Filter by:This is an observational study to evaluate the relative importance of the known risk factors for severe surgical site infections (SSIs) on the development of the more severe SSI cases, and to describe the demographic, clinical features, etiology and the management and outcome of patients suffering from severe SSIs in Spain.
The aim of the present study is to evaluate a new technique for prevention of sternal wound infection consisting of local application of collagen-gentamicin in addition to routine i.v. antibiotic prophylaxis. The technique has been evaluated in a previous randomised study. The aim of the present study is to evaluate the technique after it has been introduced in clinical practise to monitor the bacterial antibiotic susceptibility and to verify that the suggested reduction in sternal wound infection still exits.
Most cases of infection of clean-contaminated wounds (wounds without gross spillage of organisms from the gastrointestinal tract) are thought to originate from the skin. Therefore, it is conceivable that application of an optimal antiseptic agent can reduce the rate of surgical wound infections. This trial is to compare the impact of disinfecting the skin with Chloraprep (2%chlorhexidine and 70% isopropyl alcohol) vs. Betadine on the rates of infection of clean-contaminated surgical wounds. The study will also assess the occurrence of adverse effects on the skin from either antiseptic agent and the cost-savings associated with the use of Chloraprep vs Betadine.
The military is subject to traumatic wounds of various types and severity. Such wounds are predisposed to infection because they 1) tend to be extensive and deep, 2) may affect areas of normal carriage of potentially pathogenic bacteria in the gastrointestinal tract, upper respiratory tract, and the female genital tract, 3) typically produce tissue damage, 4) may introduce foreign bodies, 5) may interfere with local blood supply, 6) tend to produce ischemia, edema and hemorrhage, 7) may be complicated by fractures or burns and 8) may lead to shock and overwhelming of the body's systemic defenses. It will not always be possible in the military setting to cleanse and debride the wound promptly and effectively or to promptly provide surgery in the event of damage to vital structures. In the active military setting, the probability of wound infection following trauma is relatively high. In the absence of rapid identification of infecting flora and provision of information on antimicrobial susceptibility, clinicians must resort to empiric therapy rather than a tailored therapy. There is a tendency to use one of the top available agents that would likely be active against the vast majority of bacteria. This leads to increases in antimicrobial resistance, an important problem. The investigators hypothesize that the use of molecular biology techniques will provide identification of the microorganisms responsible for wound infection more rapidly and accurately. The investigators will evaluate real-time PCR (polymerase chain reaction) technique under this proposal. This procedure can be applied directly to material from the wound without need for first growing the organisms. It can be used to define the total flora of the wound within five hours. The investigators will first develop primers and probes that will detect the various bacteria anticipated in a given wound in a certain location. These primers and probes will be used in real-time PCR for rapid and accurate identification of the wound flora. The information obtained with real-time PCR is quantitative so that one may judge the relative importance of different isolates. The investigators will also use another molecular approach, 16S rRNA gene cloning, and conventional cultures; these will provide further information about the flora of various wounds. Definitive identification of anaerobes can be provided quickly and that, along with information on usual antimicrobial susceptibility patterns, can be life-saving or shorten the course of the infection considerably.
