特徴的な咳

小児の咳嗽は、咳を聴くだけで診断できるものがある。
クループや百日咳などが典型的である。
百日咳では、連続性の咳(staccato)が数回発作性に続くため、息を吸うことができず、その後「ヒュー」という甲高い吸気が聞こえる(whoop)。staccatoとwhoopの繰り返しをrepriseという。舌圧子で咽頭を刺激すると誘発されることがある。

1: Guidelines for evaluating chronic cough in pediatrics: ACCP evidence-based clinical practice guidelines.
著者: Anne B Chang, William B Glomb, )
雑誌名: Chest. 2006 Jan;129(1 Suppl):260S-283S. doi: 10.1378/chest.129.1_suppl.260S.
Abstract/Text: OBJECTIVES: To review relevant literature and present evidence-based guidelines to assist general and specialist medical practitioners in the evaluation and management of children who present with chronic cough.
METHODOLOGY: The Cochrane, MEDLINE, and EMBASE databases, review articles, and reference lists of relevant articles were searched and reviewed by a single author. The date of the last comprehensive search was December 5, 2003, and that of the Cochrane database was November 7, 2004. The authors' own databases and expertise identified additional articles.
RESULTS/CONCLUSIONS: Pediatric chronic cough (ie, cough in children aged <15 years) is defined as a daily cough lasting for >4 weeks. This time frame was chosen based on the natural history of URTIs in children and differs from the definition of chronic cough in adults. In this guideline, only chronic cough will be discussed. Chronic cough is subdivided into specific cough (ie, cough associated with other symptoms and signs suggestive of an associated or underlying problem) and nonspecific cough (ie, dry cough in the absence of an identifiable respiratory disease of known etiology). The majority of this section focuses on nonspecific cough, as specific cough encompasses the entire spectrum of pediatric pulmonology. A review of the literature revealed few randomized controlled trials for treatment of nonspecific cough. Management guidelines are summarized in two pathways. Recommendations are derived from a systematic review of the literature and were integrated with expert opinion. They are a general guideline only, do not substitute for sound clinical judgment, and are not intended to be used as a protocol for the management of all children with a coughing illness. Children (aged <15 years) with cough should be managed according to child-specific guidelines, which differ from those for adults as the etiologic factors and treatments for children are sometimes different from those for adults. Cough in children should be treated based on etiology, and there is no evidence for using medications for the symptomatic relief of cough. If medications are used, it is imperative that the children are followed up and therapy with the medications stopped if there is no effect on the cough within an expected time frame. An evaluation of the time to response is important. Irrespective of diagnosis, environmental influences and parental expectations should be discussed and managed accordingly. Cough often impacts the quality of life of both children and parents, and the exploration of parental expectations and fears is often valuable in the management of cough in children.

特異的咳嗽の指標

特異的咳嗽は咳嗽の原因になる呼吸器疾患または全身性疾患の存在を示唆する症状や徴候がある咳である。表の特異的咳嗽の指標がある場合は、原因疾患の診断を開始するべきである。
非特異的咳嗽は特異的咳嗽がない乾性咳嗽で、自然軽快する可能性が高く、経過観察でよいと考えられる。
