摘要
为了提高对持续性植物状态（ＰＶＳ）的疗效，我们自１９９１年来用高压氧（ＨＢＯ）治疗ＰＶＳ１６例，取得了总有效率为８７％的显著疗效。疗效与患者的年龄、治疗次数及治疗时的病期有关，即年轻者疗效较高，ＨＢＯ治疗在７０次以上者疗效显著，病期越短疗效越好。文中对ＨＢＯ治疗ＰＶＳ的机理进行了探讨。
n order to enhance the therapeutic
effect on persistent vegetative state(PVS),16 patients weretreated with hyperbaric
oxygen(HBO).The patients were 12 males and 4 females aged 10～64(mean36.5 yrs) and were
admitted in our hospital between the years 1991～1994.The main causes includedhead
trauma(9 cases), poisoning(4 cases),heart arrest(2 cases)and encephalitis(1 case).Walshe’
scriteria and Rappaport’s disability categories were used for the diagnosis of PVS.The
patients were ex-posed to HBO(100% O2 at 250～300 kPa) for 30 min×2 with an interval of 10
min,1～2/d and 10 da course,and the whole treatment was between 30～130 times. The results
showed a total effective rateof about 87%. The efficacy was correlated with the age of the
patients, 66.7% of those almost recov-ered were under 30.It was also correlated with the times
of HBO applied and the duration of PVS.Pa-tients treated with HBO more than 70 times had
more significant clinical effect, and that the youngerthe patient and the shorter the disease
duration the better the result.It was concluded that HBO is aneffective method in the treatment
of PVS.
