It’s still dark outside as I, a rising second-year medical student, make my way through the doors of the hospital. After changing into my scrubs, I head over to the pre-operative area in search of my preceptor. Along with the third-year resident, I find my preceptor at the patient’s bedside. My preceptor points to the ultrasound, which shows the patient’s narrowed, abnormal artery. They already completed the pre-operative debrief and have begun physically preparing the patient for surgery. As the central line is placed, the patient moans.
