About this study

Official title: Vacuum vs Manual Drainage During Unilateral Thoracentesis: A Randomized Trial

The purpose of this study is to determine if there are any differences in terms of safety, pain, or drainage speed between thoracenteses via manual drainage vs vacuum suction.

Read the detailed description

Patients with pleural effusions routinely undergo thoracentesis in which a catheter is placed into the pleural space to remove the fluid both for diagnostic and therapeutic reasons. In this setting, large amounts (often liters) of fluid are removed to palliate the patient's symptoms of breathlessness.

Thoracentesis is the most commonly performed and least invasive method to remove pleural fluid. These frequently performed using a catheter drainage system where a small, flexible temporary catheter is inserted over a needle into the pleural cavity. After insertion of catheter into the pleural space, the operator has two drainage system options: 1. Manual drainage via syringe-pump that connects to drainage bag or 2. Drainage into a vacuum bottle. Both are routinely performed in almost every hospital in the United States.

Pleural pressure (Ppl) is determined by the elastic recoil properties of the lung and chest wall. Normal pleural pressure is estimated to be -3 to -5 cm H20 at functional residual capacity. During drainage of pleural fluid, negative pressure is applied either via syringe during manual drainage or via vacuum using vacuum drainage bottle. Hypothetically more negative pressure can translate to increased perception of pain or visceral pleural injury.

Two techniques (manual vs vacuum drainage) are used based on the operator preference and both are standard of care. To our knowledge there is no head to head comparison of these two available systems of drainages during thoracentesis of pleural effusions. Knowing if one is superior to the other will aid future clinicians.

What is being measured

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

  1. Pain Change

    Difference in pain between pre-procedural pain and during drainage pain as measured as the difference between a pre-procedural NPSS pain score (range from 0 (no pain) to 10 (maximum pain)). This was asked again during drainage and the difference between the two was recorded. The values ranged from -10 to 10 (with a more negative number representing a decrease in pain and a more positive number representing an increase in pain)

    The scale used is called The Numeric Pain Rating Scale. With ratings from 0-10. Zero is the least amount of pain experienced while 10 is the worst pain possible.

    Measured: 5-20 minutes

Secondary outcomes (6)
  1. Time of Drainage

    Actual time of drainage in seconds for each patient.

    Measured: 5-20 minutes

  2. Number of Patients Who Had an Early Termination of Procedure

    Patients who had procedure termination prior to complete evacuation of the pleural contents (usually as a result of refractory pain or another symptom that the patient perceived).

    Measured: 5-20 minutes

  3. Number of Patients Who Had a Complication as a Result of the Procedure

    Any complications that occur as a direct result of the procedure. We tracked patients for 7 days after the procedure to capture any complications (which is typical clinical practice)

    Measured: <7 days

  4. Etiology of Effusion

    Clinical etiology of effusion

    Measured: <7 days

  5. Volume of Effusion

    Volume of effusion drained (in mL)

    Measured: <20 minutes

  6. Laterality of Effusion

    Laterality of effusion (left or right)

    Measured: <20 minutes
