Nursing diagnoses for ALS

Five key nursing diagnoses:

1. Potential for injury related to impaired physical mobility.

2. Impaired urinary elimination related to progressive loss of mobility.

3. Knowledge deficit regarding alternatives for diet, food preparation, and alternative procedures for supplemental feeding.

4. Ineffective airway clearance related to impaired or absent gag reflex, swallowing reflex, or sneeze reflex.

5. Impaired gas exchange related to aspiration secondary to impaired or absent gag, swallowing, and cough reflex.

Nursing Diagnosis	Actual or potential	Related to	Plan and outcome	Nursing intervention
Ineffective airway clearance	Actual	Related to impaired or absent gag, swallowing, or sneeze reflex	Maintain airway patency and adequate ventilation	- Deep breathing and coughing exercises and use of incentive spirometer to encourage lung expansion - Use of aspirator to suction secretions and prevent choking - Chest physiotherapy: percussion, assisted cough and postural drainage when indicated

Nursing Care for Individuals with ALS

Nursing Care	Details	Nursing diagnoses	Reasoning
1. Assessing muscle weakness	- Assess motor strength; presence of flaccidity or spasticity - Assess presence of contracture	- Potential for injury related to impaired physical mobility - Knowledge deficit regarding prevention of injury while promoting mobility and self-care	A nurse wants to promote daily activity and exercise as tolerated for the individual. This hopes to strengthen unaffected muscle groups without fatiguing affected muscles. ROM exercises can help prevent contracture and pain in joints.
2. Assessing skin status	- Assess skin daily, especially areas susceptible to breakdown - Change patient’s body position every two hours	- Alteration in comfort - Risk for skin integrity	As the patient’s mobility becomes limited, nurses want to maintain skin integrity by changing body position as much as needed, in order to prevent decubitis ulcers.
3. Assessing Urinary function	- Assess urination pattern and patterns of fluid intake - Assess ability to transfer to toilet or commode, or standing ability of a male - Assess for signs and symptoms of UTI	- Impaired urinary function related to progressive loss of mobility	Nurses need to encourage daily fluid intake of 2500 cc’s per day unless contraindicated because of swallowing ability. Staying on top of UTI’s is important to the patient’s comfort and health.
4. Assessing altered bowel function	- Assess bowel pattern (for constipation, diarrhea, impaction) - Assess diet, fluid intake, and swallowing ability - Assess activity level	- Impaired bowel elimination - Progressive loss of mobility - Progressive decline of dietary fiber - Often mild/moderate dehydration - Progressive inability of the trunk muscles to support a normal posture to assist in defaction	Nursing care is focused on preventative measures for bowel dysfunction, like administering stool softeners and promoting fluid intake. Having a daily record of bowel movements is important to identify regular patterns. Providing dietary regarding the importance of fiber, unless contraindicated because of swallowing ability.
5. Assessing nutritional needs	- Measuring height, pre-morbid “usual weight”, current weight, weight gain/loss pattern since onset of disease, and “ideal body weight” - Lab test indicated if patienthas lost 10% or more of body weight in last two months - Assess hydration status by carefully recording intake and output and by test of urine specific gravity	- Risk of inadequate nutritional intake	Being aware of the patient’s previous nutritional status and weight is important in comparing it to their current or progressing states of nutrition, in order to maintain adequate nutritional intake and have goals to put in place for the patient.
6. Assessing dysphagia and management of nutrition	- Assess gag, cough and swallowing reflexes, and chewing - Assess patient’s ability to swallow liquids and solids - Assess weight serially	- Potential for injury - Impaired nutritional status - Knowledge deficit regarding alternatives for diet, food preparation, and alternative procedures for supplemental feeding	Discussing techniques of protecting airway, i.e. sitting up straight, putting chin on chest while swallowing, concentrating while eating,are good preventative measures to keep patient involved and aware of their risk of dysphagia.
7. Assessing respiratory function	- Gather history of subjective symptoms, like SOB in relation to positional changes, fatigue - Assess changes from baseline respiratory rate, depth, pattern, chest expansion - Auscultate decreased breath sounds, presence of extra or adventitious sounds	- Ineffective airway clearances related to impaired/ absence gag reflex, swallowing reflex, or cough/sneeze reflex - Impaired gas exchange related to aspiration secondary to impaired/ absent gag, swallowing, or coughing reflex - Knowledge deficit regarding airway clearance and gas exchange; considerations regarding mechanical life supports	Nurse’s primary goals are maintaining airway patency by using an aspirator to suction secretions and prevent choking, and use of medications. Also maintaining adequate ventilation by cough and deep breathing exercises with an incentive spirometer to encourage lung expansion, using oxygen when ordered.
8. Assessing ability to communicate	- Assess volume and clarity of speech - Assess ability to communicate needs to family/significant others	- Impaired verbal communication related to altered volume of speech, altered clarity of speech, or loss of speech.	Nurses can refer to a speech pathologist for evaluation and intervention.
9. Assessing the patient’s psychological adaptations	- Evaluate the patient and family’s support systems and coping patterns with awareness that with ongoing loss of independence, there will be ongoing grieving by patient and family.	- Ineffective coping strategies - Knowledge deficit regarding alternatives for mobility and comfort - Impaired support system	Nurses need to provide an accepting environment in which the patient and family can share concerns and fears with each other and members of the health care team. Nurses need to help the patient and family anticipate care needs and implications.

