Head injury remains one of the most common causes of death worldwide. Approximately 10 to
50% of patients with head injury developed disability at some points of their illness, and represent one
of the most common brain casualty encountered by neurosurgeons. Aim of the study: The study was
aimed to determine the effectiveness of semi-fowler's position on the hemodynamic function among
patients with traumatic head injury. Research design: A quasi-experimental research design was
utilized in this study. Setting: The study was conducted at Emergency Care Unit at Benha
University Hospital. Subjects: A convenient sample included 70 patients who were admitted at the
above mentioned setting. Tools: Two tools were used: patient's assessment data and hemodynamic
parameters assessment. Results: Demonstrated that less than half of the studied patients aged between
38 -highly statistically significant relations between the semi-fowler's position and the studied patient's
hemodynamic state and ABG, indifferent assessment phases, there were highly statistically significant
relations between the studied patients' age, gender, smoking habits and the APACHE score, there were
highly statistically significant relations between the studied patients in semi-fowler's position and the
Acute Physiology And Chronic Health Evaluation score in pre- position, after 15and 30 minutes of the
semi-fowler's position. Also, there were positive correlations between the studied patient's APACHE
score and their Glasgow coma scale Conclusion: There were highly statistically significant relations
between the semi-fowler's position and the studied patient's hemodynamic state and ABG results in
different assessment phases of the study. Recommendations: Replication of the study using a larger
probability sample from various geographical areas to attain more generalizable results. A study should
be carried out on the aspects of knowledge, attitude, and skill towards therapeutic positions
