摘　　要：目的通过6 min步行试验评估百草枯中毒幸存者心肺代偿功能情况。方法选择56例病程1年以上的百草枯中毒幸存者为研究组,56例同龄、同性别健康人为对照组,分别进行标准6 min步行试验,比较两组个体步行距离、步行后血氧饱和度下降分数和Borg呼吸困难评分,评估百草枯中毒幸存者心肺代偿功能情况及劳动耐受情况。结果百草枯中毒幸存者与健康人的6 min步行距离分别为(604.43±101.22)m和(640.16±106.57)m,步行后血氧饱和度下降分数分别为(3.01±1.02)%、(2.79±0.97)%,步行后Borg呼吸困难评分分别为(0.70±0.66)分和(0.57±0.44)分,以上数据在两组间的差异均无统计学意义(P>0.05)。结论百草枯中毒幸存者一年后心肺代偿功能恢复良好,能够像健康人一样胜任日常活动。此类患者应重树信心,以饱满的热情重新融入社会。Objective To evaluate the cardiopulmonary compensatory function of the survivors of paraquat poisoning. Methods Totally 56 paraquat poisoning cases with the survival time over one-year were studied,while 56 healthy people matched with the age and gender were chosen as the control group. The six-minute walk test was used to assess the eardiopulmonary compensatory function and tolerance of labor. The results, including the walking distance, decreased oxygen saturation fraction, and Borg dyspnea scores were compared between the two groups. Results The walking distance of six-minute,decreased oxygen saturation fraction and Borg dyspnea scores of paraquat poisoning survivors and healthy persons were （604.43 ± 101.22） m vs. （640.16 ± 106.57） m, （3.01 ± 1.02）% vs.（2.79 ±0.97）%,and （0.70 ± 0.66） points vs.（0.57 ± 0.44） points,respectively. It showed no significant differences of these parameters between the two groups （P 〉 0.05 ）. Conclusion After good recovering of the eardiopulmonary compensatory function for one year, the survivors of paraquat poisoning cases could be competent to daily activities as healthy people. Such patients should regain confidence and integrate into the community with full enthusiasm.
