For surgery the most common organism you want to protect against is staphylococcus. The antibiotics most used for this purpose by the otolaryngologist that I work with are Keflex or Duricef after surgery (these are 1st generation cephalosporins/the class of antibiotic). Oftentimes, a patient will get some IV antibiotics as the surgery is beginning, sometimes just prior to.
In our office, we often use Augmentin which is Amoxicillin augmented by Clavulanate for sinus infections. The dosage for sinus infections is 875mg(of the Amoxicillin part, I forget the corresponding dose of the Cl. acid) every twelve hours for 10 days. I am no surgeon, but I think the choice of antibiotic and the dosage is odd. Wrong antibiotic, and if it were the right one it is the wrong dosage.
It depends, really, on what part of the body you were operated upon as well. Different bugs like to live different places.
[quote][url=http://www.ampath.co.za/AntiBiotGuide/chapter6.htm]Fundamental principles of Surgical Prophylaxis
o The antibiotic must be in the tissue before the bacteria are introduced i.e. antibiotic must be given intravenously shortly before surgery to ensure high blood / tissue levels. Prophylaxis failure may be due to antibiotics given too late or more often, given too early. The half-life of the particular antibiotic is therefore important.
o There is no data to support more than a single dose. Further doses generally constitute treatment. Note the waste of resources, the in-creased risk of complications and the fact that multiple doses are not associated with increased efficiency.
o The chosen antibiotics must be active against the most common ex-pected pathogens.
o Deviations from these guidelines may be warranted in certain situations, e.g. MRSA outbreak in an individual hospital.
o High risk patients, e.g. patients with jaundice or diabetics, or patients who undergo any procedures to insert prosthetic devices, generally warrant antibiotic prophylaxis.
N.B. There are no convincing statistical differences in efficacy between the 1st, 2nd or 3rd generation cephalosporins, therefore a 1st generation cephalosporin MUST be the preferred option[/url].[/quote]
Don’t know if this URL/reference is too “technical” for the layperson, but if you’re interested there’s a chart at the bottom that indicates the appropriate antibiotic for the organism, and which surgeries encounter which organisms, and it gives dosages and routes of medication administration, i.e., IV or pill or intrmuscular injection.
So, duuude, what kind of surgery did you have, duuude?
