Review article: Evaluating the effectiveness of arterial pressure point techniques as a first aid method for external haemorrhage control: A systematic review.

Abstract

The current ANZCOR guidelines for first aid management of life-threatening bleeding from a limb, where bleeding cannot be controlled with direct pressure, recommends the use of an arterial tourniquet. However, tourniquets required specialised training and equipment, which may not be accessible in all emergencies. This systematic review evaluated the effectiveness of arterial pressure point techniques (APPT) as a first aid measure for controlling life-threatening, non-compressible bleeding from limbs and anatomical junctions. A comprehensive literature search was conducted following the PRISMA guidelines. The search was used in five databases: PubMed, CINAHL, SportDiscuss, Proquest Central and Embase. Eligible studies included adult participants in and out of hospital settings, focusing on extremities and junctional areas. Studies assessing APPT alone or compared with other first aid techniques were included. The review included nine quasi-experimental articles, with eight having low levels of evidence. Although most reported high success rates (87.5-100%) for APPT achieving blood flow cessation, its effectiveness compared to alternative methods, such as arterial tourniquets, remains inconclusive because of methodological heterogeneity and differing success benchmarks. APPT shows promise in external haemorrhage control. Additional research with higher levels of evidence, standardised protocols and larger sample sizes is needed. Investigation in real-world scenarios is crucial to compare methods like tourniquets. Future research will determine APPT's effectiveness and its potential role as a bridging technique before tourniquet application or medical assistance.
