Hypothermia oo hoos u dhaca, si fudud u maarayn, iyo wadnaha oo istaaga¶

Heerarka shilalka daran ee daran waa mid ka mid ah xaaladaha degdegga ah ee caafimaad ee ugu halista badan ee lala kulmo goobidda iyo samatabbixinta, daawada cidlada, iyo masiibooyinka magaalada jiilaalka. Marka heerkulka jidhka xuduntu hoos uga dhaco 35°C (95°F), jidhka bini'aadamka waxa uu maraa decompensation jireed oo horumarsan. Heerarka dheef-shiid kiimikaadka ayaa hoos u dhacaya, wax soo saarka wadnaha oo hoos u dhaca, neefsashadu waa yaraataa, habka dhexe ee neerfayaasha ayaa si joogto ah u xirma.

Si kastaba ha ahaatee, khatarta ugu khatarta badan ee maareynta hypothermia waxay badanaa dhacdaa inta lagu jiro samatabbixinta iyo dib u kululaynta. Samatabbixiyeyaasha kacsada, ruxaya, ama qiyaas ahaan dhaqaaqa bukaan aad u daran ayaa kicin kara fibrillation degdega ah, oo u dira xanaaq badan, wadne qaboojinaya wadne istaag oo dilaa ah. Sidoo kale, kulaylka dibadda ee aan habboonayn ee addimada qabow waxay keeni kartaa hoos u dhac, halkaasoo fadhiid, qaboojin, dhiig aashitada ka timaadda cidhifyada uu dib ugu soo laabto xudunta, sii qaboojinta wadnaha oo keenta burburka wadnaha. Fahmida physiology-ga ka dib, baahida buuxda ee maaraynta bukaanka ee fudud, nidaamka habaynta Swiss, iyo farqiga u dhexeeya dib-u-soo-celinta asaasiga ah iyo firfircoon waxay macnaheedu noqon kartaa faraqa u dhexeeya nolosha iyo dhimashada.

Hadda samee tan¶

1. U laxari bukaanka hypothermic si aad u qallafsan, qalliin. Yaree dhaqdhaqaaqa jirka oo dhan; Weligaa ha u oggolaan in bukaanku socdo, istaago, si degdeg ah u fadhiisto, ama sameeyo dadaal jireed.
2. Kahortagga luminta kulaylka dheeraadka ah adiga oo ka saara bukaanka deegaanka qabowga leh. Ka ilaali qofka dabaysha, qoyaanka, iyo qabowga dhulka adiga oo abuuraya duudduuban uumiga-barrier Burrito ah oo dahaaran iyadoo la isticmaalayo daamur, bacaha lagu seexdo, iyo bustayaal bireed.
3. Bukaanka si adag u dhig. Shakhsigu si buuxda u dhig si aad uga hortagto isku urursi degdeg ah oo lafaha ah ee dhiiga maskaxda iyo si aad u yarayso cadaadiska wadnaha ee myocardium oo qabow, xanaaq badan.
4. Weligaa ha xoqin, duugin, ha marin kulayl toos ah gacmaha ama lugaha. Diirinta ama xoqidda addimada durugsan waxay sababtaa vasodilation degdeg ah, barafaysan, dhiig aashito ah si toos ah wadnaha iyo kicinta dhibic dhimasho ah.
5. ** Ka hubi garaaca wadnaha iyo neefsiga 60 ilbiriqsi oo buuxa.** Dheef-shiid kiimikaad ayaa hoos u dhigaya calaamadaha jir ahaaneed ilaa heerar aan la fahmi karin; qaado daqiiqad buuxda ka hor inta aanad soo gabagabeynin bukaanku waa wadne istaag.
6. Bilow CPR joogto ah haddii uu bukaanku run ahaantii yahay mid garaaca wadnaha oo wac diritaanka degdega ah. Haddii aan la helin garaaca wadnaha 60 ilbiriqsi ka dib, billow cadaadin laabta isla markaaba sii wad adoon joogsan inta lagu jiro gaadiidka isbitaalka oo leh dib u soo celin ka baxsan jidhka.

Cilmi-nafsiga ee qaboojinta xudunta u ah: habka is-habaynta Swiss¶

Hypothermia shilka ah waxaa lagu qeexaa hoos u dhac aan qasab ahayn ee heerkulka jidhka xudunta u ah oo ka hooseeya 35 °C (95 °F). Sababtoo ah in si sax ah loo cabbiro heerkulka asaasiga ah ee jawiga isbitaalka ka hor waxay u baahan tahay baaritaanka kuleyliyaha hunguriga ama malawadka, daaweeyayaasha waxay ku tiirsan yihiin Nidaamka Marxaladaynta Swiss ee dib loo eegay ee Shilalka Hypothermia. Waxaa soo saaray Guddiga Caalamiga ah ee Daawada Degdegga ah ee Buuraha (ICAR MEDCOM), nidaamkan habayntu waxa uu xidhiidhiyaa calamadaha caafimaad ee la arki karo oo leh xadhkaha heerkulka xudunta ah waxana uu tilmaamayaa waxqabadyada goobta.

