A comparison of the treatment outcomes of cerebral gas embolism at 2.8 ATA in comparison with 6 ATA

ABSTRACT Zhang B, Yi H, Jiang Y, Zheng C. A comparison of the treatment outcomes of cerebral gas embolism at 2.8 ATA in comparison with 6 ATA. Undersea Hyperb Med. 2024 Fourth Quarter; 51(4):341-346. Objective: To investigate the effect of 6 ATA air/ oxygen treatment scheme and 2.8 ATA oxygen inhalation scheme on cerebral gas embolism. Methods: 29 patients with cerebral gas embolism admitted from January 2014 to June 2022 were retrospectively included. The patients were divided into 6 ATA air/ oxygen treatment scheme group (14 cases) and 2.8 ATA oxygen inhalation therapy scheme group (15 cases). Glasgow Coma Scale (GCS) was used to evaluate the therapeutic effect before and after treatment. The effective standard of treatment: recovery of consciousness (GCS scores>8). Results: There was no significant difference between two groups in terms of gender, age, cause of disease, time of onset and GCS score before treatment (P>0.05). There was not significant difference between two groups in terms of GCS score after 1 day and 1 week of treatment (P>0.05). After 1 week of treatment, 78.6% (11/14) of patients in the 6 ATA group and 80.0% (12/15) in the 2.8 ATA group improved. Conclusion: The 2.8 ATA oxygen inhalation scheme can effectively treat cerebral gas embolism, and effect is similar to the 6 ATA air/ oxygen treatment scheme.
