Okulumwa omutwe mu kubwatuka, Okuvaamu omusaayi mu bitundu by’omubiri (Subarachnoid Hemorrhage), n’okukutuka kw’emisuwa gy’obwongo¶

Obulumi bw’omutwe obw’okubwatuka bwe mutwe ogw’okubwatuka, ogw’amaanyi ennyo ogukuba okuva mu kifo awatali wala ne gutuuka ku maanyi gagwo agasinga obunene ogwa \(10\text{-out-of-}10\) mu sekondi okutuuka ku sikonda 60, ng’okukuba mu ngalo okw’amangu okw’okubwatuka oba okukubwa emabega w’omutwe n’omuggo gwa baseball. Buli kulumwa omutwe ogw’okubwatuka kuba mbeera ya mangu ey’obujjanjabi etta obulamu okutuusa nga kikakasibwa nti si bwe kiri, kubanga kye kabonero akamanyiddwa ennyo aka okuvaamu omusaayi mu bitundu by’omubiri ebitali bya buvune (SAH) ekiva ku okukutuka kw’emisuwa gy’obwongo. Omusuwa gw’obwongo ogulinga ekizimba bwe gubutuka mu kifo ekijjudde amazzi ekyetoolodde obwongo, omusaayi gufuluma wansi wa puleesa y’emisuwa enzijuvu, ne gulinnyisa puleesa mu mutwe amangu ago. Awatali kulongoosa busimu oba emisuwa egy’omunda mu bwangu, omusuwa ogukutuse gutera okuddamu okuvaamu omusaayi mu ssaawa 6 ku 24 ezisooka, nga gutwala omuwendo gw’abafa ogusukka ebitundu 50 ku 70 ku buli 100 nga guzzeemu okukutuka.

Kino kikole kati¶

1. Kuba ennamba y'amangu mu kitundu kyo mu bwangu era olangirire nti "Suspected Subarachnoid Hemorrhage / Ruptured Brain Aneurysm." Kuba 911 mu Amerika ne Canada, 112 okwetoloola omukago gwa Bulaaya, 999 mu Bungereza, oba olabe byonna ennamba z’amangu. Saba ambyulensi ey’omulembe eyamba obulamu era saba entambula okugenda mu ddwaaliro eririna obusobozi bw’okulongoosa obusimu n’okuyingira mu by’obusimu (a Comprehensive Stroke Center).
2. Wandiika eddakiika entuufu omutwe gwe gwakuba. Oba eddwaaliro liyinza okugaana omusaayi mu bwongo mu ngeri ey’obukuumi nga likozesa CT scan ey’amangu yokka (eddirisa lya 6-Hour Ottawa SAH Rule) oba lirina n’okukola okuboola omugongo (spinal tap) kisinziira ku kumanya eddakiika entuufu omutwe gwe gwatandika.
3. Situla omutwe n’omubiri gw’omuntu okutuuka ku kkoona lya diguli 30 era okakasizza okusirika okw’omubiri okw’enkomeredde. Wandiika omutwe n’ebibegabega mpola ku mitto ku diguli 30 eziserengese ng’ensingo ekuumibwa nga egoloddwa mu layini eya wakati (nga tezikyusiddwa oba nga zifukamidde nnyo), omusaayi gw’emisuwa gusobole okufuluma obulungi okuva mu kiwanga ne wansi mu mutwe. Toleka muntu oyo kuyimirira, kutambula, kufukamira, kusesema nnyo, oba okunyigirizibwa ku kaabuyonjo (no Valsalva straining).
4. Mukwate eddagala lyonna eriweweeza ku bulumi ery’omu kamwa (naddala aspirin ne NSAIDs), emmere, n’amazzi. Omuntu mukuume nga tolina kintu kyonna mu kamwa (NPO) nga weetegekera okubudamya mu bwangu, okuziyira kw’emisuwa, oba okusala mu misuwa emitonotono, n’okuziyiza okusiiyibwa n’okufuuwa mu mawuggwe.
5. Dzikiza ekisenge, okumalawo amaloboozi gonna, era omuntu akuume nga mukkakkamu okuziyiza puleesa okulinnya. Omusaayi gwa subarachnoid gunyiiza nnyo obuwuka obubikka obwongo (meninges), ekivaako okuwulira ennyo ekitangaala (photophobia) n’okuwulira amaloboozi. Ziziza amataala, sirisa ttivvi n’amasimu, era oyogere mpola obulumi n’okutya bireme kulinnyisa puleesa ya systolic ne bifuuwa okuzimba okw’ekiseera ku misuwa.
6. Weetegereze nnyo ekibikka ky’eriiso ekigudde, ekituli ekigazi, okukonziba, oba okuzirika mu bwangu. Omuntu bw’asesema oba n’afuna otulo, biyiringisize mpola ku ludda lwe (nga omutwe n’ensingo bikwatagana) olwo omukutu gwe ogw’empewo gubeere nga muyonjo. Singa balekera awo okussa mu ngeri eya bulijjo, tandika mangu CPR.

