Observation on the efficacy of continuous veno-venous hemodia-filtration combined with hemoperfusion HA380 in the treatment of 15 cases of heat stroke with multiple organ dysfunction syndrome
Objective To investigate the clinical efficacy of continuous veno-venous hemodia-filtration(CVVHDF)combined with hemoperfusion(HP)HA380 in the treatment of heat stroke patients with multiple organ dysfunction syndrome(MODS).Methods A retrospective and observational study was conducted.A total of 15 patients with heat stroke combined with MODS who were admitted to the department of intensive care unit(ICU)of Suizhou Central Hospital/Hubei University of Medicine from July to September 2022 were selected as the study objects.All 15 patients were treated with CVVHDF combined with HA380 based on the comprehensive management strategy for severe illness.Organ function indicators[including total bilirubin(TBil),aspartate aminotransferase(AST),creatine kinase(CK),lactate dehydrogenase(LDH),creatinine(Cr),cardiac troponin T(cTnT),myoglobin(Myo),MB isoenzyme of creatine kinase(CK-MB),sequential organ failure assessment(SOFA)]and inflammatory indicators[including white blood cell count(WBC),neutrophil count(NEU),C-reactive protein(CRP),procalcitonin(PCT),and interleukin-6(IL-6)]were collected.The improvements of the above indexes at admission,after the first HP,after the second HP,after the third HP,and on the 5th day of treatment were compared.Combined with the clinical outcome of patients,the comprehensive efficacy of CVVHDF combined with HA380 in the treatment of severe heat radiation disease was evaluated.Results There were 10 males and 5 females among the 15 patients.The average age was(64.5±11.5)years old.There were 6 cases of classical heat stroke and 9 cases of exertional heat stroke.Glasgow coma scale(GCS)was 3-8 at admission;SOFA score was 9-17 within 12 hours after admission;acute physiology and chronic health evaluation Ⅱ(APACHEⅡ)was 25-45 within 24 hours after admission.After treatment,the IL-6 level and SOFA score gradually decreased,and there were significant differences in the decrease after the second HP compared to admission[IL-6(ng/L):48.37(15.36,113.03)vs.221.90(85.87,425.90),SOFA:8.3±3.3 vs.11.1±2.4,both P<0.05].The PCT level reached its peak after the first HP[12.51(6.07,41.65)μg/L],and then gradually decreased,and the difference was statistically significant after the third HP[1.26(0.82,5.40)μg/L,P<0.05].Compared those at admission,Cr level significantly improved after the first HP(μmol/L:66.94±25.57 vs.110.80±31.13,P<0.01),Myo significantly decreased after the second HP[μg/L:490.90(164.98,768.05)vs.3000.00(293.00,3000.00),P<0.05],After the third HP,the CK level also showed significant improvement[U/L:476.0(413.0,922.0)vs.2107.0(729.0,2449.0),P<0.05].After CVVHDF combined with 3 times HP treatment,the patient's inflammatory response was gradually controlled and organ function gradually recovered.On the 5th day of the disease course,WBC,PCT and IL-6 levels were significantly improved compared to admission,and AST,CK,LDH,Cr,Myo,CK-MB,and SOFA score were significantly corrected compared with those on admission.The 24-hour survival rate of 15 patients was 86.67%,and the 24-hour,7-day and 28-day survival rates were both as high as 73.33%.The average mechanical ventilation time of 11 surviving patients was(101.8±22.0)hours,the average continuous renal replacement therapy(CRRT)time was(58.8±11.0)hours,the average length of ICU stay was(6.3±1.0)days,and the average total hospitalization was(14.6±5.2)days.Conclusion CVVHDF combined with HP HA380 in the treatment of heat stroke patients with MODS can effectively improve organ function and alleviate the inflammatory storm,which is an effective means to improve the rescue rate and reduce the mortality of severe heat stroke patients.
