Quantifying the impact of prehospital arterial line insertion on scene time

The authors aimed to investigate the impact of prehospital arterial line insertion on scene time and its potential implications for patient transport to definitive care. Their systematic review of four studies found a consistent association between arterial line insertion and increased scene time, ranging from 4 to 34.4 minutes, but noted that the clinical significance of this delay remains unclear and may vary depending on the context.