Kiki ekibaawo ng'omusuwa gw'obwongo gukutuse: Pathophysiology ne "Sentinel Bleed".¶

1. Emisuwa egy'omu nsawo ("Berry") n'enkulungo ya Willis¶

Ebitundu nga 85 ku buli 100 eby’omusaayi ogufuluma mu bwongo mu ngeri eyeetongodde guva ku kukutuka kw’omusuwa gw’obwongo ogwa saccular (berry) cerebral aneurysm. Okwawukanako n’emisuwa eminene egy’ebinywa mu mikono n’amagulu, emisuwa emikulu ku musingi gw’obwongo (the Circle of Willis) girina ebisenge eby’ebweru ebigonvu ennyo era gituula nga giwaniriddwa mu mazzi cerebrospinal fluid (CSF) munda mu subarachnoid space. Oluvannyuma lw’emyaka egy’okunyigirizibwa kw’omusaayi, puleesa, okunywa sigala, oba obuzaale, ensawo eriko bbugwe omugonvu oba ekizimba kifuluma ku fooro y’emisuwa (ekifo ky’amatabi).

Ekyo ekigonvu ekiyitibwa aneurysm dome bwe kituuka n’okukutuka: - Omusaayi gw’emisuwa gukulukuta butereevu mu mazzi g’omu bwongo ku puleesa y’omusaayi (\(120\text{ okutuuka ku }200+\text{ mmHg}\)). - Mu sikonda ntono, puleesa eri munda mu kiwanga ekikaluba (intracranial pressure, oba ICP) egenda waggulu okutuusa kumpi lwe yenkana puleesa y’omusaayi mu misuwa. Amayengo gano aga puleesa ag’amangu gagolola ebitundu by’omubiri ebiyitibwa meninges ebiwulikika ku musingi gw’obwongo, ne bikola okulumwa omutwe okw’amangu, era emirundi mingi kayimiriza okutambula kw’omusaayi mu bwongo okumala akaseera katono, ekivaako okufiirwa okutegeera okw’ekiseera ekitono (syncope) mu balwadde 30 ku 50 ku buli 100. - Mu balwadde abawona okubutuka okwasooka, puleesa egwa munda mu kiwanga n’ensonga z’okuzimba mu kitundu zikola fragile fibrin-platelet plug ku maziga agali mu bbugwe w’emisuwa mu ddakiika 1 ku 3.

2. "Obulumi bw'omutwe gwa Sentinel" (Warning Leak): Eddirisa ly'okuwangaala erya wiiki 2¶

Ebitundu Abalwadde 20 ku 40 ku buli 100 abafuna okukutuka kw'emisuwa gy'obwongo mu ngeri ey'amaanyi, etta abantu baafuna "okulumwa omutwe ogw'okulabula" okutono (okukulukuta okulabula) ennaku 2 ku 21 emabega okwagobwa ng'omutwe omubi, okulumwa omutwe mu sinus, oba okunyigirizibwa mu bulago. - Mu sentinel bleed, enjatika entonotono egguka mu bbugwe w’emisuwa, n’ekulukuta akajiiko akatono ak’omusaayi mu kifo kya subarachnoid, oba ekisenge ky’emisuwa kiwanvuwa mangu (intramural hemorrhage). - Omuntu oyo afuna omutwe ogw’amangu, ogw’okubwatuka mu kaseera ako oguyinza okumala essaawa ntono okutuuka ku nnaku bbiri oba ssatu, oluusi n’okuziyira okutono oba okulumwa ensingo, nga tannatereera mpolampola. Olw’okuba omuntu oyo akyayinza okutambula n’okwogera, amira eddagala eriweweeza ku bulumi n’asigala awaka. - Lwaki okutegeera okulumwa omutwe gwa sentinel kitaasa obulamu: Omulwadde ajjanjabwa mu ddwaaliro oluvannyuma lw’okukulukuta kw’okulabula kwa sentinel (nga bakyali bazuukuse nnyo, abateekebwa mu kibinja kya Hunt and Hess Grade 1 oba 2) alina emikisa 85 ku 95 ku buli 100 okuwona ng’obusimu bukola bulungi. Singa okukulukuta okwo okw’okulabula kusiwuuka empisa era omusuwa ne guddamu okukutuka ennyo oluvannyuma lw’ennaku (Hunt and Hess Grade 4 oba 5), abalwadde 50 ku 80 ku buli 100 bafa oba basigala nga balema enkalakkalira.

