Chapter 44 Bladder Aspiration—Suprapubic Tap
Common indications
The suprapubic tap provides an excellent option for obtaining a sterile urine sample when a catheterization is not successful. It is most commonly performed in infants but could be done on any patient with a full bladder, requiring a sampling of urine (Figure 44-1).
Key steps
1. Preparation: Secure the infant in a frog-leg position to allow for easy access to the suprapubic area. Palpate the bladder, although it may not be palpable in a distressed infant. Cleanse the skin with Betadine, and drape the area around the pubis. Placing a urine bag on the infant is advisable, in case the child urinates during the procedure (Figure 44-2).
