Dog coughing after surgery, and the surgeon has no choice but to remove it before the lung heals. What do you think happens to the rest of his lung?

Answer:

There are many forms of pneumonia and it's important to understand how and why your symptoms develop, for if you get quick and effective care your chance of getting well from pneumonia is very good. This patient's symptoms are most likely due to aspiration of secretions that occur from surgery for emphysema.

When the lung is removed, secretions collect in the cavity, causing inflammation. That cavity is called a pleural effusion. The process is known as the "lung auto-defense mechanism" and can cause pneumonia to develop in that area. This type of pneumonia is known as "pneumonic effusion." In people with emphysema, the pneumonia may be caused by an infection that is spreading from the lungs to the chest cavity. This is called secondary pneumonia.

In some instances, surgery results in pleural space infection which requires treatment. When secretions from the lung collect in the chest cavity, fluid may collect in the space surrounding the lungs. The fluid is called a pleural effusion. In patients with emphysema, the lung is likely to continue to break down. This material may break through the protective skin lining the lung, leading to infection and requiring further surgery. In some patients, the fluid that is formed by the breakdown of lung tissue is so large that it causes the chest wall to become swollen and tight and may even limit the patient's ability to take in a full breath. This, called a pneumothorax, needs to be treated with immediate thoracic surgery. The most common treatment for both emphysema and a pneumothorax is to drn the effusion into a small cavity called a chest tube. In some patients, surgery is also done to remove part of the lung or part of the rib that is blocking the rway.

Pneumothorax is treated with a needle or catheter, to create a small opening into the chest, and this will allow r to enter the chest and allow breathing. When a patient is not being operated on, or when chest tubes are not drning the pleural space, the lung is at risk of being reinfected. When patients with emphysema undergo surgery, their ability to re-inflate their lungs is at risk if the chest tubes cannot be placed or they are unable to breathe on their own. Therefore, these patients are hospitalized, and a ventilator is used to support breathing until they are able to take in more oxygen.

Prognosis

When emphysema is caught early, there is a good chance for cure or long-term improvement in lung function.

Treatments

Progressive emphysema, or severe pulmonary artery obstruction, is typically treated with oxygen therapy and inhalation medications. Inhaled nitric oxide (iNO) may be used to reduce pulmonary hypertension and improve gas exchange. Lung transplantation may be used to treat patients who are not candidates for other treatments.

History

Emphysema, also called "chronic obstructive pulmonary disease" (COPD), was first described in the 1950s. Its cause was not known, but it became more common in the 1960s with the increase of cigarette smoking. It is now recognized as the fourth-leading cause of death in the United States, and cigarette smoking is estimated to account for more than 20% of cases.

Research directions

Research is being done to find treatments that will help prevent the disease from getting worse. A promising treatment is hyperbaric oxygen therapy. It has shown some efficacy in short-term trials. In some studies, inhaled nitric oxide has also shown benefits. A proposed treatment is a stem cell therapy which shows some promise. Also, a proposed treatment is a medication called "recombinant human alpha1 antitrypsin" which is meant to prevent alveolar destruction.
