Can A Catheter-Related Urinary Tract Infection?

618 Words3 Pages

Catheters are partially flexible tubes that collect urine from the bladder and leads into a drainage bag. They are often recommended by doctors if the patient is unable to control when they urinate, if they are leaking urine or if they’re unable to empty their bladder when they need to. These things can be caused by kidney stones, surgeries on various parts of the body, spinal cord injury and other conditions. (Cafasso J, 2015) Catheter-related urinary tract infection (UTI) occurs because urethral catheters inject organisms into the bladder and promote colonisation by providing a surface for bacterial adhesion and causing mucous related irritation (Brusch JL, 2015). The respective people at Flinders Nano-Scale took that information and created 2 coatings that could prevent the bacteria colonising on the catheters. These two coating are …show more content…

The first and most plausible reason is that because the catheters were bent almost 180 degrees to fit into the wells, the coatings and the outside of the catheters have possibly snapped and have begun to leak latex into the cells and killed them. This was highly likely and a few strategies were thought of to alleviate that problem in the future. If bigger wells were used, the catheters wouldn’t have been as bent and the coatings wouldn’t have snapped. Another possibly reason for the cells to die was the possibility of extra ethanol being added to the wells as the catheters were sterilised (in ethanol) before being placed into the wells. This however, wasn’t as plausible because after talking with another expert, she said that the amount of ethanol needed to kill the cells was not enough to kill the amount that it did. This brought up the thought that it was maybe enough to hinder the growth or stunt it slightly. This could be alleviated in the future by leaving the catheter pieces much longer than an hour to dry them properly and

I.V. fluids such as normal saline are utilized to increase volume and aid in the prevention of acute kidney injury. These I.V. fluids are initiated as soon as possible and are continued until the creatinine kinase level drops below 1,000 U/L. Diuretics such as Lasix are sometimes administered to promote the excretion of fluid. Bed rest is typically ordered for patients with rhabdomyolysis. In some cases, if compartment pressure exceeds 25 mm Hg, a fasciotomy and debridement may be

By installing a pneumatic delivery system, the hospital system could have the licensed caregivers focus more time on providing excellent care to our patients. There are some noted concerns that using a pneumatic tube system for laboratory specimen delivery may increase the risk of hemolysis in a blood sample (Lima-Oliveira et al., 2014). However, this risk of hemolysis does not pose a substantial harm to patients and is clinically insignificant in the vast majority of cases. This is particularly true in the case of the Alvin C. York Medical Center as the units that would utilize the pneumatic tube system are units that do not serve patients with acute medical conditions. The delay that currently exists due to the extended length of time it takes to transport a specimen from one side of the campus to the other is likely more of a detriment to patient care as the risk of hemolysis from rapid

During my clinical preceptorship at New York Presbyterian Hospital, many patients that came into the hospital with urinary retention a catheter was inserted to determine the amount of urine in their bladder or post-void residual (PVR). Many patients later developed pain and a urinary tract infection or Community Acquired Infection secondary to frequent cauterization. Therefore, the gap identified was related to a knowledge deficit of the current practice that inserting a

Staphylococcus epidermidis is the organism that was identified based on the tests that I had conducted. The tests that I used to identify this organism were the coagulase test and the catalase test. My bacterium was beta hemolytic as well. First, a gram stain had to be done to determine whether the organism was a gram positive organism or a gram negative organism. This determined which set of tests that had to be done.

If a sponge or an instrument fell on the floor it was washed and squeezed in a basin of tap water and used as if it were clean. Our silk to tie blood vessels was undisinfected.... The silk with which we sewed up all wounds was undisinfected. If there was any difficulty in threading the needle we moistened it with bacteria laden saliva, and rolled it between bacteria-infected fingers. We dressed the wounds with clean but undisinfected sheets, shirts, tablecloths, or other old soft linen rescued from the family ragbag.

In my facility, the safety of our patients is our top priority. We use a set of interventions using clinical indications to ensure the safety of patients with indwelling catheters. These indications are strict intake and output (I&O), patients monitored for acute renal insufficiency or failure, sedated patients with critical illness, and neurological patients monitored for syndrome of inappropriate antidiuretic hormone (SIADH) or diabetes insipidus. Patients suffering from acute urinary retention, or bladder outlet obstruction with the inability to void, as well as select surgical patients, are also indicated.

Some catheters come already lubricated, but if yours don't, you'll also need a supply of medical lubricant so you can insert the catheter without friction. You'll also need wipes to clean yourself first so you don't pass bacteria into your bladder. Gloves are not required, but you may want to wear them when you insert a catheter to help keep the catheter more sanitary, especially if you get urinary tract infections easily. In addition to the catheters, you may also want a bag if you can't get to a toilet easily.

Department of Health and Human Services established an objective for Healthy People 2020 to prevent HCAIs, this reflects that the U.S. health care system is committed to and serious about solving this issue. These objectives address two extremely important topics, central line-associated bloodstream infections, and methicillin-resistant Staphylococcus aureus (MRSA) infections. Also, there are other major causes of HCAIs that Health and Human Services is working on their prevention such as urinary tract infections (UTIs) associated with catheters, infections of surgical wounds and sites, C. difficile infections, and ventilator-associated Pneumonia. Researches done on HCAIs shown that we can prevent many of these infections by implementing effective strategies to eradicate it, adapting some advanced prevention tools, and following new prevention approaches. There should be a more focus on HCAIs prevention in acute care settings.

The challenge still lies in the severe under-reporting of urinary incontinence issues. After all, seniors cannot get help if nobody knows there is a problem. If your senior loved one may be having trouble with urinary incontinence, it is important that they have their situation investigated. A full third of overactive bladder issues may be linked to lower urinary tract infections. Not only could the bladder problem be quickly reversed with a UTI treatment, but the pain and discomfort of the UTI would be addressed as well.

In all areas of healthcare, particularly in acute care settings, patients may be unable to care for their nutritional and/or hygienic needs properly. One area that is especially important to address is the perineal care of patients who are incapacitated, or otherwise unable to care for their hygienic needs independently. Normal bacterial flora can develop into an opportunistic infection if the bacteria reaches certain areas of the body. For example, a common cause of urinary tract infections (UTI) is due to Escherichia coli from the colon coming into contact with the urethra (Copstead & Banasik, 2013). If the patient is immunocompromised, elderly, sedentary, or otherwise compromised in their abilities to void, this can predispose the patient
