[Aseptic precautions in epidural catheterization for surgery].

We describe aseptic precautions in epidural catheterization for surgery. Every patient has to be checked for immunodeficiency, atopic dermatitis, preoperative use of antibiotics, and local infection of the epidural puncture site. Physicians who perform epidural catheterization should wear a mask and a cap and take off a wrist watch and rings on the fingers before an epidural kit is opened. Fingers and hands should be disinfected before wearing surgical gloves. The skin for epidural puncture site should be disinfected with 0.5% chlorhexidine in 80% ethanol. A micropore filter should be used when epidural catheterization is expected to remain over 24 hours.
