RIVERA GARCIA, Alejandra  y  SANCHEZ VERGARA, Joaquín. Infrared pupillometry for monitoring transoperative analgesia in patients under general anesthesia. Acta méd. Grupo Ángeles [online]. 2016, vol.14, n.2, pp.69-76.  Epub 30-Ago-2021. ISSN 1870-7203.

Our aim is to establish if infrared pupillometry is useful to measure the analgesia level in patients under general anesthesia and to correlate the pupillometry values with the vital signs, the BIS and the opioid plasma concentration when the nociceptive stimulus is presented. Research: pilot, descriptive, prospective, with a non-probabilistic sample and consecutive assignation. A group of 20 women with breast cancer was recruited. All of them were scheduled for a radical mastectomy and an axillary dissection. Their vital signs and BIS were monitored. Balanced general anesthesia was applied with desflurane, and sufentanil and lidocaine infusions. We worked with the video pupillometer Neurolight Algiscan (Idimed). The first measurement was performed a minute after the first incision, and the second, at the axillary dissection. In both, the vital signs and the BIS values were recorded and the opioid concentration was calculated. Results were analyzed with a simple linear regression (Excel 2010).
