Title: Locating the bronchus of air leakage air ingestion and pressure measurement through Swan-Ganz catheter in patient with pneumothorax
Abstract: Objective To evaluate the efficacy and safety of a new method to locate the bronchus of pulmonary air leakage by gas ingestion and pressure measurement through Swan-Ganz catheter tampond. Methods Forty-four cases with pneumothorax were randomly divided into two groups. Group A:in which the balloon of the Swan-Ganz catheter was filled with physiological saline and blocked air flow of target bronchus to detect the broken bronchus of pneumothorax patients. Group B:for patients in Group A, injecting air via the catheter and measuring the intra-bronchial pressure in the front of the balloon. Results In Group B, the success rate of closure of air leakage was 91%(10/11), better than that in Group A 50%(5/10) (P 0.05), and there was no significant difference between the two groups in open and tension pneumothorax (P 0.05). In Group A, the mean time of locating was (12±3.4) min, and that in Group B was (14±3.1) min (P 0.05). Patients in both groups were well tolerated without any obvious adverse effects. Conclusions It is safe and accurate to locate the bronchus of pulmonary air leakage by air ingestion and pressure measurement through Swan-Ganz catheter. This intervention is particularly suitable for patients who had performed chest negative pressure drainage, but no remarkable gas could be seen in the drainage tube.
