Treatment for paroxysmal nocturnal dyspnea depends on the underlying cause. Options often include oxygen, diuretics, heart medications, antihypertensives, and bronchodilators to reverse wheezing.
Individuals can benefit from a variety of physical therapy interventions. Persons with neurological/neuromuscular abnormalities may have breathing difficulties due to weak or paralyzed intercostal, abdominal and/or other muscles needed for ventilation. Some physical therapy interventions for this population include active assisted cough techniques, volume augmentation such as breath stacking, education about body position and ventilation patterns and movement strategies to facilitate breathing.
Along with the measure above, systemic immediate release opioids are beneficial in emergently reducing the symptom of shortness of breath due to both cancer and non cancer causes; long-acting/sustained-release opioids are also used to prevent/continue treatment of dyspnea in palliative setting. Pulmonary rehabilitation may alleviate symptoms in some people, such as those with COPD, but will not cure the underlying disease. There is a lack of evidence to recommend midazolam, nebulised opioids, the use of gas mixtures, or cognitive-behavioral therapy.
The initial management of pulmonary edema, irrespective of the type or cause, is supporting vital functions. Therefore, if the level of consciousness is decreased it may be required to proceed to tracheal intubation and mechanical ventilation to prevent airway compromise. Hypoxia (abnormally low oxygen levels) may require supplementary oxygen, but if this is insufficient then again mechanical ventilation may be required to prevent complications. Treatment of the underlying cause is the next priority; pulmonary edema secondary to infection, for instance, would require the administration of appropriate antibiotics.
Acute cardiogenic pulmonary edema often responds rapidly to medical treatment. Positioning upright may relieve symptoms. Loop diuretics such as furosemide or bumetanide are administered, often together with morphine or diamorphine to reduce respiratory distress. Both diuretics and morphine may have vasodilator effects, but specific vasodilators may be used (particularly intravenous glyceryl trinitrate or ISDN) provided the blood pressure is adequate.
Continuous positive airway pressure and bilevel positive airway pressure (BIPAP/NIPPV) has been demonstrated to reduce the need of mechanical ventilation in people with severe cardiogenic pulmonary edema, and may reduce mortality.
It is possible for cardiogenic pulmonary edema to occur together with cardiogenic shock, in which the cardiac output is insufficient to sustain an adequate blood pressure. This can be treated with inotropic agents or by intra-aortic balloon pump, but this is regarded as temporary treatment while the underlying cause is addressed.
Paroxysmal nocturnal dyspnea or paroxysmal nocturnal dyspnoea (PND) refers to attacks of severe shortness of breath and coughing that generally occur at night. It usually awakens the person from sleep, and may be quite frightening. Though simple orthopnea may be relieved by sitting upright at the side of the bed with legs dangling, in those with PND, coughing and wheezing often persist in this position.
Treatment is with corticosteroids and possibly intravenous immunoglobulins.
Non-selective beta-blockers are the most effective in reducing the frequency and severity of PSH episodes. They help decrease the effect of circulating catecholamines and lower metabolic rates, which are high in patients during PSH episodes. Beta-blockers also help in reducing fever, diaphoresis, and in some cases dystonia. Propanolol is a common beta-blocker administered due to the fact that it penetrates the blood-brain barrier relatively well. Typically it is administered in doses of twenty milligrams to sixty milligrams every four to six hours in the treatment of PSH.
Morphine has been found to be effective in aborting episodes; sometimes it is the only medication that can combat the sympathetic response. Morphine helps lower respiration rates and hypertension. It is given in doses of two milligrams to eight milligrams but can be administered up to twenty milligrams. Nausea and vomiting are common side effects. Withdrawal is sometimes seen in patients.
Adenosine, an ultra-short-acting AV nodal blocking agent, is indicated if vagal maneuvers are not effective. If unsuccessful or the PSVT recurs diltiazem or verapamil are recommended. Adenosine may be safely used during pregnancy.
SVT that does not involve the AV node may respond to other anti-arrhythmic drugs such as sotalol or amiodarone.
If the person is hemodynamically unstable or other treatments have not been effective, synchronized electrical cardioversion may be used. In children this is often done with a dose of 0.5 to 1 J/Kg.
