Describe pre-opcare for a cystotomy

Blocked urethra = distend abdomen, post renal uraemia, hyperkalaemia

Hyperkalaemia can lead to cardiac arrhythmias, fluid and electrolyte imbalance

Mild to moderately dehydrated, 0.9% sodium chloride infused

Perioperative antibiotics

IV fluids to correct hydration and maintain normovolaemia

ECG trace

10

Describe surgical prep for a cystotomy

Catheterization of the bladder may be initially requested

Preparation of the abdomen for a midline incision

11

Describe how a cystotomy takes place

The bladder is located and exteriorized, via a midline incision

The abdomen is packed off prior to the incision being made into the bladder wall

Stay sutures are placed to assist with handling the bladder. The incision into the bladder is made on the ventral surface

Removal of a Bladder stone etc
