OBJECTIVES This study was designed to investigate the effect on skin temperature of different methods of use of a hydrogel dressing. METHODS Twelve volunteers had temperature measured under a hydrogel dressing with different combinations of air movement and bandaging. RESULTS A large drop in skin temperature was only achieved when the dressing was left exposed with air movement over the sur...

Aerospace design engineers have long sought concrete data with respect to the thermal safety of materials in contact with human skin. A series of studies on this subject has been completed and some of the results have been reported earlier. In these studies over 2,000 observations were made of pain threshold during contact with materials at elevated temperatures. Six materials were used represe...

Background. Nd:YAP laser is widely used to investigate the nociceptive and pain systems, generating perpetual and laser-evoked neurophysiological responses. A major procedural concern for the use of Nd:YAP laser stimuli in experimental research is the risk of skin damage. The absorption of Nd:YAP laser stimuli is greater in darker skin, or in pale skin that has been darkened with ink, prompting...

BACKGROUND AND OBJECTIVES Epidural anesthesia decreases the core temperatures triggering vasoconstriction and shivering, presumably by increasing apparent (as opposed to actual) lower-body temperature. We therefore tested the hypothesis that epidural anesthesia also increases the overall perception of warmth. METHODS We studied 8 volunteers in a randomized, cross-over protocol separated by at...

The selective 5-hydroxytryptamine2-(5-HT2)-receptor-blocking agent ketanserin was given in a dose of 10 mg intravenously to nine patients with Raynaud's phenomenon. The effect on blood flow was assessed by photopletysmography and measurments of skin temperature. Digital blood flow and skin temperature increased significantly after ketanserin injection, whereas the placebo (saline 9 g/l) had no ...

Thermoregulatory mechanisms are remarkably efficient, ensuring minimal temperature variation within the core of the human body under physiological conditions. Diverse afferent and efferent neural pathways contribute to the monitoring of core and skin temperature, generation of heat, and control of thermal exchange with the external environment. We have investigated the cortical, thalamic, and h...

OBJECTIVE To evaluate the effects of local application of ice chips, ligno-paraffin, short-wave diathermy, and nitrogen-cold air on skin and intraarticular temperature. METHODS Forty-two healthy subjects were divided into 4 treatment groups. A temperature probe was inserted into the knee joint cavity and another placed on the overlying skin, and changes in temperature over 3 hours, by treatme...

Reaction time for warmth and cold sensation with 2°e, 5°e and s-e respectively above and below skin temperature had been found out in S students on left hand hypothener eminence and dorsum of middle phalanx of the middle finger with average threshold temperature of 2°e above and below skin temperature. The reaction time was found to be 0.66 sec. On increasing the difference of test temperature ...
