Manual Pressure Points Technique for Massive Hemorrhage Control-A Prospective Human Volunteer Study.

BACKGROUND: While commonly thought to be effective for management of limb and junctional hemorrhage, the manual pressure points technique was excluded from leading prehospital guidelines over a decade ago following the publication of a single human-volunteers study presenting unfavorable results. This work aimed to re-assess the efficacy and feasibility of the femoral and supraclavicular pressure points technique for temporary hemorrhage control distal to the pressure point. METHODS: A prospective, non-randomized, human volunteer, controlled environment study. In the study 35 healthy male combat medics (age 21.1 ± 1.3 years) received brief training after which they were requested to apply pressure in the femoral and supraclavicular points in attempts to stop regional blood flow, measured distally by Doppler ultrasound. Success rates in achieving flow cessation in under 2 minutes, time required for achievement of flow cessation, and cumulative flow cessation duration within a 3-minute follow-up after initial success were measured. RESULTS: For the supraclavicular point, success rates were 97.1% with a mean time to success of 12.5 (±20.9) seconds, lasting for 76.2% (±23.7) of the follow-up time. For the femoral point, success rates were 100% with a mean time to success of 5.5 (±4.3) seconds, lasting for 98.7% (±3.8) of the follow-up time. CONCLUSIONS: Manual pressure on the femoral and supraclavicular points is an applicable and efficient method for temporary hemorrhage control distal to the pressure point. As such, with additional study, this method may be considered for re-introduction to prehospital care guidelines and training programs.

Pressure Points Technique for Traumatic Proximal Axillary Artery Hemorrhage: A Case Report.

INTRODUCTION: While the pressure points technique for proximal hemorrhage control is long known, it is not recommended in standard prehospital guidelines based on a study showing the inability to maintain occlusion for over two minutes. MAIN SYMPTOM: This report details a gunshot wound to the left axillary area with complete transection of the axillary artery, leading to profuse junctional hemorrhage and profound hemorrhagic shock. THERAPEUTIC INTERVENTION: Proximal pressure of the subclavian artery was applied against the first rib (the pressure points technique) and maintained for 28 minutes. OUTCOMES: Cessation of apparent bleeding and excellent, enduring physiologic response to blood transfusion were observed. CONCLUSION: The pressure points technique can be life-saving in junctional arterial hemorrhage and should be reconsidered in prehospital guidelines.