Marxaladda I: Dhir-xumo fudud (35 °C ilaa 32 ° C / 95 ° F ilaa 90 ° F)¶

Marxaladdan, difaaca heerkulbeegga jirka ayaa si buuxda u shaqaynaya:

Bukaanku waa miyir qabaa, feejigan, oo awood u leh wada-xiriirka caadiga ah ee afka ah, in kasta oo dareen-la'aan fudud, caajisnimo, ama hadal dhuuban laga yaabo inay muuqato.

Thermogenesis gariirida ugu badan ayaa jirta. Muruqyada murqaha ah ee aan ikhtiyaarka lahayn waxay kordhin kartaa wax soo saarka kulaylka dheef-shiid kiimikaadka 400 ilaa 500 boqolkiiba ka sarreeya heerka aasaasiga ah.

Calaamadaha muhiimka ah waxay muujinayaan diiqad qabow oo uu keeno: tachycardia ( garaaca wadnaha degdega ah ), tachypnea (neefsasho degdeg ah), iyo cadaadiska dhiigga oo sarreeya.

diuresis qabow ayaa dhaca. Vasoconstriction peripheral wuxuu kordhiyaa mugga dhiigga dhexe, taasoo keenta kelyaha inay shaandheeyaan xaddi badan oo kaadi ah oo la miiray, taasoo keenta hypovolemia habaysan iyo fuuqbax.

Bukaannada ku jira marxaladda 1aad waxay dhalin karaan kuleylkooda waxayna ka soo kaban doonaan dib u diirimaad dibadda ah oo aan caadi ahayn haddii la siiyo dahaar qallalan iyo nafaqo kaloriin sare leh.

Marxaladda II: Heerkul dhexdhexaad ah (32 ° C ilaa 28 ° C / 90 ° F ilaa 82 ° F)¶

Marka la eego hypothermia dhexdhexaad ah, hababka heerkulbeegga jirka ayaa bilaabaya inay fashilmaan:

Gariirku gabi ahaanba wuu joogsadaa. Ka hooseeya 32 °C (90 °F), bakhaarada glycogen ee muruqyada lafaha way daalaan, iyo hypothalamus waxay luminaysaa awoodeeda iskudubarid heerkulbeegga gariiraya. Gariir la'aan, bukaanku ma dhalin karo kulayl gudaha ah.

Xaaladda maskaxdu si degdeg ah ayay u xumaataa. Bukaanku waxa uu noqdaa mid aad u jahawareersan, isku xidhid la'aan ("cumbles": fumbles, mumbles, tumbles), dagaal badan, ama indho la'aan.

Labbis iska dhigis ah ayaa dhici karta. Hoosudhaca Hypothalamic wuxuu keenaa vasodilation degdeg ah oo aan habboonayn, taasoo siinaysa bukaanka qaboojiya dareen been ah oo kulayl daran, taasoo ku kallifta inay iska siibaan dharka isla markaaba ka hor intaanay dumin.

Calaamadaha muhiimka ah ayaa hoos u dhigaya: bradycardia ( garaaca wadnaha oo gaabis ah ), hypoventilation (neefsasho gaabis ah, neefsasho gaaban), iyo hypotension horumarsan.

Myocardium wuxuu noqdaa mid xanaaq badan oo u nugul arrhythmogenesis farsamaysan. Bukaannada ku jira Marxaladda II waxay u baahan yihiin in si fudud loo maareeyo iyo kulaylka xudunta u ah dibadda.

Heerka III: Hypothermia daran (28 ° C ilaa 24 ° C / 82 ° F ilaa 75 ° F)¶

Hypothermia daran waxay ka dhigan tahay xidhidh dheef-shiid kiimikaad qoto dheer oo xuduud la leh dhimashada muuqata:

Bukaanku gabi ahaanba waa miyir daboolan yahay oo aan ka jawaabin kicinta afka ama xanuunka.

Dareen-celinta way baaba'aysaa; ardaydu waxa laga yaabaa in ay balaadhaan oo ay gebi ahaanba aan ka falcelinaynin iftiinka, iyaga oo iska ekaysiinaya dhimashada maskaxda.

Wax soo saarka wadnuhu wuxuu hoos ugu dhacaa in ka yar 30 boqolkiiba heerka aasaasiga ah. garaaca garaaca wadnaha waa daciif, dun leh, oo si gaar ah u gaabis ah (badanaa 10 ilaa 20 garaac daqiiqaddii).

Neefsashada kediska ahi waxay hoos u dhigtaa 2 ilaa 4 neefsasho daqiiqadii, inta badan waxay la timaadaa hakas dheer oo soconaya 15 ilaa 30 ilbiriqsi inta u dhaxaysa neefsashada.

Muruqyadu waxay noqdaan kuwo adag, oo soo bandhigaya sida qallafsanaanta qabow ee keentay taas oo si fudud loogu khaldi karo mortis adag ee dhimashada ka dib.

Wadnaha ayaa ku sugan xaalad koronto oo aad u jilicsan. Xataa jug yar oo kanetic ah ayaa isla markiiba kicin karta fibrillation ventricular. Bukaannada Heerka III waxay u baahan yihiin daad-gureynta degdega ah ee xarun caafimaad oo heer jaamacadeed ah oo u qalabaysan dib u kululaynta gudaha ee firfircoon.

