Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This prospective observational study aims to investigate the frequency and clinical significance of biofilm formation on thoracic chest drains used after thoracic surgery. Biofilms are structured bacterial communities that adhere to surfaces and can promote infection and antibiotic resistance. In this study, small samples from the tips of chest drains will be collected under sterile conditions at the time of drain removal and analyzed in the microbiology laboratory.

The main objectives are to evaluate the relationship between the duration of chest drain placement and the presence of biofilm, and to identify the antibiotic resistance profiles of microorganisms isolated from these biofilms. Secondary outcomes include the association between biofilm formation, postoperative infections (such as empyema or wound infection), and the length of hospital stay.

This study will be conducted at Ondokuz Mayıs University Faculty of Medicine, Department of Thoracic Surgery, in collaboration with the Department of Microbiology. The findings are expected to contribute to better understanding of optimal drain management and infection prevention strategies after thoracic surgery.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Group 1 -Short Drain Duration (≤2 Days)

Participants whose thoracic chest drains were removed within 2 days after surgery. Drain tip samples from these patients will be analyzed for biofilm formation and microbiological culture.

Chest Drain Tip Sampling

Intervention Type OTHER

No active intervention; routine chest drain removal followed by microbiological and biofilm analysis of drain tip samples.

Group 2 - Moderate Drain Duration (3-4 Days)

Participants whose thoracic chest drains remained in place for 3 to 4 days postoperatively. Drain tips will be examined for biofilm presence and bacterial growth patterns.

Chest Drain Tip Sampling

Intervention Type OTHER

No active intervention; routine chest drain removal followed by microbiological and biofilm analysis of drain tip samples.

Group 3 - Long Drain Duration (≥5 Days)

Participants with chest drains in place for 5 days or longer. Biofilm formation, bacterial species identification, and antibiotic resistance profiles will be evaluated.

Chest Drain Tip Sampling

Intervention Type OTHER

No active intervention; routine chest drain removal followed by microbiological and biofilm analysis of drain tip samples.