Middle-of-the-night insomnia is often treated with medication, although currently Intermezzo (zolpidem tartrate sublingual tablets) is the only Food and Drug Administration-approved medication specifically for treating MOTN awakening. Because most medications usually require 6–8 hours of sleep to avoid lingering effects the next day, these are often used every night at bedtime to prevent awakenings. Medication may not be prescribed in some cases, especially if the cause turns out to be the patient ingesting too much fluid during the day or just before they go to sleep.
Sleep restriction therapy and stimulus control therapy as described in insomnia have shown significance in treating middle of night insomnia.
Some studies have shown that zaleplon, which has a short elimination half-life, may be suitable for middle-of-the-night administration because it does not impair next day performance.
Most pharmacological treatments work poorly, but the best treatment is a low dosage of clonazepam, a muscle relaxant. Patients may also benefit from other benzodiazepines, phenobarbital, and other anticonvulsants such as valproic acid. Affected individuals have reported garlic to be effective for softening the attacks, but no studies have been done on this.
Simple behavioral methods are recommended as initial treatment. Enuresis alarm therapy and medications may be more effective but have potential side effects.
- Motivational therapy in nocturnal enuresis mainly involves parent and child education. Guilt should be allayed by providing facts. Fluids should be restricted 2 hours prior to bed. The child should be encouraged to empty the bladder completely prior to going to bed. Positive reinforcement can be initiated by setting up a diary or chart to monitor progress and establishing a system to reward the child for each night that he or she is dry. The child should participate in morning cleanup as a natural, nonpunitive consequence of wetting. This method is particularly helpful in younger children (<8 years) and will achieve dryness in 15-20% of the patients.
- Waiting: Almost all children will outgrow bedwetting. For this reason, urologists and pediatricians frequently recommend delaying treatment until the child is at least six or seven years old. Physicians may begin treatment earlier if they perceive the condition is damaging the child's self-esteem and/or relationships with family/friends.
- Bedwetting alarms: Physicians also frequently suggest bedwetting alarms which sound a loud tone when they sense moisture. This can help condition the child to wake at the sensation of a full bladder. These alarms are considered effective, with study participants being 13 times more likely to become dry at night. There is a 29% to 69% relapse rate, however, so the treatment may need to be repeated.
- DDAVP (desmopressin) tablets are a synthetic replacement for antidiuretic hormone, the hormone that reduces urine production during sleep. Desmopressin is usually used in the form of desmopressin acetate, DDAVP. Patients taking DDAVP are 4.5 times more likely to stay dry than those taking a placebo. The drug replaces the hormone for that night with no cumulative effect. US drug regulators have banned using desmopressin nasal sprays for treating bedwetting since the oral form is considered safer.
- DDAVP is most efficient in children with nocturnal polyuria (nocturnal urine production greater than 130% of expected bladder capacity for age) and normal bladder reservoir function (maximum voided volume greater than 70% of expected bladder capacity for age). Other children who are likely candidates for desmopressin treatment are those in whom alarm therapy has failed or those considered unlikely to comply with alarm therapy. It can be very useful for summer camp and sleepovers to prevent enuresis.
- Tricyclic antidepressants: Tricyclic antidepressant prescription drugs with anti-muscarinic properties have been proven successful in treating bedwetting, but also have an increased risk of side effects, including death from overdose. These drugs include amitriptyline, imipramine and nortriptyline. Studies find that patients using these drugs are 4.2 times as likely to stay dry as those taking a placebo. The relapse rates after stopping the medicines are close to 50%.
Diet alone cannot treat pacemaker syndrome, but an appropriate diet to the patient, in addition to the other treatment regimens mentioned, can improve the patient's symptoms. Several cases mentioned below:
- For patients with heart failure, low-salt diet is indicated.
- For patients with autonomic insufficiency, a high-salt diet may be appropriate.
- For patients with dehydration, oral fluid rehydration is needed.
Sometimes surgical intervention is needed. After consulting an electrophysiologist, possibly an additional pacemaker lead placement is needed, which eventually relieve some of the symptoms.
