换季“咳”不停,竟是这几点在作怪!预防春咳,看这篇就够了→
  2024/04/02| 阅读次数:1596

春天到来,万物复苏,处处都是美景。但是对于一部分人来说,“春光”可没有那么美好:一到换季,嗓子就总不舒服,到处都是咳声一片,还反反复复好不利索。究竟是什么病因呢?

换季“咳”不停,什么在作怪?

咳嗽本身不是疾病,是一种正常的生理反射,也是很多疾病常见的、共有的症状。作为就医最常见的主诉,在国内专科门诊中,咳嗽患者约占三分之一以上。现在正值换季,刚好是咳嗽患者大幅度增加的时节。


既然咳嗽不是病,那是什么原因导致了咳嗽呢?


01

过敏

春季空气中飘浮的花粉、尘埃,都是吸入性过敏原,种类多、密度高、数量大。临床上因为过敏导致的咳嗽主要是咳嗽变异性哮喘。它存在气道高反应性,咳嗽是其唯一或主要临床表现,以夜间咳嗽和干咳为主。

气温忽冷忽热

春季冷暖空气交替、昼夜温差大,容易出现呼吸道黏膜的不适和损伤,进而诱发咳嗽。


02
03

呼吸道感染后咳嗽

换季时很容易感染呼吸系统疾病,如普通感冒、急性气管-支气管炎,此时发生的咳嗽多为急性咳嗽。

当呼吸道感染的急性期症状消失后,仍会存在“感冒后咳嗽”,多表现为刺激性干咳或咳少量白色黏液痰,通常持续时间较长,一般情况下能自行缓解,但也有人发展成慢性咳嗽。

基础病诱发慢性咳嗽

老年人往往存在慢性支气管炎、肺气肿、支气管扩张、慢性咽炎等多种基础病,也导致咳嗽病因较为复杂,咳嗽迁延不愈。

目前认为咳嗽时间持续≥8周以上,X线胸片无明显肺部疾病证据的咳嗽就是慢性咳嗽。


04



止咳药,很多人都用不对!

在我国,止咳药可以说是家家必备的常用药,不正确的用法也很常见:


  • 刚咳嗽就服药


有些人一咳嗽就紧张,想吃点止咳药。咳嗽是一种自我保护机制,能有助于清除呼吸道中的异物、分泌物。如果刚咳嗽就用药“镇”住了,分泌物和病原体没有通过咳嗽排出,可能引起气道堵塞和继发细菌感染。


所以咳嗽时并不是要急于止咳,而是去分析究竟是什么病因,再根据症状酌情用药。


  • 用不对药


前面提到过,咳嗽的病因很多,针对不同疾病用药也不同。但实际生活中,有很多人胡乱用药。


比方说咳嗽是抗菌药物滥用的重灾区。但绝大部分的上呼吸道急性感染都是病毒引起的,使用抗生素非但没有用,反而加重耐药性。


  • 滥用中枢性止咳药


不建议使用含有可待因的中枢性镇咳药物,可待因属于阿片类镇咳药,具有一定成瘾性,会导致药物依赖性,对身体造成不良影响。


如何正确使用止咳药物?


如果咳嗽伴有痰,特别是痰粘不易咳出,可以使用氨溴索。


氨溴索属于化痰药物,能够有效保护患者呼吸系统,对肺部疾病、气管疾病临床效果显著。需要注意的是,它要避免与中枢性强效止咳药可待因、右美沙芬等合用。


如果不伴有痰,可以选择一些止咳药,比如右美沙芬等。

如果合并咳喘,可以应用解痉平喘药物,如复方甲氧那敏、孟鲁司特钠等。

如果咳嗽时间长,伴有呼吸困难、呼吸急促、喘息等症状,有过敏和哮喘病史,影响生活和精神状态,或者咳血痰、黑痰,请尽快去就医!






防治换季咳嗽,这样做

01



减少与过敏原接触

尽量避免接触已知过敏原。减少户外活动,出门佩戴口罩,减少吸入过敏原的机会。回家后及时更换衣物,防止把过敏原带入家中。


02



保持环境卫生

保持居家环境卫生,避免尘螨、霉菌滋生。勤换枕套被套等床上用品,并保持室内通风,减少湿度。尤其是空调和空气净化器容易成为卫生死角,记得定期清洗,确保室内空气质量。


03



换季饮食调理

饮食中应避免食用辛辣刺激性食物、海鲜和易过敏食物,选择清淡的烹饪方式,防止刺激呼吸道。多吃新鲜果蔬,增加维生素C的摄入,可以增强免疫力,减少过敏反应。


04



加强身体锻炼

运动可以增强身体免疫力,改善肺功能。但要注意运动要循序渐进,选择空气新鲜、安全的公园等场景。


05



合理使用药物

对于有哮喘、慢性咳嗽等病史的患者,建议按照医生的建议合理使用雾化器、吸入类药物等,提前预防和控制咳嗽的发作。
