Abstract
Trauma is mechanical damage to the body caused by an
external force. Chest trauma is one of the most common causes of
mortality in the fourth decade of life
Trauma scoring systems are routinely used to evaluate and
monitor traumatic injury outcomes. It is done in order to reduce the
number of preventable deaths. Trauma and injury severity score
(TRISS) is a combination index based on Revised Trauma Score
(RTS), Injury Severity Score (ISS), and patient’s age. The TTSS
developed by Pape et al to predict mortality in thoracic trauma
patients. It combines the patient‘s age, resuscitation parameters, and
radiological assessment of the thorax.
The aim of this study is to identify the validity of the TRISS
and TTSS as predictors of in-hospital outcome in Patients with
thoracic trauma.
This study included 100 patients presented to Emergency
Department of Menoufia University Hospitals in a trauma event.
All patients were subjected to full history taking, assessed and
managed through (ATLS) protocol including:
1. Primary survey.
2. Secondary survey.
3. Investigations.
Evaluation using both TRISS &TTSS scores were carried out at
the same setting with no time interval during the first 24 hours after
resuscitation and ICU admission.
Summary
78
The results of this study within the limitations of this study shown
that:
- The majority of our patients were males 76 (76%) with and mean
age (39.5±19.9).
- The most common cause of injury was road traffic accident (RTA)
(50%).
- Most of studied patients (87%) of patients had been survived.
- The best cut off value of TRISS score for prediction of mortality
among studied patients is 24.55% with sensitivity (the ability to
predicting mortality) of 92.3% and specificity (the ability to
exclude mortality) of 81.6%.
- The best cut off value of TTSS score for prediction of mortality
among studied patients is 4.5% with sensitivity (the ability to
predicting mortality) of 84.6% and specificity (the ability to
exclude mortality) of 80.5%.
The results of our study, give us the support to use both TRISS
and TTSS scores for mortality prediction in critically ill trauma
patients.
