Heart Rate Variability in Trauma Patients
In Brief
An observational study for Trauma. Completed, enrolled 95 participants across 1 site.
Detailed Summary
The purpose of this study is to develop new triage tool for trauma patients based on HRV. EKG will be prospectively measured in trauma patients in two locations: in the prehospital setting (the field and during transport by helicopter) and in the hospital setting. In each case HRV will be derived from the EKG signal, will be correlated with other non-invasive signals (e.g. near infrared spectroscopy (NIR), and bispectral EEG (BIS)), along with other routinely measured variables (blood pressure, respiratory rate, pulse oximetry, etc), will be correlated with injury severity and day of discharge. An algorithm will be constructed using multiple linear regression. The hypotheses are: 1. reduced HRV in the field correlates with bad outcome; 2. the specificity and efficiency of HRV as a screening tool can be improved by controlling factors such as heart rate, age, gender, respiratory rate, and pulse oxygen saturation; 3. an easy to interpret HRV index can be derived that can be used for trauma triage or diagnosis.
