Summary
Persistent cough after pulmonary resection affects 21.1% of patients, often presenting as a dry cough. Mediastinal lymph node removal and right upper lobe resection are key risk factors for this common complication.
Area of Science:
- Thoracic Surgery
- Pulmonary Medicine
- Clinical Outcomes Research
Background:
- Persistent cough is a common post-pulmonary resection complication impacting patient quality of life.
- Limited data exists on the clinical characteristics and risk factors for persistent cough following pulmonary resection.
- This study addresses the need for a comprehensive description of post-resection cough.
Purpose of the Study:
- To characterize the clinical presentation of persistent cough after pulmonary resection.
- To identify independent risk factors associated with persistent cough post-pulmonary resection.
Main Methods:
- Retrospective analysis of 901 patients undergoing thoracoscopic pulmonary resection.
- Description of persistent cough characteristics.
- Univariable and multivariable regression analyses to determine risk factors.
Main Results:
- Persistent cough occurred in 21.1% of patients, typically a dry cough starting around postoperative day 7 and lasting approximately 5 months.
- Triggers included pungent smells, cold air, deep inhalation, speaking, postural changes, and emotional excitement.
- Right upper lobe resection (OR 2.311) and mediastinal lymph node removal (OR 3.686) were significant independent risk factors.
Conclusions:
- Persistent cough is a frequent complication post-pulmonary resection requiring greater clinical attention.
- Mediastinal lymph node removal and right upper lobe resection are identified as independent risk factors.
- Understanding these risk factors can inform surgical strategies and patient management.

COPD is defined as a heterogeneous lung condition marked by persistent respiratory symptoms such as dyspnea, cough, and sputum production, caused by abnormalities in the airways that cause airflow obstruction.
Smoking is a primary risk factor for COPD, with over 80% of patients having a history of it. Patients typically experience progressive dyspnea or labored breathing, frequent coughing, and recurrent pulmonary infections. Many eventually succumb to respiratory failure, characterized by...

01:17Pulmonary Cycle: Exhalation
1.8K
In terms of human respiration, the act of expelling air, known as exhalation (or expiration), operates on the principle of pressure gradients. During expiration, the pressure within the lungs exceeds that of the surrounding atmosphere. Under normal conditions, quiet breathing involves passive exhalation and is free of muscular contractions. This is because the exhalation process is driven by the natural elastic recoil of the lungs and chest wall, both of which have an inherent tendency to...

Understanding the variety of primary symptoms and systemic complications that characterize chronic obstructive pulmonary disease (COPD) is crucial for healthcare professionals.
Symptoms of COPD can be classified as primary or systemic. Primary symptoms relate to reduced airflow, while systemic or extrapulmonary symptoms relate to COPD's broader impact on the body.

2.9K
Chronic Obstructive Pulmonary Disease (COPD) is a long-lasting respiratory condition requiring continuous attention and care. It is a progressive lung disease that leads to breathing challenges due to airflow obstruction. It manifests as persistent respiratory symptoms and restricted airflow resulting from abnormalities in the airways and alveoli, usually due to long-term exposure to harmful particles or gases. COPD mainly consists of two primary conditions: emphysema and chronic bronchitis.

Chronic obstructive pulmonary disease (COPD) is a group of lung conditions that progressively worsen over time, including chronic bronchitis and emphysema. This cluster of diseases collectively leads to a gradual and irreversible decline in lung function over time.
The primary cause for the onset of COPD is cigarette smoking and exposure to air pollution. These hazardous factors initiate a chain reaction within the lungs, resulting in chronic inflammation, damage to the airways, and a...

Nursing management of Chronic Obstructive Pulmonary Disease (COPD) is crucial for providing thorough care and support to patients. Nurses play an integral role in this process through detailed assessment, careful planning, targeted interventions, and ongoing evaluation. Here's an overview of the critical steps in nursing management for COPD.
