I always do, but only because I maintain an uptight and anxiety ridden attention to detail (not recommended). I expect 0 reflexes. However, the other day I had a patient who had had perfect BP's her whole pregnancy, but was in labor with an epidural in place for several hours and having BP's 160/90. When I checked her DTR's at her knees I got 2+ bilaterally. No other s/s of PIH, and after delivery her BP's started going down. Stress of delivery?? Who's knows.
Never thought of checking DTRs at the elbows, though. Thanks for the tip!
