Treatment involves cleaning and debriding the infected skin and avoiding moisture. Therapy with diluted acetic acid can suppress P. The patient should be advised to avoid excessive immersion in hot water, even when wearing protective gloves.
After washing, the nails should be dried thoroughly, with the use of a hair dryer to keep the nail plate-nail bed space as dry as possible. Trimming of the nail, until the nail reattaches, should be repeated frequently for weeks. Treatment of the underlying fungal infection is indicated. Other treatments include: Clorox diluted two to three times a day to the space to suppress the growth of P.
Combination anti-Pseudomonal antibiotic therapy is necessary. Leukocyte transfusions or colony stimulating factors are often used. Mortality is high, even with aggressive antibiotic therapy and surgical resection.
Initial therapy should consist of parenteral anti-Pseudomonal therapy. Long-term anti-Pseudomonal therapy for example, oral ciprofloxacin may be necessary for cure. Topical agents are frequently used to prevent infection of burn wounds, including silver sulfadiazine and mafenide Sulfanylon.
Outbreaks of sulfadiazine-resistant organisms have occurred in burn units with its heavy usage. When topical agents are used prophylactically, there may be a delay in P. Mafemide has superior eschar penetration compared to silver sulfadiazine. Early and frequent debridement of necrotic tissue and excision of infected burn wounds is probably more important than topical therapy in preventing infection.
Bacteriophages have been tried see Adjunctive Therapy section. P atients with overt infection should be treated aggressively with combination IV antibiotics: an aminoglycoside and a beta-lactam. Antibiotic susceptibility testing is critical for antibiotic choice, since nosocomial strains may be multiply resistant.
Patients with significant burns have dramatic alterations in pharmacokinetics of most drugs. The risk in most patients may be under treatment rather than antibiotic toxicity The applicability of once daily dosing of aminoglycosides in burns patients is unknown, but is possibly advantageous. Individualized pharmacokinetic dosing with monitoring of aminoglycoside serum concentrations is recommended. Prompt removal of infected intravenous catheters or other hardware such as a ventriculoperitoneal shunt or ear piercing, should be performed, whenever possible.
In addition incision and drainage of abscesses, as well as debridement of soft tissue should be performed. Debridement of the bony involvement in a puncture wound of the foot is necessary for resolution of the osteochondritis infection.
Bacteriophages have been advocated as a potential topical application of treatment for post-burn P. A variety of phages are highly specific for P. A potential benefit of phage therapy is the lack of potential toxic effects, as well as diminished cost compared to systemic therapy. Limited clinical studies have been performed on this approach to therapy 1 , with a clear need for further exploration of this therapy Bacteremia due to P.
Risk factors for mortality include severe sepsis, pneumonia, and a delay in starting effective antimicrobial therapy. The choice and timing of antibiotic therapy is particularly crucial. As an example, in one study of episodes of P. The prognosis of P. In a patient with primary or secondary bacteremia, blood cultures should become negative. For urinary tract infection, urine culture should become negative. In a patient with P. The duration of therapy after an initial favorable clinical response is generally empiric.
Bacteremia and urinary tract infections require at least 10 days of therapy. Meningitis should be treated for 21 days, and endocarditis for at least 42 days. T he goal for most therapy is a curative course of antibiotics for P. Demonstration of sterilization of cultures, resolution of pain, soft tissue swelling, and erythema are all clinical features to follow in patients with P.
In cystic fibrosis, a course of systemic antibiotics will reduce the bacterial burden of chronic infection with P.
The endpoint for monitoring therapy of P. Persistent endotracheal colonization frequently occurs despite clinical response Currently, duration of therapy of days is suggested for P. However, if clinical criteria were used and ongoing colonization ignored , a duration of 8 days would appear reasonable Interest in a vaccine to prevent infection in susceptible hosts is tantalizing, especially in the care of patients with cystic fibrosis.
At present, no vaccine is commercially available, but development of vaccines against type II secretion system proteins, as well as LPS, is ongoing. In general P. The bacterium is a difficult organism to eradicate from areas that become contaminated, such as operating rooms, hospital rooms, clinics, and medical equipment. In a hospital room occupied by a patient with a known infection from P. Bars of soap can become contaminated with P. Nosocomial spread of bacteria is frequently by hands, including P.
Bacterial hand counts are higher with rings; long fingernails and artificial fingernails are associated with higher gram-negative bacterial hand contamination. Education of hospital and all medical personnel on proper hand hygiene is vital for successful infection control of P.
However, patient to patient transmission of multiply resistant P. In one investigation, three P. Molecular epidemiologic techniques i. A search for a common environmental source should be undertaken. Contact isolation precaution measures should be used as a mode of control of spread of such organisms if clonality is confirmed and no environmental source is found. Such an approach requires the identification of asymptomatic carriers of the organism and then accommodation of such individuals in single rooms or cohorting with other colonized patients.
Restriction of use of anti-Pseudomonal antibiotics should also be considered to reduce selective pressure leading to mutations contributing to multidrug resistance.
Cycling of antimicrobial agents used for empiric therapy has been attempted with some success in hospital intensive care units 6 , 94 , 95 , , , , , while more recent studies showed that cycling of antimicrobial agents did not control the emergence of gram-negative antimicrobial resistant organisms.
S team sterilization is the preferred method for preprocessing heat-stable medical devices. However manual cleaning to remove biological material is a necessary first step in reprocessing any medical device.
Disinfection and sterilization protocols do not work effectively on visibly soiled surfaces. The practice of rinsing equipment in tap water after preprocessing may contaminate a device.
