Bacteremia inotsanangurwa nekuvapo kwebhakitiriya muropa. Inogona kunge iri mhedzisiro yezviito zvakajairwa sekukwesha mazino, kurapwa mazino kana nzira dzekurapa, kana zvinogona kukonzerwa nehutachiona hwakadai sepneumonia kana weti tract infection. Kazhinji, bacteremia haifambidzani nechero zviratidzo, asi dzimwe nguva mabhakitiriya anoungana mune mamwe matukisi kana nhengo uye ane mhosva yezvirwere zvakakomba. Vanhu vari panjodzi huru yematambudziko kubva kubhakitiriya vanorapwa nemishonga inorwisa mabhakitiriya pamberi pemamwe marapirwo emazino uye nzira dzekurapa. Kana bacteremia ichifungidzirwa, iyo impirical administration yemishonga inorwisa mabhakitiriya inokurudzirwa. Kurapa kunozogadziriswa zvichienderana nemhedzisiro yetsika uye sensitivity bvunzo.

Bacteremia inotsanangurwa nekuvapo kwebhakitiriya muropa. Ropa rinenge riine sterile biological fluid. Kuonekwa kwebhakitiriya muropa ndiko saka a priori abnormal. Bacteremia inotaridzirwa netsika yeropa, kureva kurima kwekutenderera kweropa.

Avhareji yezera revarwere vane bacteremia ndeye 68 makore. Mazhinji mabhakitiriya ari mono-microbial (94%), kureva nekuda kwekuvapo kwemhando imwe chete yebhakitiriya. Vasara 6% vane polymicrobial. Majemusi makuru ari ega, pakaitika bacteremia, Escherichia coli (31%) uye Staphylococcus aureus (15%), uye 52% yemabhakitiriya anobva nosocomial mavambo (enterobacteria, Staphylococcus aureus).

Utachiona hunogona kukonzerwa nechimwe chinhu chisingakuvadzi sekukwesha mazino nesimba kana nechirwere chakakomba.

Non-pathological bacteremia

Zvinoenderana nekubuda kwenguva pfupi kwebhakitiriya muropa rinoonekwa semhedzisiro yezvinoitika muvanhu vane hutano:

• panguva yekugaya mabhakitiriya anogona kupinda muropa kubva muura;
• mushure mekutsvaira mazino kwakasimba, panguva iyo mabhakitiriya anogara mumazamu "anosundirwa" muropa;
• mushure memamwe marapirwo akadai sekubvisa zino kana kuyera, panguva iyo mabhakitiriya aripo mumazamu anogona kubviswa uye kupinda muropa;
• mushure mekugaya endoscopy;
• mushure mekuisa genitourinary catheter kana intravenous catheter. Kunyange zvazvo nzira dzeaseptic dzichishandiswa, nzira idzi dzinogona kutamisa mabhakitiriya muropa;
• mushure mekubaya majekiseni ekuvaraidza, nekuti tsono dzinoshandiswa dzinowanzosvibiswa nebhakitiriya, uye vashandisi havawanzo kuchenesa ganda ravo.

Pathological bacteremia

Zvinoenderana nehutachiona hwese hunoonekwa nekubuda kukuru kwebhakitiriya muropa kubva kune yekutanga kutapurirana, kunotevera mabayo, ronda kana hutachiona hweweti. Semuenzaniso, kuvhiya maronda ane utachiona, maabscesses kureva kuungana kwepus, uye bedsores, zvinogona kubvisa mabhakitiriya aripo panzvimbo ine utachiona uye kukonzera bhakitiriya. 

Zvichienderana nemaitiro epathophysiological, bacteremia inogona kuva:

• intermittent for thromboembolic uye endocarditic bacteremia: izvo zvinobuda zvinobva zvaita zvisingaite uye zvinodzokororwa;
• kuenderera mberi kwebhakitiriya re lymphatic origin senge brucellosis kana typhoid fever.

