ABSTRACT

OBJECTIVE To explore the sterilizing effect of low-temperature vacuum formaldehyde.METHODS The test group used the own-produced 140 L low-temperature vacuum formaldehyde sterilizer for sterilization;and the control group used "Xinhua" hydrogen peroxide plasma sterilizer.Sterilization effect of the two groups was monitored by biological indicator.RESULTS After 50 sterilization procedures run in test group,the biological indicators the bacterial were all killed,the qualification rate of sterilization was 100%.But after 30 sterilization procedures run in control group,only 8 procedures were qualified,the qualification rate of sterilization was 26%.The sterilizing effect of the two groups was significantly different(P
