PURPOSE: To describe the correlation of three pleural-manometry procedures and pleural space elastance in patients with pleural effusion.
METHODS: A descriptive study was conducted during May-October 2008 on a basis of 18 patients with pleural effusion undergoing 22 thoracenteses with one of three pleural-manometry procedures, which are 1) a simple water column manometry (U-shape water manometry), 2) interposal of a 22-gauge needle for water manometry and 3) a hemodynamic transducer. Pleural pressures were methodically measured at different paces; after removing 5 ml. of pleural effusion, every 500 ml. for 2 times, every 250 ml. for 4 times, and every 100 ml, respectively, until complications or pleural space elastance of more than 16 cmH2O/L developed.
RESULTS: All 18 patients’ known diagnoses were recorded with an amount of pleural effusion and pleural pressures for calculating the pleural space elastance. The recorded complications were cough, chest discomfort, blood pressure drop and oxygen desaturation. The pleural space elastance ranged from 4.5 to 36 cmH2O/L of U-loop procedures, 4.7 to 32 cmH2O/L of interposing a 22-gauge needle procedure, and 3.8 to 32.64 cmH2O/L from a hemodynamic transducer. The correlation of 3 pleural manometry procedures had a significant value (p< 0.001). No studied patient has suffered from a blood pressure drop. The range of pleural fluid removal was 250-2,100 ml.
CONCLUSION: The use of any of these three pleural-manometry procedures was associated with a clinical benefit in evaluating and managing pleural effusion.
CLINICAL IMPLICATIONS: The use of any of these three pleural-manometry procedures was associated with a clinical benefit in evaluating and managing pleural effusion.
