Background: To observe the skin temperature changes on the blocked area and its response to pinprick testing in ultrasound-guided transversus abdominis plane block (TAP block), and to explore the accurate predictor of the temperature measurement for TAP block success. Methods: A total of 30 patients underwent lower abdominal surgery were enrolled. Bilateral ultrasound-guided TAP blocks were per...

BACKGROUND CO2 lasers have been used for several decades as an experimental non-touching pain stimulator. The laser energy is absorbed by the water content in the most superficial layers of the skin. The deeper located nociceptors are activated by passive conduction of heat from superficial to deeper skin layers. METHODS In the current study, a 2D axial finite element model was developed and ...

OBJECTIVE Exercise induced hypotension is a specific but insensitive indicator of severe coronary artery disease. Skin blood flow is subject to control by baroreceptor mediated reflexes as well as thermoregulatory reflexes. Monitoring skin temperature or the skin to central temperature gradient may be a more sensitive indicator of impaired cardiac output response to exercise than hypotension. ...

OBJECTIVES To determine whether any difference exists in responses to indirect moxibustion (IM) relative to thermal stimulation duration. METHODS In experiment 1, 9 subjects attended two experimental sessions consisting of single stimulation with IM or triple stimulation with IM, using a crossover design. A K-type thermocouple temperature probe was fixed on the skin surface at the GV14 acupun...

The responses of two red grape varieties, Bovale Grande (syn. Carignan) and Cannonau (syn. Grenache), to temperature and natural UV radiation were studied in a three-years field experiment conducted in Sardinia (Italy), under Mediterranean climate conditions. Vines were covered with plastic films with different transmittances to UV radiation and compared to uncovered controls. Light intensity a...

BACKGROUND Tissue healing is an intricate process that is regulated by circulation. Heat modalities have been shown to improve skin circulation. Recent research supports that passive vibration increases circulation without risk of burns. Study purpose is to compare and determine effects of short duration vibration, moist heat, and a combination of the two on skin blood flow (SBF) and skin tempe...

The purpose of this paper is to improve the accuracy of the COMFA outdoor thermal comfort model for application to subjects performing physical activity. A sensitivity analysis was performed to identify conditions where the COMFA model produced erroneous estimates of the heat and moisture exchanges between the human body and the ambient environment, based on data from subjects performing modera...

BACKGROUND Circulation plays an essential role in tissue healing. Moist heat and warm water immersion have been shown to increase skin circulation; however, these heating modalities can cause burns. Recent research has shown that passive vibration can also increase circulation but without the risk of burns. MATERIAL/METHODS The aim of this study is to compare the effects of short-duration vib...

We tested the hypothesis that skin temperature, specifically of the head, is capable of modulating thermal behavior during exercise in the cold. Following familiarization 8 young, healthy, recreationally active males completed 3 trials, each consisting of 30 minutes of self-paced cycle ergometry in 6°C. Participants were instructed to control their exercise work rate to achieve and maintain the...
