目的

观察心肺超声联合指导的液体管理与目标导向治疗对脓毒性休克患者疗效的影响。

方法

选取2023 年3 月至2024 年12 月期间于遵义医科大学附属医院住院诊断为脓毒性休克的患者96例,按照随机数字表法随机分为心肺超声引导的液体治疗组(超声组)和目标导向治疗组(GDT组),每组48 例,其中男性59 例,女性37 例;年龄21~80 岁,中位年龄56.5(44.0,68.0)岁。收集患者入院时的基线资料,超声组患者分别于入组时(0 h),治疗后24、48 及72 h 行超声检查心脏收缩舒张功能、下腔静脉直径及其扩张指数和肺部情况引导液体治疗,GDT 组根据中心静脉压(CVP)、平均动脉压(MAP)、中心静脉血氧饱和度(ScvO2)、尿量、乳酸(Lac)联合指导液体管理,比较两组患者的基线资料、复苏液体量、NT-proBNP 变化情况,观察结局指标,包括24 h 复苏达标率、乳酸清除率(24、48 及72 h)、机械通气时间、ICU 住院时间、总住院时间、ICU 病死率、28 d 病死率。

结果

随着治疗时间延长,两组患者的心率和NT-proBNP 逐渐下降、MAP 均逐渐升高(P<0.05)。与GDT 组比较,心肺超声引导的液体复苏能提高24 h 复苏达标率,增加24、48 及72 h 乳酸清除率,减少24 及48 h 液体复苏量,增加48及72 h的出量、平衡量及尿量,加快NT-proBNP下降,但两组患者间机械通气时间、重症监护病房(ICU)住院时间、总住院时间、ICU病死率及28 d病死率比较差异均无统计学意义(P>0.05)。

结论

心肺超声可用于指导脓毒性休克患者的液体管理,提高24 h 复苏达标率和乳酸清除率,减少复苏液体量,使NT-proBNP明显下降,心肌损伤减轻。

Objective

To observe the impact of cardiopulmonary ultrasound - guided fluid resuscitation and goal-directed therapy on the prognosis of patients with septic shock.

Methods

A total of 96 patients diagnosed with septic shock hospitalized in Affiliated Hospital of Zunyi Medical University from March 2023 to December 2024 were selected and randomly divided into cardiopulmonary ultrasoundguided fluid therapy group (ultrasound group) and goal-directed therapy group (GDT group) according to random number table, with 48 patients in each group. Among them, there were 59 males and 37 females and the age ranged from 21 to 80 years, with a median age of 56.5 (44.0, 68.0) years. The baseline data of patients at admission were collected. The patients in the ultrasound group underwent critical care ultrasound examination, including cardiac systolic and diastolic function, inferior vena cava diameter and dilatation index, and lung condition at the time of admission (0 h), 24 h, 48 h and 72 h after treatment,respectively, to guide fluid therapy. GDT group guided fluid management according to central venous pressure (CVP), mean arterial pressure (MAP), central venous oxygen saturation (ScvO2), urine volume and lactic acid (Lac). Clinical data, fluid volume, NT-proBNP changes of the two groups were compared and prognostic indicators were observed, including 24-hour resuscitation targeting rate, lactate clearance rate(24 h,48 h,72 h),mechanical ventilation time,length of intensive care unit(ICU)and hospital stay,mortality within ICU and 28 days.

Results

With the prolongation of treatment, the heart rate and NT-proBNP of the two groups gradually decreased, and the MAP gradually increased (P<0.05). Compared with the GDT group,the fluid resuscitation guided by the cardiopulmonary ultrasound could increase the 24 h resuscitation targeting rate,increase lactate clearance rate at 24 h,48 h and 72 h,reduce the volume of fluid resuscitation at 24 hours and 48 hours, increase output, fluid balance and urine volume of 48h and 72 h, and accelerate the decline of NT-proBNP. There were no statistically significant differences in the time of mechanical ventilation, length of stay in ICU and hospital, mortality in ICU and 28 days between GDT group and ultrasound group (P>0.05).

Conclusion

Cardiopulmonary ultrasound can be used to guide the fluid treatment of patients with septic shock, improve the 24-hour resuscitation targeting rate and lactate clearance rate, reduce the infusion volume during resuscitation, significantly reduce NT-proBNP and therefore alleviate myocardial injury.
