Fluid resuscitation of at least 30 mL/kg was not associated with decreased mortality in patients with infection, signs of hypoperfusion, and a do‐not‐intubate order

Abstract

Aim Administration of at least 30 mL/kg of fluid as fluid resuscitation is recommended for patients with sepsis and signs of hypoperfusion. However, it is not clear whether this is appropriate for patients with a do‐not‐intubate (DNI) order. This study evaluated the association between volume of fluid resuscitation and outcomes in patients with infection, signs of hypoperfusion, and a DNI order in an emergency department. Methods This was a single‐center retrospective cohort study. We classified the infected patients with signs of hypoperfusion and a DNI order seen in our emergency department between April 1, 2015 and November 31, 2020 into the standard fluid resuscitation group (≥30 mL/kg) and the restricted fluid resuscitation group (<30 mL/kg). We compared with in‐hospital mortality and the rate of discharge to home in two groups. Results Of 367 patients, 149 received standard fluid resuscitation and 218 received restricted fluid resuscitation. In‐hospital mortality was similar in each group (40/149 and 62/218, respectively). Standard fluid resuscitation was not associated with in‐hospital mortality (adjusted odds ratio [aOR], 1.05; 95% confidence interval [CI], 0.62–1.77, P = 0.86), but was associated with a significantly lower rate of discharge to home (aOR, 0.55; 95% CI, 0.30–0.98, P = 0.043). There was no significant difference in respiratory rate or need for oxygen therapy post‐resuscitation between the two groups. Conclusion This study suggests that fluid resuscitation may be not beneficial for infected patients with signs of hypoperfusion and a DNI order. Further studies should be conducted on the options for resuscitation management for these patients.
