## Statements

- Ultrasound has no disadvantage compared to CT for diagnosing empyema and identifying pleural stranding, and prospective studies show that placing ultrasound before CT decreases CT utilization without changing outcomes. — Shawn St. Peter (clinical) [Ep 3 · 15:16](https://qa.library.globalcastmd.com/watch/empyema-with-dr-shawn-st-peter-312?t=916)

- When pleural fluid has >10,000 white cells and the patient undergoes VATS, the pleural space appearance is consistent with typical empyema. — Shawn St. Peter (clinical) [Ep 3 · 7:02](https://qa.library.globalcastmd.com/watch/empyema-with-dr-shawn-st-peter-312?t=422)
- The randomized trial at Children's Mercy compared primary VATS to primary fibrinolysis and found no difference in length of stay, with a 16% failure rate in the fibrinolysis group. — Shawn St. Peter (clinical) [Ep 3 · 7:39](https://qa.library.globalcastmd.com/watch/empyema-with-dr-shawn-st-peter-312?t=459)
- Great Ormond Street published a study of 60 patients using urokinase with 4-hour dwell time that found identical results: no difference in length of stay and a 1 in 6 (approximately 16%) failure rate. — Shawn St. Peter (clinical) [Ep 3 · 17:34](https://qa.library.globalcastmd.com/watch/empyema-with-dr-shawn-st-peter-312?t=1054)
- A Spanish randomized trial of 100 patients using urokinase found no difference in length of stay and a 15% failure rate, consistent with prior studies. — Shawn St. Peter (clinical) [Ep 3 · 19:14](https://qa.library.globalcastmd.com/watch/empyema-with-dr-shawn-st-peter-312?t=1154)

- In 100 consecutive patients treated with fibrinolysis after the trial, there was no difference in operative time or blood loss for patients who required subsequent VATS compared to primary VATS, contradicting concerns that fibrinolysis makes subsequent surgery more difficult. — Shawn St. Peter (clinical) [Ep 3 · 19:14](https://qa.library.globalcastmd.com/watch/empyema-with-dr-shawn-st-peter-312?t=1154)

- A second round of fibrinolysis is only indicated when imaging shows a walled-off collection not in continuity with the initial chest tube placement; if the tube is well-positioned and there is persistent pleural disease in continuity with the tube, a second round is not recommended. — Shawn St. Peter (clinical) [Ep 3 · 26:42](https://qa.library.globalcastmd.com/watch/empyema-with-dr-shawn-st-peter-312?t=1602)

- Recurrent empyema after successful treatment is extremely rare because the pleural space is typically obliterated (cemented space), making randomized trials of antibiotic duration unfeasible due to zero event rate. — Shawn St. Peter (clinical) [Ep 3 · 13:00](https://qa.library.globalcastmd.com/watch/empyema-with-dr-shawn-st-peter-312?t=780)
- In the United States, TPA is the only available fibrinolytic agent for empyema since urokinase is not available and streptokinase has come off the market. — Shawn St. Peter (clinical) [Ep 3 · 34:27](https://qa.library.globalcastmd.com/watch/empyema-with-dr-shawn-st-peter-312?t=2067)

- Mary Anne Jackson, an infectious disease physician, recommended the >10,000 white cell entry criterion for the trial, which initially seemed too soft but proved completely correct. — Shawn St. Peter (clinical) [Ep 3 · 4:40](https://qa.library.globalcastmd.com/watch/empyema-with-dr-shawn-st-peter-312?t=280)
- When comparing an operation to a non-operative approach, if results are equal, there is no way to recommend the operation and no parent would choose surgery when outcomes are the same. — Shawn St. Peter (opinion) [Ep 3 · 18:20](https://qa.library.globalcastmd.com/watch/empyema-with-dr-shawn-st-peter-312?t=1100)

