Model of pleural fluid turnover

Journal of Applied Physiology, 1993
A model of pleural fluid turnover, based on mass conservation law, was developed from experimental evidence that 1) pleural fluid filters through the parietal pleura and is drained by parietal lymphatics and 2) lymph flow increases after an increase in pleural liquid volume, attaining a maximum value 10 times greater than control.

Pleural fluid characteristics of tuberculous pleural effusions

Heart & Lung, 2010
Mycobacterium tuberculosis (TB) infection of the pleural space is an important cause of pleural effusion in areas of high TB prevalence. Microbiological analyses of pleural fluid in the acute setting may be negative. Consequently, investigations may proceed to more invasive techniques, such as pleural biopsy or thoracoscopy. Ongoing research has led to

Pleural Fluid Analysis in Chylous Pleural Effusion

Chest, 2008
Chyle is a noninflammatory, lymphocyte-predominant fluid that may cause a pleural effusion as a consequence of thoracic duct leakage into the pleural space. Although chyle is reported to have protein concentrations in the transudative range, chylous effusions are typically exudative, as defined by the standard criteria.

Observations on pleural fluid pressures as fluid is withdrawn during thoracentesis.

American Review of Respiratory Disease, 2015
In 52 patients with pleural effusions, pleural pressures were measured initially and serially as pleural fluid was withdrawn. Pleural fluid aspiration was continued until the pleural pressure fell below -20 cmH2O, or the patient developed excessive ...

Pleural Lymphatics as Regulators of Pleural Fluid Dynamics

Physiology, 1991
Pleural fluid is filtered across the parietal mesothelium in the top of the pleural cavity and removed by lymphatic stomatas in the more dependent mediastinal and diaphragmatic regions. The pleural lymphatics act as a feedback system that regulates pleural liquid volume and its protein composition around a low volume set point.

Aspiration of Pleural Fluid

Diseases of the Chest, 1950
1) A change in the routine manner of positioning the patient from the vertical or sitting to the lateral recumbent method of approach is proposed. 2) The lateral recumbent position for doing a chest tap, with the fluid side dependent, has safety, completeness, speed and convenience. 3) By placing the patient in the lateral recumbent position,

Pleural-fluid kinetics in a patient with primary lymphedema, pleural effusions, and yellow nails.

American Review of Respiratory Disease, 2015
We present the clinical findings in the thirteenth recorded patient with lymphedema, pleural effusions, and ungual dystrophy--the so-called "yellow nail" syndrome.

Penetration of Ciprofloxacin into Pleural Fluid

Journal of Chemotherapy, 1993
The penetration of oral 1000 mg/day ciprofloxacin into pleural fluid is investigated in 15 patients with exudative pleural effusion. After 4 days of ciprofloxacin therapy ciprofloxacin concentrations were measured in plasma and pleural exudate simultaneously by high-performance liquid chromatography (HPLC). Mean serum ciprofloxacin level was 1.58 +/- 0.

Masquerade With Mediastinal Pleural Fluid

JAMA: The Journal of the American Medical Association, 1975
A TRIANGULAR density in the right paraspinal area has been considered as evidence of right lower lobe atelectasis. 1-3 Fluid density merging with the right margin of the heart may be interpreted as an enlarging heart. 4 Finally, with known disease of the right lower lobe, a subsequent increase in density off the right margin of the heart may suggest ...

Pleural fluid exchange in rabbits

Respirology, 2007
Background and objectives:  The study was designed to better characterize pleural fluid absorption in rabbits with the following two objectives: to determine the relative absorption of saline versus high‐protein solutions, and to identify the relative rates of absorption of dextran molecules of varying sizes.Methods:  Twenty New Zealand white rabbits ...
