To prove the effectiveness of perioperative
antibiotics prophylaxis (PABP) in prevention of postoperative
infections after
vaginal hysterectomy the efficacy of rectale
Metronidazole application (5 times 500 mg; n = 192) was compared with that of Doxycyclin (2 times 200 mg intravenously; n = 116). The infectious morbidity after both prophylactic
antibiotic regimes was compared to that of an untreated group (n = 186). In spite of additionally colporrhapies the feverish standard morbidity without prophylaxis was 13.4%, after
Metronidazole application 13.5% and after Doxycyclin 2.6% (p less than 0.05). Simultaneously the rate of necessary
antibiotic treatment decreased significantly.
Pelvic infections complicated 16.7% of
vaginal hysterectomies having no prophylaxis, but only 4.3% after Doxycyclin medication (p less than 0.05). Postoperative
urinary tract infections (UTI)--mostly asymptomatic
bacteriuria--were not influenced by any PABP. Whereas UTI after bladder
catheter duration shorter than two days occurred in 26.0% (without PABP), 29.9% (
Metronidazole) respectively 18.2% (Doxycyclin; p greater than 0.05), the rates after a longer stay were 69.6%, 76.8% and 65.7%. It is concluded, that the febrile standard morbidity and
pelvic infections were reduced as well as the rate of necessary
antibiotics therapies by a prophylactic application of Doxycyclin, but not with
Metronidazole. The incidence of postoperative UTI was not reduced by prophylaxis.