3. Akabonero akalabula "Oculomotor Nerve Palsy" (Ekibikka ky'amaaso ekigwa + Omuyizi ogufuuwa) .¶

Akabonero kamu akalala ak’okulabula mu mubiri kayinza okulabika ne nga omusuwa tegunnakutuka ddala: - omusuwa oguwuliziganya ogw’emabega (PCM) aneurysm bwe gugaziwa, gunyiga butereevu ku obusimu obw’okusatu obw’omutwe (oculomotor nerve, CN III) emabega ddala w’eriiso. - Kino kireeta okusannyalala kw'obusimu obw'okusatu okuluma okw'amangu ku ludda olumu: ekibikka eky'okungulu kigwa ne kiggalwa (ptosis), ekikuta ky'eriiso kikyuka ne kidda ebweru ne wansi (okutunula "wansi n'ebweru", ekivaako okulaba emirundi ebiri), era omuyizi ku ludda olwo ne gugaziwa era nga gukaluba oba nga gunyweredde ku kitangaala (kubanga ebiwuzi by'amaaso ebiziyiza omuyizi bidduka ku ludda olw'ebweru rim y’obusimu obw’okusatu). - Etteeka: Omuntu yenna alumwa omutwe nga kigatta n’ekibikka ky’amaaso ekyakagwa oba ekikuta ekigaziye ku ludda olumu alina okuddusibwa amangu ddala mu kitongole ky’abalwadde ab’amangu okukeberebwa CT angiogram okukwata omusuwa ogugaziwa nga tegunnakutuka.

4. Ebirala Ebivaako Okulumwa Omutwe mu Kubwatuka kw’Okubwatuka kw’Obulamu¶

Ne bwe kiba nti okuzimba emisuwa mu bwongo si gwe musango, okulumwa omutwe olw’okubwatuka emirundi mingi kulaga obuzibu obulala obw’emisuwa munda mu kiwanga oba mu bulago: - Reversible Cerebral Vasoconstriction Syndrome (RCVS): Embeera ng'emisuwa gy'obwongo gisannyalala mu bwangu mu bitundutundu (nga girabika nga "omuguwa gw'obululu" ku angiogram), ekivaako okulumwa omutwe okuddamu okubwatuka mu wiiki 1 ku 2 nga kiva ku kunaaba, okukola ennyo, okusesema, okutuuka ku ntikko, oba eddagala erikola omusaayi (SSRIs, eddagala eriweweeza ku nnyindo, triptans oba enjaga). - Cerebral Venous Sinus Thrombosis (CVST): Omusaayi oguzimba emikutu eminene egy’okufulumya amazzi mu bwongo naddala mu kiseera ky’olubuto, mu kiseera ky’okuzaala, oba abakozesa eddagala eriziyiza okuzaala eririmu estrogen. - Cervical Artery Disection (Carotid or Vertebral Dissection): Okukutuka mu bbugwe w’omusuwa gw’ensingo oluvannyuma lw’okulumwa obutonotono, okutereeza ensingo mu ngeri y’okusiba, okusitula ennyo, oba okusesema, ekivaako okulumwa omutwe ku ludda olumu oba okulumwa ensingo ebiseera ebisinga nga kikwatagana ne Horner syndrome (omuyizi omutono n’ekibikka eky’okungulu okugwa katono ku ludda lwe lumu). - Pituitary Apoplexy: Okuvaamu omusaayi okw’amangu oba okusannyalala munda mu nseke y’omubiri ku musingi gw’obwongo, ekivaako okulumwa omutwe ogw’okubwatuka emabega w’amaaso, okufiirwa okulaba okw’amangu okw’okumpi mu maaso gombi (bitemporal hemianopsia), okulaba emirundi ebiri, n’okubulwa obulamu mu matigga acute cortisol deficiency (laba obuzibu bw’ekibumba n’empiso ey’amangu ey’obulwadde bwa Addison).

