随着血液pH、气体分析的临床广泛应用,胸水的pH测定已引起了临床和实验室的重视。为了探讨pH对胸水鉴别诊断的价值,我们测定了102例胸水的pH值,并同时与自身动脉血pH进行比较。 一、对象和方法 1.测定对象 102例均选自本院门诊或住院未经治疗的患者,癌性胸水36例,男21例,女15例。年龄为20～81岁,平均53岁。病例选择标准:经痰或胸水细胞学检查、胸膜活检、纤维支气管镜下活检、淋巴结活检、肺切除标本病理学证实等一项以上检查确诊为肺癌者。结核性胸水66例,男39例,女27例。年龄18～79岁,平均51岁。病例选择标准:(1)痰或胸水涂片或培养抗酸杆菌阳性;(2)有结核病临床表现并除外其它疾患引起的胸腔积液;(3)胸膜活检发现结核结节。
With the wide application of blood pH and gas analysis, pH measurement of pleural effusion has attracted clinical and laboratory attention. In order to investigate the value of pH in the differential diagnosis of pleural effusion, we measured the pH of 102 pleural effusions and compared them with the arterial blood pH. First, the object and method 1. Determination of 102 cases were selected from our hospital or hospitalized untreated patients, 36 cases of cancerous pleural effusion, 21 males and 15 females. Age is 20 to 81 years old, average 53 years old. Case selection criteria: sputum or pleural fluid cytology, pleural biopsy, fibrobronchial biopsy, lymph node biopsy, lung resection specimens confirmed by pathology confirmed more than one lung cancer. 66 cases of tuberculous pleural effusion, 39 males and 27 females. Age 18 to 79 years old, average 51 years old. Case selection criteria: (1) sputum or pleural effusion smear or culture of acid-fast bacilli positive; (2) tuberculous clinical manifestations and other diseases caused by pleural effusion; (3) pleural biopsy found tuberculosis nodules.
