| ==Overview== | | ==Overview== |
| Cough in kids is one of the most common presenting complaint to pediatricians. importantly cough is not disease by itself but rather a manifestation of underlying pathology.
| | This section provides a short and straight to the point overview of the disease or symptom. The first sentence of the overview must contain the name of the disease. |
| | |
| A cough is protective action and can be initiated both voluntary and via stimulation of cough respiratory located throughout the respiratory tract (ear – sinus – upper and lower airway )
| |
| | |

| | |
| ======Cough is usually classified based on======

| | | {{familytree | | | | | | | | A01 |A01= }} |
| cough is a symptom of an underlying condition should be discussed with the patient and

| | {{familytree | | | | | | | | | | |!| | | | |!| }} |
| | | {{familytree | | | | | | | | | | F01 | | | F02 |F01= |F02= }} |
| an important component of the body’s natural response to the primary illness, and
| | {{familytree/end}} |
| | |
| suppressing the cough in the absence of effective therapy of the primary disorder may actually
| |
| | |
| worsen the problem.
| |
| | |
| Treatment of the underlying disorders causing cough is discussed in other sections of
| |
| | |
| this book; this chapter is limited to a review of medications used to treat cough itself. The
| |
| | |
| decision to use a cough medicine as an adjunct to the treatment of the primary disease is left
| |
| | |
| to the primary care physician and family. When cough is limiting or otherwise debilitating
| |
| | |
| the patient, symptomatic treatment may be attempted; however numerous studies question
| |
| | |
| whether over-the-counter cough preparations offer any significant clinical benefit.
| |
| | |
| In addition these cough and cold medications should not be given to children younger than
| |
| | |
| 4 years because serious and potentially life-threatening side effects can occur from their
| |
| | |
| use. Finally, several studies have shown that honey may be beneficial in children older
| |
| | |
| than 2 years of age.
| |
| | |
| | |
| '''''Expectorants'''''
| |
| | |
| Expectorants such as guaifenesin (formerly known as glyceryl guaiacolate) may be used
| |
| | |
| in an attempt to make secretions more fluid and reduce sputum thickness, however the
| |
| | |
| effectiveness of this treatment has been called into question. This therapeutic approach
| |
| | |
| may be useful when drainage of secretions is important, as with sinusitis. Because expectorants
| |
| | |
| work by increasing the fluid content of secretions, water is probably the most
| |
| | |
| effective expectorant. Saline nose sprays can make secretions more fluid and easily cleared
| |
| | |
| by the patient and systemic hydration, but not overhydration, should always be optimized.
| |
| | |
| Despite widespread use, expectorants have not been shown to decrease cough in children.
| |
| | |
| Other older expectorants, such as potassium iodide and ammonium chloride, are no
| |
| | |
| longer prescribed to children because of their adverse effects when used at effective doses.
| |
| | |
| | |
|
| |
| | |
| | |
| | |
| '''''Mucolytic Agents'''''
| |
| | |
| Acetylcysteine was previously used as a mucolytic agent to help liquefy thick secretions,
| |
| | |
| especially in diseases such as cystic fibrosis; however, its propensity for inducing airway
| |
| | |
| reactivity and inflammation has lately made it less popular.
| |
| | |
| | |
| '''''Cough Suppressants'''''
| |
| | |
| Cough suppressants, which can be divided into peripheral and centrally acting agents,
| |
| | |
| can be effective in transiently decreasing cough severity and frequency. Peripheral agents
| |
| | |
| include demulcents (eg, throat lozenges), which soothe the throat, and topical anesthetics,
| |
| | |
| which can be sprayed or swallowed. Topical agents block the cough receptors, but their
| |
| | |
| effects are short-lived because oral secretions rapidly wash them away. Centrally acting
| |
| | |
| cough suppressants, including both narcotic and nonnarcotic medications, suppress
| |
| | |
| the cough reflex at the brain stem level. The narcotic agent most commonly used in
| |
| | |
| children is codeine. Although it has been shown to be effective in adults, studies on its
| |
| | |
| safety and efficacy in children are lacking. Furthermore, data from adults should not be
| |
| | |
| extrapolated to children, particularly those younger than 2 years, because the metabolic
| |
| | |
| pathway for clearance of codeine is immature in infants. In older children, codeine should
| |
| | |
| still be avoided and only used in extreme cases and with very clear instructions because of
| |
| | |
| the unpredictable and potentially dangerous variation of its metabolism in the pediatric
| |
| | |
| population. Other agents, such as hydrocodone, have no demonstrated advantage and
| |
| | |
| pose a greater risk of dependency. Dextromethorphan (the dextro-isomer of codeine) is
| |
| | |
| the most commonly used nonnarcotic antitussive; and despite data from adults, evidence
| |
| | |
| of efficacy for children is lacking.
| |
| | |
| | |
| '''''Decongestants'''''
| |
| | |
| Decongestants such as pseudoephedrine can be used either topically or systemically
| |
| | |
| to decrease nasal mucosal swelling. Decongestants can also facilitate sinus drainage by
| |
| | |
| decreasing sinus ostia obstruction, and may work well in combination with expectorants
| |
| | |
| to optimize treatment of chronic sinusitis. Care should be taken in the use of these
| |
| | |
| agents because they have been shown to lead to tachyarrhythmias in individuals who use
| |
| | |
| them in excess. In addition, these agents have not been studied in children and should
| |
| | |
| be avoided in children younger than 2 years. Multiple reviews of the data from children
| |
| | |
| between 2 and 6 years old also show lack of efficacy combined with a risk of side effects
| |
| | |
| in this age group. It is therefore recommended that these agents not be used in children
| |
| | |
| younger than 6 years.
| |
| | |
| | |
| '''''Antihistamines'''''
| |
| | |
| Antihistamines, which can be helpful in the treatment of cough triggered by allergy, have
| |
| | |
| minimal effect when cough is the result of viral or bacterial infection and may actually be
| |
| | |
| detrimental because they can increase the thickness of secretions. First-generation H1-receptor
| |
| | |
| antagonists may decrease nasal drip by exerting an anticholinergic effect. Additionally,
| |
| | |
| diphenhydramine may have a modest direct effect on the medullary cough center. The
| |
| | |
| clinical benefits of these agents are unclear.
| |
| | |
| | |
| '''When to Refer'''
| |
| | |
| • Cough persists despite adequate therapy of primary disease
| |
| | |
| • Cough thought to be from hyperreactive airways is not easily reversible with _Beta-2 agonist
| |
| | |
| • Cough recurs more frequently than every 6 to 8 weeks
| |
| | |
| • Cough associated with failure to thrive
| |
| | |
| • Cough associated with other systemic illness
| |
| | |
| | |
| '''When to Admit'''
| |
| | |
| • Patient has respiratory distress
| |
| | |
| • Infant is unable to feed
| |
| | |
| • Cough is associated with bacterial pneumonia not responsive to oral antibiotic trial
