formed in theleft and right ventricular.Ventricular septal defect caused by bloodfrom left to rightshunt,resulting in abnormal hemodynamics.,病因(,Pathogeny),心血管畸形的发生主要由遗传和环境因素以及相互作用所致,Thecongenitalmalformationrelatestogeneticfactor,environmentalfactorortheinteractionof bothfactors.,1.早期宫内感染(,early intrauterine infection,),2.孕母有放射线接触和服用药物(,a radiationexposure and medications,),3.孕妇代谢紊乱性疾病(,metabolicdisorder disease,),4.妊娠早期酗酒、吸食毒品等,分类(,classification,),根据缺损的解剖位置不同,通长分为膜部缺损、漏斗部缺损和肌部缺损三大类。其中以膜部缺损最常见。绝大多数是单个缺损,偶见多个缺损。,According to the different anatomicaldefects usuallydivided intomembranedefect infundibular defect and muscular defectthree categories Themost common ismembranedefect.The vast majorityare singledefect,manydefects are rare.,病理生理(Pathophysiology),室间隔缺损时,左心室血流向右分流,分流量取决于两侧心室间的压力阶差、缺损大小和肺血管阻力。肺动脉压力随右心负荷增大而逐渐增高。,When the ventricular septal defects,theleft ventricular flowshunt,flow depends onthe pressureorderdifference between thetwo ventricles,defect sizeand pulmonary vascular resistance.The pulmonary arterialpressure gradually increases withright heart load.,临床表现(clinical manifestation,),症状(,symptom,),呼吸道感染,respiratory,乏力、多汗,Fatigue,sweating,气促、心悸,Shortness,、,palpitation,辅助检查(,laboratoryexaminations,),1、心电图(electrocardiogram):,小型,VSD,正常范围,大型,VSD,为左、右心室合并肥大。重度肺动脉高压时,显示双心室肥大、右心室肥大或伴劳损。,2、X线检查(,x-ray examination,),中度以上缺损时,心影轻到中度扩大,左心缘像左下延长,肺动脉段突出,重度梗阻性肺动脉高压时,肺门血管影明显增粗,甚至肺血管影呈残根征,3、,超声心动图(,echocardiogram,),示左心房、右心室内径增大。多普勒超声证实有左心室向右心室的分流。,治疗(treatment),1、缺损小、无血流动力学改变者,可暂观察,部分病例可自行闭合。,patient who defect is small or hemodynamic is not changeing,can temporarilyobservation,some cases canclose automatically.,治疗(treatment),2、缺损大、分流量大于50%或伴肺动脉高压的婴幼儿,应早期在低温体外循环下行心内直视修补术。,Defect ofinfants and young children,dividedflowis larger than 50%orwith pulmonary hypertension who should be earlyin the downlinkhypothermic cardiopulmonary bypass andopen heart surgery.,3、严重肺动脉高压、有右向左逆向分流者,禁忌手术。,patient who have a severe pulmonary hypertension,right to leftshuntoperationin reverse can not operate.,护理问题(Nursing problems,),术前(preoperative):,1、心输出量减少(decreased cardiac output),2、活动无耐力(activity intolerance),3、恐惧(fear),4、有感染的危险(risk of infection),5、知识缺乏(Lack of knowledge),术后,(postoperative,),:,1,、有心输出量减少的危险,(risk of decreased cardiac output,),2,、清理呼吸道无效(,cleartheairways,invalid,),3,、舒适度改变(,thechange of comfort,),4,、有皮肤完整性受损的危险,(impaired skin integrityis invalid,),5,、潜在并发症(,the potential complications,):肺高压危象、心律失常,护理措施nursing measures,术前(Preoperative),1、根据患者心功能情况指导患者适量运动,避免激动,紧张,活动间隙给予充分休息,增加患者的营养。,According tothe cardiac function of the patients,we should instruct them exercise,avoid excited and tension,make sure sufficient rest andincrease their nutritions.,2、护士应该热情接待患者,做好入院宣教,消除患者的陌生感。,Thenurse shouldrecept warmly,do a goodadmission education so that they,eliminate the strangeness.,3、病房开窗通风,患者注意保暖,减少人员探视,避免呼吸道感染。,we should ventilat windows in the ward,patientspay attention to keep warm,reduce personnel visit to preventrespiratory infection.,4、向患者及家属讲述术前的注意事项置管情况,并介绍手术室及监护室的一些情况。,Tell patient and their families about the attention tothe woundand catheter or somecondition about operation room and intensive care unit,术后(postoperative):,1、循环及意识的监测,密切观察患者生命体征,Monitoring of circulationandconsciousness,observe the vital signs closely,Heart rates,Blood pressure,Oxygensaturation,Respiration,2 保持呼吸道通畅,术后应用呼吸机辅助呼吸,保持患儿四肢温暖,促进末梢血液循环.,Keep airway clear,apply ventilator assisted breathing and keep warm to promote the blood circulation,3、采用体位引流,采取体疗促进痰液排出,遵医嘱用药,必要时进行吸痰。,take postural drainage

a comfortable posture,when is necessary givedrug at the doctors advice,.,5,、预防发生肺高压危象,prevent pulmonaryhypertension crisis,HOW?,(1)适当延长呼吸机辅助时间,防止发生肺部并发症,Prolongingventilation time appropriately prevent the occurrence ofpulmonary complications,(2)维持适当的过度通气。,Maintainhyperventilationappropriately,(3)应用降低肺动脉压的血管活性药物 Apply the vasoactive drugsto reducethe pulmonary artery pressure,(4)充分镇静,减少刺激。,keep calm,reducethestimulus,5、饮食与活动(,diet andactivity,),患者拔除气管4小时可饮水,进食流质饮食,若无呛咳,可改为普食。,Patient can trydrink water and fluid food when tracheal intubation werepulled outwithin four hours,if there isno cough,Instead of common food.,6、术后注意观察引流液的颜色、量、有无凝血块等。,Observe color,volume of thedrainage fluid,7、护患之间采取有效沟通,做好阶段性健康指导,指导家属正确认识疾病及正确照护患者,提高患者及家属的合作和依从性。,Effectivecommunicationbetween nurse and patient,make stagehealth guidance,give thema correct understanding of the diseaseandthe
