I-Septic Cavernous Sinus Thrombosis: "Ingozi Unxantathu Wobuso" Amathumba, I-Sphenoid/Ethmoid Sinusitis, I-Early Sixth-Nerve Palsy, kanye ne-Bilateral Proptosis¶

I-Septic cavernous sinus thrombosis (CST) iyisimo esiphuthumayo esiyingozi, esisongela ukuphila kwe-neurovascular lapho ihlule legazi elithelelekile (septic thrombus) lakheka ngaphakathi kwezono ze-cavernous, i-trabeculated, i-venous chamber egcwele igazi ehlezi ngqo phansi kobuchopho nhlangothi zombili ze-pituitary gland (sella turcica) kanye ne-sphenoid sinus. Ngoba* umthambo wobuso (angular vein)** kanye nemithambo yamehlo esezingeni eliphezulu nephansi edonsa phakathi kobuso bomuntu nezisekelo zamehlo 100% ayinama-valve (iqukethe ama-valve e-venous ayi-zero), amagciwane aphuma ethumba elimpintshiwe noma iqhubu ngaphakathi "Kunxantathu Wengozi Yobuso" (kusuka emakhoneni omlomo noma i-noid bridge) i-ethmoid sinus infection**,orbital cellulitis, noma ithumba lezinyo elingenhla lingageleza lihlehle (retrograde) iqonde ogebhezini. Uma othile osanda kuthola isifo se-sinus, ithumba emakhaleni, noma i-cellulitis ebusweni eba ikhanda elibuhlungu elibuhlungu ngemuva kwamehlo, imfiva, ukuvuvukala noma ukuqhuma kweso (proptosis), ukungakwazi ukubhekisa iso ngaphandle endlebeni (sixth cranial nerve palsy kubangela ukubona kabili), ijwabu leso eligobile (ptosis), noma ukuvuvukala kweso okweqa kusuka kwelinye iso kuya KWAMABILI emehlweni phakathi kwamahora angu-24 kuya kwangu-48, shayela indawo yangakini izinombolo eziphuthumayo (911 e-United States naseCanada, 112 kwi-European Union, 999 e-United Kingdom, noma 000 e-Australia) ngokushesha. Ngenkathi ulinde ezokuthutha zasesibhedlela, buyekeza iziqondiso esihambisana nazo ku i-orbital cellulitis kanye nokutheleleka kukanxantathu oyingozi ebusweni, i-acute coalescent mastoiditis kanye ne-sigmoid sinus thrombosis, futhi i-meningitis kanye ne-meningococcal septicemia triage.

Kungani i-septic cavernous sinus thrombosis ibonakala ngokukhethekile eceleni kombhede uma wazi ukuthi yini okufanele uyihlole? Ngoba ngokungafani nanoma yisiphi esinye isakhiwo emzimbeni womuntu, icavernous sinus ine-artery (the internal carotid artery) kanye ne-cranial nerve (Cranial Nerve VI, the abducens nerve) egijima ngokuqondile phakathi nendawo yayo yegazi, kuyilapho ezinye izinzwa ezine ze-cranial (CN III, CN IV, CN \(\text{V}_1\), kanye ne-CN \(\text{V}_2\)) igijima ishumekwe odongeni lwayo olungaphandle olusemaceleni. Ukwengeza, izono ze-cavernous kwesokunxele nesokudla zixhunywe phakathi komugqa ophakathi nge-intercavernous sinuses. Ngenxa yalokho, i-CST ye-septic ikhiqiza isiginesha yomtholampilo yezinyathelo ezimbili** yakudala, engaqondakali: 1. Okokuqala (Early Hours): Isolated Ipsilateral Lateral Gaze Palsy (Cranial Nerve VI Palsy: ukungakwazi ukuguqula iso elithintekile libheke ngaphandle ngasethempelini) okuhambisana nekhanda elijulile le-retro-orbital kanye nesiphongo/ukuba ndikindiki kwekhone (CN V1). 2. Okwesibili (Within 24 to 48 Hours: Uphawu Lwe-Pathognomonic): Ukusabalala kokuvuvukala kwejwabu leso, ibhaluni ye-conjunctival (chemosis), iso eliqhumile (proptosis), nokunyakaza kwamehlo okuqandisiwe (ophthalmoplegia) kuya kokuphambene (contralateral) iso, ukuguqula inkinga yeso elihlangothini olulodwa ibe inhlekelele izinhlangothi ezimbili.