Okugeraageranya okujjuvu: Subarachnoid Hemorrhage vs. Migraine vs. Ebirala Ebivaako Okubwatuka kw’Okubwatuka¶

Si buli bulumi bw’omutwe obw’okubwatuka nti buba bwa misuwa egyakutuse, era si buli bulumi bw’omutwe obw’amaanyi nti bulumwa omutwe ogw’okubwatuka. Abasawo b’amangu bakozesa ebifaananyi bino wammanga okwawula emisuwa gy’obwongo egyakutuse okuva ku migraine ey’amaanyi n’okuva ku mbeera endala ez’amangu ez’emisuwa ezireeta n’okulumwa omutwe olw’okubwatuka (RCVS, CVST, Cervical Artery Dissection, and Pituitary Apoplexy):

Bendera emmyufu ez’obujjanjabi ezikakasibwa: Etteeka ly’okuvaamu omusaayi mu Ottawa Subarachnoid¶

Yakolebwa abanoonyereza ku ddagala ery’amangu mu Canada era n’ekkirizibwa American Heart Association / American Stroke Association (AHA/ASA) ne American College of Emergency Physicians (ACEP), Ottawa SAH Rule erina kumpi 100 ku buli 100 okuwuliziganya okuzuula abalwadde ki abalabula abalina omutwe ogw’amaanyi ogutali gwa kikangabwa ogutuuka ku maanyi agasinga mu 1 essaawa kyetaagisa okunoonyereza okw’amangu okw’abasawo ku kuvaamu omusaayi mu bitundu by’omubiri ebiyitibwa subarachnoid hemorrhage.

Singa omulwadde aba n'eKIMU ku bbendera emmyufu zonna 6 zino wammanga**, teziyinza kulongoosebwa awatali kulongoosa busimu mu ddwaaliro: 1. Emyaka \(40\text{ emyaka}\) oba okusingawo 2. Obulumi bw’ensingo oba okukaluba kw’ensingo (Weetegereze: omusaayi ogunyiiza amazzi g’omugongo gutwala essaawa 3 ku 12 okuleeta okukaluba kw’ensingo mu mubiri okwa nnamaddala, kale obutabaawo kukaluba mu bulago mu ssaawa 2 ezisooka tewali kugaana musaayi gwa misuwa) 3. Omulabye okubulwa okutegeera (okuzirika oba okugwa ng’omutwe gukubye) . 4. Okutandika nga okola amaanyi (okusitula ebizito, okudduka, okunyigirizibwa ku kaabuyonjo, okusesema fit, oba okwegatta) 5. Obulumi bw'omutwe obukuba okubwatuka (obulumi nga butuuka ku ntikko amangu ddala mu sikonda okutuuka ku ddakiika emu) 6. Okufukamira kw’ensingo okukoma ku kwekebejja (obutasobola kukwata ku kalevu okutuuka mu kifuba oba okusitula omutwe \(8\text{ centimeters}\) [\(3\text{ inches}\)] okuva ku kitanda)

Lwaki "Essaawa y'essaawa 6" kikulu: Head CT vs. Lumbar Puncture (Spinal Tap)¶

Bw’oyita 911 / 112 / 999 amangu ago n’owandiika eddakiika entuufu omutwe gwe gwatandika, okwata butereevu ku ngeri eddwaaliro gye liyinza okuzuulamu omusaayi mu butuufu era mu bwangu:

