The PACU nurse need to be alert to the potential for urinary retention. The nurse should first encourage the patient to void independently. When the patient is unable to void, or voids in very small amounts, catheterization may be indicated. Accurate PVR is an assessment of the necessity of catheterization and discharged.
The PACU nurse must have a thorough understanding of urinary retention, and its causes, assessment, and potential effects on the patient’s recovery. With careful assessment and intervention, the PACU nurse can contribute to the patient’s comfort level, decrease the frequency of urinary retention, and develop long-term bladder function for the patient.
ECA: the use of diagnostic ultrasound as a monitor for urinary retention during bladder dysfunction due to spinal block. The use of a bladder catheter to prevent urinary retention is probably the safest method but it can provoke urethral damage and bladder infection. The cystometric studies can show the inter-individual duration of detrusor blockade by different drugs, by which the medical personnel would approximate implement the bladder catheterization. However the bladder scanner can follow up the increase of residual volume with a high percentage of success.
