Department of Health and Human Services erectile dysfunction prevention generic kamagra effervescent 100mg mastercard, Health Resources and Services Administration; 2004 erectile dysfunction treatment boston medical group cheap kamagra effervescent 100 mg without a prescription. If noninfectious causes are suspected erectile dysfunction drugs available in india purchase 100 mg kamagra effervescent fast delivery, perform evaluation for these etiologies as indicated erectile dysfunction at age 21 effective kamagra effervescent 100 mg. If the patient is febrile, perform a complete fever workup as appropriate (see chapter Fever). If all study results are negative but the diarrhea persists, repeat endoscopy in 6-8 weeks regardless of the level of immunodeficiency. The suggested dosage is 2 tablets after each loose bowel movement, not to exceed 8 tablets per day. These agents should not be used if patients have bloody diarrhea or if the presence of C. Patients with diarrhea related to protease inhibitors may find that taking calcium with each dose of protease inhibitors can decrease or prevent diarrhea. Avoid administering cholestyramine with other medications because it may impair their absorption. For seriously ill patients, presumptive treatment may be started while diagnostic tests are pending. Monitor effectiveness and adjust therapy according to the results of diagnostic studies and clinical response. Specific treatment with antimicrobials is guided by the pathogens identified in stool studies or on biopsy. Diarrhea owing to protease inhibitors often decreases after a few weeks without treatment. Nutrition and hydration Encourage frequent intake of soft, easily digested foods such as bananas, rice, wheat, potatoes, noodles, boiled vegetables, crackers, and soups. Encourage hydration with fruit drinks, tea, "flat" carbonated beverages, and water. Patients should avoid high-sugar drinks, caffeinated beverages, alcohol, high-fiber foods, greasy or spicy foods, and dairy products. Many patients may benefit from a trial of a lactose-free, Section 5: Common Complaints Diarrhea low-fiber, or low-fat diet. Patients should use nutritional supplements as needed or as recommended by a dietitian. In case of chronic or severe diarrhea, or significant weight loss, refer to a dietitian for further recommendations. Patients with severe diarrhea must maintain adequate hydration, by mouth if possible. Oral rehydration solutions include the World Health Organization formula, Pedialyte, Rehydralyte, Rice-Lyte, and Resol. Department of Health and Human Services, Health Resources and Services Administration; 2004;55-65. Instruct patients to notify their health care provider if they develop new or worsening symptoms. Instruct patients to eat small, frequent meals and to avoid dairy products, greasy food, and high-fat meals. Nasopharyngeal lymphoid hyperplasia, sinusitis, or allergies may contribute to dysfunction of the eustachian tubes. Perform visual and otoscopic inspection, including evaluation for skin abnormalities, lesions, cerumen impaction or foreign body, lymphadenopathy, and adenotonsillar hypertrophy. If hearing loss is reported or suspected, evaluate hearing and refer the patient for an audiogram. S: Subjective the patient may complain of ear pain, decreased hearing or hearing loss, a feeling of fullness in the ear, vertigo, or a popping or snapping sensation in the ear. Hearing Loss A patient with hearing loss should be referred for evaluation or treated, depending on the cause. Check the nasal mucosa with a light and a speculum, looking for areas of bleeding, purulent drainage, ulcerated lesions, or discolored areas. Palpate or percuss the sinuses for areas of tenderness, look for areas of swelling over the sinuses, and visualize the posterior pharynx for mucopurulent drainage. Check maxillary teeth with the use of a tongue blade (5-10% of maxillary sinusitis is attributable to dental root infection). S: Subjective the patient may complain of "stuffy nose," rhinorrhea, epistaxis, frontal or maxillary headaches (worse at night or early morning), pain in the nostrils, persistent postnasal drip, mucopurulent nasal discharge, general malaise, aching or pressure behind the eyes, or toothache-like pain. Fungi may be the causative agents, especially in patients with severe immunosuppression. Secondgeneration nonsedating antihistamines such as cetirizine, fexofenadine, and loratadine are not as effective as nasal steroids, but may give additional symptom relief. P: Plan Acute Sinusitis Combination therapy with antibiotics, decongestants, mucolytics, saline nasal spray, and topical nasal steroids may be effective. Epistaxis Epistaxis caused by coagulopathy or tumor is managed the same as for immunocompetent patients with these conditions. Patients with exacerbations of sinusitis should be treated as for acute sinusitis. Ritonavir may increase serum levels of cetirizine and may prolong its half-life; start with low dosage and monitor for adverse effects. Look for ribbed, whitish lesions on the lateral aspects of the tongue that cannot be scraped off (oral hairy leukoplakia). Conditions that arise in the oral cavity may be infectious, benign inflammatory, neoplastic, or degenerative processes. S: Subjective the patient may complain of white patches and red areas on the dorsal surface of the tongue and the palate, decreased taste sensation, white lesions along the lateral margins of the tongue, ulcers, nonhealing lesions at the corners of the mouth, sore gums, loose teeth, dysphagia, or odynophagia. It may appear as creamy white plaques on the tongue or buccal mucosa or as erythematous lesions on the dorsal surface of the tongue or the palate. The most common treatment strategy is empiric therapy with topical or systemic antifungal agents. Angular Cheilitis Angular cheilitis is also caused by Candida species, and it is characterized by fissuring at the corners of the mouth. Thorough examination of the mouth and throat with a tongue depressor and a good light is mandatory. Observe for white patches or plaques on the mucous membranes that can be partially removed by scraping with a tongue blade (candidiasis). Lesions appear most commonly on the hard palate but also occur on the gingival surfaces and elsewhere in the mouth. Oral Warts (Human Papillomavirus) Oral warts may appear as solitary or multiple nodules. The lesions may be smooth, raised masses resembling focal epithelial hyperplasia, or small papuliferous or cauliflower-like projections. Neisseria gonorrhoeae Pharyngitis Neisseria gonorrhoeae may be transmitted by orogenital exposure; the patient may have mild symptoms. However, treatment should be initiated to reduce the spread of the infection (see chapter Gonorrhea and Chlamydia). Gingivitis See chapter Necrotizing Ulcerative Periodontitis and Gingivitis for details. They appear as single or clustered vesicles and may extend onto adjacent skin of the lips and face to form a large herpetic lesion. The ulcers can appear anywhere in the oral cavity or pharynx and may be recurrent; they are extremely painful.

Grandparents Raising Grandchildren: According to the 2014 American Community Survey (U. While most grandparents state they gain great joy from raising their grandchildren, they also face greater financial, health, education, and housing challenges that often derail their retirement plans than do grandparents who do not have primary responsibility for raising their grandchildren. As individuals age, changes occur in these social networks, and the Convoy Model of Social Relations and Socioemotional Selectivity Theory address these changes (Wrzus, Hanel, Wagner, & Neyer, 2013). Both theories indicate that less close relationships will decrease as one ages, while close relationships will persist. The Convoy Model of Social Relations suggests that the social connections that people accumulate differ in levels of closeness and are held together by exchanges in social support (Antonucci, 2001; Kahn & Antonucci, 1980). According to the Convoy Model, relationships with a spouse and family members, people in the innermost circle of the convoy, should remain stable throughout the lifespan. In contrast, coworkers, neighbors, and acquaintances, people in the periphery of the convoy, should be less stable. These peripheral relationships may end due to changes in jobs, social roles, location, or other life events. These relationships are more vulnerable to changing situations than family relationships. Therefore, the frequency, type, and reciprocity of the social exchanges with peripheral relationships decrease with age. The Socioemotional Selectivity Theory focuses on changes in motivation for actively seeking social contact with others (Carstensen, 1993; Carstensen, Isaacowitz & Charles, 1999). This theory proposes that with increasing age, our motivational goals change based on how much time one has left to live. Rather than focusing on acquiring information from many diverse social relationships, as noted with adolescents and young adults, older adults focus on the emotional aspects of relationships. To optimize the experience of positive affect, older adults actively restrict their social life to prioritize time spent with emotionally close significant others. In line with this theory, older marriages are found to be characterized by enhanced positive and reduced negative interactions and older partners show more affectionate behavior during conflict discussions than do middle-aged partners (Carstensen, Gottman, & Levenson, 1995). Research showing that older adults have smaller networks compared to young adults, and tend to avoid negative interactions, also supports this theory. There is more support going from the older parent to the younger adult children than in the other direction (Fingerman & Birditt, 2011). In addition to providing for their own children, many elders are raising their grandchildren. They found that the older parents of adult children who provided emotional support, such as showing tenderness toward their parent, cheering the parent up when he or she was sad, tended to report greater life satisfaction. In contrast, older adults whose children provided informational