author = "Jeng, \{Eric I-Hun\} and Nikolaus Gravenstein and Klodell, \{Charles T.\}",
note = "Endoscopic thoracic sympathectomy (ETS) is indicated for refractory hyperhidrosis. The pulse oximetry-derived perfusion index (PI) quantifies pulsatile blood flow at the oximeter. Thoracic sympathectomy increases blood flow; thus we postulate it will reliably increase PI. We evaluated the ipsilateral finger PI as a predictor of successful sympathectomy during ETS.After institutional review board approval and informed consent, 100 adult patients undergoing bilateral ETS were studied.",
