Trial Outcomes & Findings for Effects of Intravenous Acetaminophen on Body Temperature and Hemodynamic Responses in Febrile Critically Ill Adults (NCT NCT01869699)

NCT ID: NCT01869699

Last Updated: 2017-08-09

Results Overview

time-weighted average core body temperature over 4 hours. Core temperature was measured every 5 minutes times 4, and then every 15 minutes over the following 4 hours from the time of study drug administration. The sum of the core temperature values was divided by time in minutes.
