Techniques to Stimulate Complete Bladder Emptying Si l

Bl dd E
i
1. A "trigger" can initiate a bladder contraction.
gg
○ Common method is called "suprapubic tapping“
– Drumming the abdomen overlying the bladder rapidly
7 or 8 times, stop 3 seconds, and repeat. – Application of rhythmic tapping to produce summation effect on the tension receptors in the bladder wall and
effect on the tension receptors in the bladder wall and activation of the reflex arc via the afferent discharges ○ Other trigger mechanisms include: Other trigger mechanisms include:
– Pulling pubic hairs
– Stroking abdomen or inner thigh – Digital anal stimulation. Voiding Maneuvers (continued)
Voiding Maneuvers 2. Double Voiding g
○ Involves urinating twice during each trip to the bathroom to reduce residual urine volumes. ○ Instruct patient to
– Urinate
– Remain on the toilet or stand up
– Attempt to urinate again after a rest period
of several minutes.
Voiding Maneuvers (continued)
Voiding Maneuvers 3. Crede Maneuvers ○ Mean of direct manual compression to empty an atonic or flaccid bladder
– Press firmly with one hand (or both hands) directly into the abdomen over s the bladder ○ Aims to ↑ intravesical pressure to enable/facilitate bladder emptying ○ Can facilitate urination if sphincter
mechanism is not in spasm
Intermittent Catheterization (IC)
