Antimicrobial vs placebo prophylaxis in noncardiac thoracic surgery

Area of Science:

• Medicine
• Surgery
• Pharmacology

Background:

• Postoperative infections are a significant concern in noncardiac thoracic surgery.
• Prophylactic antibiotics are commonly used to prevent surgical site infections.
• The efficacy and safety of cephalosporins in this specific patient population require further investigation.

Purpose of the Study:

• To evaluate the efficacy of prophylactic cephalosporins in reducing postoperative infections.
• To assess the safety profile of prophylactic cephalosporins in patients undergoing noncardiac thoracic surgery.

Main Methods:

• Prospective, double-blind, placebo-controlled trial.
• 57 patients undergoing noncardiac thoracic surgery were enrolled.
• Patients received either cephalosporin therapy (28 patients) or a placebo (29 patients).

Main Results:

• The incidence of postoperative infections was similar between the cephalosporin group (17.8%) and the placebo group (17.2%).
• No significant differences were observed in WBC counts, fever, hospitalization duration, or hypersensitivity reactions.
• Adverse events such as drug fever, phlebitis, and abnormal renal function were more frequent in the cephalosporin group.

Conclusions:

• Prophylactic cephalosporins did not demonstrate efficacy in preventing postoperative infections in noncardiac thoracic surgery.
• Cephalosporin therapy was associated with an increased incidence of adverse events, including drug fever and renal dysfunction.
