A single dose of ceftriaxone is as effective as a 48-hour antibiotic regimen for cardiac surgery prophylaxis. This approach is more cost-efficient and reduces intravenous administrations.

Area of Science:

  • Infectious Diseases
  • Surgical Prophylaxis
  • Pharmacoeconomics

Background:

  • Antibiotic prophylaxis is crucial in preventing surgical site infections following cardiac operations.
  • Traditional prophylaxis regimens can involve prolonged administration and higher costs.

Purpose of the Study:

  • To compare the efficacy and cost-effectiveness of single-dose ceftriaxone versus a 48-hour flucloxacillin/gentamicin regimen for antibiotic prophylaxis in adult cardiac surgery.
  • To evaluate infection rates, administration burden, and toxicity profiles of the two regimens.

Main Methods:

  • A clinical trial involving 1,031 adult patients undergoing cardiac operations.
  • Comparison of infection incidence between patients receiving single-dose ceftriaxone and those receiving a 48-hour flucloxacillin/gentamicin regimen.

Main Results:

  • No significant difference in overall major infection rates (5.8% vs. 5.6%, p=0.89).
  • Single-dose ceftriaxone significantly reduced intravenous administrations (864 vs. 9,570 doses) and costs (A$17,248 vs. A$78,510).
  • Gentamicin-containing regimen showed greater renal impairment, though overall toxicity was low.

Conclusions:

  • Single-dose ceftriaxone is a cost-efficient and effective prophylactic strategy for adult cardiac surgery.
  • Short-term antibiotic administration is optimal for prophylaxis in cardiac procedures.
