Study on Time to Hyperbaric Oxygen Treating Acute Cerebral Infarction

Objective: To explore the relationship between initial time to hyperbaric oxygen (HBO) therapy and therapeutic efficacy in patients with acute cerebral infarction. Methods: 315 cases of acute cerebral infarction were divided into 3 groups according to admitted sequence: early group which included 105 cases treated by HBO from several h to 3 days after onset of acute cerebral infarction; median group which included 106 cases (5-7 days); late group which included 104 cases (10 days). All of patients were subjected to general therapy. Their therapeutic efficacy were evaluated according to the grade standard of nerve function default following shock after the patients received 20 times of HBO therapy. Results: Total effective rate or total markedly effective rate in early group was significantly higher than that in median or late group (P0.05), but there was no significant difference between median group and late group in total effective rate and total markedly effective rate (P0.05). Conclusion: The patients with acute cerebral infarction should be given HBO therapy as possible as early.