Marxaladda IV: Dhimashada hoose ee hypothermia/dhimashada muuqata (ka hooseeya 24 °C / 75 °F)¶

Marxaladda IV, calaamadaha caafimaad ee nolosha ayaa maqan ama lama ogaan karo:

Bukaanku wuxuu u muuqdaa mid dhintay: garaaca wadnaha, aapneic, qabow sida dhagax oo kale, oo leh arday kala go'an iyo qallafsanaan qotodheer oo muruqa ah.

Dhaqdhaqaaqa korantada ee wadnaha wuxuu ka koobnaan karaa fibrillation ventricular fibrillation ama asystole muuqda oo ku saabsan electrocardiograms caadiga ah.

Si kastaba ha ahaatee, baahida dheef-shiid kiimikaad ee hypothermia qoto dheer ayaa hoos ugu dhacda in ka yar 10 boqolkiiba asaasiga ah. Heerkulka xudunta u ah aadka u hooseeya, maskaxda iyo wadnuhu waxay ku noolaan karaan muddo dheer oo wadne joogsi la'aan dhaawac ischemic hypoxic joogto ah.

Bukaanka u muuqda inay ku dhinteen xaaladahan waxay samayn karaan bogsasho buuxda oo neerfaha haddii dib u soo kicinta wadnaha sambabada si joogto ah loo ilaaliyo ilaa dib u kululaynta gudaha ee firfircoon laga helayo taageerada nolosha jidhka ka baxsan (ECLS).

ifafaale ka dambeeya: biophysics iyo wareegga dhiigga oo burburay¶

Dhacdada ka dib ayaa ah hoos u dhaca hoos u dhaca ee heerkulka asaasiga ah ka dib markii bukaan laga soo badbaadiyay qabowga, ama inta lagu jiro marxaladaha hore ee dib u soo celinta dibadda.

Inkasta oo bukaanka la geliyo ambalaas kulul ama lagu duudduubay buste diirran, heerkulka xubnaha xudunta u ah (maskaxda, wadnaha, sambabada) waxay ku sii socon kartaa hoos u dhaca 2 ° C ilaa 5 ° C (3.6 ° F ilaa 9 ° F) 30 ilaa 60 daqiiqo ee xiga. Bukaanka heerkulkiisa xudunta u yahay mar horeba ku dul wareegaya meel halis ah 28 °C (82 °F), hoos u dhac 3-degree ah oo dheeraad ah ayaa wadnaha gelinaya xirid qoto dheer oo fibrillation ah.

Mechanisms wadista dhibic danbe: conduction lid ku ah wareegga¶

Afterdrop waxaa wata laba hab oo nafsiyeed oo kala duwan:

Sinaanta heerkulka kuleylku wuxuu ku shaqeeyaa wareejinta kulaylka jirka saafiga ah. Marka qofku si xun u qaboojiyo, heerkulka gudaha ayaa jira: xubnaha xudunta u ah waa qabow, laakiin muruqa qoto dheer iyo unugyada subcutaneous ee qolofka dibadda ayaa xitaa qabow. Marka kulaylka ka soo baxa maqaarka maqaarka la joojiyo, haynta kulaylku waxay sii socotaa dhaqdhaqaaqa kuleylka ka soo baxa diirka diirran oo u baxa qolofka qabow ilaa inta dheellitirka heerkulka laga gaarayo cufka jirka oo dhan.

Wareegga wareega wareega ee hadda ka soo horjeeda wareegtada ayaa ah habka ugu khatarta badan. Inta lagu jiro soo-gaadhista qabow ee qoto dheer, vasoconstriction durugsan ee durugsan ayaa go'doomiya dhiiga xudunta dhexdeeda, taasoo ka tagta cidhifyada qabow, ischaemic, iyo fadhiid.

Haddii samatabbixiyeyaashu ay sameeyaan khalad masiibo ah oo ay si firfircoon u diiriyaan gacmaha iyo lugaha bukaanka, ama haddii bukaanka loo oggolaado inuu socdo, xididdada dhiigga ee durugsan ayaa si degdeg ah u kala baxa:

Dhiiga halbowlayaasha diirran ayaa u soo yaacaya xagga darafyada qabowga.

Halkaa, dhiiggu wuxuu ku qaboojiyaa heerkul ku dhow oo wuxuu soo qaataa tiro badan oo ah qashinka dheef-shiid kiimikaadka oo ku ururay muruqa lafaha ischaemic: lactic acid, ions hydrogen, carbon dioxide, iyo ions potassium ee unugyada muruqa dhaawacan.

Qabowgan, aashitada aadka u sarreeya, dhiigga xididdada dhiigga ee hyperkalemic ayaa dib loogu soo shubaa xididdada hoose ee hoose iyo kan sare oo toos ah atrium midig ee wadnaha.

Imaatinka kediska ah ee daadkan xididka barafka ah ayaa qaboojiya myocardium dhowr darajo ilbidhiqsiyo gudahood, taasoo ka yaabisay qanjidhada sinoatrial iyo atrioventricular oo soo da'aya wadno xanuun wadnaha ah oo dilaa ah.

Isla mar ahaantaana, balaadhinta lama filaanka ah ee geedka xididada xididada xididada ayaa sababa hypovolemia ba'an wareegga dhiigga, oo loo yaqaan shoogga dib u soo celinta, hoos u dhigista cadaadiska dhiigga halbowlaha eber.

