Intrapleural Antimicrobial Irrigation for Postpneumonectomy Empyema in Patients With Lung Cancer

Abstract

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.
