About

The aim of this study is to evaluate the efficacy on healthy subjects of Point of Care ultrasonographically guided external aortic compression compared to the manual technique already described.

Full description

Manual Proximal External Aortic Compression (M-PEAC) has been described for temporizing non-compressible hemorrhage. Point of Care Ultrasonographically guided External Aortic Compression (POCUS-PEAC), a new technique, has been used for management of junctional hemorrhage. The aim of this study is to compare the efficacy of US-PEAC to M-PEAC in reducing the distal arterial flow. This study also evaluates whether a small weight operator would benefit most of the US-PEAC compared to a standard weight operator. Other objectives are to evaluate pain and secondary effects. We will conduct an experimental crossover trial on healthy volunteers. Subjects will be recruited using a convenient sample. M-EAC and US-EAC will be performed on each subject. Femoral arterial flows will be measured by Doppler before and after each compression. Femoral flow reduction will be calculated for each technique and compared. The compression will be first accomplished by an 80 kg operator followed by a 57 kg operator. After each compression, pain will be evaluated using a visual analog scale (VAS). Fifteen minutes after the intervention, pain will be recorded using the same VAS. A follow-up will be ensured at 24 hours and at one week to evaluate for secondary effects.
