Background:
Wound infections after saphenous vein harvest for coronary revascularization are common but they are infrequently examined. The aim of the present study was to investigate the risk factors for infection and the possible beneficial effects of saline lavage.
Methods:
From April 1996 to July 1996, 152 consecutive patients who underwent saphenous vein harvest for coronary artery bypass graft were recruited. Factors that may influence infection rates were analysed.
Results:
A total of 22 of the 125 (18%) patients included in the present study developed a wound infection. The length of the wound was the only variable found to have a statistically significant association with wound infection. In the analysis of patients with multiple leg wounds, the development of infection correlated with the absence of mechanical wash-out.
Conclusion:
The use of saline lavage may prevent wound infections by diluting the bacterial population prior to closure. The use of antiseptic or antibiotic lavage may offer an additional benefit.
