Key result
Core-to-peripheral temperature gradient fails to correlate with cardiac index or SVR in shocked patients.
Why the study?
The reliability of core/peripheral temperature gradient as an indicator of hemodynamic status in shock patients was uncertain.
Does the core/peripheral temperature gradient correlate with cardiac index or systemic vascular resistance in shocked patients?
Observational (n=26)
Does the core/peripheral temperature gradient correlate with cardiac index or systemic vascular resistance in shocked patients?
The core/peripheral temperature gradient does not correlate with cardiac index or systemic vascular resistance and should not be used to guide therapy in shocked patients.
Answers are grounded in this paper and cite their sources.
Core-peripheral temperature gradient does not reflect CI or SVR in shock; challenges routine use and leaves open validation in prospective studies.
During the treatment of 26 shocked patients, measurements were made of the central blood to peripheral skin temperature gradient. No significant correlation was found between this gradient and cardiac index (CI), or systemic vascular resistance (SVR) or its index (SVRI). There was no significant correlation between the change in gradient and the changes in CI, SVR or SVRI in any single patient. We conclude that it is incorrect to base any judgment of a patient's hemodynamic status on a core/peripheral temperature gradient during shock, and it is irrational to initiate therapy based on this measurement.

Woods et al. (1987) conducted an observational in Shock (n=26). Core/peripheral temperature gradient was evaluated on Correlation with cardiac index (CI), systemic vascular resistance (SVR) or its index (SVRI). Core/peripheral temperature gradient showed no significant correlation with cardiac index or systemic vascular resistance in shocked patients.
