目的:總結氧療對穩(wěn)定期慢性阻塞性肺疾?。–OPD)患者肺功能及動脈血氣的影響情況。方法:2013年4月-2014年11月收治穩(wěn)定期COPD患者70例,隨機分成觀察組和對照組各35例,對照組給予常規(guī)治療方法,觀察組在對照組的基礎上增加氧療,氧氣流量控制在2 L/m in,連續(xù)氧療10 h,每天堅持氧療1次。結果:兩組患者治療前MMEF和FEV1比較差異無統(tǒng)計學意義(P>0.05);治療后兩組均明顯改善,與治療前比較差異有統(tǒng)計學意義(P<0.05);觀察組明顯優(yōu)于對照組,兩組治療后比較差異有統(tǒng)計學意義(P<0.05);兩組患者治療前PaO2和PaCO2比較差異無統(tǒng)計學意義(P>0.05);治療后,觀察組明顯優(yōu)于對照組,兩組比較差異有統(tǒng)計學意義(P<0.05)。觀察組臨床控制12例,顯效21例,有效1例,無效1例,總有效率97.1%;對照組臨床控制4例,顯效14例,有效10例,無效7例,總有效率80.0%,兩組比較差異有統(tǒng)計學意義(P<0.05)。結論:穩(wěn)定期COPD患者增加氧療可以明顯改善患者動脈血氣,提高血氧飽和度,臨床療效顯著,值得推廣。

2013年4月-2014年11月收治穩(wěn)定期COPD患者70例,隨機分成觀察組和對照組各35例,其中觀察組男20例,女15例,年齡52~82歲,平均69.9歲;對照組男21例,女14例,年齡52~88歲,平均71.5歲。兩組患者一般資料比較差異無統(tǒng)計學意義(P>0.05),有可比性。
方法:對照組給予常規(guī)治療方法,即給予支氣管擴張劑、祛痰藥及營養(yǎng)支持。觀察組在對照組的基礎上增加氧療,氧氣流量控制在2 L/min,連續(xù)氧療10 h,每天堅持氧療1次。
統(tǒng)計學方法:所有數(shù)據(jù)采用SPSS 16.0進行統(tǒng)計分析,計量資料用±s)表示,采用t檢驗;計數(shù)資料采用χ2檢驗;P<0.05為差異具有統(tǒng)計學意義。
兩組患者治療前后肺功能變化:兩組患者治療前MMEF和FEV1比較差異無統(tǒng)計學意義(P>0.05),治療后兩組均明顯改善,與治療前比較差異有統(tǒng)計學意義(P<0.05),觀察組明顯優(yōu)于對照組,兩組治療后比較差異有統(tǒng)計學意義(P<0.05),見表1。
兩組患者治療前后動脈血氣變化:兩組患者治療前PaO2和PaCO2比較差異無統(tǒng)計學意義(P>0.05),治療后,觀察組明顯優(yōu)于對照組,兩組比較差異有統(tǒng)計學意義(P<0.05),見表2。
兩組患者臨床療效比較:觀察組臨床控制12例,顯效21例,有效1例,無效1例,總有效率97.1%;對照組臨床控制4例,顯效14例,有效10例,無效7例,總有效率80.0%,兩組比較差異有統(tǒng)計學意義(P<0.05),見表3。
COPD發(fā)病的主要病理機制目前依然尚未完全清晰。但是從過往的研究中可以看出,該疾病的發(fā)生與多種誘發(fā)性的因素密切相關。例如空氣污染、吸入性的顆粒性污染物等,都會對患者的肺部支氣管遠端肺泡造成刺激和損傷,從而導致諸如肺部的肺泡、呼吸性細支氣管等組織出現(xiàn)硬化而失去彈性,功能性喪失等情況[1],此過程中往往伴隨著氣道的損壞,患者由于呼吸不暢所引起的一系列并發(fā)癥,例如營養(yǎng)不良、免疫力低下、呼吸衰竭等不良癥狀[2]。從動脈血氣上分析,患者的PaO2下降,PaCO2上升,動脈中的氧飽和度遠不足于維持組織的需要,患者出現(xiàn)缺氧狀態(tài),嚴重時還會造成生命危險。

Objective:To summarize the influence of oxygen therapy on the pulmonary function and arterial blood gas of COPD patients in stable stage.Methods:70 COPD patients in stable stage were selected from April 2013 to November 2014.They were random ly divided into the observation group and the control group with 35 cases in each.The control group was given routine treatmentmethod,and the observation group was given oxygen therapy on the basis of the control group.The oxygen flow was controled in 2 L/minutes,the continuous oxygen therapy 10 hours,insiston oxygen cure 1 time one day.Results:MMEF and FEV1 before treatment of patients in two groups were compared with no statistical significance(P>0.05);the two groups were significantly improved after treatment,itwas compared with before treatmentwith statistical significance(P<0.05);the observation group was significantly better than the controlgroup,the two groupsafter treatmentwere compared with statistically significant(P<0.05).PaO2and PaCO2before treatment of patients in two groups were compared with no statistical significance(P>0.05);after treatment,the observation group was significantly better than the control group,the two groups were compared with statistically significant(P<0.05).In the observation group,12 caseswere clinical control,21 cases were excellent,1 case was effective,1 case was invalid,the total effective rate was 97.1%.In the control group,4 caseswere clinical control,14 caseswere excellent,10 case was effective,7 casewas invalid,the totaleffective ratewas 80.0%.The two groupswere compared with statisticalsignificance(P<0.05).Conclusion:COPD patients in stable stage increased oxygen therapy can significantly improve the arterial blood gas of patients,improveblood oxygen saturation,the curativeeffectisobvious.It isworth promoting.
