Initial fluid resuscitation (30 mL/kg) in patients with septic shock: More or less? - 30/11/21

Objectives |
The 2018 Surviving Sepsis Campaign (SSC) recommends rapid administration of 30 mL/kg crystalloid fluids for hypotension or lactate ≥4 mmol/L in patients with septic shock; however, there is limited evidence to support this recommendation. The purpose of this study was to examine the relationship between initial fluid resuscitation doses and prognosis in patients with septic shock.
Methods |
This was a multicenter prospective observational study of adult patients with septic shock who were admitted to four intensive care units (ICUs) in a total of three Jiangsu Province teaching hospitals over a 3-year span from May 8, 2018, to June 15, 2021. Each enrolled patients with septic shock was categorized into the low-volume (below 20 mL/kg fluid), medium-volume (20–30 mL/kg fluid) or high-volume (above 30 mL/kg fluid) fluid group according to the initial infusion dose given for fluid resuscitation. Various demographic attributes and other variables were collected from medical records. Logistic regression and Kaplan-Meier curve analysis were used to determine the relationship between initial fluid resuscitation doses and patient outcomes.
Measurements and main results |
A total of 302 patients who presented to the ICU were diagnosed with septic shock. The 28-day mortality was highest in the high-volume group (48.3%) and lowest in the medium-volume group (26.3%, P < 0.05). Patients who completed 30 mL/kg initial fluid resuscitation in the first 1–2 h had the lowest 28-day mortality rate (22.8%, P < 0.05). Logistic regression showed that a medium initial fluid volume dose was an independent protective factor, with the odds ratio (OR) indicating significantly decreased mortality (OR, 0.507; 95% confidence interval, 0.310–0.828; P = 0.007; P < 0.05). A Kaplan-Meier curve stratified by initial fluid resuscitation dose was constructed for the probability of 28-day mortality. The medium-volume fluid group showed a significantly lower 28-day mortality rate than the high-volume group or the low-volume group (log-rank test, P = 0.0016).
Conclusion |
In septic shock patients, an initial fluid resuscitation rate of 20–30 mL/kg within the first hour may be associated with reduced 28-day mortality; however, this result needs to be confirmed by further high-quality randomized controlled clinical trials.
