Some Essential Concepts Regarding Aspiration Pneumonia Prevention

By Martha Wilson


Aspiration usually occurs as a result of lack of control of muscles in the upper gastrointestinal system. Inability to control food propulsion and swallowing may result in some of the digested food material getting into the respiratory tract. When this happens, the affected individual may suffer from what is termed aspiration pneumonia. It is, therefore, prudent to observe aspiration pneumonia prevention measures particularly for high risk groups. Some of these high risk groups include the aged, those with neuromuscular diseases, surgical patients and those who spend a long time in the intensive care unit.

Among the key ways to prevent the condition is to insert a nasogastric tube for patients who experience difficulties swallowing food because of paralysis of their muscles. It is important to put such patients under sedation so that the procedure can be done smoothly without agitating them. This conduit runs from the nostril to the pit of the stomach.

The caregiver should be careful not to clog the tube by limiting the foods to semi solids and liquids. The feeds need to be given after they have cooled down so that the stomach lining does not get corroded. Some of the common feeds administered include tea, milk and porridge. Also, the conduit needs to be replaced frequently with a clean one to reduce the risk of getting new infections.

Examples of feeds given through an NGT include milk, porridge and specially prepared commercial fluids of high nutritional value. Before deciding to feed the patient using an NGT, assisted feeding through the mouth should first be attempted. Patience is needed during assisted feeding to prevent the patient from choking. In addition, only soft foods should be given at this point.

Stroke is among the medical disorders in which insertion of a nasogastric tube may be indicated. This is because stroke patients are at risk of aspirating since their muscles become paralyzed suddenly. Some of the conditions that predispose one to getting a stroke include diabetes, hypertension and cardiac disease. Any patient diagnosed with stroke should be examined to ascertain whether or not they can comfortably take in oral feeds.

The importance of nursing the patient in a propped up position cannot be overemphasized. Elevating the head of the bed not only keeps the patient comfortable but it also ensures that any food remnants are directed downwards along the gastrointestinal tract. The patient can also be made to lie on one side to minimize regurgitation.

Patients being nursed in intensive care units over a long period of time are also likely to aspirate. Apart from propping them up and feeding them through a nasogastric tube, intubation also helps to separate the trachea from the food pipe. Those with chronic conditions also need to be monitored closely for any complications that may arise. This includes doing imaging studies of the lungs to detect any abnormalities.

In summary, aspiration pneumonia comes about when digested food goes into the respiratory tract instead of down the esophagus to the stomach. The elderly and those with disorders of nerves and muscles are the most likely to aspirate. Prevention involves assisted feeding and propping up.
