摘要
目的 总结分析 1996～ 2 0 0 2年间在北京协和医院诊断的 34例少年儿童非器质性呼吸困难病例。方法 非器质性呼吸困难的临床诊断标准 :有突出的呼吸困难 ,经过询问病史、体格检查和相关的实验室检查 ,没有心肺或其他器质性病因。结果 少年儿童非器质性呼吸困难最小发病年龄 8岁 ,13～ 16岁为高峰发病年龄 ,17岁以后发病人数明显减少。大多数为慢性病程 ,伴症状急性发作。表现为呼吸困难 ,伴随明显的过度通气、低碳酸血症的症状。少年儿童患者焦虑不明显 ,与成人形成鲜明对比。多数患儿有明显的心因性诱因 ,中学阶段学习压力大为最重要的诱因。 13例患儿接受腹式呼吸训练治疗 2～ 3个月后复查 ,呼吸困难和伴随症状得到明显改善。结论 少年儿童非器质性呼吸困难呈慢性过程 ,需要引起足够的重视 ,提高医师警觉性是正确诊断处理的关键。
Objective Medically unexplained dyspnea is common in adult and accounts for 14% patients complaining of dyspnea. Its occurrence in children is seldom recognized. In the present paper, 34 children with medically unexplained dyspnea (age 10 to 18 years) seen in Peking Union Medical College Hospital from 1996 to 2002 are reported. Methods The diagnosis of medically unexplained dyspnea was clinical: it was based on the presence of dyspnea and other complaints which cannot be explained by an organic disease. The patients answered Nijmegen questionnaire and state and trait anxiety (STAI), and performed hyperventilation provocation test. Twenty sessions of breathing therapy were applied and 13 out of 34 children were followed up after the therapy. Results Among the children, 75% started to have symptoms at the age of 13 to 16 years, though the age of first episode could be as early as 8 years. In most of the cases, the course was chronic clinically. In addition to marked dyspnea, their clinical profile included symptoms of hyperventilation i.e. blurred vision, dizziness, tingling, stiff fingers or arm. The symptoms of anxiety were less frequent in children and accordingly the level of anxiety evaluated by means of STAI was lower in children compared to adult patients. The precipitating psychological factors appeared to be related to middle school competition. Pressure from exams, reprimand from stern and unsympathetic teachers coupled with high parental expectation could be emotionally damaging to psychologically susceptible children. Thirteen patients were followed up after 2 3 months of breathing therapy with emphasis on abdominal breathing and slowing down of expiration. After therapy, the sum score of the Nijmegen Questionnaire was markedly decreased. Dyspnea and symptoms of hyperventilation were improved. The level of anxiety was minimally modified.Conclusion The cases illustrated the need for careful diagnostic evaluation and treatment because of the high rate of chronicity of the disorder.
