This study evaluates the hemodynamic effects of the administration of 10% pentastarch solution (PS) during the initial treatment of hypovolemia in trauma patients. This prospective randomized phase II study included trauma patients admitted to the emergency room with hemorrhagic hypovolemia: systolic blood pressure (SBP) < 90 mmHg. Upon admission, the patients were randomized to receive 10% PS (n = 12) or isotonic 0.9% NaCl solution (IS) (n = 11), infused intravenously in 250-ml boluses, repeated until SBP > 100 mmHg. Blood pressure, infused volumes necessary to maintain SBP, and overall survival rates were determined and compared between groups. SBP increased significantly following either IS (from 64.4 +/- 9.2 mmHg to 111.1 +/- 6.3 mmHg), or PS (from 63.7 +/- 10.6 mmHg to 108.1 +/- 9.8 mmHg) when compared to admission values (p < 0.05). Endovenous volumes infused were greater (p = 0.001) in IS patients (1420 +/- 298 ml) than in PS patients (356 +/- 64 ml). No blood was transfused into PS patients, compared to 370 +/- 140 ml of red blood cells transfused into IS patients (p = 0.015). Mortality rates were similar in the two groups (p = 0.725). We concluded that PS is a safe, efficient method for inducing hemodynamic recovery of hypovolemic trauma patients, with a clear reduction in the intravenous volumes required for acute resuscitation.
本研究评估了在创伤患者低血容量初始治疗期间给予10% 羟乙基淀粉溶液(PS)的血流动力学效应。这项前瞻性随机II期研究纳入了因出血性低血容量而入住急诊室的创伤患者:收缩压(SBP)< 90 mmHg。入院时,患者被随机分为接受10% PS(n = 12)或等渗0.9% 氯化钠溶液(IS)(n = 11),以250 ml推注的方式静脉输注,重复进行直至SBP > 100 mmHg。测定并比较两组之间的血压、维持SBP所需的输注量以及总体生存率。与入院时的值相比,IS组(从64.4±9.2 mmHg升至111.1±6.3 mmHg)或PS组(从63.7±10.6 mmHg升至108.1±9.8 mmHg)的SBP均显著升高(p < 0.05)。IS组患者的静脉输注量(1420±298 ml)高于PS组患者(356±64 ml),差异有统计学意义(p = 0.001)。与向IS组患者输注370±140 ml红细胞相比,PS组患者未输注血液(p = 0.015)。两组的死亡率相似(p = 0.725)。我们得出结论,PS是诱导低血容量创伤患者血流动力学恢复的一种安全、有效的方法,可明显减少急性复苏所需的静脉输液量。
