Needle Pleural Decompression
Indications
- tension pneumothorax
Procedure
Anatomic Location
- classically the 2nd intercostal space at the mid clavicular line (ICS2-MCL) is taught as the ideal location for a needle decompression
- new evidence (SRMA) Link to discussion suggests that the 4th -5th ICS at the anterior axillary line (ICS-AAL) has the lowest predicted failure rate of needle decompression with a 5cm angiocatheter.
- New ATLS guidelines (2018+) recommends the 4-5 ICS-mid-axillary line for decompression in adult patients.
Needle
Length
- ATLS recommends a 5 cm (2 inch) angiocatheter. This is safe, does not cause injuries to underlying structures when aimed perpendicularly to the chest wall at the ICS2-MCL and the ICS4-AAL
- Longer catheters (e.g. 8 cm) cause increased risk of injury (9-30%) to underlying structures.
- Shallow angle of entry increases risk of injury.
- consider 3.25 to 4" catheters
Catheter Gauge
- 14G is standard. Larger is better.
Steps
- Locate the site (2 ICS-MCL or 4-5 ICS-MAL).
- Sterilize if possible.
- Attach needle/catheter to syringe. (OPTIONAL)
- Over an over-the needle catheter (angiocath) at the site, over the rib. Apply negative pressure (IF USING SYRINGE)
- Once rush of air is detected, advance the catheter and withdraw the needle.
- Proceed to insert a chest tube) in the 5th ICS at the AAL (for definite management).
