dc.description.abstractIntroduction Early detection of haemorrhagic shock can be helpful in management of trauma cases. Subclavian vein collapsibility index (SCV-CI) has been reported to be helpful in determining intravascular volume status in intensive care units. The objective of this study is to determine if SCV-CI can be used as a possible adjunct to Inferior Vena Cava Collapsibility Index (IVC-CI) in detecting early stages of haemorrhagic shock. Methods This is a prospective study which was carried out from March 2019 until March 2020. A total of 117 blood donors were recruited and ultrasonography readings of the SCV and IVC diameter before and after blood donation were recorded, along with the clinical vital signs. Results 116 patient’s data were analysed. There was significant mean difference between SCVi, SCV-CI, IVCi and IVC-CI when compared between pre and post blood donation results. There was no statistically significant difference for mean IVCe, SCVe, pulse rate, SBP, MAP and SI. There was significant positive correlation between SCV-CI and IVC-CI for the post test result, with weak strength (r<0.29). There was no significant correlation between SCV-CI and the clinical indices (i.e. PR, SBP, MAP and SI) pre and post blood donation.Conclusion Ultrasonographic measurement of SCV-CI may be a useful non-invasive tool in early detection of blood loss of at least 480cc in adult patients, however larger studies are required to validate the result
