The Change Of Cardio Blood Flow Before And After The Surgery For Ventricular Septal Defect

Objective: To evaluate the changes of the size of each cardiac chamberand blood flow with the color ultrasonic doppler echocardiography in patientswith ventricular septal defect(VSD).If before surgery ventricular septal defectcombining with pneumonia can influence the changes.Methods: Collecting the patients from the1thto12thduring the year of2013who had been finished the cardiorrhaphy operation in the the medicallaboratory of Second Hospital, Hebei Medical University.These patients havebeen confirmed VSD with the Color ultrasonic doppler echocardiography.And the X-ray show increased pulmonary blood type of congenital heartdisease.The patients are between the ages of3moths and3years.It is14patients who combining with pneumonia.And the boy are9cases.The girl are5cases.It is18patients who don’t combining with pneumonia.And the boy are9cases.The girl are9cases.We had detected the size of each cardiac chamberand blood flow with the color ultrasonic doppler echocardiography before5days and after7days of the operation.The indicators are pulmonary artery(PA),aortic artery(AO), systolic peak velocity of pulmonary valve(Vpa), systolicpeak velocity of aortic valve(Vao), stroke volume(SV),ejection fraction(EF),before and after of the left ventricular end-diastolic diameter(LV), before andafter of the left auricular end-diastolic diameter(LA),before and after of theright ventricular end-diastolic diameter(RV),before and after of the rightauricular end-diastolic diameter(RV), interventricular septal thickness (IVS),left ventricular posterior wall thickness(LVPW),left ventricular end-diastolicvolume(EDV), left ventricular end systolic volume(ESV),the maximumvelocity of mitral valve mouth early diastolic E peak(Emv),and mitral valvemouth peak late diastolic blood flow to A peak speed(Amv).The changesamong these indicators before and after the surgery.And if the patients who combining with pneumonia have influence with these indicators.Result：1The changes among these indicator of color ultrasonic doppler echocard-iography who had been diagnosed VSD.The changes that before and after surger among these indicator: PA, AO,Vpa, Vao, SV, EF, CO, LA, LV, RA, RV, IVS, LVPW, EDV, ESV, Emv, Amv,E/A. If they have relationship with age, weight and sex.There are32cases. The boy is17.The girl is15.The average age is1.71±0.87years. The average weight is11.1±3.43kilo.The weight with EF hasthe relationship(P<0.05).The greater the weight,the higher EF.The other does’thave relationship with age, weight and sex(P>0.05).2The relationship between pneumonia before the surgery with the different ofweight, age and sex.The sex has no relationship with the pneumonia before the surgery(P>0.05).The age has no relationship with the pneumonia before the surgery(P>0.05).The weight has intimate relationship with the pneumonia before thesurgery (P<0.05).The greater the weight,the less risk to get pneumonia.3If the pneumonia before surgery have relationship with the changes of thesize of each cardiac chamber before and after surgery.3.1The changes of the left ventricle.LA is remarkable smaller after the surgery(P<0.01).The patient whodon’t have pneumonia are more smaller, but it dose’t have significance inStatistics (P>0.05).LV is remarkable smaller after the surgery(P<0.01).The patient who don’thave pneumonia are more smaller,but who have significance in Statistics(P>0.05).IVS is remarkable smaller after the surgery(P<0.01).The patient whodon’t have pneumonia are more smaller,but who have significance in Statistics(P>0.05). LVPW is more smaller after the surgery, but but it dose’t havesignificance in Statistics(P>0.05).AO has no remarkable changes between the before and after thesurgery(P>0.05).EDV is remarkable smaller after the surgery(P<0.01).The patient whodon’t have pneumonia are more smaller, but who have significance inStatistics (P>0.05).ESV is remarkable smaller after the surgery(P<0.01).The patient whodon’t have pneumonia are more smaller, but who have significance inStatistics (P>0.05).3.2The changes of the right ventricle.RV has no remarkable changes between the before and after the surgery(P>0.05).RA has no remarkable changes between the before and after the surgery(P>0.05).PA is remarkable smaller after the surgery(P<0.01).The patient who havepneumonia are more smaller, but who have significance in Statistics(P>0.05).4The changes of cardiac blood flow.E is remarkable smaller after the surgery(P<0.01).The patient who havepneumonia are more smaller, but who have significance in Statistics(P>0.05).A is remarkable smaller after the surgery(P<0.01).The patient who havepneumonia are more smaller, but who don’t have significance in Statistics(P>0.05).E/A has no remarkable changes between the before and after the surgery(P>0.05).Vpa is remarkable smaller after the surgery(P<0.01).The patient whohave pneumonia are more smaller, but who don’t have significance inStatistics (P>0.05).Vao is remarkable smaller after the surgery(P<0.01).The patient whohave pneumonia are more smaller, but who have significance in Statistics(P>0.05). CO is smaller than before the surgery, but it has no remarkable changesin Statistics (P>0.05).SV is remarkable smaller after the surgery(P<0.01).The patient who havepneumonia are more smaller, but who don’t have significance in Statistics(P>0.05).Conclusion:1Underweight children have more likely to pneumonia.2The changes are obvious in the size of each cardiac chamber and blood flowbefore and after the surgery.3It dose’t have obvious changes of the right ventricle before and after thesurgery.4It dose’t have obvious changes in the size of each cardiac chamber with thepatients who have pneumonia before the surgery.But they can influence thecardiac blood flow.5It is benefit to undergo surgery as early as possible for the patient who haspneumonia.
