Needle Cricothyroidotomy by Intensive Care Paramedics.

Cricothyroidotomy is an advanced airway procedure for critically ill or injured patients. In Victoria, Australia, intensive care paramedics (ICPs) perform needle cricothyroidotomy utilizing the proprietary QuickTrach II (QTII) device. Recently, an Ambulance Victoria (AV) institutional change in workflow included pre-puncture surgical incision to assist in successful placement. This review aims to explore whether a surgical pre-incision prior to the insertion of the device improved overall procedural success rates of needle cricothyroidotomy using the QTII. This was a retrospective review of all patients who received a needle cricothyroidotomy by ICPs from May 1, 2015 through September 15, 2020. Data and patient care records were sourced from the AV data warehouse. A total of 27 patients underwent a needle cricothyroidotomy with the mean age of patients being 50.2 years. Most cricothyroidotomies were performed using the QuickTrach II kit (92.6%). Prior to modification of the QTII procedure, front-of-neck access (FONA) success was 50.0%; however, this improved to 82.4% after the procedures recent update. The overall success rate of all paramedic-performed needle cricothyroidotomy during the study period was 74.1% (n = 20). This review demonstrates that propriety devices such as the QTII device achieve a low success rate for a FONA intervention. Despite the low frequency of this procedure, ICPs with extensive training and regular maintenance can perform needle cricothyroidotomy using scalpel assistance with a reasonable success rate. But when compared to the broader literature, success rate using a more straightforward technique such as a surgical cricothyroidotomy technique is likely going to be higher.
