Quick Overview

The MedSource 14g Decompression Needle is a single-use, sterile needle thoracostomy system used by ALS providers, tactical medics, and certified paramedics to perform emergency pleural decompression in casualties presenting with life-threatening tension pneumothorax.

The device consists of a 14-gauge triple-facet stainless steel needle paired with a 3.25-inch rigid PTFE catheter, housed in a rugged hard shell case with a textured twist-to-open cap designed for one-handed access under field conditions. The 3.25-inch catheter length is specifically selected to reliably reach the pleural space in the majority of adult casualties, and the rigid PTFE material resists kinking after needle withdrawal to maintain a patent decompression channel. Deployment begins with confirmation of tension pneumothorax indicators including progressive respiratory distress, absent unilateral breath sounds, jugular vein distention, and hemodynamic instability unresponsive to other interventions.

Insertion is performed at the 2nd intercostal space on the mid-clavicular line as the primary site, or the 4th to 5th intercostal space on the anterior axillary line as the TCCC alternate. The needle is advanced perpendicular to the chest wall over the superior border of the rib to avoid the neurovascular bundle. Successful placement is confirmed by an immediate, audible rush of escaping air from the pleural space.

Post-intervention protocol requires securing the catheter hub without occluding the opening, continuous reassessment of respiratory status and vital signs, and documentation of the procedure, time, site, and casualty response for continuity of care and handoff. The entire assembly is single-use and must be treated as a biohazard following deployment.

Field Application Steps

1. CONFIRM INDICATIONS: Verify the casualty presents with signs of tension pneumothorax including severe respiratory distress with confirmed or suspected chest trauma, unilateral decreased or absent breath sounds, and hemodynamic compromise. Rule out contraindications before proceeding.

2. ASSEMBLE EQUIPMENT AND POSITION CASUALTY: Ensure you have the MedSource Decompression Needle, antiseptic wipes, and appropriate PPE including gloves. Place the casualty in a supine or semi-recumbent position if tolerated and fully expose the chest.

3. IDENTIFY INSERTION SITE: For the primary site, palpate the clavicle, track to the 1st rib, 1st intercostal space, 2nd rib, and 2nd intercostal space on the mid-clavicular line of the affected side. If using the TCCC alternate site, locate the 4th or 5th intercostal space on the anterior axillary line, generally level with the nipple line in males.

4. PREPARE THE SITE: Cleanse the identified insertion point with an antiseptic wipe using a circular motion from inside to out. Allow the site to air dry before proceeding.

5. DEPLOY THE DEVICE: Remove the needle and catheter assembly from the hard shell case by firmly twisting the textured cap to break the factory seal. Maintain control of the sterile assembly throughout.

6. EXECUTE INSERTION: Grasp the catheter hub and position the needle perpendicular at 90 degrees to the chest wall, directly over the superior border of the rib below the target intercostal space. This position avoids the neurovascular bundle running along the inferior rib border.

7. ADVANCE THE NEEDLE: Apply firm, steady pressure to drive the needle through the skin, fascia, intercostal muscle, and parietal pleura. A distinct tactile pop may be felt as the needle enters the pleural space.

8. CONFIRM PLACEMENT: Halt advancement immediately upon entry into the pleural space. The definitive confirmation of correct placement is an immediate and audible rush or hiss of escaping air. Absence of this sign indicates misplacement or misdiagnosis.

9. ADVANCE CATHETER AND WITHDRAW NEEDLE: Hold the needle hub completely stationary and use the other hand to advance the PTFE catheter fully over the needle until the catheter hub is flush with the casualty's skin. Withdraw the needle completely, leaving only the catheter in the pleural space.

10. DISPOSE OF THE NEEDLE: Immediately place the exposed needle into a designated sharps container or render it safe per available protocols. Do not set the needle down or allow it to become a secondary hazard.

11. SECURE THE CATHETER: Fix the catheter hub to the chest wall using a commercial securing device or tape. Do not fully occlude the catheter opening, as the channel must remain patent for continued air evacuation.

12. REASSESS AND DOCUMENT: Continuously monitor the casualty's respiratory status, breath sounds, and vital signs for improvement. Record the procedure, time of intervention, insertion site, and the casualty's response for handoff and continuity of care.
