为了给哮喘病人提供合适的治疗,医生必须了解患者气道阻塞的严重程度。但在临床上医生用以判断气道阻塞之方法的价值是有限的。这些方法包括喘息和呼吸窘迫的症状、体征、辅助呼吸肌收缩及奇脉等。McFadden等认为以体征作为判断哮喘病人的气道阻塞程度是不够的,因为气道阻塞已相当严重的病人,体检却可无任何异常发现。作者对35例住院和门诊哮喘病人及61例有气道阻塞倾向的患者,作了最大呼气流速(PEFR)测定。并把病人自我判断气道阻塞的程度与有经验医生的判断进行比较。其结果表明:有经验的病人判断自己的PEFR(准确率63%),比医生的判断(准确率44%)更准确。病人能够相当准确地判断自己气道阻塞是否好转、稳定或恶化。但病人自己判断哮喘严重度的能力,尚未被临床
To provide proper treatment to asthmatic patients, the doctor must understand the severity of the patient’s airway obstruction. However, the value of clinically used methods for determining airway obstruction is limited. These include wheezing and respiratory distress symptoms, signs, accessory respiratory muscle contractions and odd veins. McFadden so that signs of asthma as a judge of the degree of airway obstruction is not enough, because the airway obstruction has been very serious in patients, physical examination but without any abnormal findings. The authors performed maximum expiratory flow rate (PEFR) measurements on 35 patients with inpatient and outpatient asthma and 61 patients with airway obstruction. The patient’s self-judgment of airway obstruction was compared with that of experienced doctors. The results showed that: Experienced patients to determine their own PEFR (accuracy 63%), more than the doctor’s judgment (accuracy 44%) more accurate. The patient can fairly accurately determine whether his airway obstruction improves, stabilizes, or worsens. However, the patient’s own ability to judge the severity of asthma has not been clinically