Yenza lokhu manje¶

1. Yenza Ukuhlolwa Kwamehlo Okulandelela Iminwe Yemizuzwana engama-30 (okuvundlile)Testing Cranial Nerve VI) kanye nethi "Both-Eyes Symmetry Check" ngokushesha. Cela isiguli ukuthi sibambe ikhanda singanyakazi futhi silandele umunwe wakho kancane siye kwesokunxele esikude nakwesokudla:
2. Ifulegi Elibomvu Lakuqala (CN VI Abducens Palsy): Ingabe iso elilodwa liyehluleka ukujika libheke endlebeni (abduction deficit), okubangela ukuthi isiguli sibone izithombe ezimbili ezibheke eceleni (i-diplopia evundlile) lapho sibheke ngakulolo hlangothi?
3. Ifulegi elibomvu elithuthukisiwe (CN III & IV + Bilateral Spread): Ingabe ijwabu leso liyashona (ptosis), ingabe umfundi unwetshiwe futhi uyavilapha, ingabe iso liqandiswe endaweni emaphakathi (i-ophthalmoplegia yangaphandle ephelele), noma ingabe ukukhukhumala/ubomvu kuqalile ukuvela kwesibili (eliphambene) iso?
4. Shayela 911 / 112 / 999 ngokushesha uma noma yimaphi amathumba ebusweni, i-sinusitis, noma ububomvu bejwabu leso kuhambisana YIYIPHI I-Cavernous Sinus noma I-Orbital Red Flag:
5. Ukubona kabili (diplopia), ukunyakaza kwamehlo okubuhlungu noma okunomkhawulo, noma ijwabu leso eligobile.
6. I-Proptosis (inhlamvu yeso equmbile) noma i-chemosis (ukuvuvukala oku-translucent okufana nejeli kwe-conjunctiva emhlophe ephuma phezu kwejwabu leso elingezansi).
7. Ukulahlekelwa ukubona, ukufiphala, noma ukulahlekelwa ukugcwala kombala obomvu (afferent pupillary defect).
8. Ukuba ndikindiki, ukuluma, noma ubuhlungu obushisayo esiphongweni, ijwabu leso eliphezulu, ikhala, noma isihlathi esingenhla (Cranial Nerve V1 / V2 trigeminal sensory deficit).
9. Ikhanda elibuhlungu elibuhlungu le-retro-orbital noma langaphambili, intamo eqinile, i-photophobia, ukudideka, ukukhathala, noma imfiva ye-"picket-fence" ehlabayo kakhulu (39.5°C+ / 103°F+) ngokuqhaqhazela amakhaza (rigors).
10. UNGALOKOTHI ukhame, uqhamuke, ujube, noma ulawule induna, iqhubu (thumba), noma uboya bekhala obungene ngaphakathi "Kunxantathu Oyingozi Yobuso." Unxantathu Oyingozi ugijima usuka ebhulohweni lekhala (glabella) phansi emakhoneni angakwesokunxele nangakwesokudla odebe olungaphezulu (oral commissures), okuhlanganisa umpheme wamakhala (ngaphakathi emakhaleni) kanye nephiltrum. Ukukhama i-Staphylococcus aureus enegciwane elibilisa kule zoni kuphoqa amagciwane kanye ne-micro-thrombi ethelelekile emuva ngemithambo ye-angular kanye ne-ophthalmic engenamaviyo iqonde ngasesinqeni se-cavernous.
11. Uma ithumba noma i-crusted nasal vestibule infection (nasal furunculosis) ikhona ngaphakathi kwe-Danger Triangle ngaphandle kwezimpawu zemizwa: faka i-compress emanzi ehlanzekile, efudumele ngobumnene ukuze 15 minutes 3 to 4 times daily ngaphandle kokucindezelwa noma ukukukhama, geza izandla ngensipho, futhi ubone udokotela ngokushesha ukuze uthole i-topical Intranasal Mupirocin (2%) amafutha okugcoba kanye nemithi elwa ne-staphylococcal yomlomo (cephalexin, dicloxacillin, doxycycline, or TMP-SMX).
12. Gcina isiguli siya eMnyangweni Wezimo Eziphuthumayo esibhedlela ngokuqinile NPO (akukho lutho ngomlomo: ukudla okuyiziro, amanzi anguziro). Iziguli ezine-septic cavernous sinus thrombosis ebangelwa i-acute sphenoid/ethmoid sinusitis, ithumba lamazinyo, noma ithumba elingaphansi kwe-orbital subperiosteal ngokuvamile lidinga *i-endoscopic endoscopic sphenoidotomy / ethmoidectomy ephuthumayo phakathi kwamahora okuhlinzwa okujwayelekile kokuhlinzwa.
13. Phakamisa ikhanda lombhede noma uhlaka ukuze 30 to 45 degrees ngesikhathi sokuthutha ukunciphisa ukuminyana kwe-venous kwe-intracranial kanye ne-intra-orbital ngenkathi igcina intamo isendaweni engathathi hlangothi, engagobile ukuze ukuphuma kwe-venous ye-jugular yangaphakathi kungavinjelwa.

