Small-bore vs. large-bore chest tubes for pneumothorax: a retrospective study

Area of Science:

• Thoracic Surgery
• Pulmonary Medicine
• Medical Devices

Background:

• Pneumothorax management often involves chest tube insertion.
• The choice between small-bore and large-bore chest tubes is debated.
• Clinical evidence comparing these sizes for pneumothorax is limited.

Purpose of the Study:

• To compare the clinical efficacy and safety of small-bore (≤14 Fr) versus large-bore (>14 Fr) chest tubes.
• To evaluate outcomes such as treatment success, drainage duration, and complications.
• To assess analgesic requirements and hospital stay.

Main Methods:

• Retrospective analysis of 95 patients with pneumothorax.
• Patients grouped by initial chest tube size: small-bore (≤14 Fr) vs. large-bore (>14 Fr).
• Comparison of efficacy, drainage time, lung re-expansion, hospital stay, complications, and analgesic use. Subgroup analysis for primary and secondary spontaneous pneumothorax.

Main Results:

• Overall, no significant difference in treatment efficacy, drainage time, lung re-expansion, or hospital stay between small-bore and large-bore groups.
• Large-bore group required significantly more analgesics (P=0.049).
• In secondary spontaneous pneumothorax (SSP), small-bore tubes showed significantly shorter drainage duration and lung re-expansion time (P=0.007).

Conclusions:

• Small-bore and large-bore chest tubes have comparable efficacy for pneumothorax management.
• Large-bore tubes were associated with higher analgesic requirements.
• Small-bore tubes demonstrated potential benefits in SSP patients, with shorter drainage and re-expansion times, warranting further research.