Fibrillation Ventricular iyo hypothermic myocardium ee xanaaqa¶

Dhaqdhaqaaqa caafimaad ee caadiga ah, dhaqdhaqaaqa jirka, rogroga, ama gaadiidka ayaa saameyn yar ku leh laxanka wadnaha. Si kastaba ha ahaatee, hypothermia daran, si kastaba ha ahaatee, sifooyinka biophysical ee unugyada wadnaha ayaa asal ahaan bedelay.

Wadnaha hypothermic waa koronto ahaan aan degganayn, xubin aad u kacsan.

Isbeddelka Electrophysiological ee wadnaha qabow¶

Marka heerkulka myocardial uu hoos uga dhaco 30 ° C (86 ° F), cilladaha gacanta ee kala duwan ayaa ka soo baxa nidaamka wareegga wadnaha:

Depolarization iyo repolarization wejiyada waxqabadka wadnaha ee suurtogalka ah ayaa si muuqata u sii dheeraaday sababtoo ah matoorada ion-ka ee enzyme-ka (sida bamka sodium-potassium ATPase) ayaa hoos u dhacaya.

Xawaaraha samaynta iyada oo loo marayo xidhmada fiilooyinka isaga iyo Purkinje ayaa hoos u dhigaya, abuurista kala duwanaansho heer gobol oo baaxad leh oo ka soo horjeedda korantada ee guud ahaan myocardium ventricular.

Electrocardiogram (ECG) wuxuu muujinayaa calaamadaha caadiga ah ee hypothermia: bradycardia sinus oo sii socda, PR interval prolongation, QRS fidinta, kordhinta dhexda QT, iyo muuqaalka mowjadaha Osborn ee pathognomonic (J-mowjadaha), leexleexyo togan oo caan ah oo ka dhacaya isgoyska u dhexeeya dhismaha QRS iyo qaybta ST.

Sababtoo ah qaybaha kala duwan ee gidaarka hawo-mareenka ayaa dib ugu soo noqda heerar aan sinnayn, wadnuhu wuxuu noqonayaa mid si gaar ah ugu nugul dhacdada R-on-T. Gariir yar oo makaanikada ah ama isbeddelka dheef-shiid kiimikaadka degdega ah wuxuu kicin karaa habacsanaan, dhaqdhaqaaq wareega wareegga wareegga korantada, isla markiiba bilaabaya fibrillation ventricular.

Electrocardiographic Features of Severe Hypothermia:
-----------------------------------------------------------
1. Severe sinus bradycardia (15 to 30 beats per minute).
2. Osborne wave (J-wave) at the QRS-ST junction.
3. Prolonged PR, QRS, and QTc intervals.
4. Atrial fibrillation with slow ventricular response.
5. High susceptibility to sudden Ventricular Fibrillation (VF).

Waa maxay sababta si fudud ula dhaqmida ay tahay waajib caafimaad oo adag¶

Sababtoo ah myocardium waa mid aad xasaasi u ah, dhaqdhaqaaqa jireed wuxuu u dhaqmi karaa kicinta farsamada dibadda ee fibrillation ventricular:

Dhaqdhaqaaq kasta oo qallafsan, barar fiiqan, ka guur degdeg ah oo laga bilaabo jiifsiga oo loo fadhiisto, ama duugista xoogga leh ee jidhku waxay si farsamaysan u dhimi kartaa darbiga myocardial-ka ee xanaaqa, kicinta wadnaha oo degdeg ah.

Samatabbixiyeyaashu waa inay u hoggaansamaan mabda'a "dabcaanta qalliinka":

1. Weligaa ha u oggolaan in bukaanku istaago ama socdo, xitaa haddii ay sheeganayaan inay dareemayaan karti.
2. Bukaanka si adag u dhig (gabarka si siman). U wareejinta bukaan-jiifka ku-meel-gaadhka ah ee fadhiga waxay sababtaa hypotension degdeg ah, gooynta halbowlayaasha iyo socodka dhiigga maskaxda.
3. Dhaqaaq bukaanka adigoo isticmaalaya maneuvers log-roll ama boorso dhabarka ah oo adag, adoo ku haynaya laf dhabarta, madaxa, iyo jirkooda hal diyaarad oo adag iyada oo aan qalloocin.
4. Si tartiib ah ugu raac dhul xun. Samatabbixiyeyaasha sida barele waa in ay ku socdaan si ka baxsan talaabada si ay uga fogaadaan boodboodka qashinka.
5. Ka fogow faragelinta aan loo baahnayn ee goobta. Ha isku dayin nuugista marin-haweedka gardarrada ah ama tubbada endotracheal qallafsan ilaa neefsashadu gabi ahaanba maqan tahay, maadaama kicinta taabashada ee pharynx-ka dambe ay kicin karto fibrillation ventricular vagal reflex.

Dib-u-kicinta wadnaha sambabada (CPR) ee bukaanka hypothermic¶

Ku samaynta CPR ee bukaan-jiifka aadka u daran waxay ku lug leedahay borotokool gaar ah oo si aad ah uga duwan taageerada nolosha caadiga ah ee wadnaha ee caadiga ah.

