OBJECTIVE: To observe the effect of acupuncture plus hyperbaric oxygen (HBO) on cerebral blood perfusion in patients with delayed encephalopathy after carbon monoxide poisoning (DEACMP).
METHODS: Twenty-eight patients with DEACMP were randomly divided into acupuncture group (n=14 cases) and control group (n=14 cases). Patients of the acupuncture group were treated by using “Xingnao Kaiqiao” needling technique (specific set of acupuncture points as Yintang ［EX-HN3］, Shangxing ［GV23］, Baihui ［GV20］, Sishenchong ［EX-HN1］, Fengchi ［GB20］, Taichong ［LR3］, etc., and strong stimulation) combined with HBO in an air pressurized tank, and those of the control group treated by simple HBO. The treatment was conducted once a day, 5 days a week for 6 weeks. All the patients underwent head routine magnetic resonance imaging (MRI) and intravoxel incoherent motion imaging(IVIM) scan before and after the treatment. The values of pseudo-diffusion coefficient D (D*) and perfusion fraction (f) of the bilateral semi-oval centers were measured by using MITK software package to calculate the ave-rage fD* value (f×D*). The Barthel index (BI) score was used to assess the patients’ daily living ability, and the correlation between parameter values was evaluated by Pearson method.
RESULTS: After the treatment, the values of f, fD* and BI scores were significantly increased in both acupuncture group and control groups (P<0.05). The values of the 3 indexes were significantly higher in the acupuncture group than those in the control group (P<0.05). The values of f and fD* were positively correlated with BI score (P<0.05), with the correlation coefficients being 0.822, 0.636 and 0.601, respectively between the fD* and f, BI and f, and BI and fD*.
CONCLUSION: Acupuncture combined with HBO can significantly improve the low-perfusion of bilate-ral semi-oval center and daily living ability in patients with DEACMP, being significantly superior to simple HBO therapy in the curative effect.