Ingxenye 1: I-Anatomy "Yonxantathu Wengozi" kanye Nokwakhiwa Kwangaphakathi Kwe-Cavernous Sinus¶

Ukuqonda amapulani amabili e-anatomical, (1) umgwaqo ongu- valveless veous onguthelawayeka osuka ekhaleni uya esisekelweni sogebhezi kanye (2) ne-imephu enqamula ingxenye yezinzwa ze-cranial ngaphakathi kwe-cavernous sinus, ichaza zonke izimpawu eziba khona isiguli.

1. Imigwaqo Emi-3 Ye-Venous Engena Ku-Cavernous Sinus¶

Kungani i-cavernous sinus iyimpambano yemithambo emaphakathi yobuso obungaphezulu, amehlo, izindlebe, nengqondo? 1. Indlela Yangaphambili (Kusuka "Kunxantathu Wengozi Yobuso" Nesokhethi Yeso): - Dweba unxantathu emagumbini ** omlomo (labial commissures)** kuze kube ibhuloho lekhala (nasion/glabella). - Igazi le-venous eliphuma emlonyeni ongaphezulu, i-philtrum, i-nasal tip, kanye ne-nasal vestibule lingena emthanjeni wobuso -> umthambo we-angular ** (ekhoneni elingaphakathi leso), ohlanjululwa ngokuqondile nge-superior ophthalmic vein (SOV)* kanye ne-*inferior ophthalmic vein (IOV)**. - Ngenxa yokuthi le mithambo inama-zero valves, i-septic thrombophlebitis isakazeka ngokuqondile emuva ngokufahla okungaphezulu kwe-orbital ukuya ngaphambili kwe-cavernous sinus. 2. Indlela Ephakathi (Kusuka Kuzono Ze-Sphenoid Ne-Ethmoid: Imbangela Yesimanje # 1): - Esikhathini samanje semithi elwa namagciwane, i-acute sphenoid sinusitis kanye ne-posterior ethmoid sinusitis i-akhawunti ethi over 50 to 60 percent yazo zonke izimo ze-septic cavernous sinus thrombosis. - Izono ze-cavernous zesokunxele nesokudla zihlala zinamekwe ngokuqondile ngokumelene nezindonga zamathambo asemaceleni ezacile ze-sphenoid sinus (often less than 0.5 mm thick, with natural bony dehiscent gaps). Ukutheleleka kuwela ngqo ethanjeni elincanyana noma nge-valve encane i-diploic kanye nemithambo ye-essary. 3. Izindlela Eziphansi Nezangemuva (Kusuka Kwamazinyo Angenhla Nethambo Lemastoid): - Amathumba amazinyo omhlathi ongenhla (maxillary molars/incisors) hambela phezulu nge-pterygoid venous plexus nge-foramen ovale/lacerum uye phansi kwe-cavernous sinus, kuyilapho izifo zendlebe/mastoid (petrous apicitis / Gradenigo syndrome) zihamba phambili ezinombolweni ze-petrosal eziphakeme nezingaphansi.