Treatment of ALS

Since there is no cure for ALS today, there are various options of treatment that aim to slow the progression of the disease. These include disease directed therapy, symptom related therapy, and respiratory management that helps the patient maintain the ability to breathe even when their muscles are degenerating.

Disease directed therapy

There is only one drug that has been approved to treat ALS, called Ritulek. Studies on Ritulek have shown that the drug helps protect nerve cells from damage, most likely by reducing the amount of glutamate in the nervous system. Although this drug is meant to help protect the nerve cells from disease damage, once nerve cells have been impaired, this drug does not repair them or gain their function back - it only slows progression of the disease.

Symptom related therapy

As ALS progresses, symptoms worsen. In symptom related therapy, the goal is to increase patients' quality of life by alleviating these symptoms. Due to the fatality of ALS, alleviating the symptoms' impact on the patient's life is important. The most common symptoms include muscle contractions, cramps, stiffness, weakness, fatigue, depression, sleeping, and saliva and drooling. To help improve muscle function before flaccidity takes over, often patients work with physical and occupational therapy. They can begin using walking assistance devices like walkers, and eventually wheel chairs and electrical chairs. 

Respiratory management
In ALS, as muscle degeneration progesses, several problems cause increased difficulty in breathing. 

As this picture indicates, there are several important muscles in the ribcage and diaphragm that help your lungs expand to inhale air, and deflate to exhale. As these muscles weaken, oxygen cannot be adequately exchanged and carbon dioxide builds up in the blood stream, leading to sleepiness and fatigue. Also, without the strength of these breathing muscles, the ability to clear secretions and cough adequately is diminished. This can lead to pneumonia, and even diminish the ability to clear the airway adequately. Treatments for this are directed at decreasing and thinning secretions as well as increasing clearance. 

As the difficulty to breathe progresses, there are options to physically help the patient through ventilation; there is non-invasive ventilation and eventually invasive ventilation if needed. The noninvasive ventilator is triggered and controlled by the patient's own breathing, and reduces the work for the patient since their weakness prohibits them from being able to breath adequately on their own. This improves the exchange of oxygen and carbon dioxide, improving sleep quality. Non-invasive ventilation has also been shown to prolong survival as well as improve the quality of life.

Once a person with ALS becomes ultimately dependent on ventilation to breathe, they will require a tracheostomy to be placed, which is a tube insertion into the airway. This provides more efficient ventilation and better control of airway secretions.

Identifying the Signs and Symptoms of ALS

According to the ALS association, the early signs and symptoms of ALS may be so subtle and slight that they can be overlooked. These early symptoms don't arise in the same order or presentation from patient to patient, and the progression of the disease varies between individuals. One individual might have trouble walking and trip or experience foot-drop. Another may have slurred or altered speech, while another may have muscle weakness in the upper extremities or decreased dexterity in the hands.

Early signs and symptoms of ALS

Muscle weakness is considered a hallmark initial sign of ALS, occurring in approximately 60% of patients. The disease progresses by increasing weakness and paralysis in the muscles throughout the body, and eventually effects speech, swallowing, chewing and breathing.

Because ALS only attacks motor neurons, patients do not experience deficits in the sense of touch, hearing, taste, smell, or sight.