support, such as providing advice to the parent, reported less life satisfaction. Daughters and adult children who were younger, tended to provide such support more than sons and adult children who were older. Friendships: Friendships are not formed in order to enhance status or careers, and may be based purely on a sense of connection or the enjoyment of being together. Being able to talk with friends and rely on others is very important during this stage of life. Bookwala, Marshall, and Manning (2014) found that the availability of a friend played a significant role in protecting the health from the impact of widowhood. Specifically, those who became widowed and had a friend as a confidante, reported significantly lower somatic depressive symptoms, better self-rated health, and fewer sick days in bed than those who reported not having a friend as a confidante. In contrast, having a family member as a confidante did not provide health protection for those recently widowed. Loneliness or Solitude: Loneliness is the discrepancy between the social contact a person has and the contacts a person wants (Brehm, Miller, Perlman, & Campbell, 2002). Women tend to experience loneliness due to social isolation; men from emotional isolation. Loneliness can be accompanied by a lack of self-worth, impatience, desperation, and depression. Novotney (2019) reviewed the research on loneliness and social isolation and found that loneliness was linked to a 40% 417 increase in a risk for dementia and a 30% increase in the risk of stroke or coronary heart disease. This was hypothesized to be due to a rise in stress hormones, depression, and anxiety, as well as the individual lacking encouragement from others to engage in healthy behaviors. In contrast, older adults who take part in social clubs and church groups have a lower risk of death. Opportunities to reside in mixed age housing and continuing to feel like a productive member of society have also been found to decrease feelings of social isolation, and thus loneliness. The Social Source Readjustment Rating Scale, commonly known as the Holmes-Rahe Stress Inventory, rates the death of a spouse as the most significant stressor (Holmes & Rahe, 1967). The loss of a spouse after many years of marriage may make an older adult feel adrift in life. They must remake their identity after years of seeing themselves as a husband or wife. Approximately, 1 in 3 women aged 65 and older are widowed, compared with about 1 in 10 men. Loneliness is the biggest challenge for those who have lost their spouse (Kowalski & Bondmass, 2008). Older adults who are more extroverted (McCrae & Costa, 1988) and have higher self-efficacy, (Carr, 2004b) often fare better. Positive support from adult children is also associated with fewer symptoms of depression and better adjustment in the months following widowhood (Ha, 2010). The context of the death is also an important factor in how people may react to the death of a spouse. The stress of caring for an ill spouse can result in a mixed blessing when the ill partner dies (Erber & Szchman, 2015). The death of a spouse who died after a lengthy illness may come as a relief for the surviving spouse, who may have had the pressure of providing care for someone who was increasingly less able to care for themselves. At the same time, this sense of relief may be intermingled with guilt for feeling relief at the passing of their spouse. The emotional issues of grief are complex and will be discussed in more detail in chapter 10. The widowhood mortality effect refers to the higher risk of death after the death of a spouse (Sullivan & Fenelon, 2014). Subramanian, Elwert, and Christakis (2008) found that widowhood increases the risk of dying from almost all causes. Men show a higher risk of mortality following the death of their spouse if they have higher health problems (Bennett, Hughes, & Smith, 2005). In addition, widowers have a higher risk of suicide than do widows (Ruckenhauser, Yazdani, & Ravaglia, 2007). However, adults age 65 and over are still less likely to divorce than middle-aged and young adults (Wu & Schimmele, 2007). Divorce poses a number of challenges for older adults, especially women, who are more likely to experience financial difficulties and are more likely to remain single than are older men (McDonald & Robb, 2004). However, in both America (Lin, 2008) and England (Glaser, Stuchbury, Tomassini, & Askham, 2008) studies have found that the adult children of divorced parents offer more support and care to their Source mothers than their fathers. While divorced, older men may be better off financially and are more likely to find another partner, they may receive less support from their adult children. Dating: Due to changing social norms and shifting cohort demographics, it has become more common for single older adults to be involved in dating and romantic relationships (Alterovitz & Mendelsohn, 2011). An analysis of widows and widowers ages 65 and older found that 18 months after the death of a spouse, 37% of men and 15% of women were interested in dating (Carr, 2004a).
