Is air transport of stroke patients faster than ground

2020-8-18Background Helicopters are widely used for interhospital transfers of stroke patients but the benefit is sparsely documented We hypothesised that helicopter transport would reduce system delay to thrombolytic treatment at the regional stroke centre Methods In this prospective controlled observational study we included patients referred to a stroke centre if their ground transport time
