目的观察BiPAP呼吸机正压给氧对放射治疗(简称放疗)的影响,以探索提高中晚期肺癌治疗的新途径。方法确诊的肺癌患者30例随机分为联合治疗组和单纯放疗对照组,前者采用BiPAP呼吸机经鼻面罩正压通气给氧联合常规放疗,后者采用常规放疗(6MV-X)。观察通气前、后血氧分压(PaO2)、血氧饱和度(SaO2)变化和放疗前、后胸部X线片、血常规、细胞免疫功能变化,以及毒副反应发生情况。结果①BiPAP呼吸机经鼻面罩正压通气给氧可明显提高 PaO2,最高可增加7.5 kPa,同时SaO2均维持在95%以上。肺癌治疗有效率较对照组增加6.7个百分点。②治疗组放疗前后细胞免疫功能无明显变化(P>0.05),而对照组在放疗后淋巴细胞转化率、CD4及CD4/CD8比值明显降低(P<0.01)。③治疗组仅1例出现白细胞减少( 6.7%),而对照组有5例出现白细胞明显降低(33.3%),需用升白药物才能继续完成放疗。胃肠道反应发生较对照组明显减少。结论 BiPAP呼吸机经鼻面罩正压通气给氧辅助肺癌放疗有一定疗效,可明显提高机体氧分压,对骨髓及细胞免疫功能有一定保护作用,亦能减少放疗所引起的毒副作用。
目的觀察BiPAP呼吸機正壓給氧對放射治療(簡稱放療)的影響,以探索提高中晚期肺癌治療的新途徑。方法確診的肺癌患者30例隨機分為聯閤治療組和單純放療對照組,前者採用BiPAP呼吸機經鼻麵罩正壓通氣給氧聯閤常規放療,後者採用常規放療(6MV-X)。觀察通氣前、後血氧分壓(PaO2)、血氧飽和度(SaO2)變化和放療前、後胸部X線片、血常規、細胞免疫功能變化,以及毒副反應髮生情況。結果①BiPAP呼吸機經鼻麵罩正壓通氣給氧可明顯提高 PaO2,最高可增加7.5 kPa,同時SaO2均維持在95%以上。肺癌治療有效率較對照組增加6.7箇百分點。②治療組放療前後細胞免疫功能無明顯變化(P>0.05),而對照組在放療後淋巴細胞轉化率、CD4及CD4/CD8比值明顯降低(P<0.01)。③治療組僅1例齣現白細胞減少( 6.7%),而對照組有5例齣現白細胞明顯降低(33.3%),需用升白藥物纔能繼續完成放療。胃腸道反應髮生較對照組明顯減少。結論 BiPAP呼吸機經鼻麵罩正壓通氣給氧輔助肺癌放療有一定療效,可明顯提高機體氧分壓,對骨髓及細胞免疫功能有一定保護作用,亦能減少放療所引起的毒副作用。

Objective To investigate the effect of positive pressure ventilation on radiosensitivity of the patients suffering from primary lung cancer. Methods Thirty cases of lung cancer were randomly divided into two groups: ① combining therapy group: patients treated with posi tive pressure ventilation using BiPAP respirator and radiotherapy;② simple radi otherapy group. The changes of PaO2, SaO2, blood white cells and the cellula r immunological function were observed before and after treatment. Resul ts Nasal or naso-facial positive pressure ventilation with BiPAP respi rator increased PaO2 significantly with the maximum of 7.5 kPa, SaO2 was ma inteined at above 95%. No significant change for the cellular immunological func tion was found in the combining therapy group (P>0.05)and only one patient with leukopenia(6.7%). But in the radiotherapy group, the lymphocyte transfor mation efficiency and the ratio of CD4/CD8 were obviously decreased(P<0 .01), and leukopenia was found in 5 cases(33.3%). Conclusion Nasal or naso-facial positive pressure ventilation with BiPAP respirator could improve the effect of radiotherapy for lung cancers. It could also increase PaO 2 significantly and has protective rote to the marrow and cellular immunologic al function of the patients.
