“…Interestingly, in another study these authors found that blinded observers were able to predict lateral infraclavicular block success with a sensitivity of 92% and a predictive value of 95% based on perceived temperature differences between the corresponding distal phalanges of the 2nd and 5th digits of the blocked and the contralateral hand, rendering it a valid and reliable diagnostic test for predicting successful lateral infraclavicular block . More recently, this group found that visual evaluation of thermographic patterns as well are useful for predicting successful lateral blocks in the clinical setting …”

Body temperature homeostasis is accurately regulated by complex feedback-driven neuronal mechanisms, which involve a multitude of thermoregulatory pathways. Thus, core temperature is constantly maintained within a narrow range. As one of the most effective regulatory systems skin temperature is dependent on skin blood flow. Skin blood flow in turn is highly dependent on sympathetic activity. Regional anaesthesia leads to blockade not only of somatosensory and motor nerve fibres but also of sympathetic fibres. As a consequence, vasoconstrictor tonic activity is abrogated and a vasodilation leads to an increase in skin blood flow and temperature. The aim of this review was to summarize the general physiology of thermoregulation and skin temperature as well as the alterations during regional anaesthesia. The main focus was the usefulness of measuring skin temperature as an indicator of regional anaesthesia success. According to the available literature, assessment of skin temperature can indeed serve to predict success of regional anaesthesia. Hence, it is important to realize that relevant and reliable temperature increase is only seen in the most distal body parts, ie fingers and toes. More proximally, temperature changes are frequently small and inconsistent, which means that assessment of block levels is not possible by temperature measurement. Furthermore, relevant skin temperature increases will only be observed in patients, which are initially vasoconstricted. In conclusion, measurement of skin temperature represents a reliable and feasible diagnostic tool to assess and predict the success or failure of regional anaesthesia procedures, especially in patients in which sensory testing is impossible.

“…2 Will real-time visualization of the onset of distal blocks lead to a similar future? The paper by Andreasen et al in this issue of the Journal on the visual assessment of thermographic patterns to predict the success of a lateral infraclavicular block (LIB) 3 gives us some food for thought.…”

“Eyeball test” of thermographic patterns for predicting a successful lateral infraclavicular block

Abstract: We conclude that visual evaluation by an eyeball test of specific thermographic patterns of the blocked hands may be useful as a valid and reliable diagnostic test for predicting a successful LIC block.
