ABSTRACT

Objective To study the clinical features of patients with hemorrhagic fever with renal syndrome(HFRS)complicating hyponatremia encephaledema and therapeutic effect of manicol and high sodium hemodialysis.Methods Eighty-three patients with HFRS complicating hyponatremia encephaledema were randomly divided into high sodium hemodialysis treatment group(n=41)and control group(n=42).The serum levels of potassium,sodium,chlorine,creatinine,osmotic pressure,normalization rates and normalization time of serum sodium,mortality of patients in two groups post-treatment were compared.Statistical analysis was performed using t test or chi square test.Resalts The serum levels of sodium [(128.95±7.3)mmol/L],chlorine[(96.7±6.2)mmol/L],osmotic pressure[(253.1±7.5)mOsm/L]of patients post-treatment in high sodium hemodialysis treatment group were all significantly higher than those[(117.8±7.1)mmol/L],[(92.2±6.9)mmol/L],[(242.1±8.4)mOsm/L]of patients in control group (t=7.14,t=3.12,t=15.22,respectively;all P＜0.05).The serum sodium normalization number of patients(12/19 cases)with moderate encephaledema in high sodium hemodialysis treatment group was significantly higher than that(6/19 cases)in control group(X2=3.867,P=0.049).The serum sodium normalization time of patients with moderate encephaledema in high sodium hemodialysis treatment group WaS(4.9±1.3)d,which was significantly shorter than that[(8.3±1.9)d]in control group(t=6.438,P=0.001).The serum sodium normalization number of patients(7/14 cases)with severe encephaledema in high sodium hemodialysis treatment group was significantly higher than that(2/14 cases)in control group(X2=4.094,P=0.043).The serum sodium normalization time of patients with severe encephaledema in high sodium hemodialysis treatment group was(7.8±1.9)d,which was significantly shorter than that[(11.6±2.8)d]in control group(t=3.235.P=0.034).The mortality in high sodium hemodialysis treatment group was 36.6%(15/41 cases),which was significantly lower than that(61.9%,26/42 cases)in control group(X2=5.321,P=0.021).Conclusions The conditions of patients with HFRS complicating hyponatremia encephaledema tend to be severe.In patients with HFRS complicating moderate or severe encephaledema,manicol and high sodium hemodialysis can improve the normalization rate and normalization time of serum sodium,and reduce the mortality.
