Implication
Radial-femoral BP discrepancies during sweating may affect monitoring accuracy; leaves open thermoregulatory effects under anesthesia in patients.
Structured PICO
How do thermoregulatory and anesthetic-induced alterations affect the differences among femoral, radial, and oscillometric blood pressures in healthy volunteers?
P
Population
7 healthy volunteers
I
Intervention
Thermoregulatory changes (cooling until vasoconstriction, warming until intense sweating) and general anesthesia (propofol and N2O)
C
Comparator
Different thermoregulatory states (vasoconstriction vs intense sweating) and before/after hand blood flow occlusion
O
Outcome
Differences among femoral artery, radial artery, and oscillometric blood pressuressurrogate
Thermoregulatory and anesthetic-induced alterations in upper-extremity blood flow substantially influence the relations among femoral, radial, and oscillometric blood pressure measurements.
