Effect of sub-hypothermia blood purification technique in cardiac shock after valvular disease surgery.

Abstract：

:To observe the effect of sub-hypothermia (HT) blood purification technique in the treatment of cardiac shock after heart valve disease.The patients were randomly divided into normothermic (NT) continuous blood purification (CBP) group (NT group) and HT CBP group (HT group). Observe the cardiac index (CI), the oxygen delivery (DO2) and oxygen consumption (VO2) ratio, Acute Physiology and Chronic Health Evaluation III(APACHE III) score, multiple organ dysfunction syndrome (MODS) score, dynamic monitoring of electrocardiograph, blood loss with or without muscle tremors, intensive care unit stay, mechanical ventilation time, CBP time, and the cases of infection and mortality at 0 day, 1 day, 2 day, 3 day; all above indicators were compared between 2 groups.Ninety-five patients were randomly assigned into HT group (48 cases) and NT group (47 cases); there were no significant differences between the 2 groups for age, gender, pre-operative cardiac function, cardiothoracic ratio, and type of valve replacement (P > .05). There were no significant differences among the 1 day, 2 day, 3 day after recruited for CI, DO2/VO2 ratio, APACHE III score, MODS score (P > .05). But in HT group, DO2/VO2 ratio had been significantly improved after treatment for 1 day (2.5 ± 0.7 vs 1.8 ± 0.4, P = .024), and CI (3.0 ± 0.5 vs 1.9 ± 0.7, P = .004), APACHE III score (50.6 ± 6.2 vs 77.5 ± 5.5 P = .022), MODS score (6.0 ± 1.5 vs 9.3 ± 3.4, P = .013) also had been significantly improved after treatment for 3 days. In clinical outcomes, there were no significant differences between 2 groups for blood loss (617.0 ± 60.7 ml vs 550.9 ± 85.2 ml, P = .203), infection ratio (54.17% vs 53.19%, P = .341), the incidence of ventricular arrhythmia (31.25% vs 36.17%, P = .237), and muscle tremors (14.58% vs 8.51%, P = .346), while there were significant differences between 2 groups for intensive care unit stay (6.9 ± 3.4 days vs 12.5 ± 3.5 days, P = .017,), mechanical ventilation time (4.2 ± 1.3 days vs 7.5 ± 2.7 days, P = .034,), CBP time (4.6 ± 1.4 days vs 10.5 ± 4.0 days, P = .019), mortality (12.50% vs 23.40%, P = .024). But the incidence of bradycardia in HT group was much higher than the NT group (29.16% vs 14.89%, P = .029).HT blood purification is a safer and more effective treatment than NT blood purification for patients who suffered from cardiac shock after valve surgery.
