CBI

irrigation

(ir?i-ga'shon) [L. irrigatio, watering]
The cleansing of a canal or cavity by flushing with water or other fluids; the washing of a wound. The solutions used for cleansing should be sterile and, for comfort, have an approximate temperature slightly warmer than body temperature (100° to 115°F [37.8° to 46.1°C]). When irrigation is performed for bleeding, cold or iced irrigant may be used. Synonym: lavage See: gastric lavage

bladder irrigation

Washing out the bladder to treat inflammation or infection or to keep a urinary catheter flowing. The irrigation may be intermittent or continuous. Normal saline is commonly used.

Patient care

The necessary sterile equipment and the prescribed irrigant are assembled. The patient is covered with draping to preserve privacy and maintain antisepsis, and provided with information about how the procedure is done and what sensations will be experienced. A triple-lumen indwelling catheter is inserted into the urinary bladder via the urethra; placement is confirmed by the flow of urine, and the anchoring balloon inflated via its lumen. The prescribed volume of irrigant is instilled via the irrigation lumen; the catheter is clamped to allow the solution to remain in the bladder for the prescribed period of time; then the catheter is unclamped to allow the irrigant to flow out of the bladder via the drainage lumen by gravity into a collecting basin or closed drainage system. The irrigation is repeated the prescribed number of times. The character of the irrigation solution returned and the presence of any mucus, blood, or other material visible in the drainage is noted. The catheter is removed as per practitioner order. The time of the procedure, the type and volume of irrigant instilled, the type and volume of return, and the patient's response to the procedure are documented. If intermittent or continuous bladder irrigation is required, the catheter remains in place. Two large bags of irrigating fluid on a Y tubing are hung for continuous irrigation, with flow-rate controlled to maintain clear drainage. Urine output is determined by subtracting the amount of irrigant instilled from the total drainage obtained.

CAUTION!

Patients who receive high volumes of dilute fluids may absorb these irrigants and develop fluid overload or hyponatremia. To ensure patient safety, careful measurement of inputs and outputs and regular assessments of electrolytes, BUN, Cr, and oxygenation should be performed.

colonic irrigation

Flushing of the colon with water; an enema.
Synonym: colonic lavage

continuous bladder irrigation

Abbreviation: CBI
A constant flow of normal saline (or other bladder irrigant) through a three-way urinary catheter to keep the catheter patent. It is typically used postoperatively following a transurethral resection of the prostate gland.

Patient care

During CBI the volume of fluid infused and the volume returned is monitored and recorded.

high-pressure irrigation

Irrigation of a wound with sterile fluid at a pressure of 7.0 pounds per sq. inch.

joint irrigation

The flushing of a joint space with fluids to remove particles such as crystals or fragments of bone or cartilage. It may be used as a treatment for osteoarthritic joint pain.

low-pressure irrigation

Irrigation of a wound with sterile fluid at a pressure of 0.5 pounds per sq. inch.

nasal irrigation

Nasal lavage.

oral irrigation

Flushing of the mouth, teeth, and gums with fluids. This is done to remove plaque and to treat or prevent periodontal disease.

whole bowel irrigation

The administration of large volumes of a nonabsorbable fluid to remove potentially hazardous contents from the gastrointestinal tract. It is used to prepare some patients for bowel surgery and to decontaminate the gut after overdose.

continuous bladder irrigation

Abbreviation: CBI
A constant flow of normal saline (or other bladder irrigant) through a three-way urinary catheter to keep the catheter patent. It is typically used postoperatively following a transurethral resection of the prostate gland.

Patient care
