Abstract

STUDY OBJECTIVE: To compare guideline-based fluid resuscitation and need for respiratory support escalation in septic patients with pulmonary hypertension (PH) to those without PH.

DESIGN: Single-center, retrospective cohort study.

SETTING: Tertiary care academic medical center in Detroit, Michigan.

PATIENTS: Adult patients with or without PH hospitalized and diagnosed with sepsis from November 1, 2013 through December 31, 2019. Patients with sepsis were assigned to one of two groups based on a previous PH diagnosis or no PH diagnosis.

INTERVENTION: None.

MEASUREMENTS AND MAIN RESULTS: The primary outcome was incidence of respiratory support escalation within 72 h from sepsis time zero. Respiratory support escalation included high-flow nasal cannula, bilevel positive airway pressure, or intubation. One-hundred and four patients were included with 52 patients in each study group. Patients with PH were more likely to require escalation of respiratory support compared to non-PH patients (32.7% vs. 11.5%; p = 0.009). Fewer patients with PH received 30 mL/kg of crystalloid within 6 h of time zero compared with non-PH patients (3.8% vs. 42.3%; p < 0.001). Vasopressor initiation was more common in patients with PH compared with the non-PH group (40.4% vs. 19.2%; p = 0.018). PH diagnosis was the only independent predictor of respiratory support escalation.

CONCLUSIONS: During initial sepsis management when compared with patients without PH, patients with PH had increased instances of respiratory support escalation within 72 h of sepsis time zero despite lower fluid resuscitation volumes.
