简要总结
Malignant pleural effusion remains a debilitating complication of end stage cancer, which can be greatly improved by the introduction of the indwelling tunneled pleural catheter (IPC). However, there is no standard of care regarding drainage and limited data on the utility of different drainage techniques. In addition, many patients develop discomfort and chest pain during drainage. The investigators propose to evaluate gravity drainage and suction drainage on quality of life measures and outcomes.
详细描述
Indwelling tunneled pleural catheters (IPCs) are used to alleviate pleural effusion as a first-line therapeutic (albeit palliative) intervention. Limited data currently exists on drainage techniques and the impact the techniques may have on quality of life. Current recommendations for IPC drainage range from daily drainage to once a week drainage, as well as only when needed for dyspnea. It has been theorized that active drainage of effusions may have an impact on the development of chest discomfort/pain, whereas passive regimens may allow for more gradual intrathoracic pleural changes and potentially offer a difference in drainage discomfort.
The objective of this investigation is to compare different drainage strategies of indwelling pleural catheters (IPCs) regarding patient quality of life and outcomes. Patients will undergo placement of a pleural catheter as per standard institutional protocol. Patients will be randomized on a 1:1 basis into the suction drainage (active) arm or the gravity drainage (passive) arm. Patients will receive follow-up at two weeks, four weeks, twelve weeks and then as needed post IPC placement per standard clinical protocol. All patients will be asked to fill out quality of life questionnaires and update drainage diary information with patient's providers.
Patients will undergo standard care treatment throughout the disease course and no different interventions regarding the pleural disease will be performed as a result of enrollment within this study. Study interventions/procedures will consist of questionnaires and patient self-reported documentation regarding patient's care and outcomes.

入选标准
- •Clinical indications for placement of IPC for malignant pleural effusion
- •a. Pleural effusion with symptomatic improvement in dyspnea after drainage of ipsilateral effusion
- •Clinically confident symptomatic malignant pleural effusion
- •Histocytological proof of pleural malignancy
- •Recurrent large pleural effusion in context of histologically proven cancer outside the pleural space
- •Plans for placement of IPC within ten days of enrollment
- •Age > 17 years

排除标准
- •Recent (less than 60 days) thoracic surgery or chest trauma causing chronic pain
- •Pregnant or lactating mothers
- •Previous ipsilateral chemical pleurodesis

- •Known rib or thoracic skeletal metastasis causing pain
- •Concern for active pleural infection
- •Respiratory failure
- •Irreversible bleeding diathesis

研究组 & 干预措施
Vacuum
The pleural fluid will be drained by the syringe system with a one-way valve tubing system provided in the kit. Selection of the vacuum pressure will be at the discretion of the proceduralist, as per standard of care. Participants in this arm will undergo Vacuum-Based IPC.
干预措施: Vacuum-Based IPC (Procedure)
Gravity
The pleural fluid will be drained using gravity drainage to a bag positioned at bedside. Participants in this arm will undergo Gravity-Based IPC.
干预措施: Gravity-Based IPC (Procedure)
结局指标
主要结局
Change in chest pain as assessed by Visual Analog Scale (VAS)
时间窗: Daily, up to 2 weeks
The primary endpoint is the difference between the mean daily change in pain score during IPC drainage via the vacuum bottle technique and IPC drainage via the gravity bag technique over two weeks after IPC placement. Pre-drainage and post-drainage pain scores will be recorded each day of IPC placement. Measurements are in millimeters along a 10 cm VAS. VAS score is a range of 0 to 100. Lower limit is 0, meaning no pain; upper limit is 100, meaning extreme pain.
次要结局
- Change in Functional Assessment of Chronic Illness Therapy (FACIT)-Dyspnea survey score(pre-IPC placement, 12 weeks post IPC placement or time of pleurodesis)
- Change in mean difference in chest pain as assessed by VAS(pre-IPC placement, 12 weeks post IPC placement or time of pleurodesis)
- Change in SF 36-Item Health Survey score(pre-IPC placement, 12 weeks post IPC placement or time of pleurodesis)
