目的:探讨β受体阻滞剂对脓毒性休克患者的心脏保护作用及对血流动力学的影响。方法采用前瞻性随机对照研究方法,以2012年1月至2014年1月山东济宁医学院附属湖西医院重症监护病房(ICU)收治的6 h早期目标导向治疗(EGDT)达标的41例脓毒性休克患者为研究对象,并按随机数字表法将患者分为治疗组(21例)和对照组(20例)。两组均按指南继续治疗脓毒性休克,治疗组同时经上腔静脉用微量泵持续泵入艾司洛尔,2 h内控制心率(HR)<100次/min;对照组不予特殊干预。观察两组患者治疗前及治疗后12、24、48、72 h的血流动力学指标〔平均动脉压(MAP)、中心静脉压(CVP)、HR、心排血指数(CI)、每搏量指数(SVI)、外周血管阻力指数(SVRI)、全心舒张期末容积指数(GEDVI)〕、组织代谢指标〔中心静脉血氧饱和度(ScvO2)、乳酸(Lac)〕和心肌标志物〔心肌肌钙蛋白I(cTnI)〕的变化。结果①两组患者治疗前血流动力学指标、组织代谢指标及cTnI比较差异均无统计学意义(均P>0.05)。②与治疗前比较,对照组治疗后血流动力学指标无明显改变;治疗组治疗后HR、CI逐渐下降,SVRI、GEDVI逐渐增加,且12 h起即与对照组比较差异有统计学意义〔HR(次/min):93±4比118±13,CI(L·min-1·m-2):3.3±0.8比4.5±0.6,SVRI(kPa·s·L-1·m-2):159.2±27.4比130.5±24.2,GEDVI(mL/m2):668±148比588±103,P<0.05或P<0.01〕,而MAP、CVP、SVI均无明显改变。③两组治疗后Lac水平(mmol/L)均明显下降,12 h即与治疗前差异有统计学意义(对照组:8.8±3.2比9.8±3.4,治疗组:9.5±3.1比10.5±4.1,均P<0.05),72 h时两组分别为2.5±1.2和2.7±1.1;但两组间各时间点比较差异无统计学意义(均P>0.05)。两组治疗后ScvO2均无明显下降。④与治疗前比较,对照组治疗后cTnI逐渐升高,72 h达峰值;治疗组治疗后cTnI逐渐升高,24 h达峰值后逐渐下降。治疗组治疗后24、48、72 h时cTnI(μg/L)明显低于对照组(1.15±0.57比1.74±0.77、0.93±0.52比2.15±1.23、0.52±0.36比2.39±1.17,均P<0.01)。结论β受体阻滞剂艾司洛尔能改善脓毒性休克患者心脏顺应性,减轻心肌损伤,虽然能引起心排血量下降,但对循环功能及组织灌注无影响。
目的:探討β受體阻滯劑對膿毒性休剋患者的心髒保護作用及對血流動力學的影響。方法採用前瞻性隨機對照研究方法,以2012年1月至2014年1月山東濟寧醫學院附屬湖西醫院重癥鑑護病房(ICU)收治的6 h早期目標導嚮治療(EGDT)達標的41例膿毒性休剋患者為研究對象,併按隨機數字錶法將患者分為治療組(21例)和對照組(20例)。兩組均按指南繼續治療膿毒性休剋,治療組同時經上腔靜脈用微量泵持續泵入艾司洛爾,2 h內控製心率(HR)<100次/min;對照組不予特殊榦預。觀察兩組患者治療前及治療後12、24、48、72 h的血流動力學指標〔平均動脈壓(MAP)、中心靜脈壓(CVP)、HR、心排血指數(CI)、每搏量指數(SVI)、外週血管阻力指數(SVRI)、全心舒張期末容積指數(GEDVI)〕、組織代謝指標〔中心靜脈血氧飽和度(ScvO2)、乳痠(Lac)〕和心肌標誌物〔心肌肌鈣蛋白I(cTnI)〕的變化。結果①兩組患者治療前血流動力學指標、組織代謝指標及cTnI比較差異均無統計學意義(均P>0.05)。②與治療前比較,對照組治療後血流動力學指標無明顯改變;治療組治療後HR、CI逐漸下降,SVRI、GEDVI逐漸增加,且12 h起即與對照組比較差異有統計學意義〔HR(次/min):93±4比118±13,CI(L·min-1·m-2):3.3±0.8比4.5±0.6,SVRI(kPa·s·L-1·m-2):159.2±27.4比130.5±24.2,GEDVI(mL/m2):668±148比588±103,P<0.05或P<0.01〕,而MAP、CVP、SVI均無明顯改變。③兩組治療後Lac水平(mmol/L)均明顯下降,12 h即與治療前差異有統計學意義(對照組:8.8±3.2比9.8±3.4,治療組:9.5±3.1比10.5±4.1,均P<0.05),72 h時兩組分彆為2.5±1.2和2.7±1.1;但兩組間各時間點比較差異無統計學意義(均P>0.05)。兩組治療後ScvO2均無明顯下降。④與治療前比較,對照組治療後cTnI逐漸升高,72 h達峰值;治療組治療後cTnI逐漸升高,24 h達峰值後逐漸下降。治療組治療後24、48、72 h時cTnI(μg/L)明顯低于對照組(1.15±0.57比1.74±0.77、0.93±0.52比2.15±1.23、0.52±0.36比2.39±1.17,均P<0.01)。結論β受體阻滯劑艾司洛爾能改善膿毒性休剋患者心髒順應性,減輕心肌損傷,雖然能引起心排血量下降,但對循環功能及組織灌註無影響。

Objective To investigate the effects of β-blockers on cardiac protection and hemodynamic in patients with septic shock. Methods A prospective randomized controlled trial was conducted. Forty-one patients with septic shock in accordance with early goal directed treatment and met the target within 6 hours,and admitted to intensive care unit (ICU)of Affiliated Huxi Hospital of Jining Medical College from January 2012 to January 2014 were enrolled. The patients