Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
* In the period 2003-2008 there were approximately 5,000 amputations per year in the UK.
* The Centre for Disease Control defines a Surgical Site Infection (SSI) as an infection within 30 days of an operation or up to one year if an implant is left in place and the infection is related to an operative procedure.
* Figures from the Surgical Site Infection Surveillance reported that the highest rate of surgical site infection was reported in association with lower limb amputation at 13.1%.
* There is a clear under-representation and the infection rate within our institution is approximately 25% which reflects the infection rate reported in a recent trial by Sadat et al (22.5%)
* Prevention of surgical site infections is of paramount importance to patients, healthcare providers and policy-makers, as they impact on morbidity and mortality and have significant time and cost implications.
* Currently there is NO CONSENSUS as to what the best practice is towards antibiotic administration in such patients. From a questionnaire-based audit we performed including vascular departments across the entire country, practice varies in both course duration (single dose → 5 days antibiotic course) as well as choice of antibiotics.
* The guideline at our institution suggests the 5-day course of antibiotic prophylaxis. The course duration varies depending on the clinical picture as well as microbiology results and recommendations.
* There are no randomised control trials that have investigated this aspect of patient care. We have set up one such trial and through it, we are looking to establish a standard practice which will hopefully be as beneficial as possible to the patient but also cost-effective for NHS.

Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
24 hour antibiotic course
24 hours of the stated antibiotics administered intravenously (Augmentin and metronidazole. Teicoplanin and or gentamicin will be used if penicillin allergic and state of renal function)
Co-amoxiclav
Augmentin 1.2g IV three times daily for 24 hours. If the patient is randomised to the 5-day duration antibiotic arm then Augmentin 625mg oral tablets three times daily are added to the 24 hour course for a further 4 days.
Iodine
Intra-operative skin preparation prior to incision to skin.
Metronidazole
500mg IV three times daily for 24 hours. If the patient is randomised to 5-day duration arm, then another 4 days of oral metronidazole at 400mg three times daily is added to the course
Chlorhexidine
Alcoholic Chlorhexidine skin pre-op preparation
Teicoplanin
Teicoplanin 400mg on induction. If penicillin allergic and on 5-day antibiotic arm then add clindamycin 300mg 4 times daily for further 4 days
5 day antibiotic Course
24 hours of IV antibiotics followed by 4 days of oral antibiotics (Augmentin and metronidazole. Teicoplanin and or gentamicin will be used if penicillin allergic and state of renal function. Clindamycin will be used as a an oral replacement for penicillin allergic patients)
Co-amoxiclav
Augmentin 1.2g IV three times daily for 24 hours. If the patient is randomised to the 5-day duration antibiotic arm then Augmentin 625mg oral tablets three times daily are added to the 24 hour course for a further 4 days.
Iodine
Intra-operative skin preparation prior to incision to skin.
