Hemodynamic changes in patients with influenza A after propacetamol infusion in the emergency department

To our knowledge this is the first study on the effect of intravenous propacetamol in the ED patients with influenza A infection. We hypothesized that the group with a significant reduction in BP could have higher sympathetic tone, consequently showing higher pre-infusion BPs and pulse rate. And there was no difference in post-infusion BPs because baroreflex homeostasis could compensate further decrease in BPs.
