Abstract

The composition of gases and the gas tension in middle ear effusion in patients with serous otitis media have been investigated. By using a specially designed micro-method, very small amounts of middle ear fluid could be analyzed. The effusion was obtained by puncturing the air cells of the mastoid process. The average value of P-O2 was 41 mm Hg; Pco2 was 58 mm Hg, pH 7.24. The possible mechanism for the impaired perfusion of the mucous membranes is discussed as well as some clinical consequences.

摘要

对浆液性中耳炎患者中耳积液中的气体成分和气体张力进行了研究。通过使用一种专门设计的微量方法，可以分析极少量的中耳液。积液是通过穿刺乳突气房获得的。氧分压（P-O2）的平均值为41毫米汞柱；二氧化碳分压（Pco2）为58毫米汞柱，pH值为7.24。文中讨论了黏膜灌注受损的可能机制以及一些临床后果。
