The goal of this observational study is to learn if saline results in improvement for patients with infection of their plerual space. The main question it aims to answer is:
What is the time to chest tube removal? Do these patients after need to escalate to fibrinolytics? Do these patients after need to escalate to surgery?
Participants will:
Patients who require a chest tube for complicated parapneumonic effusion or empyema who meet inclusion criteria and consent, will be enrolled. An ultrasound measurement of the original effusions prior to chest tube placement will be obtained then chest tube insertion will follow as well as an additional US measurement once placed. After appropriate positioning is confirmed, there will be instillation of intrapleural saline and will be administered every 8 hours for a total of 3 days. After completion of the intrapleural saline course, the effusion will be remeasured by ultrasound. Should the effusions fail to reduce by 75% or significant septations remain, the patient will then be escalated to intrapleural tPA/DNase which will be administered every 12 hours for 3 days. After the completed course of tPA/DNase, a US will be performed, and if significant fluid remains, >50% of the original effusion or septations remain, Thoracic Surgery consultation will be placed for discussion of VATs.

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| Intraplerual Saline | Other | All patients will be in a single arm and escalated from intraplerual saline to tPA/DNAse followed by surgery as warranted based on protocol criteria. |

| Name | Type | Description | Arm Group Labels | Other Names |
|---|---|---|---|---|
| Intrapleural Saline with possible escalation to intraplerual alteplase and dornase. | Drug | Though intraplerual alteplase/ dornase alfa and normal saline have been established method to reduce complicated pleural infection sizes and rate of surgical interventions, with tPA/DNAse being the gold standards, there has not been a study comparing the two head to head. This trial's purpose is to function as pilot study as a foundation for a potential noninferiorrity trail comparing the two. |
| Measure | Description | Time Frame |
|---|---|---|
| Time to chest tube removal | measuring the length of time from chest tube insertion to removal | From enrollment to removal- estimated up to 7 days. Once chest tube is placed, it will take 3 days for saline course to be completed and, if escalated, 3 days for intrapleural fibrinolytics, therefore may not be removed until after 7 days. |
| Measure | Description | Time Frame |
|---|---|---|
| Need for escalation to fibrinolytics | Rate of patients requiring intraplerual tPA/DNAse after completion of intrapleural saline | From enrollment to chest tube removal- up to 7 days. Once chest tube is placed, it will take 3 days for saline course to be completed and, if escalated, 3 days for intrapleural fibrinolytics, therefore may not be removed until after 7 days. |
