Reminds me of the first week of my internship at Los Angeles County-University of Southern California Medical Center in July 1974. I needed to get an arterial blood gas from one of my patients — a drug addict with hepatitis and so-called "cannonball" fungal lesions in both lungs. I couldn't find the radial artery in either of his wrists, so I took the syringe and needle and moved down to his groin and tried a femoral stick. He was really obese and I couldn't feel his femoral pulse, so I tried to separate his abdominal fat pannus from his thigh with my right hand while plunging the needle into what I hoped would be his femoral triangle. The blind stick impaled my right index finger. My heart sank. I was sure I was gonna get hepatitis and/or his fungal infection, and spent the next month or so on tenterhooks waiting to wake up one day feeling sick. By some good fortune, I didn't get either of his illnesses.
