Comparison of surgical hand scrub with Betadine and Decosept on bacterial colony count.
METHODS: 20 cases were selected of operating room scrub nurses according to various criteria. First, all subjects washed their hands for 1 min with soap. The bacterial pre-value was obtained by rubbing fingertips in Triptych Soy Broth (TSB) for 1 min. Then, in first stage, each subject scrubbed their hands with Betadine (povidone iodine 7.5%) for 3 min and dried with a sterile towel after rinse.
Bacterial postvalue (immediate effect) was obtained for one hand and the other hand was gloved for 2 hours. After the gloves were taken off, a second postvalue was obtained for sustained effect. After 1 week, for second stage, all subjects first washed their hands and the bacterial pre-value was obtained as for first stage. Then, each subject scrubbed with Decosept by using as many portions as necessary to keep hands wet for 3 min (10-12 ml). Bacterial post-values (immediate effect) were obtained for one hand and the other hand was gloved for 2 h. After the gloves were taken off, a second postvalue was obtained for sustained effect. Data were analysed by SPSS version 12. For comparison of BCC in each stage the paired t-test was used.
RESULTS: Comparisons of BCC frequency were different for immediate effect of Betadine and Decosept (38 & 25), and 2 h after scrub (72 & 40). The mean BCC reductions immediately after Betadine and Decosept scrub were of significant difference (PV=0.011). Also, the mean of BCC Incensement (sustained effect) were different (p = 0.011) 2 h after scrub. The mean of BCC immediate and 2 h after scrub with Betadine (first stage), showed Incensement (1.7). This Incensement after scrub with Decosept (second stage) was less than Betadine (1.15). So, the difference between first and second stages was significant (p = 0.001)
CONCLUSION: In general, comparison of BCC reduction in both stages (after scrub with Betadine and Decosept), not only in immediate but also sustained effect, showed the alcohol agent (Decosept) was more efficient in BCC reduction. We suggest more use of alcohol agents for hand surgical scrub instead of others.
