简要总结

The purpose of this study is to determine the efficacy and safety of Normobaric Hyperoxia combined with intravenous thrombolysis for acute ischemic stroke.

详细描述

In this study, cases of acute ischemic stroke who undergo intravenous thrombolysis within 4.5 hours from onset are included. The Normobaric Hyperoxia(NBO) group receive basic intravenous thrombolysis and given 100% oxygen inhalation at a ventilation rate of 10L/ min using a sealed non-ventilating oxygen storage mask and keep giving oxygen for 4 hours. The control group receive basic intravenous thrombolysis and given oxygen inhalation at a ventilation rate of 1L/min using nasal cannula and keep giving oxygen for 4 hours. The investigators aimed to determine the efficacy and safety of Normobaric Hyperoxia combined with intravenous thrombolysis for acute ischemic stroke.