1. Munda mu ddirisa ly'essaawa 6 (CT Sensitivity -98.7% okutuuka ku 100%):
2. Omusaayi omuggya mu kifo kya subarachnoid gulabika nga mweru omutangaavu ku multi-slice non-contrast head CT scan ey’omulembe.
3. Okusinziira ku ndagiriro ya AHA/ASA, ACEP, ne UK NICE, singa CT scan y’omutwe ey’obulungi obw’amaanyi ekolebwa mu ssaawa 6 okuva mu ddakiika yennyini okulumwa omutwe ogw’okubwatuka kwe kwatandika era n’ataputibwa omukugu mu by’obusimu omukugu mu by’obusimu nga bulijjo, kigaana okuvaamu omusaayi ogw’amaanyi mu bitundu by’omubiri (acute subarachnoid hemorrhage) nga obutuufu obusukka mu bitundu 98.7 ku 99.9 ku buli 100 (wadde ng’abasawo bajja kukikola emirundi mingi bakyagattako CT Angiogram [CTA] y’emisuwa gy’omusaayi mu bwongo okukebera oba omusuwa ogutakutuse, okusalako emisuwa gy’omumwa gwa nnabaana, oba RCVS).
4. Essaawa ezisukka 6 oluvannyuma lw'okutandika (Lwaki CT Yokka Esobola Okusubwa Omusaayi):
5. Olw’okuba amazzi g’omu bwongo agalimu amazzi gatambula buli kiseera era ne ganaaba mu kifo ekiri wansi w’omugongo (nga geekyusa emirundi egiwerako olunaku), omusaayi omuggya gutandika okukendeera n’okufa ku CT scan eya bulijjo ng’essaawa ziyitawo:
   • Mu ssaawa 6: CT sensitivity eri \(98.7\%\text{ okutuuka ku }100\%\).
   • Ku ssaawa 12 ku 24: Obuwulize bwa CT bukka okutuuka ku \(90\%\text{ okutuuka ku }93\%\).
   • Ku nnaku 3 ku 5 (kitera okubaawo oluvannyuma lw’okulumwa omutwe ogwa sentinel): CT sensitivity ekendeera okutuuka ku \(50\%\text{ okutuuka ku }75\%\).
6. N'olwekyo, singa omulwadde alinda enkeera okugenda mu kisenge ky'abalwadde ab'amangu era nga CT scan ye eya bulijjo ey'omutwe "eba "ya bulijjo," CT scan eya bulijjo oluvannyuma lw'essaawa 6 TEGAGAANA misuwa gyakutuka. Ttiimu y’abalwadde ab’amangu erina okukola oba Lumbar Puncture (spinal tap) okunoonya obutoffaali obumyufu ne xanthochromia (pigment ya bilirubin eya kyenvu ekolebwa ng’obutoffaali obumyufu bumenyese mu mazzi g’omugongo, agalabika nga wayise essaawa 6 ku 12 oluvannyuma lw’okuvaamu omusaayi ne busigala nga bulabika okumala wiiki 2) ne/oba CT Angiogram (CTA) y’obwongo emisuwa emisuwa.

Ani asinga okubeera mu bulabe bw’okulwala emisuwa mu bwongo?¶

Okugabana ensonga zino ez’obulabe ez’obuzaale n’obujjanjabi n’abasawo abasookerwako n’abasawo b’omu kisenge eky’amangu kyanguya okukuba ebifaananyi by’emisuwa: - Ebyafaayo by’amaka ebya ddaala erisooka: Okubeera n’abooluganda babiri oba okusingawo ab’eddaala erisooka (omuzadde, muganda we, mwannyinaffe, oba omwana) abaali n’emisuwa gy’obwongo oba omusaayi ogufuluma mu bwongo kyongera ku bulabe bw’omuntu emirundi 4 okutuuka ku mirundi 8. - Obulwadde bw’ekibumba obuyitibwa Autosomal Dominant Polycystic Kidney Disease (ADPKD): Abalwadde nga 10 ku 15 ku buli 100 abalina obulwadde bw’ekibumba obuyitibwa polycystic kidney disease bakuuma emisuwa gy’obutunda mu mutwe. - Obuzibu bw’ebitundu by’omubiri n’emisuwa: Obulwadde bwa Ehlers-Danlos (Type IV), Obulwadde bwa Marfan, Obulwadde bwa Loeys-Dietz, obulwadde bw’ebinywa ebiyitibwa fibromuscular dysplasia (FMD), n’okuzimba omusuwa gw’omusaayi. - Ensonga z’akabi ez’amaanyi ezikyusibwa: Okunywa sigala (ekintu ekimu ekisinga amaanyi ekiyinza okukyusibwamu ekivaako emisuwa okutondebwawo, okukula, n’okukutuka), puleesa etafugibwa, okukozesa omwenge omungi, ne okukozesa cocaine oba methamphetamine (ekilinnyisa puleesa mu ngeri ey’amaanyi ate nga kinafuwa ebisenge by’emisuwa). - Okuzimba emisuwa egy’emabega: Abalwadde abalina emisuwa egisukka mu bitundu 20 ku buli 100 balina emisuwa mingi (mirror aneurysms ku njuyi zombi eza Circle of Willis).