Ngemuva kokudweba amasethi amabili wamasiko egazi e-aerobic kanye ne-anaerobic (alungile ku 70% we-acute septic CST cases), odokotela banikeza ngokushesha i-central-nervous-system-penetrating (i-meningeal-dose) ama-antibiotics emithanjeni: - Ingxenye 1 (I-Anti-MRSA / I-Anti-Staphylococcal Coverage): I-Vancomycin Emithanjeni (15 to 20 mg/kg IV every 8 to 12 hours, nge 25-30 mg/kg ukulayisha umthamo kuhloswe umkhombe 15-20 mcg/mL) NOMA Intravenous Linezolid (600 mg IV every 12 hours) (okufeza i-CSF ephakeme nokugxila kwezicubu zobuchopho uma i-vancomycin iphikiswa). (Uma amasiko kamuva eqinisekisa ukuthi i-methicillin-susceptible S. aureus [MSSA], emincane ukuya kumthamo ophezulu IV Nafcillin noma Oxacillin 2 g IV every 4 hours). - Ingxenye 2 (I-Cephalosporin Yesizukulwane Sesithathu noma Sesine se-Pneumococcus & Gram-Negatives): Intravenous Ceftriaxone (2 grams IV every 12 hours: i-meningeal dosing double-dosing) NOMA I-Cefepime ye-Intravenous (2 grams IV every 8 hours) (uma i-Pseudomonas noma ukuchayeka ekunakekelweni kwezempilo kusolwa). - Ingxenye 3 (I-Anaerobic Brain/Sinus Ukungena): Intravenous Metronidazole (500 mg IV every 6 to 8 hours). (Okunye, I-Meropenem Emithanjeni 2 grams IV every 8 hours + I-Vancomycin ihlanganisa zonke izigaba ezintathu zamagciwane ohlelweni lwezidakamizwa ezimbili). - Ubude besikhathi sokwelashwa kwe-IV: Ubuncane obungu-3 ukuya kumaviki angu-4 bemithi elwa namagciwane efakwa emthanjeni (inwebelwe ku-6 kuya kumaviki angu-8 uma ihambisana ne-frontal/sphenoid bone osteomyelitis noma i-intracranial brain/epidural abscess).

2. I-High-Resolution Neuroimaging (Contrast Brain MRI with MR Venography + Thin-Slice Sinus/Orbit CT)¶

Izikena ze-CT zekhanda ezingahlukani ezingenalutho zigeja kufika ku 30% to 50% ye-cavernous sinus thromboses yokuqala. - I-MRI Yengqondo Ethuthukisiwe Ethuthukisiwe ne-MR Venography (MRV) yilona izinga legolide lokuxilonga elibucayi kakhulu: libona ngeso lengqondo ukunwebeka okuqondile ukunwebeka kanye nokugoqa okungemuva kwezindonga ze-cavernous sinus, isignali yokugeleza kwe-venous engekho / amaphutha okugcwalisa ngaphakathi kwe-cavernous sinus, ukunwetshwa kanye ne-thrombosis yomthambo wamehlo ophakeme (i-ophthalmic vein)SOV), ukuthuthukiswa kwe-dural, kanye nokuncipha komthambo we-carotid wangaphakathi we-intracavernous. - Ucezu Oluncane Olunokulungiswa Okuphezulu (1 mm) Qhathanisa i-CT ye-Orbits kanye ne-Paranasal Sinuses (CT Venography / CTV): Kwenziwe ngokushesha eduze kwe-MRI ukuze kumephu ukuguguleka kwamathambo sphenoid kanye nezono ze-ethmoid kanye nokuqondisa ukugeleza kwamanzi okuhlinzwa kwe-endoscopic.

3. I-Anticoagulation (Intravenous Unfractionated Heparin noma LMWH)¶

Ingabe kufanele unikeze izinto ezinciphisa igazi (anticoagulation) esigulini esinehlule elithelelekile ku-cavernous sinus? - Imvumelwano Yamanje Yomtholampilo (AHA/ASA Cerebral Venous Thrombosis Guidelines Nokubuyekezwa kwe-Cochrane): Once neuroimaging (CT/MRI) akuhlanganisi ukopha okubalulekile emkhathini noma i-carotid mycotic aneurysm ephukile, i-adjunctive anticoagulation yakuqala nge-Intravenous Unfractionated Heparin (UFH: ikhethwa ekuqaleni ngoba ingacishwa futhi ibuyiselwe emuva nge-protamine phakathi nemizuzu ngaphambi kokuhlinzwa kwe-sinus) noma i-Low-Molecular-Weight Heparin (Enoxaparin 1 mg/kg SC every 12 hours) imisa ukusakazeka kwehlule kuyo yonke i- intercavernous sinus iye kwelinye iso futhi ithuthukise ukungena kwemithi elwa namagciwane ku-thrombus, kunciphisa kakhulu ukufa (from -30% down to < 10-15%) kanye nobumpumputhe benzwa ye-cranial unomphela. I-Anticoagulation ivamise ukuqhubeka amaviki angu-6 kuya ezinyangeni ezi-3 kuze kube yilapho i-venous ikhishwa kabusha.

