About this study

Official title: Manometry- Versus Symptom-Guided Large Volume Thoracentesis: a Randomized Controlled Study

This randomized controlled trial attempts to determine whether the measurement of pleural pressures during therapeutic thoracentesis affects the development of chest discomfort after the procedure. During thoracentesis, pleural fluid is drained from the pleural space, resulting in lung expansion. In some cases, the lung is not completely re-expandable, in which case continued drainage results in the development of negative pleural pressures and chest discomfort. Negative pleural pressures may also result in other complications such as re-expansion pulmonary edema and pneumothorax. The identification of negative pleural pressures via manometry during the procedure may lead to a reduction in the complication rate.

PRIMARY OBJECTIVES:

  1. To study the impact of pleural manometry on the development of chest discomfort during therapeutic thoracentesis compared to conventional symptom-guided thoracentesis.

OUTLINE: Patients are randomized to 1 of 2 treatment arms.

ARM I: Patients undergo manometry-guided therapeutic thoracentesis.

ARM II: Patients undergo symptom-guided thoracentesis.

Being tested
Manometry-guided thoracentesis, Symptom-guided thoracentesis
Medical subject headings
Pleural Effusion

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Manometry-guided thoracentesisOther

    Arm I will undergo a standard of care therapeutic thoracentesis procedure, and in addition include pleural pressure monitoring (via an FDA-approved digital manometer) which is also standard of care but left at the discretion of physicians as per expert recommendations. In this group, the procedure will be stopped when the patient develops symptoms or when all the fluid has been removed, and will also be stopped if the pressure begins to fall quickly in the fluid collection.

  • Symptom-guided thoracentesisOther

    Arm II will undergo a standard of care therapeutic thoracentesis procedure. In this group, the procedure but will be stopped when the patient develops symptoms or when all the fluid has been removed.

Study groups in NCT02677883
Study groupRoleWhat they receive
Arm I: Manometry-guided thoracentesisExperimentalIntervention Group - Patients undergo fine needle- aspiration, called therapeutic thoracentesis, to drain fluid accumulated around the lung. Unlike Arm II, the intervention group will have their pleural pressure monitored during the procedure.
Receives: Other: Manometry-guided thoracentesis; Other: Symptom-guided thoracentesis
Arm II: Symptom-guided thoracentesisActive comparatorComparison Group - Patients undergo symptom-guided thoracentesis, the current standard-of-care is to drain fluid until 1) it is all gone or 2) a symptom occurs that indicates the lung may take longer to fully re-expand and drainage should be stopped.
Receives: Other: Symptom-guided thoracentesis

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Difference in post-procedure chest discomfort scores between control (symptom-guided) and intervention (manometry-guided) groups

    As measured in millimeters along a 10 cm Visual Analog Scale (VAS). The estimated minimal clinically important difference is 15 mm. Descriptive statistics including means, standard deviations, and ranges will be presented. Investigations for outliers and assumptions for statistical analysis, e.g., normality and homoscedasticity will be made. If necessary, data will be transformed using Box-Cox power transformation. Comparisons between groups, i.e. intervention versus (vs) control, will be made using the t-test or Wilcoxon Rank Sum test. Mixed model will be employed to assess the trend of pain score measured across pre-, intra-, and post-procedure.

    Measured: one-time assessment, 5 minutes after thoracentesis catheter is removed (on day 1)

Secondary outcomes (8)
  1. Change in chest discomfort scores from pre-procedure to post-procedure.

    As measured in millimeters along a 10 cm Visual Analog Scale (VAS). Descriptive statistics including means, standard deviations, and ranges will be presented. Investigations for outliers and assumptions for statistical analysis, e.g., normality and homoscedasticity will be made. If necessary, data will be transformed using Box-Cox power transformation. Comparisons between groups, i.e. intervention versus (vs) control, will be made using the t-test or Wilcoxon Rank Sum test. Mixed model will be employed to assess the trend of pain score measured across pre-, intra-, and post-procedure.

