Novel coronavirus pneumonia yabweretsa anthu kumvetsetsa kwakukulu za kuwonongeka kwakukulu kwa matenda opatsirana pagulu la anthu kuyambira Disembala chaka chatha. Chinsinsi chothandizira kupewa ndi kupewa ndikuti muchite bwino popewa kulimbana ndi miliri ndikuyeretsa malo osamalira odwala.
Pakufufuza kwa labotale, ukadaulo wowunika mwamphamvu wa pulsed watsimikizika kuti umagwira bwino ntchito yoteteza tizilombo toyambitsa matenda komanso yolera yotseketsa. Pofuna kupitiliza kuphunzira za chilengedwe komanso kuthekera kwa ukadaulo wosalumikizanawu, katswiri wofufuza kafukufuku adachita kafukufuku wa miyezi inayi ku Queen's Hospital ku North London, UK.

Kafukufukuyu adachitika kuyambira Julayi 2014 mpaka Novembala 2014. Ma ward 40 odzipatula mchipatala adasankhidwa ngati zitsanzo za kafukufukuyu. Odwalawo atatulutsidwa mchipatala, adatsukidwa pamanja ndi mankhwala a hypochlorite, ndipo pomaliza pake amawotcherera ndi zida zamagetsi zamagetsi. Pambuyo pake, akatswiri adatenga zitsanzo za mabakiteriya a aerobic, ndikuwonetsa mbale ya agar yotsekemera kudera losasamalira odwala, ndikuyesa kupha tizilombo toyambitsa matenda Zomwe zotsatira za zida zamoyozo zitha kulembanso momwe ogwira ntchito kuchipatala amagwiritsira ntchito zida.

Njira yoyesera

Gulu lofufuzirali linapanga kafukufuku wofanizira kuti awonetse malo asanu olumikizirana pafupipafupi (mabedi am'bedi, matebulo am'manja, ma handrails, mipando ya chimbudzi ndi zida zam'manja zam'madzi) asanawonetse mankhwala ophera tizilombo, atachotsa tizilombo toyambitsa matenda komanso atachotsa mankhwala ophera tizilombo toyambitsa matenda a ultraviolet kuti awunikenso Zida zophera tizilombo toyambitsa matenda tating'onoting'ono topewa ma ultraviolet kuti muchepetse kuwonongeka kwa chilengedwe m'malo opatula odwala omwe atulutsidwa Kugonana.

Zitsanzo kusankha

Sankhani ma wadi (zipinda 6 pa chipinda) kuchokera kumagawo oyeserera azachipatala. Laborator imatsimikiziridwa ndi nkhokwe ya kachilombo kapewedwe kake ndikuthandizira kuti mugwiritse ntchito opewera ndikudziwongolera. Zomwe zasankhidwa mu labotale ndi izi:

(1) Iyenera kukhala chipinda chimodzi;

(2) Ayenera kukhala osachepera maola 48;

(3) Ayenera kuchotsedwa tsiku lomwelo zosonkhanitsira;

(4) Iyenera kugwiritsidwa ntchito ngati chipinda chodzipatula.

Njira yoyesera

Baseline microbiological sampuli adasonkhanitsidwa atatuluka, koma asanatsuke moyenera nthawi zonse. Malo asanu olumikizirana pafupipafupi adayesedwa koyambirira ndi mbale yolumikizana ndi trypsin soya agar (Oxford, Basingstoke, UK) yokhala ndi mamilimita 5 mm;

Oyeretsa zipatala amagwiritsa ntchito 1000 ppm (0.1%) mankhwala enaake a chlorine (activalum

Kuphatikiza; Ecolab, Cheshire, UK) poyeretsa pamayendedwe ndi sampuli yachiwiri;

Chipindacho chinali chowotcheredwa ndi pulse yotulutsa loboti. Mfundo zitatu zidasankhidwa kudera lililonse: mbali ziwiri za kama ndi bafa. Mfundo iliyonse idakulitsidwa ndi 5min. Pambuyo pochotsa tizilombo toyambitsa matenda, zitsanzo zinasonkhanitsidwa kuchokera pamalo asanu omwewo kuti amalize kuyesa komaliza.

Zitsanzo zomwe zasonkhanitsidwazo zimayikidwa pamalo osankhidwa kale kuti zisawonongeke kapena kusintha njira yoyeretsera. Pambuyo posonkhanitsa zitsanzo, trypsin soya agar mbale yolumikizirana idabwerera ku labotale, yotukuka m'mlengalenga pa 37 ° C kwa maola 48, yowerengeka ndikulemba kuchuluka kwa magulu opanga ma koloni (CFU).

Kusanthula deta

Chipinda chimodzi chidakanidwa chifukwa kunalibe chidziwitso chokhudza matenda azida zamagetsi, ndipo chitsanzocho chidachepetsedwa kukhala zipinda 39.

Pachiyambi, gawo lalikulu kwambiri (93%) la zipinda zoyipitsidwa lidawonedwa pamwamba pamiyala, yomwe idachepetsedwa kukhala 36% pambuyo poyeretsa pamanja ndi 7% itachotsa matenda opatsirana pogwiritsa ntchito loboti yotulutsa ma ultraviolet disinfection.

zotsatira zoyesera

Lobotilo litasilidwa ndi pulsed UV, kuipitsidwa kwa bakiteriya ku CFU kunatsika ndi 78.4%, 91% poyerekeza ndi gawo loyambirira la bioburden. CFU ya MDROs pa mbale ya msomali idachepetsedwa ndi chipika 5. Kufufuza ndi kufufuza, omwe amagwiritsa ntchito zida zawo amakhutira ndi kutonthozedwa kwa malonda.

mapeto

Zipangizo zowononga tizilombo toyambitsa matenda zambirimbiri zimagwiritsidwa ntchito m'malo onse azachipatala kuti zitsimikizire zaukhondo. Kupyolera mu kuyesaku, tapeza kuti:
1. Kuphatikiza koyeretsa kochita kupanga komanso kupha mankhwala ophera tizilombo sikunathetseretu kuwonongeka kwa tizilombo tachilengedwe.
2. Mutagwiritsa ntchito zida zamagetsi zotulutsa tizilombo toyambitsa matenda, kuwonongeka kwapansi kwa chipinda chodzipatulira kunachepetsedwa kwambiri.
