“…Also, our results would be further strengthened by measuring Wnger blood Xow or forearm-Wnger temperature gradient. While the present results are based only on absolute Wnger skin temperature data, this parameter is the most commonly used measure for CIVD (Daanen 2003), while similar methods have been extensively used to measure Wnger perfusion (Sessler 2003). In conclusion, the results from the present experiment support that an association exists between T b and CIVD and that the triggering mechanism of CIVD is an increase in T b past a threshold.…”

Effect of body temperature on cold induced vasodilation

et al. 2008

Cold-induced vasodilation (CIVD) is an acute increase in peripheral blood flow observed during cold exposures. It is hypothesized to protect against cold injuries, yet despite continuous research it remains an unexplained phenomenon. Contrary to the traditionally held view, we propose that CIVD is a thermoregulatory reflex mechanism contributing to heat loss. Ten adults (4 females; 23.8 +/- 2.0 years) randomly underwent three 130-min exposures to -20 degrees C incorporating a 10-min moderate exercise period at the 65th min, while wearing a liquid conditioning garment (LCG) and military arctic clothing. In the pre-warming condition, rectal temperature was increased by 0.5 degrees C via the LCG before the cold exposure. In the warming condition, participants regulated the LCG throughout the cold exposure to subjective comfort. In the control condition, the LCG was worn but was not operated either before or during the cold exposure. Results demonstrated that the majority of CIVD occurred during the warming condition when the thermometrically-estimated mean body temperature (T (b)) was at its highest. A thermoregulatory pattern was identified whereby CIVD occurred soon after T (b) increased past a threshold (approximately 36.65 degrees C in warming and pre-warming; approximately 36.4 degrees C in control). When CIVD occurred, T (b) was reduced and CIVD ceased when T (b) fell below the threshold. These findings were independent of extremity temperature since CIVD episodes occurred at a large range of finger temperatures (7.2-33.5 degrees C). These observations were statistically confirmed by auto-regressive integrated moving average analysis (t = 9.602, P < 0.001). We conclude that CIVD is triggered by increased T (b) supporting the hypothesis that CIVD is a thermoregulatory mechanism contributing to heat loss.

“…As peripheral temperature may be influenced by ambient temperature, Tskin-diff may be a more reliable measurement, as the two skin temperatures are exposed to the same ambient temperature [14]. Experimental studies have suggested a Tskin-diff threshold of 08C for initiating vasoconstriction and of 48C for severe vasoconstriction [15,16]. Therefore, assessing skin temperature by touching the extremities or measuring a body temperature gradient can assist a physician to recognize a clinically acceptable CRT.…”

Clinical assessment of peripheral circulation

The feasibility and reproducibility of the clinical assessment of peripheral circulation are substantial, and reliance on capillary refill time, skin temperature, and mottling score must be emphasized and exploited. Incorporating therapeutic strategies into resuscitation protocols that aim at normalizing these peripheral circulation parameters are being developed to investigate the impact of peripheral perfusion-targeted resuscitation in the survival of critically ill patients.

“…This method has poor value in the setting of low room temperature and in distributive shock. (10) Near infrared spectroscopy To assess tissue consumption of oxygen in the muscles of the arm with NIRS, an area of stagnant ischemia is produced by constricting the arm with an inflatable cuff (to 260 mmHg), thus restricting blood flow to the hand. NIRS was used before, during and after inducing ischemia in healthy individuals.…”

Patients in cardiogenic shock (n=17), septic shock (n=14), without shock but with localized infection (n=14) and healthy volunteers (n=15) were included. Thenar StO2 was measured with NIRS before (baseline StO2, %), between (downward StO2 slope, %/min) and after 90 seconds of upper arm stagnant ischemia (hyperemic StO2, %). Muscle oxygen extraction (mOER) was calculated as follows: mOER (%) = (1-baselineStO2/hyperemic StO2)*100. Repeatability was assessed using the Bland Altman method (95 % of values within limits of agreement), comparing 55 pairs of measurements performed in 5-minute intervals. Repeatability of measurements was clinically acceptable. Compared to septic shock patients, cardiogenic shock patients had lower baseline StO2 (68.9 ± 10.0 % vs. 84.3 ± 10.4 %; p < 0.05) and hyperemic StO2 (80.8 ± 7.8 % vs. 91.8 ± 8.3 %; p < 0.05), and a higher downward StO2 slope (-17.4 ± 31.7 %/min vs. -9.1 ± 2.6 %/min; p < 0.05). mOER was higher in healthy volunteers (11.9 ± 3.8 %) and volunteers with cardiogenic shock (14.8 ± 7.3 %)