If the infection is suspected erectile dysfunction what is it cheap kamagra effervescent 100 mg otc, treatment should be started while the diagnostic evaluation is being completed erectile dysfunction san francisco buy generic kamagra effervescent 100 mg. The asymptomatic carrier state is well docudiarrhea without fecal leukocytes or blood erectile dysfunction protocol download pdf buy kamagra effervescent 100mg online, abdominal pain erectile dysfunction rings generic kamagra effervescent 100 mg amex, nausea, and poor growth. When Blastocystis hominis this symptom complex, particularly Giardia intestinalis and Cryptosporidium parvum, should be investigated before assuming that B hominis is the cause of the signs and symptoms. Multiple forms have been described: vacuolar, which is observed most commonly in clinical specimens; granular; which is seen rarely in fresh stools; ameboid; and cystic. Because transmission is believed to be via the fecal-oral route, presence of the organism may be a marker for presence of other pathogens spread by fecal contamination. The parasite may be present in varying numbers, and infections may be reported as light to heavy. The most common clinical manifestation of blastomycosis in children is prolonged pulmonary disease, with fever, chest pain, and bacterial pneumonia, tuberculosis, sarcoidosis, or malignant neoplasm. Central nervous system infection is less common, and intrauterine or congenital infection is rare. Increased mortality rates for patients with pulmonary blastomycosis have been associated with advanced age, chronic obstructive pulmonary disease, cancer, and African American race. Blastomycosis is endemic in areas of the central southeastern states, and states that border the Great Lakes. The organism may be seen in sputum, tracheal aspirates, potassium hydroxide or a silver stain. Children with pneumonia who are unable to produce sputum may require bronchoalveolar lavage or open biopsy to establish the diagnosis. Bronchoalveolar lavage is high yield, even in patients with bone or skin manifestations. Organisms can be cultured on brain-heart infusion media and Sabouraud dextrose agar B dermatitidis. An assay that detects Blastomyces cross-reactivity occurs in patients with other endemic mycoses; clinical and epidemiologic considerations often aid with interpretation. Amphotericin B deoxycholate or lipid formulation is recommended for initial therapy of severe disease. Oral itraconazole is recommended for step-down therapy and for mild to moderate infection. Liposomal amphotericin B is recommended for central nervous system infection and may be folconazole (see Antifungal Drugs for Systemic Fungal Infections, p 905). Cough, rhinorrhea, wheezing, children with acute respiratory tract infections in various settings (eg, inpatient facilities, also been documented in children of similar age, complicating etiologic association with children with acute gastroenteritis; however, further studies are needed to better underyears of age. The frequent codetection of other viral pathogens of the respiratory tract in associacopathogen, it may be shed for long periods after primary infection, or it may reactivate been reported for up to 75 days after initial detection. Prolonged shedding of virus in respiratory tract secretions and in stool may occur after resolution of symptoms, particularly in immunecompromised hosts and therefore the duration of contact precautions should be extended in these situations. Appropriate hand hygiene, particularly when handling respiratory tract secretions or diapers of ill children, is recommended. Both are characterized by sudden onset of high fever, shaking chills, sweats, headache, muscle and joint pain, altered sensorium, nausea, and diarrhea. Findings and complications can differ between types of relapsing fever and include hepatosplenomegaly, jaundice, thrombocytopenia, iridocyclitis, cough with pleuritic pain, pneumonitis, meningitis, and myocarditis. Death occurs predominantly in people with underlying illnesses, infants, episode is followed by an afebrile period of several days to weeks, then by one relapse or of new borrelial antigens, and resolution of symptoms is associated with production of is severe and can result in spontaneous abortion, preterm birth, stillbirth, or neonatal infection. Worldwide, at least 14 Borrelia species cause tickborne (endemic) relapsing fever, including Borrelia hermsii, Borrelia turicatae, and Borrelia parkeri in North America. Borrelia recurrentis is the only species that causes louseborne (epidemic) relapsing fever and has no animal reservoir. Infection typically results from tick exposures in rodent-infested cabins in western mountainous residences and luxurious rental properties. B turicatae infections occur less frequently; most cases have been reported from Texas and often are associated with tick exposures in rodent-infested caves. A single human infection has been reported with B parkeri; the tick infected with this Borrelia species is associated with arid areas or grasslands in the western occurs when body lice (Pediculus humanus) become infected by