Gynecological surgery is considered to be clear with possible contamination by gram-positive cocci from the skin, gram-negatives from the perineum or groins or polymicrobial biocenosis from vagina, depending on the surgical approach. Antibiotical prophylaxy enforces the natural mechanisms of immunity and helps to exclude present infection.
There were presented many studies comparing useful effect of prophylaxis in gynecological surgery. The benefits of antibiotical prophylaxy before IUD insertion, before the cervical surgery and before hysteroscopies were not verified.
On the other hand the prophylaxy of vaginal surgery including vaginal hysterectomy decreases the number of postoperative febrile complications. The positive influence of prophylaxis before the simple laparoscopy and laparoscopy without bowel injury or the opening of the vagina was not evidently verified.
In abdominal hysterectomy the antibiotical prophylaxy decreases the incidence of postoperative complications significantly. The administration of 2 g of cefazolin can be recommended.
In procedures taking more than 3 hours the repeated administration of cefazolin is suitable. New urogynecological procedures, using mesh implants, were not sufficiently evaluated as for postoperative infections and the posible antibiotical effect.
The presence of implant in possibly non sterile area should be considered as high risc of postoperative complications
