Hemodynamic Monitoring of Brain-Injured Patients at the Lubumbashi University Clinics: Preliminary Study on the Impact of Transcranial Doppler (TCD) versus S100 Beta Protein Assay in Therapeutic Optimization in a Resource-Limited Environment

Introduction: Overcrowding in emergency departments is one of the main public health problems encountered in this sector over the last decade. Aim: This work aims to assess the current state and challenges of neurosurgery in resource-limited settings. Methodology: We conducted a prospective interventional study from November 2024 to February 2025, in total 3 months, carried out at the University Clinic of Lubumbashi in the Surgery, Emergency and Intensive care services. A total of 28 patients were included. Results: The average age of our patients was 34.86 years, with male predominance, with a male-to-female ratio of 2.3. Altered consciousness was the most common presenting symptom. The average time to consult our patients was 359.1 hours, and the average Glasgow score was 11. The brain CT scan was performed in 81.48% of cases. The average time to perform TCD was 17.23 hours, an IP greater than 1.20 (92.59% of cases). The average time to S100 beta protein dosage was 15.24 hours and a surgical completion rate of 11.11% of cases. Conclusion: TCD and S100 β protein assay are two complementary tools in the evaluation of patients with traumatic brain injury.