feeding on humans with spicontaminate a bite wound or skin abraded by scratching. Infected body lice and ticks may remain alive and infectious for several years withtransmission from an infected mother to her infant does occur and can result in preterm birth, stillbirth, and neonatal death. Serum antibodies to Borrelia species can be detected by enzyme immunoassay and Western immunoblot analysis at some reference and commercial specialty laboratostandardized and are affected by antigenic variations among and within Borrelia species and strains. Serologic cross-reactions occur with other spirochetes, including Borrelia burgdorferi, Treponema pallidum, and Leptospira species. Tetracycline-based antimicrobial agents, including doxycycline, may cause permanent tooth discoloration for children younger than 8 years if used for with older tetracyclines, and in some studies, doxycycline was not associated with visible teeth staining in younger children (see Tetracyclines, p 873). For children younger than 8 years and for pregnant women, penicillin and erythromycin are the preferred drugs. Penicillin G procaine or intravenous penicillin G is recommended as initial therapy for people who are unable to take oral therapy, although low-dose penicillin G has been assoreaction accompanied by headache, myalgia, respiratory distress in some cases, and an associated with transient hypotension attributable to decreased effective circulating blood volume (especially in louseborne relapsing fever), patients should be hospitalized and pyretic agents alone. Single-dose treatment using a tetracycline, penicillin, erythromycin, or chloramphenicol is effective for curing louseborne relapsing fever. Dwellings infested with soft ticks should be rodent-proofed and treated professionally with chemical agents. When in a louse-infested environment, body lice can be controlled by bathing, washwestern states and is important for initiation of prompt investigation and institution of control measures. Physical pain and peripheral arthritis are reported more frequently in children than in adults. Anemia, leukopenia, thrombocytopenia or, less frequently, pancytopenia meningitis, endocarditis, and osteomyelitis and, less frequently, pneumonitis and aortic involvement. A detailed history including travel, exposure to animals and food habits, including ingestion of raw milk, should be obtained if brucellosis is considered. Chronic disease is less common among children than among adults, although the rate of relapse has been found to be similar. Brucellosis in pregnancy is associated with risk of spontaneous abortion, preterm delivery, miscarriage, and intrauterine infection with fetal death. The species that are known to infect humans are Brucella abortus, Brucella melitensis, Brucella suis, and rarely, Brucella canis. Brucella ceti, Brucella pinnipedialis, and Brucella inopinata, are potential human pathogens. Transmission occurs by inoculation through mucous membranes or cuts and abrasions in the skin, inhalation of contaminated aerosols, or ingestion of undercooked meat or unpasteurized dairy products. Clinicians should alert the laboratory if they anticipate Brucella might grow from microbiologic specimens so that appropriate laborabrucellosis are reported annually, and 3% to 10% of cases occur in people younger than tion of unpasteurized dairy products. Although human-to-human transmission is rare, in utero transmission has been reported, and infected mothers can transmit Brucella to their infants through breastfeeding. The incubation period varies from less than 1 week to several months, but most people become ill within 3 to 4 weeks of exposure. A variety of media will support growth of Brucella species, but the physician should contact laboratory personnel and greater reliability and can detect Brucella species within 5 to 7 days. In patients with a clinically compatible illness, serologic testing using the serum agglutination test can con- 1 American Academy of Pediatrics, Committee on Infectious Diseases, Committee on Nutrition. Although a single titer is not diagnostic, most patients with active infection in an of clinical disease onset. Increased concentrations of IgG agglutinins are found in acute infection, chronic infection, and relapse. When interpreting serum agglutination test results, the possibility of cross-reactions of Brucella antibodies with antibodies against other gramnegative bacteria, such as Yersinia enterocolitica serotype 09, Francisella tularensis, and Vibrio cholerae, IgG, IgA, and IgM anti-Brucella enzyme immunoassay should be used only for suspected cases with negative serum agglutination test results or for evaluation of patients with suspected chronic brucellosis, reinfection, or complicated cases. Polymerase chain reaction tests have been developed but are not available in most clinical laboratories. If a laboratory is not available to perform diagnostic testing for Brucella, physician should contact the state health department for assistance. Because monotherapy is associated with a high rate of relapse, combination therapy is recommended as standard treatment.
