Brief Summary

Transudative pleural effusions are a common manifestation of patients with congestive heart failure. Severe dyspnea and respiratory failure may develop in those with large effusions, which in general show poor response to medical treatment. Therapeutic thoracenteses (TT) may be indicated in these patients and can produce marked relief of symptoms. However, the underlying effect of TT on gas exchange and respiratory mechanics in theses patients remains unclear. The researchers' hypothesis is that,TT may improve arterial oxygenation and respiratory mechanics in patients with congestive heart failure complicated by large pleural effusions.

Outcome Measures

Primary Outcomes (1)

  • Vital signs, minute volume, expiratory tidal volume, dynamic compliance, arterial oxygen saturation and arterial blood gases, the volume of pleural fluid removed, and the changes in pleural liquid pressure and pleural space elastance

    15 minutes after therapeutic thoracentesis

Interventions

Thoracentesis was performed with drainage of 500 ml of pleural fluid first and every 200 ml thereafter until pleural pressure was lower than -20 cm H2O, chest discomfort developed, or no more pleural fluid could be removed.
