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.
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.
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.
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.
虽然普遍认为手动压迫点技术对于四肢和关节出血的管理是有效的,但在十多年前,一项单个人体志愿者研究结果不佳,导致该技术被排除在主要的院前指南之外。这项工作旨在重新评估股动脉和锁骨上压迫点技术在压迫点以下临时控制出血的效果和可行性。
这是一项前瞻性、非随机、人体志愿者、对照环境研究。在这项研究中,35 名健康的男性战斗医务人员(年龄 21.1±1.3 岁)接受了简短的培训,然后要求他们在股动脉和锁骨上按压,以试图阻止多普勒超声测量的局部血流。测量在 2 分钟内达到血流停止的成功率、达到血流停止所需的时间以及初始成功后 3 分钟内的累计血流停止时间。
对于锁骨上压迫点,成功率为 97.1%,平均成功时间为 12.5(±20.9)秒,持续时间为 76.2%(±23.7)。对于股动脉压迫点,成功率为 100%,平均成功时间为 5.5(±4.3)秒,持续时间为 98.7%(±3.8)。
手动压迫股动脉和锁骨上压迫点是一种适用于压迫点以下临时控制出血的有效方法。因此,在进一步研究后,这种方法可能会被考虑重新引入到院前急救指南和培训计划中。