Obujjanjabi obusookerwako mu mutendera ku mutendera nga bw’olinda ambyulensi¶

Buli kikolwa nga tonnagenda mu ddwaaliro mu kiseera ky’omusaayi oguteeberezebwa okuva mu subarachnoid kigendereddwamu okuziyiza okuddamu okukutuka kw’emisuwa ne okukuuma omukutu gw’empewo.

Omutendera 1: Okuteeka mu kifo (Etteeka lya Diguli 30 eza wakati) .¶

• Yamba omuntu oyo okugalamira ku kitanda oba sofa nga omutwe gwe n'omubiri gwe ogwa waggulu biwanise mu kkoona lya diguli 30.
• Kuuma omutwe gwabwe n’ensingo nga bikwatagana nga bigolokofu mu layini eya wakati (nga bitunudde butereevu mu maaso, nga tebikyusiddwa nnyo ku kkono oba ku ddyo, era nga tewali kkoola nnywevu mu bulago). Okukyusa ensingo kinyigiriza nnyo emisuwa egy’omunda egy’omu kifuba, ne kiziyiza omusaayi okufuluma mu mutwe n’okulinnyisa puleesa mu mutwe.
• Omuntu bw’aba asesema, otulo otuyitiridde, oba nga tategeera: Amangu ago muteeke ku ludda lwe mu mbeera ya okuwona (ng’okuuma omutwe nga guwaniriddwa nga gukwatagana n’omugongo) olwo okusesema kuleme kussa mu mawuggwe.

Omutendera 2: Okussa mu nkola "Zero Valsalva" ne Low Sensory Stimulation¶

• Lwaki okuddamu okukutuka kubaawo: Ekizimba ky’omusaayi ekitali kinywevu ekiziba ekituli mu kisenge ky’emisuwa ekikutuse kikwatibwa mu kifo kyokka olw’enzikiriziganya wakati wa puleesa eri munda mu musuwa ne puleesa eri ebweru w’omusuwa. Singa omuntu oyo asika, n’asesema n’amaanyi, n’asesema nnyo, n’ayimirira okutambula, oba n’ateera, puleesa ye ey’omusaayi (systolic blood pressure) erinnya waggulu wa \(180\text{ okutuuka ku }220\text{ mmHg}\), n’efuuwa ekizimba okuva ku misuwa (re-rupture).
• Ggyako amataala agali waggulu, ggalawo ebizibiti by’amadirisa, ggyako ttivvi, kuuma ebisolo by’omu nnyumba n’abatunuulidde nga beeraliikirivu nga tebali mu kisenge, era olagirire omuntu oyo okussa mpola ng’ayita mu kamwa akaggule (nga takwata mukka gwe).

Omutendera 3: Kebera n’okuwandiika obubonero bw’obusimu (Hunt & Hess / WFNS Clues) .¶

Kebera obubonero buno obuna obwangu obw’obujjanjabi era obuwandiike eri abajjanjabi abasookerwako: 1. Eddaala ly’okubeera obulindaala (Glasgow Coma Scale): Amaaso gaabwe gazibuka mu ngeri eyeetongodde? Bamanyi amannya gaabwe, ekifo we babeera, n’omwezi? 2. Okukebera abayizi: Yaka ettaala y’ekisenge eya bulijjo (si ttaala eziba amaaso butereevu mu liiso eritya ekitangaala okuggyako ng’ozirise) oba tunuulira mpola abayizi bombi. Zibeera zenkanankana mu bunene, oba omuyizi gumu munene mu ngeri eyeetegeerekeka (ngagaziyiziddwa) oba nga gugatta n'ekibikka eky'okungulu ekigwa? 3. Limb Strength & Speech: Basobola okusika emikono gyo gyombi kyenkanyi ne boogera bulungi? 4. Heart Rhythm Warning (Neurogenic Stunned Myocardium): Massive subarachnoid hemorrhage efulumya omusulo omunene ennyo ogwa catecholamines (adrenaline) butereevu ku binywa by’omutima, ekiyinza okuvaako okutaataaganyizibwa kw’omutima okw’akabi (arrhythmias), flash pulmonary edema, oba omutima okuyimirira mu bwangu mu kiseera ky’okukutuka. Weekuume nnyo ku kussa n’okukuba buli ddakiika okutuusa ng’abajjanjabi abasookerwako bassaako ekyuma ekikebera omutima.