After cleansing the skin with an antiseptic agent erectile dysfunction mayo clinic cheap kamagra effervescent 100mg free shipping, place the towel drapes to square off the incision site (allow at least 5 cm [2 inches] of open skin around all sides of the proposed incision site) osbon erectile dysfunction pump buy kamagra effervescent 100 mg free shipping. Begin by placing the towel drape closest to you (1) to decrease the chance of contamination (see Figure A-4) impotence is the 100 mg kamagra effervescent. Holding one side of the drape erectile dysfunction treatment home buy generic kamagra effervescent 100mg line, allow the other side to touch the skin about 5 cm (2 inches) away from the proposed incision site. It can, however, be pulled away from the incision area but only at the same horizontal level. If an instrument stand is not available, a sterile/highlevel disinfected plastic or metal instrument tray can be placed on the drape covering the patient and used to hold instruments during the procedure. Note: As drapes wear out and new drapes are needed, try to buy replacement drapes that have a high thread count. If a drape is torn or cut during a procedure, it should be covered with a new drape. The antimicrobial agent should be started 60 minutes before surgical incision (120 minutes for vancomycin or fluoroquinolones). Although single-dose prophylaxis is usually sufficient, the duration of prophylaxis for all procedures should be less than 24 hours. Re-administration may also be warranted if prolonged or excessive bleeding occurs or if there are other factors that may shorten the half-life of the prophylactic agent. Re-administration may not be warranted in patients in whom the half-life of the agent may be prolonged. Level I evidence is from large, well-conducted, randomized controlled clinical trials. Ceftriaxone use should be limited to patients requiring antimicrobial treatment for acute cholecystitis or acute biliary tract infections that may not be determined prior to incision, not patients undergoing cholecystectomy for noninfected biliary conditions, including biliary colic or dyskinesia without infection. Fluoroquinolones are associated with an increased risk of tendonitis and tendon rupture in all ages; however, this risk would be expected to be quite small with single-dose antibiotic prophylaxis. Although the use of fluoroquinolones may be necessary for surgical antibiotic prophylaxis in some children, they are not drugs of first choice in the pediatric population due to an increased incidence of adverse events as compared with controls in some clinical trials. Factors that indicate a high risk of infectious complications in laparoscopic cholecystectomy include emergency procedures, diabetes, long procedure duration, intraoperative gallbladder rupture, age of > 70 years, conversion from laparoscopic to open cholecystectomy, American Society of Anesthesiologists classification of 3 or greater, episode of colic within 30 days before the procedure, re-intervention in less than 1 month for noninfectious complication, acute cholecystitis, bile spillage, jaundice, pregnancy, nonfunctioning gallbladder, immunosuppression, and insertion of prosthetic device. Because a number of these risk factors are not possible to determine before surgical intervention, it may be reasonable to give a single dose of antimicrobial prophylaxis to all patients undergoing laparoscopic cholecystectomy. The necessity of continuing topical antimicrobials postoperatively has not been established. For procedures in which pathogens other than staphylococci and streptococci are likely, an additional agent with activity against those pathogens could be considered. Although there are no data in support, patients undergoing brachiocephalic procedures involving vascular prostheses or patch implantation.