4. Ukulawula Umthombo Wokuhlinza Okuphuthumayo (Endoscopic Sphenoidotomy / Ethmoidectomy noma i-Abscess Drainage)¶

Ama-antibiotics kanye ne-heparin awakwazi ukuvala amagciwane e-sphenoid sinus evaliwe egcwele ubomvu obucindezelekile. Uma i-CT imaging ikhomba i-acute sphenoid/ethmoid sinusitis, ithumba le-orbital subperiosteal, noma ithumba lamazinyo/ebusweni, Otolaryngologist (ENT surgeon) noma Udokotela Ohlinza Ngomlomo & Maxillofacial uthatha isiguli ngokushesha asise egunjini lokuhlinza I-Functional EndoscolFESS: i-endoscopic endoscopic sphenoidotomy ne-ethmoidectomy) noma ukuphuma kwethumba. (Qaphela: Odokotela abahlinzayo bakhipha i-sinus eyinhloko noma umthombo wobuso; ABASIki ngokuqondile egunjini le-cavernous sinus uqobo).

Izinombolo eziphuthumayo zesifunda kanye ne-neurovascular triage¶

I-septic cavernous sinus thrombosis esolwayo idinga ukuthuthwa kwe-ambulensi ngokushesha ku- Umnyango Wezimo Eziphuthumayo Ophelele WeStroke/Tertiary Hospital ofakwe amahora angu-24 we-MRI/MRV, Neurosurgery, Neurology, Ophthalmology, and Otolaryngology (ENT) Ukuhlinzwa:

Imibuzo evame ukubuzwa¶

Iyini "Unxantathu Wengozi Yobuso," futhi kungani ukukhama induna lapho kungabangela ihlule legazi lobuchopho?¶

"I-Danger Triangle of the Face" indawo engunxantathu egijima isuka ebhulohweni lekhala lakho yehle iye kwesokunxele nesokudla emakhoneni omlomo wakho, okuhlanganisa ikhala lakho, amakhala, nodebe olungaphezulu. Ngokungafani nemithambo esemzimbeni wakho wonke enama-valve asendleleni eyodwa yokugcina igazi ligeleza libheke enhliziyweni yakho kuphela, umthambo wobuso (i-angular vein) kanye nemithambo yamehlo ephakeme nengaphansi ezungeze amehlo akho inamavalve ayiziro. Uma ukhama noma uqhumisa ithumba elijulile noma induna (evame ukungenwa yi-Staphylococcus aureus) emakhaleni noma udebe olungaphezulu, ukuvuvukala okuzungezile kuvimbela ukugeleza okujwayelekile okuya phansi, futhi umfutho ocindezelayo uphusha igazi elinegciwane kanye namagciwane lihlehle ngemithambo yamehlo liqonde ngqo ku-cavernous sinus phansi kobuchopho.

Kungani ukungakwazi ukuphendulela iso elilodwa ngaphandle ("i-sixth-nerve palsy") kuwuphawu lokuqala oluyisixwayiso lwe-cavernous sinus thrombosis?¶

Izinzwa ezinhlanu ze-cranial zidlula ku-cavernous sinus zisendleleni eya esweni nasebusweni: I-Cranial Nerves III, IV, V1, ne-V2 ifakwe ngokuphephile ngaphakathi kodonga lwangaphandle oluqinile lwe-sinus, kuyilapho i-Cranial Nerve VI (umsipha we-abducens, olawula umsipha ophendulela iso lakho libheke echibini lendlebe elingaphakathi kwesokudla elintantayo eliseduze) umthambo we-carotid. Lapho amabhaktheriya namahlule egazi kuqala kungena ku-cavernous sinus, i-Cranial Nerve VI iyinzwa yokuqala egcwele ubovu nomfutho. Isiguli esinesifo se-sinus noma ithumba ebusweni futhi ngokuzumayo sibe nombono ovundlile ovundlile ngoba iso elilodwa alikwazi ukuphumela ngaphandle lidinga i-MRI/MRV kanye ne-IV ephuthumayo ebulalayo ngokushesha.

