Comparison between BIS and clinical cales of prognosis in intubated patients with different pathologic head injuries due to acute head trauma admitted to the ICU in The Rasool Akram Hospital

There is still insufficient evidence to warrant the routine use of Bispectral Index (BIS) in the intensive care unit. One way of evaluating the usefulness of BIS in monitoring the level of consciousness in ICU patients is demonstration its degree of correlation to commonly used scales of prognosis. The aim of this study is to Compare BIS with APACHE II and SOFA Score in Intubated Patients with Different Pathologic Injuries of the Brain Due to Acute Head Trauma Admitted to the ICU.
30 intubated head trauma patients over 15 years old admitted to the ICU were included in this cross-sectional study. In the first three days of admission, each patient underwent monitoring of BIS every sixty minutes just for six hours a day. All the hypnotic drugs were discontinued six hours before starting of monitoring and only opioids (fentanyl) were administered if needed. APACHE II in the first day of admission, SOFA Score in the first three days, type of cranial injury, and laboratory data were all collected. Statistical analyses were used to evaluate the data. P APACHE II and SOFA Score, had no statistically significat correlations with mean BIS in each three days of study and the mean BIS total. Mean BIS in the second and third days had statistically significant differences in different types of cranial lesions (contusion, subdural hemorrhage, subarachnoid hemorrhage).
In acute head trauma patients BIS has not acceptable conformity with APACHE II and SOFA Score. Different kinds of acute traumatic cranial lesions with different prognosis may have different values in BIS monitoring.
