Study Details
Study Description
Brief Summary
The aim of this study is to compare the peripheral perfusion index values produced by equi-MAC of sevoflurane and desflurane in patients undergoing single-agent inhalation anesthesia.

Detailed Description
Ether derivative anesthetics, including sevoflurane and desflurane, have direct activity on vascular tissue and both are vasodilators. However, there has been no direct comparison of vasodilative effect between sevoflurane and desflurane in vivo in humans. Peripheral perfusion index derived from photoplethysmographic waveform reflects peripheral vasomotor tone. Therefore, the purpose of this study is to compare the peripheral perfusion index values produced by sevoflurane and desflurane at equipotent concentration in patients undergoing single-agent inhalation anesthesia.