When doses differed between studies, expert opinion used the most-often recommended dose. When used as a single dose in combination with metronidazole for colorectal procedures. Although fluoroquinolones have been associated with an increased risk of tendinitis/tendon rupture in all ages, use of these agents for single-dose prophylaxis is generally safe.

Report on the Burden of Endemic Health Care-Associated Infection Worldwide: Clean Care Is Safer Care: A Review of the Literature. This is not considered significant except in pregnant women who are undergoing an invasive procedure involving the urinary tract, children with vesicoureteral reflux (backward flow of urine from the bladder to the upper urinary tract) or with accompanying blood culture with matching microorganism. Biofilm is an accumulated thin layer of bacteria and extracellular material that tightly adheres to surfaces. The presence of biofilm can increase the resistance of the bacteria to antimicrobial drugs and reduce the effectiveness of disinfectants and sterilization because products cannot penetrate the surface. Indwelling urinary catheter is inserted into the urinary bladder and left in place for continuous drainage of urine. Urinary catheters are indicated in health care to: l l l l Monitor urine output during certain types of surgery and with critically ill patients Manage urinary retention and obstruction Assist in healing of certain open wounds in incontinent (inability to control bladder) patients Improve comfort of patients at end of life, when requested Other indications for indwelling urinary catheters include any prolonged surgery, urological or genitourinary tract surgery, and infusion of large volumes of fluid or administration of diuretics. The longer a urinary catheter is left in the urethra and bladder, the greater is the risk of an infection (Lo et al. In many instances, urinary catheters are placed unnecessarily or remain in place for longer than needed. Catheter contamination can also occur from incorrect insertion or improper maintenance techniques. So, even when urinary catheters are used for essential patient care, they put patients at an increasing risk for infection each day by providing a route of entry for microorganisms into the sterile parts of the urinary tract. If the bladder empties completely during the voiding process, bacteria do not have the chance to grow and infect the bladder. The insertion of a catheter, however, bypasses these defenses, introduces microorganisms from the end of the perineum and urethra, provides a pathway for organisms to reach the bladder, and is a foreign body on which biofilm can form. Microorganisms may be lodged early and directly into the bladder during insertion or may later move up into the bladder from surrounding skin (capillary action). From the inside of the catheter (intraluminal)-microorganisms gain access to the bladder via movement along the inside (lumen) of the catheter. Contamination occurs when: l l A break in the closed drainage system occurs, resulting in contamination of the inside of the tubing or the catheter Urine flows in the opposite direction, toward the bladder (reflux), thereby introducing contamination from the collection bag to the bladder. Additionally, there is a category of multidrug-resistant Enterobacteriaceae, including E. Biofilm Microorganisms form biofilms (see Figure 2-2) on most devices that are inserted or introduced into the body, including urinary catheters and collection systems. Biofilms can be composed of gram-positive or gram-negative microorganisms and can also consist of a mixture of organisms. Biofilms allow bacteria to tightly adhere to surfaces; making it difficult to remove both the biofilm and bacteria using routine measures. For this reason, catheters should be inserted only for appropriate indications and kept in place only as long as needed. Placement of an indwelling catheter should be performed only when other methods of emptying the bladder do not work (see the section on alternative methods below). Loss of control (incontinence) or inability to void (retention) may be managed better by straight (in-and-out) catheterization several times a day rather than by use of an indwelling catheter. For example, if a catheter is being inserted because of urinary retention, ask the patient if she or he has voided (urinated) and the time of voiding, and measure the height of the bladder to ensure that there is retention of urine (assess urine volume with bladder ultrasound if available). Have male patients who have not been circumcised retract their foreskin and gently wash the head of the penis and foreskin with soap and water, if they are able to . Using cotton applicators or a gauze swab held with forceps, clean the urethral opening and surrounding area, including the labia minora, with an antiseptic solution. Apply antiseptic by moving from above, downward on one side, and then discarding the swab. Repeat on the other side, and lastly apply antiseptic at the center to clean the urethral opening (see Figure 2-5 A). Using cotton applicators or a gauze swab held with forceps, clean the head of the penis and urethral opening by applying antiseptic solution.
