ObjectiveTo evaluate a calculation of pulse rate over pulse pressure as a method of predicting decompensation in patients with compensated haemorrhagic shock.MethodsA retrospective cohort study was undertaken enrolling 184 adult victims of major road trauma who were not shocked on presentation to the emergency department. A pulse rate over pressure evaluation was calculated at presentation and vital signs were observed during the first 2 h of emergency department management.ResultsThirty-one patients became shocked during their first 2 h. A ROPE value of greater than 3.0 had a positive predictive value of 53% and a value less than 3.0 had a negative predictive value of 86% for the development of decompensated shock.ConclusionsROPE is an easily applied and useful clinical tool with a ROPE of less than 3.0 being predictive of a patient remaining well and a ROPE of above 3.0 being predictive of the patient developing decompensated shock.
