RÉSUMÉ

@#BACKGROUND: Septic shock causes life threatening organ dysfunction needing vasopressor despite adequate fluid resuscitation. Numerous studies and meta-analysis have proven norepinephrine as the initial vasopressor of choice in septic shock with vasopressin as add-on. Although guidelines have established the goal monitoring response in septic shock, optimal approach in discontinuation of the vasopressors in the recovery phase of septic shock remains limited. METHODS: A systematic review and meta-analysis was performed on randomized controlled trials (RCTs) and nonrandomized studies comparing incidence of hypotension within 24 hours of discontinuing norepinephrine first versus vasopressin. Three reviewers independently selected studies, assessed their quality, and extracted the following data: the number and characteristics of patients enrolled, inclusion and exclusion criteria for each study, the description of interventions (discontinuing norepinephrine first versus discontinuing vasopressin first) and outcomes (incidence of hypotension within 24 hours). RESULTS: Seven retrospective cohort studies and one prospective randomized control trial were included. Compared with norepinephrine, risk of hypotension is higher when vasopressin is discontinued first among patients in the recovery phase of septic shock (RR 2.06; 95% CI [1.11,3.82]; I 2 91%). Results were consistent in the subgroup analysis after excluding abstract-only and poor-quality studies (RR 1.73; 95% CI [0.74, 4.03]; I 2 93%). There is no difference in ICU (RR 0.97; 95% CI [0.71, 1.32]; I 2 38%) and in-hospital mortality (RR 0.88; 95% CI [0.66, 1.16]; I 2 41%) between the two vasopressor weaning strategies. Finally ICU length of stay was reported on 5 studies with no significant difference between the two strategies. CONCLUSION: Based on the results, there is increased risk of hypotension when vasopressin is discontinued first versus norepinephrine.