Odokotela bawubona kanjani umehluko phakathi kwe-orbital cellulitis ne-cavernous sinus thrombosis?¶

Nakuba zombili izimo zingabangela iso elibomvu, elivuvukele, eliqhumayo (i-proptosis), imfiva, nokunyakaza kwamehlo okubuhlungu noma okulinganiselwe, izinkomba ezintathu zikhomba ngokuqondile i-cavernous sinus thrombosis: (1) Ukusabalala kwezinhlangothi zombili: ngenxa yokuthi izono ze-cavernous zesokunxele nesokudla zixhunywe phakathi komugqa ophakathi ngemithambo e-intercavernous, ukuvuvukala nokukhubazeka kweso kweqa kuya ehloni lokuqala elingama-48; (2) Ukuba ndikindiki kwe-Trigeminal nerve: ukuncinza noma ukuthinta kancane isiphongo sesiguli (CN V1) noma isihlathi esingaphezulu (CN V2) kuveza ukuba ndikindiki noma ukulahlekelwa i-corneal blink reflex; kanye (3) Ubuthi obunzima bemizwa, okuhlanganisa ikhanda elibuhlungu elibuhlungu ngemva kwamehlo, intamo eqinile, umfundi ovuleke/ovilaphayo, nokunyakaza kwamehlo aqandisiwe ngaphandle kwesilinganiso sokuvuvukala kwejwabu leso.

Yini ngempela imbangela engu-#1 ye-septic cavernous sinus thrombosis namuhla uma ingampintshi izinduna?¶

Ngaphambi kokuthi kutholwe ama-antibiotics, ukuminya amathumba ebusweni namakhala ("furuncles") ngaphakathi kweDanger Triangle kwakuyimbangela ehamba phambili ye-cavernous sinus thrombosis. Namuhla, nakuba amathumba emakhaleni asabangela amaphesenti angu-15 kuya kwangu-25 amacala, imbangela yesimanje engu-#1 (ebhekene namacala angaphezu kwamaphesenti angu-50 kuya kwangu-60) i-acute sphenoid sinusitis ye-bacterial kanye ne-etmoid sinusitis. Ngenxa yokuthi i-sphenoid sinus ihlezi ijule ngemuva kwekhala ihlukaniswe ne-cavernous sinus ngodonga olunamathambo olungaphansi kwamamilimitha angu-0.5 (okuvame ukuba nezikhala zemvelo ezincane kakhulu), ukutheleleka kwe-sinus okujulile okungalashwa kungaguguleka kudlulele ku-cavernous sinus.

Kungani odokotela benikeza amahlule egazi (i-Heparin) ehlule elithelelekile ngaphakathi kwe-cavernous sinus?¶

Uma uthi nhlá, ukunikeza igazi elincane ngesikhathi sokutheleleka kuzwakala kuyingozi, yingakho odokotela beqala ukwenza i-CT ne-MRI scan ukuze baqiniseke ukuthi akukho ukopha okusebenzayo kobuchopho. Lapho ukopha sekunqanyuliwe, i-heparin engafakwanga emthanjeni (noma i-heparin enesisindo esiphansi) kanye nemithi elwa namagciwane enedosi ephezulu idlala indima ebalulekile esindisa ukuphila: ivimba ihlule legazi le-septic ukuba lisabalale emithanjeni ye-intercavernous lingene kwelinye iso lesiguli noma lihlehle lingene kulo lonke uhlaka lwe-venous ebuchosheni livimbele ukuqhekeka kwemithambo, kuvimbele ukuqhekeka kwemithambo yobuchopho futhi kuvimbele ukuqhekeka kwemithambo yobuchopho, kuvimbele ukuqhekeka kwemithambo yobuchopho futhi kuvimbele ukuqhekeka kwemithambo yobuchopho. igcina imigudu ye-venous ivuliwe ukuze ama-antibiotic afakwe emthanjeni akwazi ukungena egciwaneni.

Yini okufanele ngiyenze uma nginethumba elibuhlungu ngaphakathi ekhaleni lami noma odebeni lwami olungenhla okwamanje?¶

Okokuqala, gcina izandla zakho kuso: ungalokothi ukuminyanise, ukuncinza, ukucosha, noma ukukuphopha ngenaliti. Gcoba indwangu yokugeza ehlanzekile, efudumele, emanzi endaweni imizuzu engu-15 izikhathi ezintathu kuya kwezine ngosuku ukuze ukhuthaze ukuphuma kwemvelo ngaphandle kwengcindezi. Bona udokotela ngosuku olufanayo ukuze uthole i-mupirocin ye-topical (2%) yamafutha ekhala kanye nama-antibiotic omlomo amboza i-Staphylococcus aureus (kanye ne-MRSA uma ivame emphakathini wakho). Uma uba nanoma yimuphi umkhuhlane, usakaze ububomvu ekhoneni leso lakho elingaphakathi, ikhanda elibuhlungu ngemuva kwamehlo akho, ukuvuvuka kwejwabu leso, noma ukubona kabili, qonda ngqo emnyangweni wezimo eziphuthumayo esibhedlela.
