Penggunaan UV untuk membersihkan permukaan barang/alat sudah biasa di lihat. Kali ini, saya ingin mengajak anda semua untuk memahami dengan lebih lanjut tentang kaedah sterilization alat-alat scope ENT menggunakan UV light 🙂

Abstract

Objective

To compare the effectiveness of disinfection protocols utilizing a ultraviolet (UV) Smart D60 light system with Impelux™ technology with a standard Cidex ortho-phthalaldehyde (OPA) disinfection protocol for cleaning flexible fiberoptic laryngoscopes (FFLs).

Methods

Two hundred FFLs were tested for bacterial contamination after routine use, and another 200 FFLs were tested after disinfection with one of four methods: enzymatic detergent plus Cidex OPA (standard), enzymatic detergent plus UV Smart D60, microfiber cloth plus UV Smart D60, and nonsterile wipe plus UV Smart D60. Pre- and post-disinfection microbial burden levels and positive culture rates were compared using Kruskal-Wallis ANOVA and Fisher’s two-sided exact, respectively.

Results

After routine use, approximately 56% (112/200) of FFLs were contaminated, with an average contamination level of 9,973.7 ± 70,136.3 CFU/mL. The standard reprocessing method showed no positive cultures. The enzymatic plus UV, microfiber plus UV, and nonsterile wipe plus UV methods yielded contamination rates of 4% (2/50), 6% (3/50), and 12% (6/50), respectively, with no significant differences among the treatment groups (p > 0.05). The pre-disinfection microbial burden levels decreased significantly after each disinfection technique (p < 0.001). The average microbial burden recovered after enzymatic plus UV, microfiber plus UV, and nonsterile wipe plus UV were 0.40 CFU/mL ± 2, 0.60 CFU/mL ± 2.4, and 12.2 CFU/mL ± 69.5, respectively, with no significant difference among the treatment groups (p > 0.05). Micrococcus species (53.8%) were most frequently isolated, and no high-concern organisms were recovered.

Conclusion

Disinfection protocols utilizing UV Smart D60 were as effective as the standard chemical disinfection protocol using Cidex OPA.

KOMEN SAYA:

Amat mudah…tapi sure mahal :P. UV sterilisation banyak kita jumpa untuk kegunaan water dispenser, even dekat escalator kan. Tapi UV Smart D60 ini memang terbukti berkesan untuk sterilise scopes ENT yang memang kita tahu, kene guna selalu dan kena cepat dibersihkan untuk digunakan untuk pesakit yang seterusnya…lagi-lagi di hospital kerajaan dimana pesakit boleh lebih dari 20 pesakit untuk di scope dalam satu hari. Wahhh, senang la kerja kami kalau Jabatan ENT HKL boleh beli mesin UV sterilisation isi:) Dalam 1 minit sudah dinyahkuman!
