摘要
目的 观察吸入一氧化氮对急性大面积和次大面积肺血栓栓塞症患者心脏功能和血浆心肌肌钙蛋白的影响,来探讨其对肺血栓栓塞症患者受损心脏的改善作用:方法 选择22例急性大面积和次大面积肺血栓栓塞症患者,随机分为2组,对照组11例,根据肺血栓栓塞症诊断指南要求溶栓抗凝常规治疗。治疗组11例在常规的基础上加入一氧化氮治疗,一氧化氮吸入浓度40×10^-6g/L,两组患者于治疗前、治疗后6、12、24、48小时采用彩色多普勒超声测量右心室心功能各项指标,并于治疗前、治疗后的前24小时每4小时和36、48小时抽血检测心肌肌钙蛋白。结果治疗组吸入一氧化氮后心功能指标[RVFDV(ml):90.1±44.2,RVESV(ml):50.6±34.4,SV(ml):44.1±11.9,RVEF(O):50.3±9.2,CO(L/min):3.91±0.7]于48小时改善明显高于对照组(RVFDV:100.1±46.2,RVESV:61.1±35.5,SV:38.3±8.6,RVEF:42.3±8.7,CO:3.29±0.86),P〈0.05,且于24小时即有明显改善(RVFDV:95.1±44.3,RVESV:63.6±36.4,SV:41.6±10.9,RVEF:45.6±9.1,CO:3.39±0.7),其心功能改善明显早于对照组(对照组24小时心功能参数RVFDV:106.1±46.2,RVESV:70.6±44.4,SV:36.7±9.2,RVEF:38.4±9.1,CO:2.99±0.81),P〈0.05,治疗组吸入一氧化氮后心肌肌钙蛋白峰值浓度(0.42±0.14)μg/L明显低于对照组(0.98±0.26)μg/L,P〈0.05且峰值出现时间(9.2±4.3)h明显早于对照组(12.6±6.4)h,P〈0.05。结论 吸入一氧化氮对大面积和次大面积肺栓塞患者受损心肌和心功能有明显的保护作用。
Objective To inquire into its ameliorative effect of nitric oxide inhalation on myocardial damage of pulmonary embolism, the cardiac function and cardiac troponin I of the patients with acute massive and submassive pulmonary embolism. Methods Twenty-two patients with acute massive and submassive pulmonary embolism were randomly divided into two groups. Control group.. 11 patients with conventional therapy by guideline of diagnosis and therapy of pulmonary embolism; treatment group: 11 patients with conventional therapy and nitric oxide inhalation of 40×10^-6 g/L. The changes in the right ventricular function indices were measured before treatment and after treatment 6 h,12 h,24 h,48 h and cardiac troponin I concentration was measured every 4 h for 24 h and at 36, 48 h after treetment. Results The right ventricular function indices after treatment [RVFDV(ml) : 90. 1± 44.2, RVESV(ml) : 50.6±34.4, SV(ml) ; 44.1±11.9,RVEF(%) .50.3±9.2 ,CO(ml) :3.91±0.7] were significantly higher in treatment group than those in control group (RVFDV.. 100.1 ± 46.2, RVESV.. 61. 1± 35.5, SV: 38.3±8.6, RVEF.. 42.3±8.7, CO..3.29±0.86), P 〈0.05, and the changes were markedly earlier in treatment group(RVFDV: 95.1 ±44.3,RVESV : 63.6± 36.4, SV: 41.6 ± 10.9, RVEF : 45.6± 9.1, CO: 3.39 ± 0.7), than those in control group (RVFDV:106.1±46.2,RVESV:70.6±44.4,SV:36.7±9.2,RVEF: 38.4±9. 1,CO:2.99±0.81), P 〈0.05,the peak concentration (μg/L)(0.42±0.14 vs 0. 98±0. 26, P 〈0.05) was obviously lower,and time of peak value occurred earlier in treatment group (9. 2±4.3) h than that in control group (12.6±6.4) h, P 〈0.05. Conclusions Nitric oxide inhalation could markedly ameliorate myocardial damage and cardiac function in the patients with massive and submassive pulmonary embolism.
