【目的】探讨脓毒症患儿血清乳酸(lactic acid,LA)水平与其预后的关系。【方法】入住本院儿童重症监护病房(PICU)的脓毒症患365例,依据入住PICU 24 h内的血清 LA水平分为重度组(≥4 mmol/L)47例,轻度组(2 mmol/L≤LA<4 mmol/L)108例,正常组(<2 mmol/L)210例。分析血清 LA水平、6h乳酸清除率(lactate clearance rate,LCR)与脓毒症患儿严重程度和预后的相关性。【结果】LA重度组,轻度组及正常组并发严重脓毒症或脓毒性休克发生率分别为53.19%%、38.89%%、14.29%(P<0.05),并发多器官功能障碍综合征发生率分别为44.68%、33.34%和13.34%(P<0.05)。脓毒性休克组、严重脓毒症组和一般脓毒症组 LA水平分别为(4.00±3.85)mmol/L,(2.98±2.54)mmol/L,(1.85±1.52)mmol/L ,差异有统计学意义(H=38.55,P =0.000)。三组患儿的6 h后 LCR分别为(8.01±0.70)%,(12.34±15.89)%,(22.28±14.46)%,差异有统计学意义,(H=15.01,P=0.000)。随着时间延长,入院时、入院24 h及入院48 h其 LA水平呈下降趋势,差异无显著性(P>0.05)。生存患儿与死亡患儿入院时 LA水平分别为2.09±1.67 mmol/L,4.27±4.16 mmol/L,两组比较差异有统计学意义(u=4424.00,P=0.002)。低LCR组病死率明显高于高LCR组,差异有统计学意义(P<0.05)。【结论】动态监测脓毒症乳酸变化及乳酸清除率的变化有利于掌握病情变化及判断预后。
【目的】探討膿毒癥患兒血清乳痠(lactic acid,LA)水平與其預後的關繫。【方法】入住本院兒童重癥鑑護病房(PICU)的膿毒癥患365例,依據入住PICU 24 h內的血清 LA水平分為重度組(≥4 mmol/L)47例,輕度組(2 mmol/L≤LA<4 mmol/L)108例,正常組(<2 mmol/L)210例。分析血清 LA水平、6h乳痠清除率(lactate clearance rate,LCR)與膿毒癥患兒嚴重程度和預後的相關性。【結果】LA重度組,輕度組及正常組併髮嚴重膿毒癥或膿毒性休剋髮生率分彆為53.19%%、38.89%%、14.29%(P<0.05),併髮多器官功能障礙綜閤徵髮生率分彆為44.68%、33.34%和13.34%(P<0.05)。膿毒性休剋組、嚴重膿毒癥組和一般膿毒癥組 LA水平分彆為(4.00±3.85)mmol/L,(2.98±2.54)mmol/L,(1.85±1.52)mmol/L ,差異有統計學意義(H=38.55,P =0.000)。三組患兒的6 h後 LCR分彆為(8.01±0.70)%,(12.34±15.89)%,(22.28±14.46)%,差異有統計學意義,(H=15.01,P=0.000)。隨著時間延長,入院時、入院24 h及入院48 h其 LA水平呈下降趨勢,差異無顯著性(P>0.05)。生存患兒與死亡患兒入院時 LA水平分彆為2.09±1.67 mmol/L,4.27±4.16 mmol/L,兩組比較差異有統計學意義(u=4424.00,P=0.002)。低LCR組病死率明顯高于高LCR組,差異有統計學意義(P<0.05)。【結論】動態鑑測膿毒癥乳痠變化及乳痠清除率的變化有利于掌握病情變化及判斷預後。

[Obj ective]To explore the correlation between serum lactate level and the prognosis in children with sep-sis.[Methods]According to serum lactate level in pediatric intensive care unit(PICU)within 24h,365 children with sep-sis in PICU of our hospital were divided into severely elevated group (≥4mmol/L,n=47 ),mildly elevated group (2mmol/L≤lactate<4mmol/L,n=108)and normal group(<2mmol/L,n=210).The correlation of serum lactate level and 6h-lactate clearance rate with disease severity and prognosis of pediatric patients with sepsis was analyzed.[Re-sults]The incidence of severe sepsis or septic shock in severe lactate elevation group,mild lactate elevation group and nor-mal group was 48.54%,37.23% and 14.25%(P<0.05)respectively.The incidence multiple organ dysfunction syn-drome in 3 groups was 45.34%,32.15% and 13.67%(p<0.05)respectively.The lactate levels in septic shock group, severe sepsis group and general sepsis group were 4.00±3.851mmol/L,2.98±2.537mmol/L and 1.85±1.523mmol/L respectively,and there was significant difference(H=38.551,P=0.000).The 6h-lactate clearance rate of 3 groups was (8.01±0.703)%,(12.34±15.89)% and (22.28 ± 14.46)% respectively,and there was significant difference(H=15.008,P=0.000).Lactic acid was gadually decreased at admission,admission 24 hours and 48 hours of admission,but the difference was no statistically significant (P>0.05).Lactate level in survival group and death group on admission were 2.085±1.669mmol/L and 4.27±4.135mmol/L respectively,and there was significant difference(u=4424.00,P=0.002).Serum lactate levels of survival children at 1,2 and 3 days had the decreasing trend,while those of death or a-bandoned children had the increasing trend(P<0.05).The mortality in low lactate clearance rate group was obviously higher than that in high lactate clearance rate group,and there was significant difference(P<0.05).[Conclusion]The dynamic monitoring of the changes of lactate and lactate clearance rate is conducive to grasp the condition and prognosis of patients.
