I don't know about guide lines but I think you should take a look at the epidemiology of your hospital/departiment to establish wheter or not be concerned about some particular resistance and so focus on something to prevent an ESBL/CRE/MRSA/VRE infection that could reasonably occure after that kind of intervention.
Using intravenous equipment you can incurr in various infections; of course if your patient is healty you have to concern a lil'bit less. If your patient is already immunologically compromised you have to pay more attention. The bacterial infection could be caused by: Acinetobacter, Pseudomonas, Klebsiella, Staphylococcus aureus, other enterobacteriaceae and Proteus/Serratia. All these m.o. love catheter and other medical equipments/surfaces. Disinfection, detergents, hands whashing and staff attention can prevent an infection more than a prophylaxis therapy, mostly if not a reasoned one.
If you can tell me something about your epidemiology I can try to help with the prophylaxis therapy.
Temporary trans-venous pacemakers don not require any require antibiotic prophylaxis. Your patient may require antibiotic prophylaxis for other reasons, in which case the choice should be according to that reason and not related to the pacemaker.
Antibiotic prophylaxis should be used if the patient has indication to permanent pacemaker implant because the presence of catheter for temporary pacing is a well known risk factor for late infections.
Antibiotic prophylaxis is a "must" in our clinic during throughout the hospitalization period with the presence of endocavitary temporary pacing electrode. However, there was a non-clear recommendations by IE guidelines or pacemaker guidelines. We thought that clinical experiences and approaches are the best ways to follow and administrate a prophylaxis in such patients (e.g. the hospital/CCU related infection rate).