Hubinta garaaca wadnaha ee 60-ilbiriqsi¶

Heerka Taageerada Nolosha Aasaasiga ah (BLS), hubinta garaaca wadnaha ayaa ku xaddidan 10 ilbiriqsi. Hypothermia, xeerkan waa laga tagay:

Bukaanka aad u qaboojiyey ee ku jira marxaladda III ama heerka IV hypothermia waxaa laga yaabaa inuu yeesho garaaca wadnaha oo kaliya 4 ilaa 8 garaac daqiiqaddii, oo ay la socoto garaaca wadnaha oo aad u daciif ah iyo neefsasho gacmeed oo dhacaya hal mar 30 ilaa 45 ilbiriqsi kasta.

Qaadashada 10 ilbiriqsi oo kaliya si loo hubiyo garaaca wadnaha ayaa u horseedi doonta samatabbixiyeyaashu inay u maleeyaan in bukaanku uu wadnuhu istaagay marka ay dhab ahaantii ilaalinayaan wax soo saarka wadnaha ee nolosha ugu yar.

Samatabbixiyeyaashu waa inay si joogto ah u garaacaan halbowlaha carotid 60 ilbiriqsi iyagoo si dhow ula socda laabta dhaqdhaqaaqa neefsiga.

Haddii wax garaaca garaaca ama neefta kediska ah lagu arko daaqada 60-ilbiriqsi gudahood, ha samayn cadaadis laabta. Bilawga cadaadinta laabta ee garaaca wadnaha hypothermic waxay carqaladayn doontaa laxanka habaysan waxayna kicisaa fibrillation ventricular.

Fulinta CPR hypothermic¶

Haddii, ka dib 60 ilbiriqsi buuxa oo laabasho taxadir leh, aysan jirin gabi ahaanba garaaca garaaca wadnaha iyo dadaal neefsiga, xiritaanka wadnaha ayaa la xaqiijiyay:

Ku billow cadaadin laabta isla markaaba qoto dheer heerka caadiga ah (5 cm ilaa 6 cm/2 inji ilaa 2.4 inji) oo qiimee (100 ilaa 120 cadaadis daqiiqaddii). Darbiga laabta ee qabow, qallafsan ayaa laga yaabaa inuu dareemo adkaansho la yaab leh, oo u baahan dadaal jireed oo joogto ah.

Ku lifaaq Defibrillator Dibadeed Automated (AED) ama kormeeraha wadnaha gacanta. Haddii la ogaado laxanka naxdinta leh (fibrillation ventricular ama tachycardia ventricular pulseless), bixi hal shoog defibrillation ah oo tamar badan leh.

Haddii shoogga hore uu ku guuldareysto inuu soo celiyo laxan habaysan, ha keenin shoog soo noqnoqda haddii heerkulka xudunta u ah bukaanku ka hooseeyo 30 °C (86 °F). Myocardium qabow wuxuu ku dhawaad ​​gebi ahaanba diidaa defibrillation koronto. Rabshadaha soo noqnoqda waxay sababaan kulaylka dhaawaca wadnaha iyada oo aan la beddelin laxanka. Sii wad CPR-ta tayada sare leh oo isku day dib-u-defibrillation kaliya ka dib marka heerkulbeeggu kor u kaco 30 °C.

Jooji daawooyinka caadiga ah ee soo kicinta xididada (sida epinephrine iyo amiodarone) ee ka hooseeya 30 °C. Sababtoo ah beerku ma dheefi karo dawooyinka heerkulka qabow, qiyaasaha soo noqnoqda ee epinephrine waxay ku ururaan sunta dhiigga ee dhiigga. Marka bukaanku dib u kululaado, qiyaasahan la ururiyey ayaa isku mar sii daaya, taas oo kicinaysa vasoconstriction weyn iyo arrhythmias dilaa ah. Marka heerkulka xudunta u ah bukaanku uu dhaafo 30 °C, daawooyinka waxaa la bixiyaa waqti labanlaab ah (6 ilaa 10 daqiiqo kasta) ilaa diirimaadka asaasiga ahi uu soo dhawaado heerarka caadiga ah.

CPR waa in si joogto ah loo ilaaliyaa inta lagu jiro daad-gureynta. Sababtoo ah maskaxda qabow waxay isticmaashaa ogsijiinta ugu yar, bukaanada ayaa si guul leh loo soo nooleeyay iyada oo aan la helin naafonimo neerfaha ka dib in ka badan saacadaha 3 ee farsamada CPR ee joogtada ah.

Hypothermic CPR Decision Rules:
================================================================================
Rule 1: Check carotid pulse and breathing for a full 60 SECONDS.
Rule 2: If ANY pulse or breath is found -> DO NOT COMPRESS; monitor closely.
Rule 3: If no pulse -> Start CPR immediately (100 to 120 compressions/min).
Rule 4: Deliver 1 AED shock if advised; if unsuccessful, defer further shocks
        until active core rewarming raises temperature above 30 °C (86 °F).
Rule 5: Continue CPR continuously; "Not dead until warm and dead."

Dib u kululaynta dibadda ee dadban iyo dib u kululaynta xudunta firfircoon¶

Hababka dib u kululaynta waxa loo qaybiyaa laba qaybood oo kala duwan oo daaweyneed: dib u kululaynta dibadda ee dadban iyo dib u soo celinta xudunta firfircoon. Doorashada habka saxda ah waxay gebi ahaanba ku xiran tahay heerka hypothermia.

