Abstract
To compare usual practices against published guidelines of Perioperative Antimicrobial Prophylaxis (AP), which is an established method to reduce the risk of postoperative infection in TJR.
We prospectively evaluated AP in 616 patients, who underwent TJR of the hip and the knee in an ongoing cohort study. Teicoplanin was administered once perioperatively (10mg/kg iv) in one group A (n=278), while in the other group B (n=338) AP was administered according to the usual practice (various antibiotic combinations, including hemisynthetic penicillins/penicillinase inhibitors, cephalosporins, aminoglycosides and quinolones for 2–10 days). An evaluation form and personal examination were used for data collection and monitoring. Patients were followed up for 2 years minimum.
The two groups did not statistically differ (p> 0.05) regarding overall postoperative infections. Superficial soft tissue infection developed in 9/616 pts. 1/278 in group A (0.4%) vs 8/338 in group B (2.4%) (p< 0.05). Deep SSI was rarely seen, 4/616 pts (0.6%). 2/278 in group A (0.7%) vs 2/338 in group B (0.6%) (p=NS). Mean duration of AP was significant higher in group B [6(IQR: 5–8.25)], p< 0.001 Mann-Whitney test. Only in group B, MRSA-MRCNS postoperative infections did appear. The duration (days) of glycopeptide antibiotic usage, therapeutic (group B) or prophylactic (group A), was comparable in both groups (p> 0.05).
Glycopeptide antibiotic prophylaxis for TJR leads to less postoperative infections compared to other antibiotic prophylaxis, but similar duration of overall glycopeptide usage (prophylactic and therapeutic) in both groups.
