| 中文摘要 | 25位兒童經由心導管反核子醫學心臟血管攝影檢查分析給予高濃度氧氣前後血流動力學的變化。我們將此25位兒童分成三組,第一組8位,爲不具有左至右分流量的兒童,第二組9位,具左至右分流但無肺動脈高壓症第三組8位,同時具有左至右分流及肺動脈高壓症。研究結果,我們發現給氧之後在第一、二組其肺血管與體血管阻力比值無統計學差異(P >0.05),但在第三組則有明顯統計學差異存在(P<0.01),另外我們比較給高濃度氧後肺血管與體血管阻力減少率,發現第一組與第二組比較,無明顯統計學差異(P>0.05),但第一組與第三組比較,則有統計學差異(P<0.01) ,我們也以核子醫學心臟血管攝影方法評估肺血流量與體血流量比值的增加率,發現第一組與第二組及與第三組比較,均有統計學差異存在(P<0.01)。 |
| 英文摘要 | Twenty-five children were assessed by cardiac catheterization and first-pass nuclear angiocardiography (FPNA), first while breathing ordinary room air and then after breathing high concentration oxygen for 20 minutes. Among the 25 cases, group one included 8 children without left-to-right shunt; group two, 9 cases who had left-to-right shunts without pulmonary hypertension; group three consisted of 8 cases with left-to-right shunts and pulmonary hypertension. The total pulmonary resistance to total systemic resistance ratio (TPR/TSR) and pulmonary arteriolar resistance to total systemic resistance ratio (PAR/TSR) were calculated. No significant changes were found in groups one and two (P>0.05), but there was a significant change in group three (P<0.O1). Decreasing rates of TPR/TSR and PAR/TSR were measured after the patients breathed a high concentration of oxygen. There was no significant difference between groups one and two (P>0.05), but there was a significant difference between group one aid three (P0.01). Calculation by FPNA of the increased rate of pulmonary blood flow to systemic blood flow after breathing a high concentration of oxygen showed significant differences between group one compared with group two and three (P<0.01). |
