摘要
Purpose: Mortality rate for septic shock, despite advancements in knowledge and treatment, remains high. Treatment includes administration of broad-spectrum antibiotics and stabilization of the mean arterial pressure (MAP) with intravenous fluid resuscitation. Fluid-refractory shock warrants vasopressor initiation. There is a paucity of evidence regarding the timing of vasopressor initiation and its effect on patient outcomes. Materials and methods: This retrospective, single-centered, cohort study included patients with septic shock from January 2017 to July 2017. Time from initial hypotension to vasopressor initiation was measured for each patient. The primary outcome was 30-day mortality. Results: Of 530 patients screened,119 patients were included. There were no differences in baseline patient characteristics. Thirty-day mortality was higher in patients who received vasopressors after 6 h (51.1% vs 25%, p < .01). Patients who received vasopressors within the first 6 h had more vasopressor-free hours at 72 h (34.5 h vs 13.1, p = .03) and shorter time to MAP of 65 mmHg (1.5 h vs 3.0, p < .01). Conclusion: Vasopressor initiation after 6 h from shock recognition is associated with a significant increase in 30-day mortality. Vasopressor administration within 6 h was associated with shorter time to achievement of MAP goals and higher vasopressor-free hours within the first 72 h. (C) 2019 Elsevier Inc. All rights reserved.
