intubation Tracheal Stenosis (PITS) following a recent case highlighting the need for vigilance.
Dr. Anya Sharma, Pulmonologist: Thank you for having me. It’s crucial to raise awareness about this possibly serious complication.
Understanding Post-Intubation Tracheal Stenosis (PITS)
Archyde News Editor: To begin, could you briefly explain what post-intubation tracheal stenosis is and why it’s a concern, especially after shorter intubation periods, as witnessed in the case we discussed?
Dr. Sharma: Certainly. PITS,as the name suggests,is a narrowing of the trachea,or windpipe,that can occur *after* a patient has been intubated,meaning a breathing tube was inserted. while prolonged intubation is a well-known risk, this case, as well as others, shows that it can happen sooner than we often anticipate. Even short-term intubation, especially in patients with pre-existing conditions like COPD, can trigger PITS, potentially leading to breathing difficulties that can mimic asthma or exacerbations of COPD.
The Challenge of Misdiagnosis
Archyde News Editor: The case highlighted the risk of misdiagnosis. Why is it so easy to mistake PITS for something else, and what are the consequences of such a misdiagnosis, as outlined in the research?
Dr. Sharma: The symptoms of PITS, such as wheezing and shortness of breath, can easily be mistaken for an exacerbation in existing conditions like Asthma or COPD. A misdiagnosis is dangerous due to the delay in appropriate treatment that it may cause. Misdiagnosis can lead to a delay in the effective treatment,which can lead to respiratory failure,invasive procedures,and,in severe cases,even life-threatening scenarios.
risk factors and Vigilance
archyde News Editor: The study emphasized that even with careful monitoring of cuff pressure,PITS can still occur.Are there other risk factors besides the duration of intubation that doctors should be looking out for?
Dr. Sharma: Absolutely. The study suggests that factors like light sedation during mechanical ventilation and the inflammatory response at the cuff site could be risk factors. We need to be acutely aware of how the endotracheal tube interacts with the tracheal wall. It also underlines why a high index of suspicion is crucial. Emergency intubation, particularly, seems to add to the risk.
Diagnostic and Treatment Approaches
Archyde News Editor: What are the key steps in diagnosing and treating PITS, as referenced in the research?
Dr. Sharma: Early diagnosis is extremely important. Neck and chest CT scans are crucial. Bronchoscopy is another essential tool, as it allows us to visualize and even treat the narrowing. Interventional bronchoscopy, including methods like dilatation, laser therapy, and cryotherapy, is often the first line of treatment, as was triumphant in the recent case.
The Importance of Proactive Approaches
Archyde News Editor: Finally what is the take away for the healthcare community?
Dr. Sharma: The primary takeaway is vigilance. When considering the diagnosis and treatment pathway, especially in patients with recent intubation, we need to be very alert for signs of PITS.A patient’s wheezing should not automatically be considered an exacerbation of their previous conditions. Early diagnosis and appropriate intervention – likely through bronchoscopy – lead to improved patient outcomes. Proper, and consistent monitoring of cuff pressure during intubation is also critical.
A Call for discussion
Archyde News Editor: Thank you, Dr. Sharma, for providing such valuable insights. Do you believe that the increased emphasis on shorter intubation and early intervention requires changes to established protocols in icus, or is this more a matter of raising awareness?
Dr. Sharma: That’s a very important question. I believe it’s both. Raising awareness is critical to change how clinicians think and react. But we may also have to question the very way we manage intubated patients, especially those that are high-risk, such as those that have chronic respiratory conditions like COPD. We must be very cautious of the inflammatory processes that can take place around the ET tube cuff, as well as the need for early intervention such as bronchoscopy.
Archyde News Editor: Thank you, Dr. Sharma, for taking the time to speak with us. This has been highly informative.