Dib u diirin dibadeed oo dadban: Marxaladda I oo keliya¶

Dib u kululaynta dibadda ee dadban waxay si buuxda ugu tiirsan tahay bukaanka wax soo saarka kulaylka dheef-shiid kiimikaadka si uu u diiriyo jidhka:

Habkani wuxuu ku habboon yahay kaliya heerka I (fudud) hypothermia, halkaasoo bukaanku miyir qabo, feejigan, oo si xoog leh u gariirayo.

Doorka samatabbixiyaha ee dib u kululaynta dadban waa in la tirtiro luminta kulaylka deegaanka:

1. Isla markiiba ka saar dharka qoyan oo ku beddel dhar qallalan oo diirran.
2. Ku duub bukaanka bustayaal badan oo dhogor qalalan, bacaha lagu seexdo, ama maro dhogorta leh.
3. Ku dar xayndaabka uumiga ah (daamur weyn oo balaastiig ah, bacda qashinka, ama bustaha bannaan ee mylar) ee ku wareegsan bannaanka dahaarka si aad u joojiso qaboojinta uumi-baxa iyo dhexgelinta dabaysha.
4. Sii cabitaan diirran, kaloori sare leh, cabitaan macaan (kookaha kulul, shaaha sonkor leh, maraq diirran) haddii bukaanku si buuxda u miyir qabo oo si fudud u liqo. Iska ilaali aalkolada iyo caffeine.
5. Heerkulka qallafsan ayaa kor u qaadi doona heerkulka jirka ee udub dhexaadka ah 1 °C ilaa 2 °C (1.8 °F ilaa 3.6 °F) saacaddii.

Dib u kululaynta xudunta firfircoon ee dibadda: ee Marxaladda II¶

Heerka II-hypothermia, gariirku wuu joogsaday, bukaanku ma dhalin karo kulaylkooda. Samatabbixiyeyaashu waa inay bixiyaan tamarta kulaylka dibadeed, laakiin waa in si adag loogu dabaqaa xudunta:

Si toos ah u mari baakadaha kulaylka kiimikaad, dhalooyinka biyaha kulul, ama tuwaalada diirran si toos ah meelaha dhexe ee jidhka: axillae (kilkisha), gumaarka, iyo gidaarka hore ee xabadka.

Marna kulayl ha marin gacmaha, gacmaha, lugaha, ama cagaha. Kuleylinta cidhifyada waxay sababtaa vasodilation durugsan, bilawga dhibicda dambe iyo burburka wareegga dhiigga.

Hubi in dhammaan baakadaha kulaylka ay ku duuban yihiin maro si looga hortago in ay si toos ah taabasho qabow, maqaarka si liidata u cadarsan, kaas oo si fudud u guba.

Samee duubka hypothermia (duubka burrito) oo leh ugu yaraan saddex lakab: lakab gudaha ah oo qoyaan-qaboojiye ah, lakab dhexe oo qaro weyn leh, iyo qolof dabaysha oo dhammaystiran oo aan biyuhu lahayn.

Xudunta firfircoon iyo dib u soo celinta jidhka ka baxsan: ee marxaladaha III iyo IV¶

Hypothermia daran oo qotodheer waxay u baahan tahay habab dib u kululayn oo firfircoon oo gudaha ah oo laga heli karo oo keliya goobaha cisbitaallada sare ee caafimaadka:

Ogsajiinta diirran ee qoyan (kuleyl 40 °C ilaa 42 °C / 104 °F ilaa 108 °F) oo lagu maamulo tuubada endotracheal ama maaskaro dhagan ayaa si toos ah kulaylka u gudbiya sariirta xididada sambabada ee ku dheggan wadnaha bidix.

Dheecaannada crystalloid-ka xididada leh (salin caadi ah ama xal Ringer la nuujiyey) ayaa si sax ah u kululeeyay 40 °C ilaa 42 °C (104 °F ilaa 108 °F). Dheecaannada qabow ee IV waxay ka sii dari doonaan hypothermia; Waligaa ha galin heerkulka qolka IV dareerayaasha xaaladaha qabow ee daran.

Taageerada Nolosha Ka Baxsanaanta (ECLS): Oxygenation Membrane Extracorporeal Membrane (ECMO) iyo Wadnaha Sambabada ee Wadnaha (CPB) waxay u taagan yihiin heerka saxda ah ee daryeelka xidhidhiyaha wadnaha hypothermic.

Dhiiga xididka ayaa laga soo saaraa xididka femoral, waxaana la mariyaa bamka farsamada iyo kulaylka beddelka kaas oo si toos ah u diirriya dhiigga, ogsijiinta siiya, dibna ugu soo celisa habka halbowlaha. ECMO waxay dib u diirin kartaa wadne qabow heer u dhexeeya 4 °C ilaa 8 °C (7.2 °F ilaa 14.4 °F) saacaddii iyadoo la bixinayo taageero dhammaystiran oo hemodynamic ah, taasoo lagu gaaro heerarka badbaadada ee ka sarreeya 70 ilaa 80 boqolkiiba bukaannada aan lahayn jug hore oo neefta ah.

Nidaamyada samatabbixinta degdegga ah ee caalamiga ah iyo daawada buuraleyda¶

Xakamaynta degdega ah ee hypothermia shilalka daran ayaa lagu jaangooyay guud ahaan wakaaladaha samatabbixinta buuraha iyo ururada caafimaadka.