were divided into treatment group (n=21)and control group (n=20)by random number table. The patients in both groups were given the standard treatment,esmolol was giving to patients in treatment group in order to control the heart rate (HR)below 100 bpm within 2 hours,and the patients in control group only received standard treatment. The changes in hemodynamic parameters〔mean arterial pressure(MAP),central venous pressure(CVP), HR,cardiac index(CI),stroke volume index(SVI),systemic vascular resistance(SVRI),global end diastolic volume index(GEDVI)〕,biochemistry metabolic of tissue〔central venous oxygen saturation(ScvO2),lactic acid(Lac)〕,and cardiac markers 〔troponin I (cTnI)〕before and 12,24,48,72 hours after the treatment were recorded. Results①Before treatment,the hemodynamic parameters,tissue metabolism index and cTnI had no significant differences in both groups (all P>0.05).②The hemodynamic parameters after treatment in the control group showed no significant difference compared with that before treatment. HR and CI in the treatment group were gradually declined after treatment,SVRI and GEDVI were gradually increased. There were significant differences in HR,CI,SVRI,and GEDVI between treatment group and control group from 12 hours on〔HR(bpm):93±4 vs. 118±13,CI (L·min-1·m-2):3.3 ±0.8 vs. 4.5 ±0.6,SVRI (kPa·s·L-1·m-2):159.2 ±27.4 vs. 130.5 ±24.2,GEDVI(mL/m2):668 ±148 vs. 588 ±103,P<0.05 or P<0.01〕. MAP,CVP and SVI in the treatment group showed no significant changes. ③Lac after treatment in both groups was decreased slowly,Lac (mmol/L)at 12 hours after treatment was significantly decreased compared with that before treatment (control group:8.8 ±3.2 vs. 9.8 ±3.4,treatment group:9.5±3.1 vs. 10.5±4.1,both P<0.05). The Lac of control group and treatment group were 2.5±1.2 and 2.7±1.1 at 72 hours after treatment,and there was no significant difference between two groups (all P>0.05). The ScvO2 was not decreased in both groups.④Compared with before treatment,cTnI in the control group was gradually increased,peaked at 72 hours,and that in the treatment group was gradually increased,peaked at 24 hours and then gradually declined. Compared with control group,the cTnI (μg/L)in the treatment group was decreased significantly at 24,48,72 hours (1.15 ±0.57 vs. 1.74 ±0.77,0.93 ±0.52 vs. 2.15 ±1.23,0.52 ±0.36 vs. 2.39 ±1.17,all P<0.01). Conclusionsβ-blockers (esmolol) can improve cardiac function and myocardial compliance,reduce the myocardial injury in patients with sepsis shock. Although β-blockers can decrease cardiac output,it has no influence on the circulation function and tissue perfusion.
