简介:摘要目的对输血前A2/A2B亚型和RH弱D血型检测的意义进行探讨。方法选取2015年A型与AB型输血者分别5594人次与2207人次;2016年A型与AB型输血者分别6696人次与2578人次。对A2/A2B亚型、RH弱D血型检出率进行分析,并对两年间A型与AB型溶血性输血反应发生率、无效输血情况进行对比。结果溶血反应发生率方面,2015年为A型为0.045%、AB型为0.136%,2016年A型为0.089%、AB型为0.039%,2016年明显低于2015年,差异显著,有统计学意义,P<0.05。结论对A2/A2B亚型于输血前进行检测,对患者血型可更准确的进行判断,降低溶血性输血反应发生率,提高有效输血概率和输血安全性;通过RH弱D血型检测,可提高稀有血型患者输血安全性。

简介:摘要目的临床上脑卒中人群常可并发肺炎,肺炎严重影响人们生活甚至可致死亡.A2DS2评分可用于预测脑卒中人群是否会并发肺炎,对其预测效果进行临床分析.方法2014年9月我院根据相关临床经验和地区人群特点制定了特色型“A2DS2评分系统”,准备投入到临床应用中.现选取在我院就诊并诊断为脑卒中接受治疗的患者80例和相关负责医生20名,对80例脑卒中患者进行为期一年的随访.患者随访结果为“参照标准”,10名医生采用临床上常用预测方法对80例脑卒中患者预测的结果称为对照组.结果80例脑卒中患者调查结果显示,缺血性卒中最常见.观察组预测结果和“参考标准”相符程度(95.71%)与对照组相符程度(70.00%)相比明显较高;观察组医生满意度(90.00%)高于对照组满意度(60.00%),结果具有统计学意义(P<0.05).结论通过临床常用预测方法预测卒中后肺炎有一定的难度,新制定的A2DS2系统对于预测卒中后肺炎有重要作用,可以有效地提高预测的准确率,深受医生和患者好评,医生可以对患者临床预防进行专业指导,避免出现时治疗无效引起严重后果.关键词A2DS2评分;脑卒中;肺炎;预测价值ExploringtheforecastvalueofA2DS2scoreonconcurrencypneumoniaofpatientswithstrokeAbstractObjectiveStrokepatientsoftenaccompanypneumonia,pneumoniainfluencespeople’slifestrictlyandmayleadtodeath.A2DS2scorecanpredictifstrokepatientsoccurpneumonia,analyzeditsclinicaleffect.MethodWemade‘A2DS2ScoreSystem’accordingtoourhospital’srelatedclinicalexperienceanddistrict’sfeatures,itwasusedinclinical.Selected80patientswhowerediagnosedstrokeand20doctors,followed80patientsforoneyear.TheresultswasregarGdedas‘referencestandard’,80patientswhoacceptedroutineforecastmethodby10doctorswereselectedascontrolgroup;ResultThesurveyof80strokepaGtientsshowedthatischemicstrokewasthemostcommon.Thecorrespondbetweenforecastresultandtheresultof‘referencestandard’inobservationgroup(95.71%)washigherthan(70.00%)ofcontrolgroup;Thesatisfactiontodoctorsinobservation(90.00%)washigherthan(60.00%)ofcontrolgroup,theresultshadstatisticalsignificance(P<0.05).ConclusionClinicalroutineforecastmethodisdifficulttoforecastpneumonia,new-madeA2DS2systemhasimportanteffectonforecastingpneumonia,itcanincreasetheaccuracyeffectivelyandwelcomedbydoctorsandpatients,doctorscanprovideprofessionalguidanceforpatientstoavoidseriousKeryeswuolrtdbecauseofinvalidtreatment.A2DS2score;stroke;pneumonia;forecastvalue中图分类号R18文献标识码B文章编号1008-6315(2015)12-0256-01
