有害气体中毒应用高压氧疗时效的分析及护理

The Analysis on the Effect of Hyperbaric Oxygen Treatment in Deleterious Gas Poisoning

目的探讨高压氧（HBO）在治疗二氧化硫、烟雾（混合气体）、一氧化碳等急性有害气体中毒的时效对患者预后的影响？方法根据42例有害气体中毒患者入院时间不同分为3组。A组：吸入有毒气体2～4h入院；B组：吸入有毒气体24h入院；C组：吸入有毒气体48h入院。对3组不同时间入院（患者入院时间是根据中毒症状出现早晚）的有害气体中毒患者应用HBO治疗效果进行对比分析。结果2～4h入院患者经及时HBO治疗效果明显好于24h和48h入院采用HBO治疗的患者，而且减少了并发症的出现，改善了预后，提高了治愈率。经，检验，治疗效果显效以．／zA组与C组／=30，P〈0．01，B组与C组χ2=11．25，P〈0．01有显著性差异。治疗效果好转以上A组与C组，=8．57，P〈0．01，B组与C组χ2=4．50，P〈0．05有显著性差异。表明HBO早期治疗（24h内）有害气体中毒疗效显著。结论对急性有害气体中毒的治疗，除积极进行对症支持疗法外，应早期应用HBO治疗。

Objective To study the effects of hyperbaric oxygen （HBO） on the toxic sufferer of deleterious gas including sulfur dioxide, fog of mix gas, carbon monoxide, etc. Methods 42 cases of toxic sufferer of deleterious gas were divided into three groups according as the time of being in hospital. A group ： the sufferers inbreathed deleterious gas after 2 -4 hours being in hospital, B group： the sufferers inbreathed deleterious gas after 24 hours being in hospital, C group ： the sufferers inbreathed deleterious gas after 48 hours being in hospital. 42 cases of toxic sufferer of deleterious gas were treated by HBO, and the clinical effects were ana- lyzed. Results A group＇s clinical effects are obversler than B group and C group, it can lower incidental disease, reform prognosis and improve cure rate. B group＇s clinical effects are obversler than C group. The study indicated that the clinical effects are obviously through being treated by HBO early. Conclusion The toxic sufferer of deleterious should be treated through HBO early, except opposite and suspensory therapeutics.