    Measured: From 1 minute pre-procedure to 5 minutes after thoracentesis catheter is removed (on day 1)

  2. Incidence of complete lung re-expansion, as assessed by post-procedure chest radiograph

    Descriptive statistics including percentages and frequencies will be presented. Investigations for outliers and assumptions for statistical analysis, e.g., normality and homoscedasticity will be made. If necessary, data will be transformed using Box-Cox power transformation. Comparisons between groups, i.e. intervention vs control, will be made using the Chi-square test.

    Measured: 20 minutes after thoracentesis catheter is removed (on day 1)

  3. Duration of procedure

    Measured in seconds, assessed from the time the thoracentesis catheter is introduced to the time the catheter is removed. Descriptive statistics including means, standard deviations, and ranges will be presented. Investigations for outliers and assumptions for statistical analysis, e.g., normality and homoscedasticity will be made. If necessary, data will be transformed using Box-Cox power transformation. Comparisons between groups, i.e. intervention vs control, will be made using the t-test or Wilcoxon Rank Sum test.

    Measured: during the procedure, on day 1, intraoperative

  4. Change in subjective report of dyspnea

    Assessed in millimeters along a 10 cm Visual Analog Scale (VAS), from pre-procedure (baseline) to 5 minutes after completion of the procedure. Descriptive statistics including means, standard deviations, and ranges will be presented. Investigations for outliers and assumptions for statistical analysis, e.g., normality and homoscedasticity will be made. If necessary, data will be transformed using Box-Cox power transformation. Comparisons between groups, i.e. intervention vs control, will be made using either the t-test or Wilcoxon Rank Sum test.

    Measured: From 1 minute pre-procedure to 5 minutes after thoracentesis catheter is removed (on day 1)

  5. Incidence of clinically-significant re-expansion pulmonary edema

    Assessed as present if immediate post-procedure chest radiograph demonstrates new pulmonary edema per radiologist interpretation when compared to pre-procedure radiograph in the hemithorax that underwent thoracentesis, and subject has post-procedure new-onset or worsened hypoxic respiratory failure. Descriptive statistics including percentages and frequencies will be presented. Investigations for outliers and assumptions for statistical analysis, e.g., normality and homoscedasticity will be made. If necessary, data will be transformed using Box-Cox power transformation. Comparisons between groups, i.e. intervention vs control, will be made using the Chi-square test.

    Measured: 20 minutes after thoracentesis catheter is removed (on day 1)

  6. Incidence of pneumothorax

    Assessed as either present or absent on the immediate post-procedure chest radiograph per radiologist interpretation. Descriptive statistics including percentages and frequencies will be presented. Investigations for outliers and assumptions for statistical analysis, e.g., normality and homoscedasticity will be made. If necessary, data will be transformed using Box-Cox power transformation. Comparisons between groups, i.e. intervention vs control, will be made using the Chi-square test.

    Measured: 20 minutes after thoracentesis catheter is removed (on day 1)

  7. Incidence of radiographically-apparent re-expansion pulmonary edema

    Assessed as present if immediate post-procedure chest radiograph demonstrates new pulmonary edema per radiologist interpretation when compared to pre-procedure radiograph in the hemithorax that underwent thoracentesis. Descriptive statistics including percentages and frequencies will be presented. Investigations for outliers and assumptions for statistical analysis, e.g., normality and homoscedasticity will be made. If necessary, data will be transformed using Box-Cox power transformation. Comparisons between groups, i.e. intervention vs control, will be made using the Chi-square test

    Measured: 20 minutes after thoracentesis catheter is removed (on day 1)

  8. Volume of pleural fluid removed by the thoracentesis procedure

    Measured in milliliters. Descriptive statistics including means, standard deviations, and ranges will be presented. Investigations for outliers and assumptions for statistical analysis, e.g., normality and homoscedasticity will be made. If necessary, data will be transformed using Box-Cox power transformation. Comparisons between groups, i.e. intervention vs control, will be made using the t-test or Wilcoxon Rank Sum test.

    Measured: immediately after the thoracentesis catheter is removed, on day 1
