[Surgical treatment and classification of spontaneous pneumothorax caused by break-up of bullae].
To explore the appropriate operation for surgical treatment and a better classification for spontaneous pneumothorax caused by break-up of bullae. ⋯ The clinical classification was thought to be valuable for diagnosis and treatment of spontaneous pneumothorax caused by break-up of bullae.

[Application of bedside monitoring with arterized capillary blood, transcutaneous and end tidal carbon dioxide during mechanical ventilation].
Arterial blood, arterialized capillary blood, transcutaneous, end tidal carbon dioxide pressure (PaCO2, PcCO2, PtcCO2, PetCO2) and physiological respiratory deadspace to tidal volume ratio (VD/VT) were observed in 12 patients with chronic obstructive pulmonary disease (group A), 17 postoperative patients of cardiac surgery (group B), and 16 healthy subjects (group C) under three mechanical ventilatory patterns. PcCO2, PtcCO2 and PetCO2 were found to correlate well with PaCO2 (r = 0.99, 0.97 and 0.88 respectively); P(a-et) CO2 correlated with age (year) in group B and C (r = 0.77 and 0.76), and all P(a-et) CO2 measurements of each of three groups highly correlated with VD/VT (r = 0.96 0.91 and 0.87 for group A,B,C respectively). The results suggested that the trend of PaCO2 variation can be deduced from PcCO2, PtcCO2 and PetCO2 with fair accuracy under various ventilatory patterns in subjects with stable circulatory function, and P(a-et) CO2 is a simple quantitative index for evaluating physiological deadspace.

[Facial or nasal mask pressure support ventilation in managing acute exacerbation of chronic respiratory failure in chronic obstructive pulmonary diseases].
11 COPD patients (age: 65 +/- 9 Yrs) with acute exacerbation of chronic respiratory failure (PaCO2 11.3 +/- 1.1kPa) were treated with mask pressure support ventilation, another 10 similar patients (age: 68 +/- 12 Yrs) served as control. BiPAP ventilator was used with the following modifications: (1) Non-rebreathing valve set-in proximal to mask; (2) 5 LPM oxygen flow delivered into mask to reduce the dead space effect. ⋯ Synchrony and airway patency were specially monitored. The results suggested that mask ventilation could reduce PaCO2, improve PaO2, relieve dyspnea and decrease the possibility of intubation.

[Pulmonary artery pressure estimated by Doppler echocardiography in patients with chronic obstructive pulmonary disease].
Doppler echocardiography and right heart catheterization were performed in 18 patients with COPD. The pulmonary blood flow pattern were analysed by the pulsed doppler flowmeter. ⋯ PG correlated well with sPAP (r = 0.89, P less than 0.001) and mPAP (r = 0.92, P less than 0.001). We considered that doppler echocardiography was useful for noninvasive estimation of pulmonary artery pressure in patients with COPD.

[Application of thoracoscopy in the diagnosis of pleuro-pulmonary disease].
Thoracoscopic examination was performed in 20 cases of pleuro-pulmonary diseases of uncertain etiology, 16 patients (80%) obtained positive thoracoscopic biopsy results while 4 false negative. Needle pleural biopsy was carried out in 10 cases and four of them gave correct diagnosis. ⋯ Thirteen cases with advanced tumor or benign pleural diseases were treated conservatively. It was concluded that thoracoscopy is as an important technique in diagnosis of pleuro-pulmonary diseases.
