Abstract

PURPOSE: There have been many reports that point to the increasing death and emergency operation rate in traumatic hemorrhagic shock patients. The purpose of this study was to discover the clinical difference between the hypotensive traumatic patients and the non-hypotensive traumatic patients that had been managed in intensive care unit (ICU).
METHODS
We retrospectively reviewed the medical records of 122 patients admitted to ICU for trauma from January 2001 to December 2002. We compared the hypotensive (systolic blood pressure (SBP) < 90 mmHg) group with the non-hypotensive group about age, diastolic blood pressure, initial hemoglobin, Injury Severity Score (ISS), Glasgow Coma Scale (GCS), Revised Trauma Score (RTS), transfusion volume at emergency department, blood pH, blood base deficit, duration of admission, ICU stay, death rate, transfusion volume and others.
RESULTS
There was no difference between two groups in age, causes of injury, situation whether or not the patient was directly transported from the scene and ISS. But there were differences between two groups in initial hemoglobins, GCS, RTS, blood pH, blood base deficit, duration of admission, ICU stay, and death rate. It was documented that the ICU stay correlated with systolic blood pressure, diastolic blood pressure, initial hemoglobin, blood base deficit, ISS, GCS, and RTS but not correlated with transfusion volume in emergency department.
CONCLUSION
Systolic blood pressure is not the sensitive parameter of blood loss. Various kinds of indices of hypotensive group are more severe than non-hypotensive group. If traumatic patients are hypotensive blood pressure on arrival at emergency department, we should be careful of the state of these patients.
