One of the major determinants for survival of severely burned patients is appropriate fluid resuscitation. At present, fluid resuscitation is calculated based on body weight or body surface area, burn size, and urinary output. However, recent evidence suggests that fluid calculation is inadequate and that over- and under-resuscitations are associated with increased morbidity and mortality. We hypothesize that optimizing fluid administration during the critical initial phase using a transcardiopulmonary thermodilution monitoring device (pulse contour cardiac output [PiCCO]; Pulsion Medical Systems, Munich, Germany) would have beneficial effects on the outcome of burned patients.
A cohort of 76 severely burned pediatric patients with burns over 30% of the total body surface area who received adjusted fluid resuscitation using the PiCCO system were compared with 76 conventionally monitored patients (C). Clinical hemodynamic measurements, organ function (DENVER2 score), and biomarkers were recorded prospectively for the first 20d after burn injury.
Both cohorts were similar in demographic and injury characteristics. Patients in the PiCCO group received significantly less fluids (P<0.05) with similar urinary output, resulting in a significantly lower positive fluid balance (P<0.05). The central venous pressure in the PiCCO group was maintained in a more controlled range (P<0.05), associated with a significantly lower heart rate and significantly lower incidence of cardiac and renal failure (P<0.05).
Fluid resuscitation guided by transcardiopulmonary thermodilution during hospitalization represents an effective adjunct and is associated with beneficial effects on postburn morbidity.
严重烧伤患者生存的主要决定因素之一是适当的液体复苏。目前,液体复苏是根据体重或体表面积、烧伤面积和尿量来计算的。然而,最近的证据表明,液体计算是不充分的,过度和不足的复苏与发病率和死亡率的增加有关。我们假设在关键的初始阶段使用经心肺热稀释监测仪(脉搏轮廓心输出量[PiCCO];德国慕尼黑普逊医疗系统公司)优化液体管理,将对烧伤患者的预后产生有益影响。
将 76 例烧伤面积超过 30%总体表面积的严重烧伤儿科患者的队列与 76 例常规监测患者(C)进行比较。前瞻性记录烧伤后第 1 至 20 天的临床血流动力学测量、器官功能(丹佛 2 分)和生物标志物。
两组在人口统计学和损伤特征方面相似。PiCCO 组患者接受的液体量明显减少(P<0.05),尿量相似,导致正性液体平衡显著降低(P<0.05)。PiCCO 组的中心静脉压保持在更受控的范围内(P<0.05),与心率显著降低和心力衰竭和肾功能衰竭的发生率显著降低(P<0.05)相关。
住院期间通过心肺热稀释指导的液体复苏是一种有效的辅助手段,并与烧伤后发病率的降低有关。
