Clinical analysis of occurrence of pneumothorax in the application of central venous catheterization of pleural effusion

Abstract

Objective To explore the relationship of occurrence of pneumothorax between the pleural effusion and malignant pleura[ effusion from lung cancer. Methods One hundred and eighty-two cases of malignant pleura] effusion from lung cancer were selected as group one and 188 cases of tubereulous pleural effusion were selected as group two at the same time in the hospital, then central venous catheterization were clone in the two groups to drain the pleural effusion. X -ray was taken to observe whether the pneumothorax occurs or not before and after the drainage. Results Pneumotberax occurred in 17 cases of 182 malignant pleural effusion from lung cancer, 9.34 percent, and occurred in 2 cases of 188 cases of tuberculous pleura] effusion, 1.06 percent. According to sex, age and the occurrence of pneumothorax, logistic regression analysis was taken in the two groups. The results showed that the occurrence of pneumothorax was related to the disease category. The ratio of the two groups OR value was 0. 089, P < 0.05, 95% confidence interval was (0.011,0.854). Conclusions Malignant pleural effusion from lung cancer has more dangerous in the occurrence of pneumothorax during the course of puncture compared with the other pleural effusion. The reasonable explanation may be that in the basis of original lesion, the loss of protection and (or) the reduce of the intrathoracic pressure caused pneumothorax after the pleural effusion were drained.
