Heart Rate Variability in Trauma Patients (HRV)
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:
- reduced HRV in the field correlates with bad outcome;
- 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;
- an easy to interpret HRV index can be derived that can be used for trauma triage or diagnosis.

Åtgärdsbeskrivning |
Tidsram |
---|---|---|
Base Deficit </= -6
Tidsram: Upon arrival to the hospital
|
Indicator for volume deficit and resuscitation.
Number of participants with Base Deficit </= -6 is reported.
Base deficit is the absolute difference of the base deficit from its normal range (-2 to 2), and is used as an indicator for traumatic injuries.
A base deficit </= - 6 signifies volume deficit and the need for volume resuscitation with fluids, blood or blood products either alone or in combination.
|
Upon arrival to the hospital
|
Serious Injury
Tidsram: Upon arrival to the hospital
|
A patient was classified as seriously injured when two of three blinded trauma surgeons classified the patient as similar after review of each patient chart and final diagnoses in retrospect.
|
Upon arrival to the hospital
|
Life Saving Intervention in the Operating Room.
Tidsram: Upon arrival to the hospital
|
A patient was classified as having a life saving intervention in the operating room when two of three blinded trauma surgeons classified the patient as similar after review of each patient chart and final diagnoses in retrospect.
|
Upon arrival to the hospital
|
SDNN: Standard Deviation of the Normal-to-normal R-R Interval
Tidsram: Upon arrival to the hospital
|
A determination of HRV derived from the time domain of a standard electrocardiogram, primarily determined by measuring the randomness of the exact occurrence of when one R wave follows a preceding R wave.