Omutendera 4: Ebibaawo mu Ddwaliro (Okukoona, Okusala, ne Nimodipine) .¶

Kale ab’omu maka bamanyi kye basuubira nga batuuse mu Comprehensive Stroke / Neurosurgical Center: - Okufuga puleesa mu bwangu: Abasawo bakozesa eddagala eriweebwa amangu mu misuwa (nga nicardipine, clevidipine, oba labetalol) okuleeta puleesa y’omusaayi wansi mu ngeri ennungi wansi wa \(140\text{ okutuuka ku }160\text{ mmHg}\) okuziyiza okuddamu okuvaamu omusaayi nga omusuwa tegunnanyweza. - Okukuuma Aneurysm mu Ssaawa 24: - Endovascular Coiling: Omukugu mu by’obusimu (neuro-interventionalist) ayingiza microcatheter okuva mu musuwa gw’engalo oba mu kifuba waggulu mu misuwa gy’obwongo n’agipakira ne coils za platinum ennyogovu (oba n’ateeka stent/web device ekyusa amazzi) okugisiba okuva munda nga tagguddewo kiwanga. - Microsurgical Clipping: Omusawo alongoosa obusimu alongoosa omutwe n’ateeka akatundu akatono aka titanium clip okubuna ensingo y’omusuwa okugyawula enkalakkalira okuva mu kutambula kw’omusaayi. - Okuziyiza Hydrocephalus ne Delayed Cerebral Vasospasm: Abasawo bawandiika nimodipine mu kamwa buli ssaawa 4 okumala ennaku 21 (ekiziyiza emikutu gya calcium kyokka ekikakasibwa okukuuma obutoffaali bw’obwongo okuva ku kulwawo okusannyalala kw’emisuwa ekituuka ku ntikko wakati wa ennaku 4 ne 14 oluvannyuma lw’okuvaamu omusaayi mu misuwa) era ayinza okuteeka external ventricular drain (EVD) singa omusaayi guziyiza okufulumya amazzi mu mugongo (acute hydrocephalus).

Ekiwandiiko ky’empuliziganya ekituufu ku 911 / 112 / 999 ne Hospital Triage¶

Kozesa ebigambo bino ebituufu eby’obujjanjabi olwo omusindika n’omusawo w’okusunsulamu bategeere mangu embeera ey’amangu ey’okulongoosa obusimu ekwata ekiseera okusinga okulumwa omutwe okutali kwa bulabe:

• Bw'oba oyita ku ssimu 911 / 112 / 999:

  *"Nneetaaga ambyulensi ey'amangu ku [Endagiriro entuufu]. Omulwadde wa myaka [Emyaka] [omusajja/omukazi] eyafuna okulumwa omutwe okw'amangu, 10-ku-10 okw'okubwatuka kw'okubwatuka mu [Exact Time] okwatuuka ku buzibu obusinga mu sikonda. [Ye/Ye] era yafuna [okuzirika okumpi / okusiiyibwa / okulumwa ensingo / ekibikka ky'amaaso ekikka / okutandika mu kiseera ky’okusitula ebintu ebizito].

• Bw'oba oyogera ne Emergency Department Triage Nurse (naddala ku muntu ateeberezebwa okuba "Sentinel Leak"):

  "Omulwadde ono yeetaaga okukola amangu Subarachnoid Hemorrhage workup wansi w'etteeka lya Ottawa SAH. Ku [Exact Time], [ye/ye] yalina okulumwa omutwe okw'amangu okw'okubwatuka okwatuuka ku ntikko mu sikonda ezitasukka 60, nga kuwerekerwako [emyaka egisukka mu 40 / obulumi mu bulago / okutandika okufuba / okubulwa okutegeera mu bufunze]. Wadde ng'obulumi bulina katono erongooseddwa, tweraliikirivu olw'okukulukuta kw'emisuwa gy'obwongo egya sentinel."

