Abstract
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.
