Randomized Controlled TrialThe effect of furosemide on intravascular volume status and electrolytes in patients receiving mannitol: an intraoperative safety analysis.
Mannitol is often used during intracranial surgery to improve surgical exposure. Furosemide is often added to mannitol to augment this effect. The concern exists, however, that the augmented diuresis caused by the addition of furosemide to mannitol may cause hypovolemia and hypoperfusion, hypokalemia, and hyponatremia. We examined the intraoperative safety of low-dose furosemide (0.3 mg/kg) combined with mannitol (1 g/kg). ⋯ Despite an increase in urine output by as much as 67%, adding low-dose furosemide to mannitol does not seem to produce significant electrolyte derangements or hypovolemia compared with the administration of mannitol alone.

Image-guided transcranial Doppler sonography for monitoring of defined segments of intracranial arteries.
Transcranial Doppler sonography (TCD) is widely used in neurointensive care. Image guidance (IG) could simplify secure vessel identification and reduce interinvestigator and intrainvestigator variability. The present study was purposed to investigate the precision and reproducibility of image-guided TCD. ⋯ Data suggest that image-guided TCD allows for accurate examinations with high intraprocedural and high interprocedural reproducibility. It facilitates identification of specific vessel segments and generation of standardized examination protocols for serial examinations.