Kuva nejoint prosthesis kana prosthesis, kana kuva nechinetso nemavharuvhu emwoyo, kunowedzera ngozi yebhakitiriya inoramba iripo kana ngozi yokuti ndiyo inokonzera matambudziko. .

Kazhinji, bacteraemia inokonzerwa nezviitiko zvakajairika, sekurapa mazino, haawanzokonzeresa kutapukirwa, sezvo mabhakitiriya mashoma aripo uye aya anobviswa nekukurumidza nemuviri pachawo. , nekuda kwe phagocytes-mononuclear system (chiropa, spleen, bone marrow), kana nemamwe mazwi, nekuda kwesimba redu rekudzivirira zvirwere.

Aya mabhakitiriya anozogara kwenguva pfupi uye haaperekedzwe nechero zviratidzo. Aya mabhakitiriya, pasina mhedzisiro kune ruzhinji rwevanhu, anogona zvakadaro kupa njodzi muchiitiko chehosha yevalvular kana yakanyanya immunosuppression. Kana mabhakitiriya aripo kwenguva yakakwana uye muhuwandu hwakakwana, kunyanya kune varwere vane simba rekudzivirira muviri, bhakitiriya inogona kukonzera mamwe zvirwere uye dzimwe nguva inokonzera mhinduro yakaoma yakawanda kana sepsis.

Bacteremia inokonzerwa nemamwe mamiriro inogona kukonzera kupisa. Kana munhu ane bacteremia aine zviratidzo zvinotevera, anogona kunge ari kurwara nesepsis kana septic shock:

• kusingaperi fivha;
• kuwedzera kwemwoyo;
• chills;
• kuderera kweropa kana hypotension;
• zviratidzo zvomudumbu zvakadai sekurwadziwa mudumbu, kusvotwa, kurutsa uye manyoka;
• kukurumidza kufema kana tachypnée;
• kutadza kuziva, anogona kunge ari kurwara ne sepsis kana septic shock.

Septic shock inokura mu25 kusvika 40% yevarwere vane bacteremia yakakosha. Utachiona husina kubviswa ne immune system inogona kuungana munzvimbo dzakasiyana dzemuviri, zvichikonzera hutachiona mu:

• nyama inovhara uropi (meningitis);
• iyo yekunze envelopu yemoyo (pericarditis);
• masero akadzika mavharuvhu emwoyo (endocarditis);
• bone mwongo (osteomyelitis);
• majoini (infectious arthritis).
  

dziviriro

Vamwe vanhu vakaita sevanotevera vari panjodzi huru yematambudziko kubva kuBacteraemia:

• vanhu vane mavharuvhu emwoyo wakagadzirwa;
• vanhu vane majoini prostheses;
• vanhu vane abnormal heart valves.

Izvi zvinowanzorapwa nemishonga inorwisa mabhakitiriya isati yaitwa chero ipi zvayo inogona kukonzera bhakitiriya sekumwe kuchengetwa kwemazino, nzira dzekurapa, kurapwa kwekuvhiya kwemaronda ane hutachiona nezvimwe. Mishonga inorwisa mabhakitiriya inogona nokudaro kudzivirira bacteremia uye nekudaro kukura kwehutachiona uye sepsis.

mabatiro

Muchiitiko chekufungira bhakteria, zvinokurudzirwa kushandisa mishonga inorwisa mabhakitiriya empirically, kureva kuti pasina kumirira kuzivikanwa kweiyo microorganism iri mubvunzo, mushure mekutora sampuli dzetsika dzenzvimbo dzakabva. zvinogona. Kumwe kurapa kunosanganisira:

• gadzirisa mishonga inorwisa mabhakitiriya zvichienderana nemigumisiro yetsika uye susceptibility testing;
• bvisa maabscesses nekuvhiya, kana paine abscess;
• bvisa midziyo yese yemukati ingangove inofungidzirwa sosi yebhakitiriya.
