학습 자료 둘러보기 →The urethral meatus is the primary portal of entry for pathogens in patients with an indwelling urinary catheter. Localized redness and swelling at the insertion site indicates a breach in the mucosal barrier, allowing microorganisms to ascend.
Systemic signs like an elevated WBC count of 15,000/mm³ or localized symptoms like dysuria indicate infection progression, not the initial break at the portal of entry. Cloudy urine signifies colonization within the bladder reservoir.
Do not rely solely on urine appearance or systemic symptoms to identify a portal of entry break. Inspect the meatus-catheter junction daily for early signs of tissue damage or inflammation to interrupt the chain of infection at its source.