PKD patients usually show a good response to anticonvulsants. Most commonly used medications are sodium blockers, carbamazepine and phenytoin. During a drug-testing study, patients reported a decreasing response to the latter use of anticonvulsants and switched to carbamazepine or phenytoin. Refraining from established triggers such as sudden movement has been shown to lessen attacks occurrences. Avoidance of predisposing factors such as stress, excitement, and fatigue also help manage attacks.
No known treatment for BPT currently exists. However, the condition it is self-limiting and resolves after about eighteen months.
The most common drug used to treat AHC is flunarizine. Flunarizine functions by acting as a calcium channel blocker. Other drugs, in order of frequency of use are benzodiazepines, carbamazapine, barbiturates, and valproic acid. Flunarizine is prescribed for the purpose of reducing the severity of AHC attacks and the number of episodes, though it rarely stops attacks altogether. Minimizing the attacks may help reduce damage to the body from hemiplegic attacks and improve long-term outcomes as far as mental and physical disabilities are concerned.
Experts differ in their confidence in flunarizine's effectiveness. Some studies have found it to be very effective in reducing the duration, severity, and frequency of hemiplegic attacks. It is generally considered the best treatment available, but this drug is thought by some to be of little benefit to AHC patients. Many patients suffer adverse effects without seeing any improvement. Flunarizine also causes problems because it is difficult for patients to obtain, as it is not readily available in the United States.
Treatment for PKND is more difficult than other Paroxysmal Dyskinesias. The majority of patients experience some relief from low dosages of clonazepam, a muscle relaxant and anticonvulsant. Similar to PKD, avoidance of stress, excitement, and fatigue will lower the frequency of PNKD attacks. Many patients also avoid known methyglyoxal containing foods and beverages such as alcohol, coffee, tea, and chocolate.
Almost all patients respond positively to antiepileptic (anticonvulsant) drugs. One of the drugs most often mentioned in the literature is carbamazepine, and is the most widely used drug for treating PKD. Other anticonvulsants like valproic acid, phenytoin and clonazepam are common alternatives. Other categories of drugs have also been used, such as dopamine affecting drugs like Levodopa or Tetrabenazine. Individuals with the disorder can also modify their behavior to lessen their attacks without the influence of drug therapy. For example, decreasing stress to avoid precipitants can help patients decrease the number of attacks. In addition, avoiding any sudden movements can also prevent an attack. In order to prevent an attack, some individuals use their auras as a warning, while others purposefully perform slow gestures or movements prior to a triggering movement. Many, if not most, individuals end up growing out of the attacks with age, even without medicinal therapy, but some patients will go back to having attacks after a period of remission. In regards to secondary PKD, treatment of the primary condition can lessen the PKD attacks in those individuals.
Current research at the University of Utah is investigating whether sodium oxybate, also known as Gamma-Hydroxybutyric acid is an effective treatment for AHC. Thus far, only a small number of patients have been sampled, and no conclusive results are yet available. While some success has been had thus far with the drug, AHC patients have been known to respond well initially to other drugs, but then the effectiveness will decline over time. Currently, sodium oxybate is used as a narcolepsy-cataplexy treatment, though in the past it has been used controversially in nutritional supplements. This drug was chosen to test because of a possible link between the causes of narcolepsy-cataplexy and AHC.
The tumor must be surgically removed. Some patients will also need their mitral valve replaced. This can be done during the same surgery.
Myxomas may come back if surgery did not remove all of the tumor cells.
Endogenous lipoid pneumonia and non-specific interstitial pneumonitis has been seen prior to the development of pulmonary alveolar proteinosis in a child.
Night sweats, also known as nocturnal hyperhidrosis, is the occurrence of excessive sweating during sleep. The person may or may not also suffer from excessive perspiration while awake.
One of the most common causes of night sweats in women over 40 is the hormonal changes related to menopause and perimenopause. This is a very common occurrence during the menopausal transition years.
While night sweats might be relatively harmless, it can also be a sign of a serious underlying disease. It is important to distinguish night sweats due to medical causes from those that occur simply because the sleep environment is too warm, either because the bedroom is unusually hot or because there are too many covers on the bed. Night sweats caused by a medical condition or infection can be described as "severe hot flashes occurring at night that can drench sleepwear and sheets, which are not related to the environment". Some of the underlying medical conditions and infections that cause these severe night sweats can be life-threatening and should promptly be investigated by a medical practitioner.
