Abstract:
Objective To observe the effect of hyperbaric oxygen (HBO) therapy on neurological functioning in rats modelling cerebral hemorrhage (ICH).Methods Sixty Sprague-Dawley rats had intracerebral hemorrhage induced by injecting autologous blood.They were then randomly divided into an HBO-free group and an HBO group,each of 30 according to a random number table.The HBO group was further divided into HBO 3 h,HBO 6 h,HBO 1 d,HBO 2 d and HBO 7 d groups which received HBO therapy for 3 hours,6 hours,1 day,2 days and 7 days respectively.Each had 6 members.The HBO-free rats were also divided into analogous HBO-free 3 h,HBO-free 6 h,HBO-free 1 d,HBO-free 2 d and HBO-free 7 d groups,and give no HBO intervention.All of the rats were evaluated for neurological impairment using the Longa scoring method before the treatment and 10 days,20 days and 30 days afterward.Results After 10,20 and 30 days of HBO treatment,there were significant differences in neurological functioning between each pair of HBO-free and HBO-treated groups.After 10 and 20 days of HBO treatment the average neurological function score of the HBO 3 h group was significantly different from that of the HBO 2 d group.The average score in the HBO 7 d group was also significantly different from that of the HBO 3 h,HBO 6 h,HBO 1 d and HBO 2 d groups after 10,20 and 30 days of HBO treatment.The average scores of the HBO 3 h,HBO 6 h,HBO 1 d and HBO 2 d groups improved significantly between 10 and 20 days after the treatment.The average score of the rats which received 30 days of treatment was also significantly different from those after 10 and 20 days.Conclusion HBO treatment can improve neurological function after cerebral hemorrhage,at least in rats.The best time to start HBO treatment is no later than 24 hours after the hemorrhage.The curative effect increases with extension of the treatment's duration.