- Necrotic lung heals remarkably well without surgical intervention, as demonstrated by a patient with no viable lung on either side after two weeks of ECMO who left the hospital without oxygen. — Shawn St. Peter (clinical) [Ep 1 · 33:57](https://qa.library.globalcastmd.com/watch/empyema-with-dr-shawn-st-peter-932?t=2037)
- A well-defined peripheral pulmonary abscess can be drained if it is well out into the lung parenchyma with a thick rind, ensuring you are getting into abscess and not airway. — Shawn St. Peter (clinical) [Ep 1 · 32:54](https://qa.library.globalcastmd.com/watch/empyema-with-dr-shawn-st-peter-932?t=1974)
- Multifocal abscesses and complex abscesses can be treated like necrosis by being patient, and even fields of abscesses in patients with underlying disease will typically heal up. — Shawn St. Peter (clinical) [Ep 1 · 32:20](https://qa.library.globalcastmd.com/watch/empyema-with-dr-shawn-st-peter-932?t=1940)
- Chest tube alone for empyema is not adequate treatment. — Shawn St. Peter (clinical) [Ep 1 · 11:09](https://qa.library.globalcastmd.com/watch/empyema-with-dr-shawn-st-peter-932?t=669)
- Chest X-rays after completing fibrinolysis are not terribly useful because they will look pretty bad for quite a while and are not helpful in discerning whether a patient is a candidate for VATS after failed fibrinolysis. — Shawn St. Peter (clinical) [Ep 1 · 23:25](https://qa.library.globalcastmd.com/watch/empyema-with-dr-shawn-st-peter-932?t=1405)
- Available fibrinolytic agents worldwide are urokinase or TPA, and since urokinase is not available in the US after streptokinase came off the market, TPA is the only option in the United States. — Shawn St. Peter (clinical) [Ep 1 · 34:27](https://qa.library.globalcastmd.com/watch/empyema-with-dr-shawn-st-peter-932?t=2067)
- For older children, chest tube placement can be done with local anesthetic injection alone without sedation, as it can be completed in less than a minute. — Shawn St. Peter (clinical) [Ep 1 · 22:40](https://qa.library.globalcastmd.com/watch/empyema-with-dr-shawn-st-peter-932?t=1360)
- When sedation is required for chest tube placement, it can be done in the operating room without intubation or positive pressure ventilation using a needle-guided 12-French chest tube, which is less involved than placing a PICC line. — Shawn St. Peter (clinical) [Ep 1 · 21:40](https://qa.library.globalcastmd.com/watch/empyema-with-dr-shawn-st-peter-932?t=1300)
- Performing limited debridement with VATS when general anesthesia is required nullifies some advantages of fibrinolysis because mechanical debridement kicks up the serum response and positive pressure ventilation affects the other lung. — Shawn St. Peter (opinion) [Ep 1 · 21:06](https://qa.library.globalcastmd.com/watch/empyema-with-dr-shawn-st-peter-932?t=1266)

## Host summaries
Recaps by a host of what the experts said — not the host's own clinical position.
- The IDSA community-acquired pneumonia guidelines recommend 10 days of antibiotics after becoming afebrile, but this is a grade D recommendation based on no data. — Shawn St. Peter summarizing a resource [Ep 3 · 11:20](https://qa.library.globalcastmd.com/watch/empyema-with-dr-shawn-st-peter-312?t=680)
- Ted Carter and colleagues from Seattle proposed an algorithm for pleural effusions categorizing them as small (<25%), moderate (25-50%), or large (>50%), with symptomatic versus asymptomatic branches under each category. — Shawn St. Peter summarizing a resource [Ep 3 · 5:10](https://qa.library.globalcastmd.com/watch/empyema-with-dr-shawn-st-peter-312?t=310)
- The Great Ormond Street study by Sannapa et al enrolled 60 patients and found the same results as the Kansas City trial: no difference in length of stay and a 1 in 6 failure rate, using urokinase with a 4-hour dwell time. — Shawn St. Peter summarizing a resource [Ep 1 · 18:10](https://qa.library.globalcastmd.com/watch/empyema-with-dr-shawn-st-peter-932?t=1090)
- A Spanish randomized trial of 100 patients using urokinase found no difference in length of stay and a 15% failure rate, consistent with the other two trials. — Shawn St. Peter summarizing a resource [Ep 1 · 19:40](https://qa.library.globalcastmd.com/watch/empyema-with-dr-shawn-st-peter-932?t=1180)
- The IDSA community-acquired pneumonia guidelines recommended 10 days of antibiotics after becoming afebrile, which was a grade D recommendation based on no data whatsoever. — Shawn St. Peter summarizing a resource [Ep 1 · 12:00](https://qa.library.globalcastmd.com/watch/empyema-with-dr-shawn-st-peter-932?t=720)
- A randomized trial in adults suggested more rapid clearance by adding Dornase (DNase) to fibrinolytic therapy, but it is not approved for intrapleural use in the US and requires an IND for study. — Shawn St. Peter summarizing a resource [Ep 1 · 34:50](https://qa.library.globalcastmd.com/watch/empyema-with-dr-shawn-st-peter-932?t=2090)