Waqooyiga Ameerika: WMS, AHA, iyo cidlada SAR¶

Gudaha Maraykanka iyo Kanada, borotokoollada hypothermia degdega ah waxaa aasaasay Ururka Caafimaadka Duurjoogta (WMS), Ururka Wadnaha ee Maraykanka (AHA), iyo Wadnaha iyo Stroke Foundation ee Kanada:

Kooxaha goobidda iyo samatabbixinta duurjoogta (SAR) waxay ku shaqeeyaan habab xagal hoose iyo xagal sare leh kuwaas oo ilaalinaya meelaynta joogtada ah inta lagu jiro soo saarista buuraha.

Tilmaamaha Daryeelka Wadnaha ee Degdegga ah ee AHA (ECC) ayaa amraya in dhibbanayaasha hypothermia ee aan garaaca lahayn ay helaan CPR aan kala go' lahayn iyo in loo qaado goobta dhaawacyada ee ECMO awood u leh mar kasta oo suurtagal ah.

Adeegyada degdega ah waxaa lagu gaaraa Maraykanka iyo Kanada oo dhan iyadoo la garaaco 911.

Boqortooyada Ingiriiska iyo Ireland: Badbaadinta Buuraha iyo NHS¶

Boqortooyada Midowday (UK), kooxaha samatabbixinta buuraha (Mountain Rescue England iyo Wales, Scottish Mountain Rescue) waxay ku shaqeeyaan hab-maamuusyo la jaanqaadaya Golaha Dib-u-soo-celinta UK iyo Golaha Buuraleyda ee Ingiriiska:

Helikopterrada samatabbixinta (Diyaarada goobidda iyo samatabbixinta ee HM Coastguard) waxay ku qalabaysan yihiin aaladaha cadaadiska laabta ee makaanikada ah (sida aaladaha LUCAS) kuwaas oo keena cadaadiska laabta ee laxanka ah inta lagu jiro duulimaadka cimilo kacsan.

Adeegga Caafimaadka Qaranka (NHS) xarumaha waaweyn ee dhaawacyada ayaa ilaaliya borotokoollada tooska ah, iyagoo si toos ah bukaannada qaba xanuunka wadnaha ee hypothermic si toos ah ugu gudbinaya qaybaha wadnaha ee gobolka. Soo dirida degdega ah waxaa laga helayaa 999 ama 112.

Alps Yurub: ICAR MEDCOM iyo samatabbixinta buuraha Chamonix¶

Qaaradaha Yurub, gaar ahaan wadamada Alpine (France, Switzerland, Italy, Austria), dawada degdega ah ee buuraleyda waxaa haga Guddiga Caalamiga ah ee Daawada Degdegga ah ee Buuraha (ICAR MEDCOM):

Unugyada samatabbixinta alpine ee gaarka ah (sida Chamonix PGHM ee Faransiiska iyo Air Zermatt ee Switzerland) waxay geeyaan takhaatiirta goobta iyagoo isticmaalaya wiish samatabbixin toos ah goobaha shilalka.

Samatabbixiyeyaashu waxay isticmaalaan geedaha go'aanka hypothermia oo habaysan (dhibcaha RAJADA: Saadaalinta Natiijada Hypothermia ka dib ECLS) si loo go'aamiyo bukaanada garaaca la'aanta ah ee leh suurtogalnimada badbaadada sare ee heerarka potassium ee serum, heerkulka asaasiga ah, iyo heerka neefta.

Dhammaan dalalka xubnaha ka ah Midowga Yurub, gurmadka degdegga ah waxaa lagala soo xiriiri karaa 112.

Australia iyo New Zealand: Alpine SAR iyo NZRC¶

Australia iyo New Zealand, tilmaamaha hypothermia waxaa kormeera Golaha Dib-u-soo-nooleynta Australia (ARC) iyo Golaha Dhaqancelinta ee New Zealand (NZRC):

Kooxaha samatabbixinta iyo goobidda Alpine ee ka hawlgala Buuraha Barafka leh ee New South Wales, Victorian Alps, iyo Koonfurta Alps ee New Zealand waxay la kulmaan hypothermia si lama filaan ah inta lagu jiro duufaannada dabaylaha wata.

Nidaamyada deg-degga ah waxay xoogga saaraan helikabtarrada jiifka ah ee boodboodka iyo duubista xudunta firfircoon. Australia gudaheeda, diritaanka degdega ah waxa loo wacaa 000; New Zealand, wac 111.

Su'aalaha soo noqnoqda¶

Waa maxay dhab ahaan hypothermia ifafaale ka dib?¶

Afterdrop waa qaboojinta joogtada ah ee xubnaha gudaha ee xudunta u ah, oo ay ku jiraan maskaxda iyo wadnaha, ka dib markii bukaanka la samatabbixiyey ama xilliga hore ee dib u kululaynta. Waxay dhacdaa sababtoo ah kulaylka jidhku wuxuu sii wadaa inuu kulaylka ka soo baxo gudaha dibadda una guuro unug qabow, iyo sababtoo ah kululaynta gacmaha iyo lugaha qabow waxay balaadhiyaan xididdada dhiigga, taasoo keenta baraf, dhiigga xididdada aashitada ah ee ka yimaada cirifka si ay dib ugu soo noqdaan wadnaha, taas oo kicin karta wadnaha oo degdeg ah.

