[The value of determination of serum myoglobin in estimation of degree of illness and prognosis of patients with sepsis in Xining area].

OBJECTIVE: To investigate the value of determination of serum myoglobin (MYO) in estimation of the degree of illness and prognosis of patients with sepsis in Xining area. METHODS: Serum MYO was measured and acute physiological and chronic health estimationII (APACHEII) score was evaluated in 30 cases with sepsis within 24 hours of admission to emergency intensive care unit (EICU), and their correlation was analyzed. The patients were divided into two groups, survival group and death group according to the result within 28 days. The MYO and APACHEII score were analyzed in both groups. All cases were divided into three groups: namely <500 (n=10), 500-1 000 (n=14), >1 000 µg/L (n=6) groups, according to serum MYO value, and APACHEII score and dead case were compared among three groups. RESULTS: Sixteen patients survived, and 14 patients died. The level of serum MYO and APACHEII score were significantly lower in survival group than death group [MYO (µg/L): 607.85±499.40 vs. 976.21±370.10, APACHEII score: 15.50±4.43 vs. 18.93±3.63, t(1)=2.28, t(2)=2.29, both P<0.05]. With the elevation of serum MYO, the dead case was increased in sepsis patients (the dead case in MYO<500, 500-1 000, >1 000 µg/L groups was 2, 7, 5 cases, respectively,χ(2)=5.94, P<0.05), but there was no difference in APACHEII score among three groups. There was significant positive correlation between serum MYO and APACHEII score (r=0.407, P<0.05). CONCLUSION: Determination of serum MYO can reflect degree of illness and prognosis of sepsis patients in Xining area.
