Trial Outcomes & Findings for Heart Rate Variability in Trauma Patients (NCT NCT00795535)

NCT ID: NCT00795535

Last Updated: 2015-02-09

Results Overview

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.

PRIMARY outcome

Timeframe: Upon arrival to the hospital

Population: 75 patients with complete HRV and trauma registry data

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.

PRIMARY outcome

Timeframe: Upon arrival to the hospital

Population: 75 patients with complete HRV and trauma registry data

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.

PRIMARY outcome

Timeframe: 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.
