The order of female catheterization disinfection

When we undergo surgery or have physical problems, our body's excretion function may also be affected. For example, if someone has undergone appendectomy, before performing the appendectomy, we have to perform a series of anti-inflammatory processes on the patient. Anesthesia is also required during the operation. After anesthesia, people are basically unable to urinate and need catheterization. So, what is the order of female catheterization disinfection in this operation?

(1) Initial disinfection of the vulva: Instruct and assist the patient in cleaning the vulva. Wear a glove or finger cot on your left hand, hold a vascular clamp with a cotton ball filled with disinfectant in your right hand, and disinfect the mons pubis and labia majora in turn. Then use your left hand to separate the labia majora and disinfect the labia minora and urethral opening; place the dirty cotton balls and gauze in a curved tray; after disinfection, move the curved tray to the end of the bed.

(2) Open the catheterization bag between the patient's legs, use aseptic techniques to place a disposable catheter, urine collection bag, and another syringe into the bag, and pour disinfectant solution into a small medicine cup. Wear sterile gloves and spread a drape so that the drape and the inner wrap form a sterile area. Use a syringe to test whether the catheter is unobstructed and whether the balloon is leaking, and lubricate the front end of the catheter with a paraffin cotton ball.

(3) Disinfect the vulva again: Use your left hand to separate the labia minora, and use your right hand to clamp a cotton ball with disinfectant to disinfect the urethral opening, bilateral labia minora, and urethral opening from top to bottom. After wiping, keep your left hand fixed on the labia minora.

Things to note are:

1. Strictly implement aseptic operation: Replace the tube immediately if it is accidentally inserted into the vagina or falls out

2. Control the speed and volume of urination in patients with urinary retention: Do not urinate too fast, use a clamped tube of 600-800ml

3. Observe and record the color, quantity and properties of urine

(1) Normal: 1500-2000ml/24h Polyuria>2500ml/24h Oliguria<400ml/24h No urine<50ml/24h

(2) Color: Normal: colorless, transparent or light yellow; Abnormal: hematuria, hemoglobinuria, bilirubinuria, chyluria

(3) Fix the catheter properly and keep it normal. Check and adjust the position of the catheter in time if it is blocked. Rinse it repeatedly with furazolidone and replace it when necessary.

(4) To prevent urinary tract infection, it is not necessary to perform bladder irrigation every day. The urethral opening needs to be scrubbed twice. When the condition is stable, the catheter should be removed early and aseptic operation should be strictly followed. The urine bag should be changed every day. For those who have long-term catheterization, the catheter should be changed once a week. During the catheterization period, the patient is encouraged to drink more water.

(5) Bladder function training: Clamp the tube daily and loosen the tube every 3-4 hours (except when using dehydration drugs)

(6) Preventing urethral bleeding and urine leakage: If the catheter is inserted too shallowly, part of the balloon will be close to the posterior urethra, which may cause urethral bleeding. Therefore, the upper catheter should be inflated or filled with water after the urine enters 4-5 cm, and then the catheter should be gently pulled outward until it stops. At this time, the balloon is just at the inner opening of the urethra, which can effectively prevent urethral bleeding or leakage.

(7) Post-prostate surgery and traumatic urethral rupture: Flushing should be continued for 2 to 3 days. Pay attention to the flushing speed in the early postoperative period. Flushing too quickly may cause heavy bleeding from the wound, while flushing too slowly may cause internal bleeding to coagulate and form blood clots, making drainage difficult. When the drainage fluid is bright red, the dripping rate should be increased to flush out the blood in time, and the blood pressure changes should be observed at the same time. If blood clots or tissue fragments are blocking the tube, you can squeeze the tube with your fingers. If it is still not unobstructed, flush it with a certain pressure to break up the blood clot and discharge it. For patients undergoing bladder surgery, the injection volume should not exceed 50ml each time. After the flushing fluid is injected, it should be completely drawn out and then injected again, and flushed repeatedly.