Waa maxay sababta dhaqdhaqaaqa qallafsan uu khatar ugu yahay qof qaba hypothermia daran?¶

Marka wadnaha bini'aadamka uu qaboojiyo ka hooseeya 30 °C (86 °F), muruqa wadnaha iyo habka korantada ayaa noqda mid kacsan oo aan degganayn. Maareynta adag, kacdoonka, isbeddelada booska degdega ah, ama u oggolaanshaha bukaanku inuu si farsamaysan u socdo waxay culaysisaa darbiga wadnaha qabow, taasoo kicinaysa isla markiiba, fibrillation ventricular dilaa ah. Samatabbixiyeyaashu waa in ay dhibbanayaasha heerkulbeeggu ku qabtaan dabacsanaan qalliin oo xad dhaaf ah.

Maxay samatabbixiyeyaashu u hubiyaan garaaca wadnaha muddo 60 ilbiriqsi buuxa ah xilliga hypothermia?¶

Marka lagu jiro hypothermia ba'an, garaaca wadnaha iyo neefsashadu si weyn ayay u gaabiyaan si loo ilaaliyo tamarta dheef-shiid kiimikaadka. Bukaanku waxa laga yaabaa in uu garaaco garaaca wadnaha oo kaliya afar ilaa lix garaac daqiiqaddii, oo ay la socdaan dhawaqyo wadne daciif ah iyo neefsasho gacmeed oo ay kala soocaan hakadyo dhaadheer. Hubinta toban ilbiriqsi oo kaliya waxay u horseedi doontaa samatabbixiye inuu u qaato in qofku aanu garaac lahayn, iyo samaynta cadaadiska laabta ee wadnaha garaaca waxay kicin kartaa wadnaha oo istaaga.

Waa maxay sababta aadan weligaa baakadaha kulaylka u saarin gacmaha ama cagaha dhibbanaha qabow?¶

Xirmooyinka kulaylka oo si toos ah loo saaro gacmaha ama cagaha waxay diirisaa xididdada dhiigga ee durugsan, taasoo keenaysa inay si degdeg ah u balaadhaan. Tani waxay u oggolaanaysaa in la isku ururiyo, barafaysan, dhiigga aashitada ee ka imanaya cidhifyada inuu si degdeg ah ugu soo laabto xudunta jidhka oo si toos ah u galo wadnaha, isagoo soo da'aya dhibco khatar ah iyo shoog soo noqnoqda. Xirmooyinka kulaylka dibadeed ee firfircoon waa in lagu dabaqaa oo keliya meelaha xudunta u ah: kilkilaha, gumaarka, iyo laabta.

Maxay ka dhigan tahay odhaahda "qofku ma dhiman ilaa uu diirimaad oo dhinto" macnaheedu?¶

Xeerkan caafimaad waxa uu macnihiisu yahay in bukaan aad u heersare ah oo u muuqda in uu gabi ahaanba dhintay, oo aan lahayn garaaca garaaca, neefta oo aan lahayn, arday go'an, iyo addimada adag, waxa laga yaabaa in uu weli haysto maskax iyo wadnaha la badbaadin karo. Qabowga daran wuxuu unugyada ka ilaaliyaa ogsijiin yarida. Bukaanka ku jira xiritaanka wadnaha hypothermic waxay sameyn karaan soo kabasho buuxda oo neerfaha haddii dib u soo kicinta wadnaha sambabada la joogteeyo ilaa xudunta si firfircoon dib loogu soo celiyo isbitaal.

Shahaadada gargaarka degdega ah¶

Maareynta hypothermia shilalka daran waxay u baahan tahay aqoon caafimaad oo gacan-ku-jir ah, degenaansho jireed, iyo u hoggaansanaan adag hab-maamuuska fudud ee maaraynta. Ogaanshaha sida loo qiimeeyo xaaladda maskaxeed ee qabow-sababtay, la sameeyo jeegareynta garaaca wadnaha 60-ilbiriqsi, fulinta uumiga-barrito duubka dahaaran, iyo bixinta cadaadis laabta joogtada ah inta lagu jiro gaadiidka daba dheeraaday waxay badbaadin kartaa nolosha xaaladaha degdega ah ee jiilaalka iyo cidlada.

Waxaan si adag ugu dhiirigelinaynaa dhammaan madadaalada bannaanka, xiiseyaasha isboortiga jiilaalka, iyo jawaabeyaasha bulshada ugu horraysa inay helaan shahaado la aqoonsan yahay ee gargaarka degdegga ah ee cidlada (WFA) ama gargaarka degdegga ah ee caadiga ah iyo soo kicinta wadnaha sambabada (CPR). Bixiyeyaasha la aqoonsan yahay sida Laanqayrta Cas ee Maraykanka, St John Ambulance, Laanqayrta Cas ee Ingiriiska, iyo Laanqayrta Cas ee Kanada waxay bixiyaan tababar dhamaystiran oo ku saabsan daryeelka hypothermia deegaanka, dib u soo celinta asaasiga ah ee firfircoon, iyo xasilinta taageerada nolosha.
