The purpose of this study is to describe infrared thermographic imaging as a tool for the assessment of epidural block in obstetrics patients
Patients will recive standard anesthesia care for epidural placement and additionally, thermographic imaging will be obtained at baseline and up to 30 min after the epidural blockade is performed.
