Where is a chest tube typically placed?

• A. 5th or 6th Mid Axillary line
• B. 2nd Intercostal Mid Clavicular
• C. 8th Intercostal Posterior
• D. 3rd Intercostal Near Sternum

Answer: (A)

Chest tubes are placed on the lateral chest wall to access the pleural space and drain air or blood. The standard site is the mid-axillary line at about the fifth intercostal space. This location provides easy, direct access to the pleural cavity, a favorable angle for the tube, and a safer distance from the heart and major vessels. Importantly, you insert just above the rib to avoid injuring the intercostal vessels and nerves that run along the inferior border of each rib. Other sites described aren’t typical: the second intercostal space at the midclavicular line is used for needle decompression of a tension pneumothorax, not for a chest tube. The 8th intercostal space posteriorly or the 3rd intercostal space near the sternum pose higher risk to internal organs and are technically less appropriate for standard drainage.
