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.

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.

Trends in endotracheal intubation for patients with COVID-19 by emergency physicians.

Emergency physicians perform endotracheal intubations for patients with COVID-19. However, the trends in the intubation for COVID-19 patients in terms of success rate, complications, personal protective equipment (PPE) information, barrier enclosure use, and its transition have not been established. We conducted a retrospective study of COVID-19 cases that required tracheal intubation at four hospitals in the Tokyo metropolitan area between January 2020 and August 2021. The overall intubation success rate, operator experience, and infection control methods were investigated. We then compared the early and late phases of the pandemic for a period of 8 months each. A total of 211 cases met the inclusion criteria, and 133 were eligible for analysis. The intubation success rate increased from 85% to 94% from early to late phase, although the percentage of intubations performed by emergency medicine residents increased significantly in the late phase (p = 0.03). The percentage of light PPE use significantly increased from 65% to 91% from early to late phase (p < 0.01), whereas the percentage of barrier enclosure use significantly decreased from 26% to 0% (p < 0.01). Furthermore, the infection prevention methods during intubation became more simplified from early to late phase.
