Highlights ■ This randomized controlled trial in elective neurosurgery adds important evidence to the growing body of literature comparing Plasma-Lyte 148 with 0.9% saline in specialized surgical populations. ■ Plasma-Lyte 148 demonstrated superior acid-base homeostasis with significantly higher bicarbonate levels and base excess at surgical completion, whereas 0.9% saline induced hyperchloremia in the saline group. ■ The biochemical advantages of Plasma-Lyte 148 align with current evidence supporting balanced crystalloids as the preferred choice in perioperative fluid management. ■ These findings […]

ABSTRACT Objective: To ascertain the safety, effectiveness and reproducibility of screening potential neurosurgical patients by means of smartphones. Methods: This is a retrospective and multicentric study. Data were collected from the medical records of patients subjected to real emergency neurosurgical evaluations and compared with assessments by neurosurgeons using smartphones to determine the feasibility of identifying changes in cranial computed tomography scans, potentially serious conditions of patients, and the need for transfer to reference centers. Results: We analyzed 232 cases. The […]

OBJECTIVE: To evaluate tools for the fusion of images generated by tomography and structural and functional magnetic resonance imaging. METHODS: Magnetic resonance and functional magnetic resonance imaging were performed while a volunteer who had previously undergone cranial tomography performed motor and somatosensory tasks in a 3-Tesla scanner. Image data were analyzed with different programs, and the results were compared. RESULTS: We constructed a flow chart of computational processes that allowed measurement of the spatial congruence between the methods. There was […]
