Control the rate and volume of urine drainage in patients with urinary retention: Do not drain too quickly; clamp the catheter after draining 600-800ml. 3. Observe and record the color, amount, and nature of urine. Normal: 1500-2000ml/24h; Polyuria >2500ml/24h; Oliguria<400ml/24h; None <50ml/24h. Color: Normal: colorless and transparent or pale yellow; Abnormal: Hematuria, hemoglobinuria, bilirubinuria, chyluria. Secure the catheter properly, keep the tubing patent, and promptly check and adjust the catheter position if blocked. Repeatedly flush with nitrofurazone and replace if necessary. Prevent urinary tract infections. Daily bladder irrigation is unnecessary; urethral opening should be cleaned twice. Remove the catheter early when the condition is stable. Strictly adhere to aseptic techniques. Change the urine bag daily. For long-term indwelling patients, change the catheter weekly. Encourage patients to drink plenty of water during indwelling period. Bladder function training: Clamp the catheter daily, loosen it every 3-4 hours (except when using dehydrating agents). (Prevention of urethral bleeding and leakage: If the catheter is inserted too superficially, the balloon may adhere too closely to the posterior urethra, easily causing urethral bleeding. Therefore, after seeing urine, advance the catheter another 4-5 cm, inflate or inject water, and then gently pull the catheter outwards until it stops. At this point, the balloon is positioned at the internal urethral orifice, effectively preventing urethral bleeding or leakage. Post-prostatectomy and traumatic urethral rupture: Continuous irrigation for 2-3 days is necessary. In the early postoperative period, pay attention to the irrigation speed; too fast an irrigation can cause massive bleeding from the wound, while too slow an irrigation can cause internal bleeding to coagulate and form blood clots, hindering drainage.
Nuair a bhíonn an sreabhach draenála geal dearg, cuir leis an ráta drip chun an fhuil a shruthlú go pras, agus monatóireacht a dhéanamh ar athruithe brú fola ag an am céanna. Má chuireann téachtáin fola nó blúirí fíocháin bac ar an bhfeadán, fáisc an feadán le do mhéara. Má tá bac ort fós, cuir brú breise i bhfeidhm chun na clotanna fola a shruthlú agus a bhriseadh suas. I gcás othair máinliacht lamhnán, níor chóir go mbeadh an méid a instealladh gach uair níos mó ná 50 ml. Tar éis gach instealladh, ba cheart an toirt iomlán sreabhach uisciúcháin a tharraingt siar agus ansin a instealladh arís, ag athrá an phróisis uisciúcháin.)
