Why the study?
Does fentanyl pretreatment impair the reliability of an epinephrine-containing test dose during propofol-nitrous oxide anesthesia?
Does fentanyl pretreatment impair the reliability of an epinephrine-containing test dose during propofol-nitrous oxide anesthesia?
Fentanyl pretreatment does not impair the reliability of an epinephrine-containing test dose during propofol anesthesia when using modified heart rate (≥10 bpm) or systolic blood pressure (≥15 mm Hg) criteria.
No takes yet. Share an insight, caveat, or question.
Supports reliable epinephrine test dose use during propofol anesthesia regardless of fentanyl; confirms no impairment by fentanyl in RCT.
