The Relationship Between The Coma Scores(GCS, RTS) and ICP In Patients With Serious Head Trauma

Abstract

INTRODUCTION: Glasgow coma scale (GCS) and weighted revised Mart20 04.4: 1. TORKi YE AciL Tıp DERGI sI trauma (RTSw) scores are commonly used for detecting the early neurological status and short time mortality of trauma patients. PURPOSE: The purpose of our study is to determine the correlation between GCS. RTSw and cerebral perfusion pressure (CPP). opening intracranial pressure (lCP) in major head trauma patients in the emergency department.
METHODS: Our study is a prospective. observational clinical study Patients whose GCS < 9 and to whom we inserted external ventricular drainage to follow their intracranial pressure were included to the study. A study form including patients' characteristics. initial GCS and RTSw scores was recorded for each patient. During the procedure. opening LCP was recorded and then CPP was calculated. Patient charts were used during the follow-up period.
RESULTS: Twenty-three of 81 major head trauma patients were eligible for inclusion. The median of GCS score was 6. The means and standard deviation of the opening lCP. CPP. RTSw were 25.6: t 3.7 cmH20, 74.6: t 20.5 mmHg. 111.863: t 16.813 respectively. We found a weak negatiye linear correlation (p = 0.007. r = -0.546) between the initial GCS score and opening ICP. Furthermore. RTSw and CPP had a powerful correlation (p = 0.000. r = 0.850).
CONCLUSlON: Emergency physicians may use GCS score and RTSw as indirect predictors of LCP and CPP. respectively in their clinical practice.
