Article Synopsis
- Prehospital arterial cannulation for patients with severe traumatic brain injury (TBI) is being studied to see if it delays the time to the first head CT scan compared to in-hospital cannulation.
- The retrospective study included 181 patients and found that the median time from on-scene arrival to the first head CT was similar for both groups, with only a 1-minute difference.
- The results suggest that prehospital arterial line insertion by experienced providers does not significantly delay care, supporting its use in urgent situations.*
We study the lasing dynamics of individual ZnO nanorods by time-resolved mu-photoluminescence. The distinct laser modes show gain competition and pronounced shifts as a function of excitation density. This behavior can be understood in terms of many-particle effects within an inverted electron-hole plasma and of the calculated mode spectra of the particular nanorod, whose geometry is known from electron microscope investigations.
