Assessment of Hypovolaemic Shock at Scene

Conclusion

Based on a large cohort of severely injured patients derived from the TraumaRegister DGU®, this study demonstrates that the PHTLS classification of hypovolaemic shock has substantial deficits in adequately risk-stratifying trauma patients. PHTLS seems to overestimate the association between tachycardia and hypotension and to underestimate mental disability in the presence of hypovolaemic shock. A critical reappraisal of the current classification may be necessary.
