Purpose:
Postpneumonectomy empyema (PPE) is a possible complication after a pneumonectomy in patients with lung cancer. The use of intrapleural (IP) antibiotic irrigation to treat infections in the pleural space may be indicated after systemic antimicrobial therapy, and drainage of the pleural space has been insufficient.
Methods:
Adult patients ≥18 years old who received IP antibiotic irrigation between 2006 and 2011 were included. Demographic data, past medical history, surgical procedure, systemic antibiotics, and culture data were collected. Additionally, the IP antibiotic administered, the dose, and how it was prepared and administered were collected.
Results:
A total of 18 patients were evaluated in this retrospective descriptive analysis. The majority of patients underwent an extrapleural pneumonectomy (EPP; 72%). Most patients received systemic antibiotics before IP antibiotic administration (95%). Vancomycin was the most common antibiotic used for both systemic therapy (100%) and IP irrigation (94%). The median number of IP antibiotic doses received per patient was 5.5 (interquartile range [IQR] 1-9). Recurrence of PPE within 6 months of initial PPE resolution occurred in 28% of patients. Intrapleural antibiotic irrigation was well tolerated in all patients.
Conclusion:
Vancomycin is most commonly used for IP antibiotic irrigation at our institution after patients have undergone a thoracic surgery, which was most commonly an EPP.
Insights
Intrapleural antibiotic irrigation, commonly with vancomycin, is a well-tolerated treatment for postpneumonectomy empyema (PPE) after thoracic surgery. Recurrence of PPE was observed in 28% of patients within six months.
Area of Science:
- Thoracic Surgery
- Infectious Diseases
- Pharmacology
Background:
- Postpneumonectomy empyema (PPE) is a serious complication following lung cancer surgery.
- Intrapleural (IP) antibiotic irrigation is considered when systemic therapy and drainage are insufficient.
Purpose of the Study:
- To evaluate the use and outcomes of IP antibiotic irrigation for treating PPE.
- To identify common antibiotic agents and treatment protocols.
Main Methods:
- Retrospective analysis of 18 adult patients who received IP antibiotic irrigation between 2006-2011.
- Data collected included demographics, surgical history, systemic antibiotics, and IP antibiotic details (agent, dose, preparation).
Main Results:
- Most patients (72%) underwent extrapleural pneumonectomy (EPP).
- Vancomycin was the predominant antibiotic for both systemic therapy (100%) and IP irrigation (94%).
- The median number of IP doses was 5.5, with 28% experiencing PPE recurrence within 6 months. Treatment was well tolerated.
Conclusions:
- Vancomycin is the most frequently used antibiotic for IP irrigation in PPE management at this institution.
- IP antibiotic irrigation is a safe and potentially effective adjunct therapy for refractory PPE.
