Sepsis and septic shock are very common conditions among critically ill patients that lead to multiple organ dysfunction syndrome (MODS) and death. Our purpose was to investigate the efficacy of early administration of dexamethasone for patients with septic shock, with the aim of halting the progression towards MODS and death.
Prospective, randomized, double-blind, single-center study, developed in a surgical intensive care unit at Hospital das Clínicas, Faculdade de Medicina da Universidade de São Paulo.
The study involved 29 patients with septic shock. All eligible patients were prospectively randomized to receive either a dose of 0.2 mg/kg of dexamethasone (group D) or placebo (group P), given three times at intervals of 36 hours. The patients were monitored over a seven-day period by means of the sequential organ failure assessment score.
Patients treated with dexamethasone did not require vasopressor therapy for as much time over the seven-day period as did the placebo group (p = 0.043). Seven-day mortality was 67% in group P (10 out of 15) and 21% in group D (3 out of 14) (relative risk = 0.31, 95% confidence interval 0.11 to 0.88). Dexamethasone enhanced the effects of vasopressor drugs.
Early treatment with dexamethasone reduced the seven-day mortality among septic shock patients and showed a trend towards reduction of 28-day mortality.
脓毒症和脓毒性休克在重症患者中非常常见,可导致多器官功能障碍综合征(MODS)和死亡。我们的目的是研究早期给予地塞米松对脓毒性休克患者的疗效,以阻止病情发展至MODS和死亡。
前瞻性、随机、双盲、单中心研究,在圣保罗大学医学院临床医院的外科重症监护病房开展。
该研究纳入29例脓毒性休克患者。所有符合条件的患者被前瞻性随机分为两组,分别接受0.2mg/kg剂量的地塞米松(D组)或安慰剂(P组),每36小时给药一次,共给药三次。通过序贯器官衰竭评估评分对患者进行为期7天的监测。
在7天的观察期内,地塞米松治疗组患者需要血管升压药治疗的时间短于安慰剂组(p = 0.043)。P组7天死亡率为67%(15例中有10例),D组为21%(14例中有3例)(相对危险度 = 0.31,95%置信区间0.11至0.88)。地塞米松增强了血管升压药的作用。
早期使用地塞米松可降低脓毒性休克患者的7天死亡率,并显示出降低28天死亡率的趋势。
