Noble Meta Alloy Coated Catheters in Patients With Long Term Catheterization
Noble Meta Alloy Coated Catheters in Patients With Long Term Catheterization
Eighty percent of nosocomial UTI caused by indwelling urinary catheters and so known-as
 catheter-associated UTI. CAUTI leads to multiple local and systemic derangements such as
 suprapubic pain, dysuria, cystitis, pyelonephritis, septicemia, and even septic shock.

 This study will be conducted up on 100 patients (50 per each group) with long term
 catheterization to assess efficacy of noble metal alloy coated catheter in reducing CAUTI.
This prospective controlled randomized study conducted upon 100 patients at Alexandria
 University hospital from 21 May 2020 to 21 December 2020. Patients enrolled will be divided
 into two equal groups according to the urethral catheter inserted

 The institutional ethics committee for research approved the study. Written informed consent
 was obtained from all participants. In addition to taking the patients' medical history and
 completing general and physical examinations, physicians will choose proper catheter size all
 perform catheterization using aseptic technique according to guidelines of proper aseptic
 catheterization. Urologist ensures comparable catheter size and amount of balloon inflation.

 An aseptic non-touch technique (ANTT) must be used to obtain catheter specimen urine
 following these steps:

 -  After catheterization apply clamp 10 cm distal to meatus then after few minutes clean
 the drainage port with alcohol and allow to dry then insert the syringe tip into the
 drainage port.

 -  Three to five ml of urine collected in sterile disposable plastic cup at day zero
 (within 2 hours of catheterization), day ten and day twenty post catheterization.

 -  The urine subjected to routine urine analysis, urine culture and sensitivity.

 Appropriate statistical tests will be used to indicate the frequency and type of CAUTI as
 well as to assess catheter tolerance in each arm, followed by a comparison to conclude the
 results.
