With intention of comparing two techniques of surgical hand antisepsis, a prospective study was accomplished with the male nurses team and surgeons of the surgical center of the Hospital Sarah/São Luís, in the period of June 2000 to June 2001. The techniques were classified in techniques "/\' and "B". Kindred of evaluating the effectiveness of the techniques as the elim ina tion of the transitory and part of the resident microbiota of the professiona ls' hands, it was picked samples before and after the antiseptic surgical scrub by impression of the professionals' hands in plates of Petri, sowed in agar blood and for sterile swab humidified with physiologic serum 0,9% in middle of culture th ioglicolato . The technique ''/\' was used by 77% (1O) of the professionals researched followed for 23% (3) of the others that used the technique "B". The differences between the used techniques were: uniformity and sequence of movements, repetition of the hand washing process and the accomplishment of the simple wash preceding the surgical wash and the time. Using the statistical test of Wilcoxon, considering p = 0,0015, 15% (02) of the professionals have presented bacterial growth (O1 used the technique ''/\' and the other used the technique "B") in the cultures accomplished after the surgical hand antisepsis procedure. The rnediurn time of surgical wash was 8 minut es. The applied statistical test in this study to compare the difference in effectiveness of the techniques didn't reveal significant result