Olukalala lw’okukebera okwetegekera embeera ez’amangu ng’olinda abajjanjabi abasookerwako¶

• Essaawa entuufu ey’okutandika okulumwa omutwe ewandiikiddwa wansi (esalawo oba omulwadde ali munda mu ddirisa lya CT sensitivity ery’essaawa 6).
• Omulwadde kye yali akola ku sikonda yennyini omutwe gwe gwakubye (okusitula, okusesema, okunyigirizibwa mu kaabuyonjo, okukola dduyiro, oba okuwummula).
• Oba omulwadde yaddugala okumala akaseera katono oba yagwa nga atandise.
• Olukalala olujjuvu olw’eddagala eriweweeza ku musaayi oba eriweweeza ku buwuka obuleeta omusaayi (warfarin, apixaban, rivaroxaban, dabigatran, clopidogrel, aspirin, oba NSAIDs) eddwaaliro lisobole okugaba eddagala eriweweeza ku musaayi mu bwangu singa omusaayi gukakasibwa.
• Ebyafaayo byonna eby'amaka eby'emisuwa gy'obwongo oba obulwadde bw'ekibumba obuyitibwa polycystic kidney disease weetegereza.

Ebibuuzo ebitera okubuuzibwa¶

Kiki ddala "okulumwa omutwe olw'okubwatuka" kitegeeza ki, era kyawukana kitya ku omutwe omubi?¶

Ekintu ekitegeeza okulumwa omutwe olw’okubwatuka si ngeri bulumi gye buba obw’amaanyi yokka, wabula engeri gye butuuka ku sipiidi ey’amaanyi: omutwe ogw’okubwatuka guva ku bulumi obutaliimu okutuuka ku bulumi obusinga obunene 10 ku 10 mu sikonda okutuuka ku sikonda 60, ng’okukuba mu ngalo okw’amangu okw’okubwatuka oba okukuba ku mutwe. Okwawukanako n’ekyo, n’omutwe ogusinga okuluma gutandika mpolampola era gutwala eddakiika 30 okutuuka ku ssaawa eziwerako okuzimba okutuuka ku ntikko.

"Obulumi bw'omutwe gwa sentinel" kye ki, era lwaki kyabulabe nnyo okubuusa amaaso?¶

Obulumi bw’omutwe obuyitibwa sentinel headache (oba okukulukuta okw’okulabula) kwe kulumwa omutwe ogw’amangu ogw’okubwatuka kw’okubwatuka okuleetebwa okukutuka oba okugolola okutono okw’okulabula mu bbugwe w’omusuwa gw’obwongo ng’ennaku 2 ku 21 omusuwa tegunnakutuka. Olw’okuba okukulukuta kwa sentinel kufulumya omusaayi mutono gwokka, omuntu oyo ayinza okuwulira ng’atereera oluvannyuma lw’olunaku lumu oba bbiri n’akikyamusa nti alina omutwe omuzito; okukwata omusulo ogukulukuta mu kisenge ky’abalwadde ab’amangu kisobozesa abasawo okukoola oba okusala emisuwa nga bawangaala ebitundu 85 ku 95 ku buli 100 nga tebannaba kukutuka kwa maanyi okutta.

Lwaki sisobola kumira aspirin oba ibuprofen ku mutwe ogw’amaanyi ogw’amangu?¶

Omusuwa gw’obwongo bwe gusooka okukulukuta oba okukutuka, akatundu akatono ennyo akatali kanywevu akayitibwa platelets z’omusaayi ne fibrin ke kalemesa omusuwa okuyiwa omusaayi obutasalako mu kiwanga. Okumira aspirin, ibuprofen oba naproxen kilemesa obutoffaali obukola omusaayi, kinafuya okuzimba okwo okw’ekiseera, era kyongera nnyo obulabe bw’okuddamu okuvaamu omusaayi mu bwongo mu ngeri ey’akatyabaga, etta omuntu.

Bwe kiba nti CT scan mu ddwaaliro kya bulijjo, lwaki abasawo bakyayinza okukuwa amagezi okukozesa tap y’omugongo (lumbar puncture) oba CT angiogram?¶

CT scan y’omutwe etali ya njawulo kumpi ntuufu kumpi ebitundu 99 ku 100 ku kulaba omusaayi omuggya ogwa subarachnoid singa sikaani ekolebwa mu ssaawa 6 zokka okuva mu ddakiika entuufu omutwe lwe gwatandika. Oluvannyuma lw’essaawa 6, amazzi g’omugongo agatambula gatandika okunaaba n’okukendeeza ku musaayi olwo CT scan eya bulijjo esobole okusubwa omusaayi; okukola okuboola omugongo kizuula obutoffaali obumyufu obutonotono ne langi ya kyenvu (xanthochromia) okumala wiiki 2, ate CT angiogram elaba butereevu emisuwa okuzuula emisuwa gyennyini.
